TODAY’S WEATHER DISCUSSION AND FORECAST:



Good Morning.
Today’s outlook for the Crestline, Lake Arrowhead, Twin Peaks, Running Springs and Big Bear areas.
Overnight in the Midwest, several Tornadoes ripped through the area leaving lots of destruction and reportedly five deaths. Today will be another rough day for the Midwest with more Tornadoes and severe weather expected there.
For the local area, today we will have a very nice day. Temperatures will be in the upper 60s to low 70s across all of the Mountain areas. All of the Wind warnings have expired. Had we been a little further into the Summer months, we would have had a RED FLAG FIRE alert for the past few days. Fortunately, we still have fairly high fuel moisture levels locally from the Winter rains so we are good for now. Today we will have variable winds becoming mostly from the SW by this afternoon. The humidity levels bottomed out in the low teens late yesterday as the NE winds tapered off. Today humidity levels have recovered to the upper 30s to low 40s. We can expect clear skies, variable light winds for the next five days through the work week ahead. Temperatures will be on the rise for all of SoCal as high pressure builds into the west coast. Locally, high temps will be in the low to mid 70s in the days ahead while in the valley, highs will be from the upper 80s to mid 90s by Tuesday and Wednesday. Fog and low clouds will develop along the coastal region and may move into the IE Monday and Tuesday mornings. On the long range outlook, there will be a chance for rain as it looks at this time for the weekend into Monday of next week. (6th-8th) A cold core low is forecast to slide down the West Coast during that time frame.
As we leave the Winter behind, dryer weather conditions will develop across the local area. However, we still have cool mornings and evenings as we begin the transition. When we have gusty NE winds, the warmth of a fire in our fireplace is inviting, but dangerous sparks can be blown into the vegetation including pine needles, and start a fire. It is a good plan to avoid using your fireplace or any other outdoor fire during windy conditions. Have a good weekend. RC

TODAY’S WEATHER DISCUSSION AND FORECAST:



Good Morning.
Today’s outlook for the Crestline, Lake Arrowhead, Twin Peaks, Running Springs and Big Bear areas.
A HIGH WIND WARNING is in effect today for strong gusty winds across the area. This will likely expire around noon today.
Gusty NE winds overnight and this morning ranged from 15-31mph at my location on the south side of Lake Gregory, 18-50mph at Playground Drive, 5-20mph at Twin Peaks, 15-22mph @ Lake Arrowhead, 12-31mph @ Running Springs and Big Bear had winds from 10-26mph. The cause of the winds is a uneven pressure gradient between Tonopah at 1022.3mb and San Diego at 1013.6mb. This will begin to change later today as High pressure now over the Pacific Ocean moves toward SoCal. As the pressure rises along the SoCal coast and Inland areas later today, the winds will slow down, then reverse by tomorrow early afternoon, becoming onshore by late afternoon across SoCal. As the SW flow returns to the area, a marine layer will develop and fog will move inland for Monday morning possibly all the way to the IE. However, temperatures will be on the rise as well. Highs today will be in the low to mid 60s for most areas with Big Bear and Running Springs remaining in the mid to upper 50s today. For Sunday, temperatures will be from 5-7* warmer than today and another +5* for Monday. The Sat/Pic from GOES 16 this morning shows clear skies across all of California and Arizona. The system that has brought high clouds and gusty NE winds to our area earlier this week, is now bringing heavy rain and severe Thunderstorms to the Midwest this morning. Up to 4″ of rain has fallen in some areas of the Midwest this morning as of 9am. For the SoCal Mountains, warm and clear weather will be the forecast for the next few days as we will be under high pressure here. On the long range outlook, there will be a chance for a cold core low to arrive here around the 6-8th of May. Rain and snow may accompany this system as it looks now. That is a long way out but not unlike early May weather. That’s it for today, enjoy the nice mountain weather.
As we leave the Winter behind, dryer weather conditions will develop across the local area. However, we still have cool mornings and evenings as we begin the transition. When we have gusty NE winds, the warmth of a fire in our fireplace is inviting, but dangerous sparks can be blown into the vegetation including pine needles, and start a fire. It is a good plan to avoid using your fireplace or any other outdoor fire during windy conditions. Have a good weekend. RC

TODAY’S WEATHER DISCUSSION AND FORECAST:



Good Morning.
Today’s outlook for the Crestline, Lake Arrowhead, Twin Peaks, Running Springs and Big Bear areas.
Today we start the day with a HIGH WIND WARNING for the San Bernardino Mountains and Inland Empire area. Strong and gusty North East winds will be likely especially for the Mountain areas through Saturday morning. Winds from 10-25mph for most areas, and from 20-45mph+ in the wind prone areas can be expected today through Saturday morning. This is due to an area of building low pressure (999mb) centered near the four corners area backing up to the Eastern side of the Sierras. Along with an area of high pressure (1028mb) over the Eastern Pacific. We are in the middle of the two pressure zones which will cause a strong NE flow across our area. Along the immediate coastal areas, a SW flow this morning will turn to offshore later today. The persistent high clouds we have had for the last few days will finally move east as the high pressure over the Pacific slowly expands over SoCal. Temperatures today will still remain a little cool with highs in the low to mid 60s. For the weekends temperatures, highs in the mid 60s can be expected with overnight lows in the upper 30s to low 40s for most areas. On the longer range outlook, starting Monday, as high pressure builds across SoCal, temperatures will be on the rise as well. For the work week ahead, temperatures will be in the 80s to 90s in the Inland areas and in the upper 70s to low 80s in the mountains.
As we leave the Winter behind, dryer weather conditions will develop across the local area. However, we still have cool mornings and evenings as we begin the transition. When we have gusty NE winds, the warmth of a fire in our fireplace is inviting, but dangerous sparks can be blown into the vegetation including pine needles, and start a fire. It is a good plan to avoid using your fireplace or any other outdoor fire during windy conditions. Have a good weekend. RC

TODAY’S WEATHER DISCUSSION AND FORECAST:



Good Morning.
Today’s outlook for the Crestline, Lake Arrowhead, Twin Peaks, Running Springs and Big Bear areas.
This morning we have light winds mostly from the NE from 3-7mph across the area. Clear skies in the mountains as well as in the Valley so far. Overall high temperatures will be about the same as yesterday’s or maybe a little cooler as we transition to a NE flow across the area later today. Other than some high level clouds, we will be mostly clear today and Friday. The North West to South East flow aloft will continue to bring areas of low pressure to our North and East. As these systems pass by, we will see alternate periods of NE winds and SW winds across the mountains. High pressure will remain anchored to our West and will expand onshore Saturday and Sunday bringing warmer temperatures to all of SoCal at that time. For today and Friday, highs will be in the mid to upper 60s for most areas. Saturday and Sunday we should be in the low to mid 70s in the mountain areas. No rain is expected for the next few days at this time. Have a good day! RC

TODAY’S WEATHER DISCUSSION AND FORECAST:


 


Good Morning.
Today’s outlook for the Crestline, Lake Arrowhead, Twin Peaks, Running Springs and Big Bear areas.
This mornings surface pressure across the West is pretty even. High pressure to our West over the Pacific will remain in place for the next several days. Meanwhile, a series of Low pressure troughs will push onshore to our North and slide down the interior to the Four Corners area then East from there. As these systems pass to our North and East, surface pressures will change, and produce periods of North East winds locally through Friday. Most of the strongest winds will be across the ridges and in the canyons with generally lighter winds across the rest of the area. A Thermal Low is appearing during the day time to our South East which will help to enhance the evening winds locally. Along the Ventura and Santa Barbara areas, Sundowner Winds will be likely as well. Periods of high level clouds will pass through over the next few days giving the sky some color. There has been and will continue to be a lot of upper level moisture around the area, so we may see some cumulus clouds develop occasionally over the next couple of days. This mornings sat pics show some development over the Grapevine area that may lead to a Thunderstorm or at least a chance for a shower there. Temperatures locally will remain in the mid to upper 60s today with slight warming tomorrow and a little cooler for Friday. The winds will be variable over the next few days but will be mostly from the NE from 5-15mph except in the wind prone areas where gusts may reach up to 25-35mph. That’s it for now, have a good day.

TODAY’S WEATHER DISCUSSION AND FORECAST:


Good Morning.
Today’s outlook for the Crestline, Lake Arrowhead, Twin Peaks, Running Springs and Big Bear areas.
This morning, low clouds and fog have moved up against the front side of the mountain below the 4500′ level. This will clear out by mid morning today. An area of High pressure to our West will expand over the area bringing in warmer temperatures and dryer air locally for the next couple of days. Low pressure currently over the Great Basin will move South East today as well, bringing rain and possible severe weather to the four corners area later today and Wednesday. The WIND ADVISORY has expired for SoCal as of this morning so for today and Wednesday, look for variable winds with a few gusts from 5-10 mph. High clouds will give accent to the sky as they pass over and that’s about it for today. High temperatures today for Crestline/ Arrowhead areas will be in the upper 50s to low 60s. Big Bear and Running Springs will see temperatures in the mid to upper 50s today. Overnight lows should remain in the upper 30s to low 40s across the whole area. That’s it for today. Enjoy the nice Mountain Weather. RC.

TODAY’S WEATHER DISCUSSION AND FORECAST:


Good Morning.
Today’s Forecast will be for Sunday and Monday as I will away tomorrow. For today, a trough of low pressure will pass North of SoCal today. This will bring in much cooler temperatures for today and Monday in the Mountains as well as in the Valley by 10-15*. South West flow will develop across the area along with an increase in the Marine layer. Tomorrow morning we may see fog and low clouds reaching into the Valleys and up against the mountain slopes of the front country. High temps tomorrow will be cool running in the mid 60s for most areas, about the same as today for the days highs. Tuesday morning the Marine layer may move back into the Valley before a change in wind direction takes hold. NE flow will follow the departing trough on Tuesday with warmer temperatures again for the middle of the work week. Late in the week, another cooling trend will develop across all of SoCal as another trough passes to our North. That’s it for today. Have a good weekend I hope to return soon and update the weeks forecasts. RC

TODAY’S WEATHER DISCUSSION AND FORECAST:


Good Morning.
This mornings Forecast for the Crestline, Lake Arrowhead and surrounding Communities.
It will be pretty hard to beat the weather we had yesterday, but today may be even nicer. Temperatures across the mountain yesterday were in the 70s everywhere with light and variable winds making for a beautiful day. Today, temperatures will be about the same and maybe slightly warmer with highs again in the low to mid 70s for all areas. Cirrus clouds will give the skies some character today and may help to keep temperatures in check. Highs in the Valley yesterday ran from the low to mid 90s with a report of 100* in Moreno Valley. Today will be about the same for the Valley regions. Tomorrow, onshore flow will return to SoCal bringing in a cooling trend that will bring temperatures down from 8-10* for all areas. A trough of low pressure will pass North of our area tomorrow to help with the cooling trend. An area of High pressure directly to our West, will keep the Polar Jet stream North of SoCal, and keep the Sub Tropical Jet stream south of the area as well. For Monday and Tuesday, high temperatures locally will be in the upper 60s while the valleys will be in the mid 80s. Morning fog and low clouds will push onshore possibly reaching into the Valley below by Monday morning. As we transition to a more Summer like pattern across SoCal, we will see a series of weaker systems passing to our north with little effect on our weather here in SoCal other than increasing onshore flow with morning fog and low clouds, followed by offshore winds and warmer temperatures. We still have a chance to see more rain although once Mothers Day has passed the likelihood is greatly reduced. On another note, there is a lot of talk of the return of El Nino for the Summer and Fall ahead. If that does develop, we could see some Summer rains locally once the Monsoon Season gets fired up. As of now, we are slightly above what would be considered “normal” for the current rainfall year. I have received 41.53″ so far and a normal year is about 40.00″ for my area. Have a good weekend and enjoy the nice Mountain weather. RC

TODAY’S WEATHER DISCUSSION AND FORECAST:


Good Morning.
Gusty North East winds this morning in the Waterman Canyon and across HWY 330 from 15-30mph can be expected. Be ADVISED, if you are traveling down the hill. The main weather feature for the next few days will be an area of High pressure to our West. As High pressure develops across all of the Southern half of California, temperatures will be on the rise as well. Today for the mountain areas temperatures will be in the low to mid 70s below the 6000′ level and in the mid to upper 60s above 6000′. In the Valley below, temperatures will be very warm with highs expected to reach into the low 90s today, and even warmer Saturday by a few degrees. Sunday, temperatures will cool down by around 7-10* in the valley areas with high temps in the mid 80s down the hill, and in the upper 60s to low 70s for the mountain areas. Clear skies with light and variable winds through the period is about all the change we will see. At this time, no rain is in the foreseeable future for SoCal. Have a good day and enjoy the great mountain weather. RC
