TODAY’S WEATHER DISCUSSION AND FORECAST:


Today’s Outlook for Crestline, Twin Peaks, Lake Arrowhead and the San Bernardino Mountains.

Good Morning.
Yesterday brought a variety of weather to the local area. Heavy Rain, Flooding, Washed out roads, Hail, and even snow to the higher elevations. A convective storm blew through the Arrowhead and Crestline areas around 2pm yesterday which brought a variety of weather and problems to the area. This is why we all need to be prepared for Winter driving this time of year as things can, and will change rapidly.
Today we will have clearing weather as yesterday’s system moves out. Currently, there is fog along the Rim, so plan a little extra time if you are headed down the hill. We will be in between systems today and tomorrow morning. For tomorrow afternoon, a quick moving weak system will pass through the area bringing a chance for snow showers to the area. Sunday we will clear out as High pressure moves into the West. The next storm series will arrive Wednesday or Thursday. Have a good day.
That’s it for now. Thank you for joining me @ lakegregoryweather.com RC

TODAY’S WEATHER DISCUSSION AND FORECAST:


Today’s Outlook for Crestline, Twin Peaks, Lake Arrowhead and the San Bernardino Mountains.

Good Morning.
As of 2am, light rain has begun falling across the area. This will be the trend for today as a Pacific Storm moves into SoCal. Rain becoming heavy after 9am through ~5pm will be the forecast. Cloudy with fog along the Rim can be expected today and tonight. The snow or Freezing level will start out at around the 7500′ level this morning, Lowering tonight to around the 6500′ level. By the time the freezing level drops locally, the bulk of this system will have passed. However at the higher elevations, 3-5″ of the white stuff could fall. That would be for the Big Bear and Green Valley Lake areas etc, above the 6500′ level. From the 4500′ level to the 6000′ level, rain and a few snow flurries will be possible by late this afternoon or this evening with little to no accumulations expected. There will also be a slight chance for a Thunderstorm this afternoon as the Front works its way through the area. If that does occur, we could see hail or soft snow pellets to the lower elevations for a short period while the T-Storm passes. Winds today will be picking up as the system winds up and passes through. Gusts from 10-35mph will be likely at times with higher gusts in the wind prone areas. Estimated storm totals for rainfall are from 1.5″-4.00″ across the area. The west facing slopes will see the most rainfall as orographic lift takes place there. Rain will taper off tonight with a few showers remaining for Friday am as the system clears out. Saturday another weaker system will work its way through with colder temperatures and a better chance for snow at the resorts. Sunday we will see clearing asn High pressure rebuilds but more rain is in store for the middle of next week and more snow likely as it looks to be a colder system. Temperatures will remain quite cool through the period. That’s it for now. Thank you for joining me @ lakegregoryweather.com RC

Atmospheric
River Thursday


TODAY’S WEATHER DISCUSSION AND FORECAST:


Today’s Outlook for Crestline, Twin Peaks, Lake Arrowhead and the San Bernardino Mountains.

Good Morning.
This morning we have clear skies along with light and variable winds. The Pressure Gradient from Tonopah to San Diego has weakened overnight so the NE winds have pretty much moved on. There will be some residual gusty winds in the canyons and the ridges this morning but those too will subside by later today. Daytime temperatures today will be a little warmer due to the lack of winds. Change is coming. Later today, High Clouds will begin to move over SoCal as an area of Low pressure moves onshore to our North. Winds will change to the SW and begin to increase by late tonight or tomorrow morning. As this system moves Inland and drops South, we will see increasing clouds and fog developing along the Rim with light rain beginning by late tomorrow. This system has lots of cold air with it however as it arrives in SoCal, a warmer Atmospheric River will supply added moisture to it and keep the freezing levels high for most of the storm. Rainfall totals will run from 1.00″-3.00″s with some areas receiving more due to orographic lift along the West facing slopes. Strong and gusty winds, Fog, with Heavy Rain at times can be expected especially early Thursday morning through around 2pm. The freezing level will lower toward the end of the storm so the elevations above the 6500′ level will likely see some accumulation of 1-4″ possible. Snow flurries or snow pellets will be possible to lower elevations due to convective activity as the front passes. Thunder and Lightning will be possible as well. The PWAT levels will reach from 1.00-1.50″ early Thursday morning. This is when we will have the heaviest rain as it looks this morning. Friday will be a day of clearing but, another weaker system with colder air is in line for Saturday and Sunday morning. High pressure will build in to the West Monday through mid week then we may see another system for late in the work week.
That’s it for now. Thank you for joining me @ lakegregoryweather.com RC

TODAY’S WEATHER DISCUSSION AND FORECAST:


Today’s Outlook for Crestline, Twin Peaks, Lake Arrowhead and the San Bernardino Mountains.

Good Morning.
If you like weather, you’ll like this forecast!
Today, we will be under a Ridge of High pressure, so we will see NE winds developing as the day wears on. Gusty NE winds from 10-30mph especially in the canyons and along the Ridges as well as clear skies, will be the forecast for today. Tomorrow, the winds will subside and become onshore as a Trough of low pressure moves onshore in NorCal with rain/snow spreading South toward SoCal. Wednesday, increasing clouds, gusty winds, with Ridge fog developing later in the day along with rain beginning in the afternoon, and lasting through Thursday. Rainfall estimates for our area are from ~1-3″ of rain. The snow level will start at around 7800′ then lower to around 6200′ Thursday afternoon. However by the time the snow level lowers the bulk of this system will be over. Friday we will in between systems with clearing skies and cold temps. Saturday, system #2 will arrive bringing more rain with colder temperatures. The snow level for this system will be down to around 6500′. This system is colder and won’t have as much moisture with it so rainfall amounts will be under and inch. This storm will clear out Sunday but temperatures will remain cold. The next system will arrive Tuesday/ Wednesday. If this pans out, the storm for Wednesday/Thursday will bring lower snow levels to the area with snow to the ~5000′ level as it looks this morning. And so on. So if you like Winter weather, it looks like we are in for a wet period locally. Enjoy!
The rain expected Thursday should put an end to the Fire Season of 2018. Thankfully!

Please watch these as they are very informative as to why we have such a wildfire problem, and also a view from ground zero from Paradise, CA.

Thursday


TODAY’S WEATHER DISCUSSION AND FORECAST:


Today’s Outlook for Crestline, Twin Peaks, Lake Arrowhead and the San Bernardino Mountains.

Good Morning.
This morning a weak Trough will pass over SoCal bringing light fog along the Ridges around the 4000-5000′ level along with high clouds. Later today as the Trough passes, High pressure will move into the Great Basin area creating a pressure gradient that will bring NE winds across SoCal. Currently, Paivika Ridge in the Crestline area near where the Hang Gliders take off from, the Weather Station there is reporting NE winds from 15-25mph. As the day goes on, we will see increasing NE winds to the lower elevations reaching into the Canyons along the local HWYs and into the Valley. This will increase the Fire Danger levels locally however due to the recent rain, Critical levels will not be likely from this short wind event. The gusty NE winds will taper off by Monday night then becoming Onshore Tuesday. Onshore flow will strengthen Tuesday in advance of what looks like a strong weather system now over the Pacific. Rain and snow at the higher elevations will move onshore late Tuesday to our North then spread South arriving here late Wednesday into Thursday, and possibly Friday before it clears out. Rainfall totals from this system will be from 1.00-2.00″ as it looks this morning. The snow levels locally are forecast to be from 6800′ and above Thursday and Friday. But, there is a fly in the ointment, an area of High pressure is forecast to develop just South of SoCal. If this does in fact develop, we will see a warm flow of Tropical moisture, Atmospheric River,(AR) enhancement to our Rainfall from this Thursday which will raise the freezing level and bring more rain to the area. This I will be watching in the coming days as the model forecasts hone in on this system. The weekend behind this system looks iffy as well. The GFS and the ECMWF forecast models are not in agreement on the longer range outlook. So we may pick up another system Saturday or Sunday, and again mid week into December. The rain expected Thursday should put an end to the Fire Season of 2018. Thankfully!

TODAY’S WEATHER DISCUSSION AND FORECAST:


Today’s Outlook for Crestline, Twin Peaks, Lake Arrowhead and the San Bernardino Mountains.

Good Morning.
This morning we have clear skies across the Mountain above the 4500′ level. Fog is slowly creeping up the canyons from the Valley and may spill over into the Crestline area later this morning. HWYs 18 and 330 will have foggy conditions below the 4500′ level this morning, so plan accordingly. A weakening short wave is passing across SoCal this morning along with a weak onshore pressure gradient is pushing moist maritime air across the Inland Valleys from the Coast. This will clear out by early this afternoon. Behind the trough as it departs the SoCal region, Higher pressure will build into the Great Basin. This will bring a wind direction change by Sunday afternoon through Monday night. Santa Ana winds will return through that period with winds gusting from 10-40mph in the wind prone areas. However, due to the recent rains, the Fire Danger levels will not reach the Critical stage as in the recent past. By Tuesday, we will return to an onshore flow as several wet Weather systems line up to bring possibly substantial rains to the West Coast of California. Locally, rain will be likely by Wednesday night or Thursday early morning. This system could linger through Saturday bringing several inches of rain with some snow to the higher elevations. This is still too far out to put down numbers but, it looks like we will possibly be in for several wet systems through the middle of December. Again, long range outlooks are subject to change, and are in what I call the crystal ball zone, but the long range outlooks are in pretty good agreement on this. So maybe we will actually see a wet beginning to our Winter Season locally.

We have Clear skies across the mountain this morning, with fog to the 4000′ level below. Onshore flow will be with us through Sunday morning with morning fog likely in the Valley for the same time frame. Rainfall totals were pretty good across the mountain. Crestline-.78″, Twin Peaks-.75″, Lake Arrowhead-.52″, Running Springs-.60, Big Bear-.26″ San Bernardino-.35″. Temperatures will remain cool with daytime highs from 50-58* below 5000′, and from 48-55* above 5500′. No snow fell locally as the warmer Tropical moisture from the South aided the rainfall locally. Today we are between the Tropical moisture to our South, and another weak Trough to our North. An area of Low pressure will slide through the Interior of California tomorrow. This will aid in the onshore flow locally through Sunday. There will be a very slight chance for a sprinkle in some areas tomorrow as the Trough passes through the area. Mostly just a deeper Marine layer with drizzle. After the Trough passes through the Great Basin by Sunday morning, higher pressure will develop there. This will bring a return of a 24-36hour period of Santa Ana winds across the SoCal region for late Sunday night through early Tuesday morning. Temperatures will likely remain very cool due to cold air advection from the North mixing with the NE winds. Then another change will begin to develop. Onshore flow will return Tuesday afternoon as a series of systems begin to affect the West Coast of California. Wednesday we should see clouds beginning to move into the local area with rain spreading South through SoCal Thursday. Beyond Thursday is just to far out into crystal ball territory, but it looks like there will be a chance for more systems into SoCal after that. That’s it for now.

TODAY’S WEATHER DISCUSSION AND FORECAST:


Today’s Outlook for Crestline, Twin Peaks, Lake Arrowhead and the San Bernardino Mountains.

Good Morning.
Happy Thanksgiving. I hope you all have a great Day!
Overnight, rain moved into the area from the south. As I had mentioned on yesterday’s blog, a plume of moisture has moved in from the South bringing enhanced rainfall to the area. As of 5:30 am, I have received .88″ so far at the South shore of Lake Gregory, Twin Peaks-.70″, and Lake Arrowhead-.48″. Fog and low clouds are hugging the Rim as can be seen on the lakegregoryweather.com webcam page. The rain will end early this morning leaving partly cloudy skies with fog in some areas throughout the day. Temperatures ended up being warmer than forecast due to the warmer Sub Tropical air mixing in with the area of Low pressure from the North. So snow levels are much higher than hoped for locally. Temperatures today will be in the 40s to low 50s as the Trough clears out. We will continue to have a slight chance for an occasional Rain shower on and off through today, and for the next couple of days as a couple of weak waves pass through the area. Sunday we will be on the back side of a Trough which will bring back a short period of Offshore winds. Fortunately the rain will help to keep the fire danger levels down. On the longer range outlook, there’s a chance for several systems to move into the SoCal region beginning next Friday. If you are traveling today, be careful as this is the first real rain and rocks and debris are likely to be on the local roads. Also fog and low clouds will slow the drive around the area. So plan a little extra time to get to your destinations. That’s it for now. Thank you for joining me @ lakegregoryweather.com RC

TODAY’S WEATHER DISCUSSION AND FORECAST:


Today’s Outlook for Crestline, Twin Peaks, Lake Arrowhead and the San Bernardino Mountains.

Good Morning.
Today will be a transitional day as we head into our first Winter type storm. This morning’s surface pressure from the Desert to the Coast is pretty much neutral. As the day goes on, we will see increasing winds from the South to South West as a trough of Low pressure moves onshore in NorCal. High clouds will start the day today, then lower clouds and possibly fog along the Rim by this evening through tomorrow morning, as a pretty good chance for rain showers moves toward the area. A Frontal band of showers will arrive later tonight through tomorrow morning, if it all holds together. Rainfall estimates are running from .25-.75″ for the local area. Most of the rain will fall from the West facing mountain slopes to the Coast from this storm. Thursday will partly cloudy with a couple showers likely through the morning hours. Snow flurries or showers will be possible for the higher elevations above the 6800′ level. This is a good time to check out your Winter Driving gear! Gusty SW winds and cool temperatures will give the Holiday a nice late Fall like feeling. I wish everyone a nice Thanksgiving Day! Friday will be very Fallish as another weak frontal boundary moves through late in the day through Saturday morning. We will again have a slight chance for a shower as that Front moves through the area. Sunday and Monday should be mostly clear as High pressure rebuilds across the area. Tuesday through Friday of next week should be mild before the next series of systems looks promising for the end of November into the first week of December. This first storm of the Season looks like it will be pretty weak by the time it gets to our area, however, there is a plume of moisture just to our south that with a little luck could get caught up in the flow helping to add a little moisture to the system as it arrives locally. So keep your fingers crossed. Enjoy! That’s it for now. Thank you for joining me @ lakegregoryweather.com RC

TODAY’S WEATHER DISCUSSION AND FORECAST:


Today’s Outlook for Crestline, Twin Peaks, Lake Arrowhead and the San Bernardino Mountains.

Good Morning.
An area of Low pressure will pass through to our south today bringing more high clouds and cooler temperatures to the area. There will be a slight chance for a sprinkle today as that system passes through. Offshore flow at the surface level will continue today but at the higher elevations we are seeing a Southerly flow as we prepare for the first chance of rain for Wednesday night into Thursday morning. The first cold front of this winter season will arrive Wednesday afternoon or evening into Thursday. This system should bring from .50″-as much as an inch of rain to the local area. Snow may accompany this system for the higher elevations Thursday morning above the 6800′ level. Slow clearing will follow this storm Thursday so expect to have cool weather for Thanksgiving day. Another weaker system will follow through Friday morning with a chance for more light showers. Cool weather will last through the weekend then a slow warming trend for the first of the week.
I’m running late this morning so time to go! That’s it for now. Thank you for joining me @ lakegregoryweather.com RC
