TODAY’S WEATHER DISCUSSION AND FORECAST:



Today’s Forecast for Crestline, Twin Peaks, Lake Arrowhead and the San Bernardino Mountains:
Good Morning.
Yesterday the temperatures really warmed up across the area. Valley of the Moon in the Crestline area reported 77* for the days high. San Bernardino had 90*, and the Fire Station in the Deer Lodge Park area reported 76* for the high there. This was due to the area of High pressure that was over SoCal reaching it’s peak. Today, the Ridge of High pressure is moving East, and a weak trough will follow. Temperatures today will be much cooler as High clouds at around the 20-30k’ level will shield most of the Sun’s heat. Highs today area expected to be from 8-12* cooler than yesterday. Also, we have had a change in wind direction, yesterday we had a weak offshore flow, today we will see an increase in Southerly flow as a mesoscale Low passes through the area tomorrow. For the Easter Sunrise Services around the Mountain, temperatures will be in the mid 40s at both Lake Arrowhead and Lake Gregory. Big Bear will be in the upper 30s to low 40s there. We should see light winds from the South West from 5-10mph throughout the day tomorrow. Late Sunday night or early Monday morning, fog will likely develop along the west facing slopes
below the 4500′ level. So plan a little extra time if you are driving down the hill. Tuesday, we will begin to warm up as a more Zonal flow returns through Friday. Next weekend there will be a decent trough of Low pressure move onshore along the West Coast of California. Rain will be likely for most of the State. Here in SoCal we, as always, will be on the bottom of the Trough, so we will see a chance for a shower as it looks this morning. Don’t hold your breath though, it is still a long way out. Just a heads up as what we may see for next weekends weather. Overall, the weather for the upcoming work week looks pretty nice. Spring has arrived and the possibility of inclement weather will lessen as we close out March, and April takes hold. This time of year is known to meteorologists as the Spring unpredictability Period. This is when the Forecast models have the most problems with the longer range model forecasts. Happy Easter to all and enjoy the nice mountain weather. RC
Also, in Twin Peaks at the entrance to Strawberry Lodge on HWY 189, check out the daffodils that are now in bloom, please don’t pick them, as they are in tribute to a local Mom (Julie Greer) who passed away several years ago from cancer. Her Husband Tom, and friends, plant and maintain these flowers in her remembrance. Thank you.

Temperatures around the area for Today and overnight:
Crestline, Twin Peaks, and Lake Arrowhead: 63-67*/40-46*
Running Springs, GVL, and Big Bear: 60-65*/36-43*
San Bernardino: 80-84*/55-60*
That’s it for now, have a good day, and thanks for joining me @ lakegregoryweather.com. RC

TODAY’S WEATHER DISCUSSION AND FORECAST:



Today’s Forecast for Crestline, Twin Peaks, Lake Arrowhead and the San Bernardino Mountains:
Good Morning.
If you liked the weather yesterday, you’ll love today! Surface pressure from the San Diego to Daggett is running slightly onshore this morning. A 1022mb area of High pressure over the Great Basin will slowly build today before moving East tonight. This will give us one more day of above normal temperatures locally. Then a quick moving trough will pass through Saturday and Sunday. This will generate a stronger onshore flow with clouds and fog increasing along the Coast and the Inland Valleys. Behind the trough, a 1028mb area of High pressure will develop off the California Coast early next week while the surface pressure in the interior of California will be much lower. Continuing the onshore flow through the work week ahead. High clouds will be most of what we see here from the passing trough with gusty SW winds. There may be some morning Ridge Fog Monday as we start the new workweek. Also temperatures will be from 7-12* lower for the weekend with highs expected to be in the upper 50s to low 60s for the weekend. On the long range outlook, the next chance for rain will be around the 6th of April. That’s it for today. Thank you for joining me @ lakegregoryweather.com

Today’s Forecast for Crestline, Twin Peaks, Lake Arrowhead and the San Bernardino Mountains:
Good Morning.
Yesterday was a picture perfect day around the mountain! Warm temperatures, clear skies with little to no wind made for a very nice day. Today will be much the same. A ridge of High pressure will continue to build over the West, bringing in more very nice weather through the weekend. Temperatures will peak Friday locally then slowly cool a few degrees as a weak trough slides through Sunday. Temperatures will remain at or about normal for this time of year through early next week. So your weekend plans will be fine for any outdoor activities. Along the Coastal areas, there will be some morning fog and low clouds, but that should clear out by late morning in those areas. A zonal flow will develop early next week so the weather outlook on the longer range, looks good through at least mid week next week. Last night when I was looking at the long range outlook, one model shows a chance for rain in SoCal around April 6th~. So that I will be watching. Other than that, enjoy the nice weather just in time for Easter, or Spring break!

TODAY’S WEATHER DISCUSSION AND FORECAST:



Today’s Forecast for Crestline, Twin Peaks, Lake Arrowhead and the San Bernardino Mountains:
Good Morning.
The gusty winds from yesterday have all but gone by the wayside this morning. The only location I could find fairly strong winds this morning were at Heaps Peaks at 15-30mph. All of the other local Weather Stations had light winds, including Waterman Canyon.
Today’s weather will be very nice as high pressure expands over the West Coast from the Pacific Ocean. The area of Low pressure that brought gusty winds to the area, has moved far enough to the East, that it is no longer a factor. Along with the High pressure over the area, warmer temperatures, with a gradual return to onshore flow, will be the forecast through Saturday. Temperatures for the mountain areas will be a few degrees warmer today, and again tomorrow. Saturday, we will continue the mild weather with some cooling for the weekend, as onshore flow takes hold across SoCal. The Coastal areas will see morning fog along the coastline over the weekend and we may see a few clouds as well due to a weak area of low pressure that will pass close to the area. Overall, zonal flow aloft will keep our weather very pleasant for the next 5 to 7 days. At this time, I don’t see any rain for our area in the 10day outlook. So enjoy the nice mountain weather as Spring has sprung! Also, in Twin Peaks at the entrance to Strawberry Lodge on HWY 189, check out the daffodils that are now in bloom, please don’t pick them, as they are in tribute to a local Mom (Julie Green) who passed away several years ago from cancer.
Temperatures around the area for Today and overnight:
Crestline, Twin Peaks, and Lake Arrowhead: 60-64*/42-46*

Good Morning.
Gusty North East winds are blowing across the area this morning. Gusts from 10-41mph are currently as of 5am being reported across the area.
Most of the higher winds are along the Ridges this morning. Waterman canyon has winds from 6-20mph, so expect gusty winds on the local HWYs this morning.
These winds will continue through mid day today before tapering off by this afternoon.
Clear skies and slightly warmer temperatures will be the days forecast. High pressure over the Pacific will strengthen today over the area bringing in a warming trend through
Friday. The gusty North East winds will subside, as Low pressure currently over Arizona, continues to move East. This mornings surface pressure gradient from Tonopah to San Diego is running at close to 8mbs. This will likely peak at 10mbs this morning then begin to weaken later today. As this develops, the NE winds will peak this morning, then die down later today following the surface pressure gradient between Tonopah and San Diego. Friday, onshore flow will return to the area as the High weakens. Cooler temperatures for the weekend is likely but it will still be in the upper 50s to low 60s. No rain is in the 5-7day forecast as of this morning.

TODAY’S WEATHER DISCUSSION AND FORECAST:



Today’s Forecast for Crestline, Twin Peaks, Lake Arrowhead and the San Bernardino Mountains:
Good Morning.
This morning we still are under the influence of a long wave trough that is slowly moving East. As the trough moves East today, we will pick up North East winds from a combination of High pressure over the Eastern Pacific, and the departing Trough. Gusty winds will be the main weather story today. North East winds will be blowing locally, and especially in and along the canyons, with gusts from 15-40 mph by this evening. These winds will continue through Tuesday night before subsiding. Local wind gusts so far this morning are; Heaps Peak 17-23mph, Waterman Cyn; 5-12mph, and Running Springs; 15-25mph. All from the NE.
We will have clear skies today but cool temperatures will continue through Tuesday, due to cold air advection from the Great Basin. Daytime Highs will run from the 40s to low 50s for the first part of the week, then warm up to the 60s by Thursday. Big Bear and the surrounding areas there, will be a little cooler with highs in the 50s by the end of the work week. Temperatures in the Valley will be close to the 80* mark by Thursday! Then we will have a slight cooling trend as onshore flow returns to the area. On the long range outlook, there are no storms for the SoCal area for the next 5-7 days as it looks this morning. However, don’t put away your Winter items just yet. There will be a chance to return to a wet pattern by the second week of April. that is too far out to be sure of anything, but that’s how it looks this morning.

TODAY’S WEATHER DISCUSSION AND FORECAST:



Today’s Forecast for Crestline, Twin Peaks, Lake Arrowhead and the San Bernardino Mountains:
Good Morning.
Fog and low clouds will be with us for most, if not all of today. Temperatures will be very cool as well. Yesterday, the forecast was for a chance of rain/snow for the local area either overnight or early morning today. This was due to an area of Low pressure that was slowly moving South along the West Coast. As the Low did move South along the West Coast, it lost most of the energy it had. So as it arrived here, all that was left was what we have this morning, Clouds and Fog. Along the Rim, drizzle and areas of thick fog can be expected for most of the day today. As you get North of the Rim, there will be some clearing this morning and more later today.
Now for the rest of the story. It looks like we have broken out of the cycle of low pressure systems funneling into the SoCal region. As this current area of low pressure moves out today, High pressure will build over the Pacific Ocean to our West. Additionally, an upper level Low will position itself over Arizona, thus, a North East flow will develop for Monday and Tuesday here. Monday and Tuesday, gusty Santa Ana type winds from 20-45mph can be expected, with the highest gusts along the Rim and in the local canyons. However, don’t get to excited. Due to a cold area of High pressure over the Great Basin, temperatures here will remain cool through Tuesday as cold air advection riding in on the NE winds will be our dominate weather feature. Wednesday, all of that will move East and we will begin a warm up through at least Friday, with only minor cooling for the Easter weekend. Thursday through Sunday, temperatures will be in the upper 60s to 70* for the Crestline, and Arrowhead areas. Running Springs, Big Bear, and Green Valley Lake, will see temperatures in the low 60s, and San Bernardino will be close to 80* all for the same time period.
I can remember lots of Easter Sunrise services that were very cold and foggy. So it looks like this year the weather will cooperate. So overall, as we progress through the week ahead, we will see improving weather for the mountain areas. It’s hard to believe that March is almost over. Have a good day and enjoy the great Mountain weather. RC

Temperatures around the area for Today and overnight:
Crestline, Twin Peaks, and Lake Arrowhead: 38-45*/25-34*
Running Springs, GVL, and Big Bear: 36-42*/22-32*

Today’s Forecast for Crestline, Twin Peaks, Lake Arrowhead and the San Bernardino Mountains:
Good Morning.
We just can’t seem to break out of this pattern, fog, and clouds have moved back in below the 6000′ level this morning. This is another weak wave that is from an area of Low pressure to our North. Fog and drizzle along the Rim will make for poor driving conditions this morning. Cold air advection from the Great Basin, as well as a pool of cold air from the approaching Low pressure area to our North, will keep temperatures below normal for the next couple of days. We should see a brief clearing later today as wave number one passes through. Then wave number two will arrive later this evening, there will be a chance for a rain shower, or snow shower, overnight as #2 passes through the area. The freezing level is expected to be around 5500’to the 6000’level tonight. Tomorrow temperatures will continue to be below normal with clouds, and fog, along the Rim again. Then we will clear out late afternoon, but one more weak trough will pass through SoCal Monday. As the last trough passes on Monday, North East winds will develop as High pressure develops over the Great Basin. The pressure gradient will be around 10mbs as it looks this morning, so expect gusty NE winds Tuesday as well. Wednesday through the end of the work week ahead, temperatures will begin to rise and the North East winds will subside. Above normal temps will move over SoCal as High pressure over the Eastern Pacific sets up. By next weekend, daytime highs in the San Bernardino area could reach 80*, just in time for Easter Sunday.
On the ECMWF (European Model) long range outlook, after this series of weak system pass through by Tuesday, it looks like that will be it for the rest of the month and the first part of April. So be patient, Spring weather will arrive very soon.

Temperatures around the area for Today and overnight:
Crestline, Twin Peaks, and Lake Arrowhead: 40-46*/30-35*
Running Springs, GVL, and Big Bear: 40-45*/23-28*

TODAY’S WEATHER DISCUSSION AND FORECAST:



Today’s Forecast for Crestline, Twin Peaks, Lake Arrowhead and the San Bernardino Mountains:
Good Morning.
After a nice rain yesterday, today we will have clearing skies as the area of low pressure moves East. We will be on the back side of the slowly departing low, so clearing will be slow today. Fog and clouds have shrouded the Rim and will also be slow to clear. Another weak wave, or trough will pass through SoCal Saturday afternoon. This will bring a slight chance for a snow shower to the areas above the 5000′ level by Sunday morning. The AR that was the big concern for possible flooding in the Fire areas, has moved out of the area to the South, and will not be a factor in the near future. On the long range outlook for SoCal, a warming trend will begin Tuesday as High pressure returns to the West Coast. Temperatures will be above normal by mid week next week.
Rainfall amounts around the area were pretty impressive, though not as much as were originally forecast. Remember, the NWS forecasts weather for all of SoCal, not just, or only, the local area, so when they say rainfall amounts of 5-10″s are possible, that is a generality for the SoCal region. That would be an amount that could fall somewhere in the forecast area.
The San Diego NWS watch area is from the Mexican border, to Eastern San Bernardino, to South LA. That area has a variety of Topography and landscape. Locally, we have several specific anomalies that affect the weather and rain/snowfall here in the Crestline to Big Bear areas. Thunderstorms can and will occur near Big Bear, when Arrowhead and Crestline, have none. Snow may fall here in Crestline, and Big Bear may be clear. So, remember, NWS Weather Forecasters are trying to cover the whole picture so you know what to expect at the worst case scenario. This is where I come in. I try to hone the forecast to fit the local area while considering the local anomalies, and adjusting for that. I spend two to three hours each day beginning at 3am on normal work days going over the same maps, charts, Satellite pics, etc, that they do. I look for small scale anomalies that will affect the local weather here as opposed to the large scale forecast picture for all of the West Coast.
The storm rainfall total at my location was 3.05″. Skyland Drive Wx/St reported 2.96″ and the North side of Arrowhead reported 1.64″ at North Grass Valley Road, Sky Forest reported 1.35″ and Big Bear had 1.25″. So you can see that the rain was varied across the general area. Below is a more comprehensive rainfall and temperature recap from the last 24hrs.
I have been having issues with the internet, and my computer this morning, so I’m a little late with this. Sorry for any inconvenience. RC
Temperatures around the area for Today and overnight:
Crestline, Twin Peaks, and Lake Arrowhead: 50-55*/32-36*
Running Springs, GVL, and Big Bear: 45-50*/24-34*

TODAY’S WEATHER DISCUSSION AND FORECAST:



Today’s Forecast for Crestline, Twin Peaks, Lake Arrowhead and the San Bernardino Mountains:
Good Morning.
The rain has finally moved into the area this morning. Yesterday a band of showers moved through the area during the afternoon then quit around 3pm. Overnight, the Low to our North began to drift South, and now we are getting the rain that has been forecasted for the past several days.
Rainshowers will increase in intensity this morning, as the front moves closer to SoCal. Rainfall estimates for the local area are from 2-5″. The greatest amounts will be along the Rim due to orographic lift. South West to South East winds will pick up today as the system moves closer with wind gusts from 15-35mph expected locally. Some locally stronger gusts along the Rim can be expected from 15-45mph in the more wind prone areas.
The heaviest rain will be from 11am through 5pm today. The Atmospheric River (AR) will begin to dissipate today as this system moves through. This will decrease the overall amount of expected rain for the area. Down from yesterday’s 5-10″ forecast for the local mountain areas to 2-5″ as mentioned above.
Showers will taper after 5pm and should end all together by Friday at 6am. As the Front passes through tonight, there will be a chance for a Thunderstorm as the cold air from the Low meets the warm Tropical air. On the GOES WEST Satellite this morning, it looks like a few Thunderstorms may be forming toward the back of the front over the Pacific. That will move through here this evening. The snow levels will be above 8000′ through the bulk of the storm, then dropping as the cold low passes through. This is when Big Bear, Green Valley Lake, and even Running Springs, may see a few snow flurries.
As of 5am this morning, rainfall amounts have been running about .25-.45″ across the area.
Saturday night into Sunday morning, another wave of moisture will pass through SoCal. This will be much colder than todays storm with a chance for snow to the local area above the 5000′ level. At this time, this doesn’t appear to have much of a punch associated with it. More on that tomorrow. For next week, Tuesday and beyond, High pressure will return along with warmer temperatures as well. Fog, Rain and wet roads will make for poor driving conditions today. Plan a little extra time for your travels today and watch for Road Crews clearing debris too!
Temperatures around the area for Today and overnight:
Crestline, Twin Peaks, and Lake Arrowhead: 43-48*/34-38*
Running Springs, GVL, and Big Bear: 42-46*/28-34*
San Bernardino: 62-65*/46-52*
