TODAY’S WEATHER DISCUSSION AND FORECAST:



Today’s Forecast for Crestline, Twin Peaks, Lake Arrowhead and the San Bernardino Mountains:
Good Morning.

This morning at round 5am, thick fog blanketed the area from Rim Forest on HWY 18 to lower Waterman canyon. Since then, the thick Fog has backed off some to around the Crestline bridge as of 7am. The Lake Gregory/HWY 18 webcam now shows light fog. A trough will pass through in a couple hours, around noon. Once that passes, the Marine layer will retreat toward the Coast with less morning fog in the local IE area through the weekend. We will be on the Northern tip of a Sub Tropical Jet that will help to bring in much warmer temperatures beginning tomorrow. By Sunday and Monday, Summer will be in full swing with temperatures in the mid to upper 80s locally. The Valley will see highs in from 90* to 95* or higher for the same time frame. Friday morning, a wind change to the NNE will help to dry the air mass also helping temperatures to soar. At the upper levels, an upper level area of Low pressure will develop to our South late Friday. Then it will move Inland across Baja CA, moving up into Arizona by Sunday. This will help the air flow to turn from the North, to the North East, for Friday and Saturday. Sunday looks like the warmest day locally. Then by Sunday afternoon, the wind flow will return to the South West. That will help to bring a cooling trend to the local area beginning Monday.
That’s it for today. Thanks for joining me @ lakegregoryweather.com

TODAY’S WEATHER DISCUSSION AND FORECAST:



Today’s Forecast for Crestline, Twin Peaks, Lake Arrowhead and the San Bernardino Mountains:
Good Morning.

Fog has returned to the IE this morning. Currently as of 5am, the depth of the fog layer is from the ~2000′-4000′ level. So plan a little extra time if you are driving down the hill this morning. Across the area above the ~4500′ level, clear skies can be expected for the morning. The marine layer has deepened overnight due to a Catalina Eddy that has developed just offshore as well as a weak trough of Low pressure that will pass through by tomorrow evening. So expect to have another foggy commute Thursday morning with a little deeper Marine layer. Temperatures will be much cooler today and Thursday with highs expected to be in the mid to upper 60s today, and in the upper 50s to low 60s, Thursday. Overnight lows will dip into the mid 40s for the Crestline and Lake Arrowhead areas, and for the Big Bear, Running Springs, and the surrounding area there, overnight lows will be in the upper 30s to low 40s. Skies above the 5500′ level will remain mostly clear today. Gusty winds can be expected across the area beginning later this afternoon as a surface pressure gradient of 10mbs plus, develops from the San Diego area to the Desert. Friday and for the weekend, a big warm up will bring in temperatures to the 70s and low 80s by Sunday. This pattern of transitory Highs and Lows will continue to bring a variety of weather to all of SoCal through the next week. Fog and low clouds will move into the IE for a couple days then retreat back to the Coast. Then return as another weak Low pressure system moves through the flow. No measureable rain is expected for the next seven days. Yesterday there was a weak chance for Thunderstorms but only high based clouds developed with no reports of storm activity locally.
That’s it for today. Thanks for joining me @ lakegregoryweather.com

Today’s Forecast for Crestline, Twin Peaks, Lake Arrowhead and the San Bernardino Mountains:
Good Morning.

Yesterday we had a very nice day around the mountain with temperatures in the upper 70s to low 80s. Today will be much the same temperature wise with the addition of a few high clouds and a slight chance for a Thunderstorm. A weak meso low to our immediate southwest, of off San Diego, will bring a high based cloud layer over SoCal today. Thunderstorm parameters are very weak but there will be a chance. This will move out quickly tonight as an area of Low pressure moves into the Great Basin. Overnight, the Marine layer will deepen, and return to the area with Fog to the ~3500′ level for tomorrow morning. Temperature for Wednesday and Thursday will be much cooler with highs both days in the low to mid 60s. Currently as of 5am, there is no fog on the local HWYs. Winds today will be light and variable becoming South West later today as Low pressure moves into the Great Basin. Late tonight, and tomorrow, we could see some fairly strong gusty winds as the pressure gradient between San Diego and the Great Basin increases to around 10mbs. That’s it for today.

Today’s Forecast for Crestline, Twin Peaks, Lake Arrowhead and the San Bernardino Mountains:
Good Morning.

Memorial Day. A day in which we remember those before us that helped make this country what it is. Some who gave the ultimate sacrifice.
Clear skies and warmer temperatures will be the forecast for the next few days. Low pressure over the Great Basin that has kept us cool over the last several days will weaken and move East beginning later today. This will pave the way for a Ridge of High pressure to temporarily build over the SoCal region. NE flow across the area for the next few days will help to push the Marine layer back toward the Coast through Wednesday. Temperatures will warm into the mid to upper 70s today, with additional warming Tuesday of around 5* locally. Wednesday, temperatures will begin to cool as another area of Low pressure, along with the South West flow, returns to SoCal. Thursday will be considerably cooler as the Marine layer will move back into the IE with fog expected to the ~4500′ during the morning hours. This pattern, of weak areas of Low pressure, alternating with weak Ridging, is typical for SoCal this time of year. This is partly why we have may gray or June gloom. Have a good day today, and remember those who have served in the various forms of the Military over the years that have helped to keep America safe. Thank you. RC

Today’s Forecast for Crestline, Twin Peaks, Lake Arrowhead and the San Bernardino Mountains:
Good Morning.

The Marine Layer has backed off this morning to the 3500′ level, but will slowly creep up higher, before clearing out by noon today. Check the webcam page for live viewing from the six webcams located across the mountain. All of the mountain recreational areas are above the Marine layer currently, as of 8am. The area of Low pressure that has brought cool weather and a deep Marine Layer to the area is slowly moving East today. Currently centered over Utah, Wyoming, and Colorado. We are on the back side of the circulation giving us a North East flow this morning. This flow will continue to develop today helping to push the Marine layer toward the Coast, except for the early morning hours. A Catalina Eddy over immediate Coast, will keep the fog near the Coast with cool temperatures there. For the Inland areas, a nice warm up will begin today lasting through Tuesday when temperatures will peak for the Inland areas. Locally, temperatures will be in the upper 60s today, low 70s tomorrow, and the mid 70s and possibly into the low 80s in some of the warmer areas Tuesday. For the Valley, temperatures will range from the upper 70s to low 80s today, to the upper 80s to low 90s by Tuesday. Overnight lows will cool off to the mid to upper 40s locally. Clear skies and afternoon gusty NE winds will be the forecast for the next few days. The Marine layer will push toward the Inland Valleys during the early morning hours, but it should be less dense, and clear out by 10am, except for the Coastal Region. On the longer range outlook, another trough of Low pressure will arrive in SoCal next Thursday bringing a return of Low clouds and fog. No measureable rain is in the 5-Day forecast. On another note, the Gulf Coast is bracing for the first Tropical Storm of the Season. Strong winds, heavy Rain, Possible Tornadoes, and flooding, from Alabama to Florida, will put a damper on their Memorial Day weekend there. That’s it for today.

Today’s Forecast for Crestline, Twin Peaks, Lake Arrowhead and the San Bernardino Mountains:
Good Morning.

Once again, Fog, Drizzle, and light rain will be the main weather feature today. This morning, Fog has moved into the local area with reduced visibility and wet roads in some areas, especially along the Rim. Plan extra time if you are traveling around the area. Another weak atmospheric wave is pushing through SoCal at this time. Fog, low clouds and drizzle can be expected below the 5500′ level this morning down to the 2000′ elevation. Some clearing will begin later this morning especially away from the Rim area. This afternoon, gusty winds from the South West will be likely along the ridges and canyons as the trough moves through. Temperatures today will again be in the mid 50s to low 60s for most of the local area. Tomorrow, a ridge of High pressure will begin to develop over the West coast of SoCal. Morning fog, and low clouds will move into the IE but should be lower in elevation and clear out by mid morning. As the area of low pressure moves East, we will pick up a period of North East winds during the middle part of the day. Then we will return to an onshore flow for Monday under a Ridge of High Pressure. This will prompt a warming trend that will last through most of the work week ahead. Temperatures will climb into the upper 60s to low 70s Sunday. Temperatures will continue to climb Monday, and will be close to 80* by Tuesday, for the local area. Thursday, another trough will pass through with a return of cooler weather along with the return of more foggy conditions for SoCal. In the Gulf region, the first named storm of the Tropical Summer Storm Series will arrive as Alberto, sometime Monday. Alberto will affect all areas from Alabama to Florida with heavy rain, Thunder Storms and Tropical Force winds. That’s it for today. Have a good weekend. More Tomorrow morning. RC

Good Morning.

More Fog this morning along the Rim will make for more driving issues. Slow down and turn on your headlights! Currently the fog is running from the ~2000′ level to ~5500′.
An area of Low pressure @ 563mbs is moving onshore currently, and is centered near the San Francisco Bay area. This Low will track from the South West toward the North East, and will move into Utah by Monday morning @ around 565mbs. As this area of Low pressure moves slowly Inland, locally, we will see a couple of weak waves of energy move through the SoCal region. The first has just moved through bringing Fog, and a couple hundredths of an inch of moisture with it. This wave will move out and we should see slow clearing over the area by later this morning. The next wave will move through tonight bringing more low clouds and fog to the area with drizzle and may be a little more moisture as well. The surface pressure across the area is, Tonopah @1010.3mbs and San Diego @1019.4mbs. This will keep us in and onshore flow through Saturday night. As the Low moves East late Saturday night or early Sunday morning, we will be on the backside of the system picking up a wind change to the North East. Along with the wind change, a quick warm up will begin. Temperatures will go from the low to mid 50s today and Saturday, to the mid 70s and possibly 80* by Monday in some of the warmer areas. So the Holiday weekend will be filled with changing weather. In the Gulf region, the first named storm of the Tropical Summer Storm Series will arrive as Alberto, sometime Monday. Alberto will affect all areas from Alabama to Florida with heavy rain, Thunder Storms and Tropical Force winds. That’s it for today. Have a good weekend. More Tomorrow morning. RC

Good Morning.

For today, fog will continue to shroud the Rim areas from around 1k’-4500′. Temperatures will be close to yesterdays with highs from the mid 60s to low 70s. The marine layer is running about 3500′ thick currently, (5am) so be sure to plan accordingly in you are headed down the hill on the local Hwys. A Cut Off Low at 570mbs will move onshore affecting all of SoCal for the next few days. This Low will remain fairly stationary over the Central California region through Saturday night. Cooler temperatures and a deeper Marine layer will bring drizzle and a slight chance for light sprinkles in the mornings through Saturday, for the Valley, and Coastal Mountain areas. The Low will move out of the area on Sunday. Temperatures will warm up quite a bit for Monday and Tuesday along with North East winds for a period, as the back side of the departing Low moves through. Away from the Rim, temperatures will be seasonal with gusty winds at times. Mostly clear skies above the 5500′ level can be expected locally. RC

Today’s Forecast for Crestline, Twin Peaks, Lake Arrowhead and the San Bernardino Mountains:
Good Morning.

This morning we still have fog and clouds along the Rim to around the 5000′ level. The webcam at Playground Drive W/St is fogged in. However, at 18 and Lake Gregory, its clear as of 4:30am.
As you travel away for the Rim, Northerly, it’s mostly clear at this time. So if you are driving down the hill, expect to have another foggy drive this morning. The Marine layer has been persistent over the last week or so, this is mostly due to a Catalina Eddy helping to push the Marine Layer Inland, as well as the areas of Low pressure that are typical for this time of year helping to maintain a strong onshore flow. The onshore flow brings moist cool air in from over the Ocean, Inland. As the surface temperature of the land mass heats and cools, fog can form to varying depths from a few hundred feet thick along the Coast, to 5500′ thick, reaching Inland to the local area. Several other factors come into play also such as, wind speed and flow, daytime heating, and Geographical barriers, which all play a part in the local daily weather. Yesterday, temperatures across the local area varied quite a bit. Valley of the Moon, had clear skies and a high of 76*, while along the Rim on Skyland Drive had only 53* for the days high temperature due to the thick Marine layer. Big Bear had clear skies and highs around 66* as they were above the Marine layer’s influence. So as you can see, the local area has many different microclimates. Today, temperatures will be a little warmer as we transition to a weak Ridge for today and Thursday. We should see a more shallow Marine layer as well. However, Friday and for the weekend, our weather will be influenced by another Cut Off Low that will move over the Central part of the State. This will bring a return of a deeper Marine Layer, and cooler temperatures through Sunday.

Temperatures around the area for Today and overnight:
Crestline, Twin Peaks, and Lake Arrowhead: 60-67*/42-48*

Good Morning.

Yesterday, Fog and clouds shrouded the area with some light precipitation reported as well. Today, will be about the same as an area of Low pressure now centered over California and Nevada remains in place. Currently as of 5am, we have Fog from Rim Forest to San Bernardino. If you are headed down the hill, use your headlights even during the day, and plan some extra drive time. The further North you are from the Rim, the more clearing you will see today. A few light showers or mainly drizzle will keep the roads wet especially along the Rim today. No measureable moisture is expected. The area of Low pressure currently over our area will slowly depart to the Northeast later today and this evening. This will give us a little warmer weather and clearing skies for tomorrow. The Marine layer will still be up against the Coastal slopes locally at or about the 3500-4000′ level in the morning hours. We will be under a weak Ridge for a couple days before the next trough arrives Friday. This trough is expected to stay a little further North, but we will still see morning fog and low clouds as the Marine layer deepens, along with temperatures in the mid 50s to low 60s for the weekend.
