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

Today is the last day of the rainfall year. This years total rainfall at my location was 19.57″ with 4.25″ of snow. Last year I recorded 45.90″ of rain/melted snow, and for the 2015/2016 season I recorded 32.38″ at my location. Normal is ~40.00″.
Today will be a busy day around the Crestline area as there will be a parade from Top Town to the Lake starting around 10am to kick off the days activities. Along Lake Drive there will be Venders, Bands, and lots of food with the height of the day ending with Fireworks at Lake Gregory tonight at 9:00pm.
The weather will be almost perfect as the days temperatures will be in the mid to upper 70s with clear skies and light and variable winds. Tonight at the Fireworks the temperature is expected to be in the low to mid 60s so bring a blanket and enjoy the show. Lake Arrowhead will have Fireworks on the Fourth at 9pm again with very nice weather there. Today a trough of low pressure will move out and be replaced by a slowly building High over the West coast of California. As the heights increase, so will the temperatures for the week ahead. This mornings marine layer now at the bottom of Waterman Canyon will slowly weaken and retreat toward the coast in the days ahead as the High over the area builds. As it looks today, next weekend will be very warm with daytime highs near the 100* mark in the Valley. Here we will be in the mid to upper 80s. High pressure to our East will expand West and be centered near Utah by next Friday. This will bring the hot weather to our area. As far as Monsoonal Moisture goes, currently there is nothing on the horizon for the next five days. There are a couple of Tropical Disturbances to our South, but nothing that will affect us in the near future.

Yesterday’s highs and low temperatures around the area were, Crestline-73-49, Twin Peaks-74-54, Cedar Ridge in Arrowhead-68-59, Running Springs-67-59, Big Bear-75-40, San Bernardino-89-58. Locally the skies will remain clear with a few high clouds at times. The Marine layer will stay at the lower elevations and have no affect on the local HWYS.
That’s it for today. Have a great day! RC

Average local temps for today are: 79*-53* – MAX-96*(1994)-MIN-41*(1992).
Temperatures around the area for Today and overnight:
Crestline, Twin Peaks, and Lake Arrowhead: 74-78*/52-56*
Running Springs, GVL, and Big Bear: 69-74*/42-51*
San Bernardino: 89-94*/58-64*

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

As we head into the festive weekend for Crestline, the weather will cooperate for the most part. This morning, we have fog at the lower elevations in Waterman Canyon. This will clear out later this morning. Light and variable winds becoming gusty at times today should taper off by this evening. Tomorrow for the Jamboree Days activities temperatures in Crestline will be from 73-78* during the day, and for the evening Fireworks, temperatures will be from 64-68* with light winds from the South West at 2-7mph, as it looks this morning. So bring a blanket to the Fireworks show and enjoy! Today a trough of low pressure that has brought cool temperatures to the mountains will move out tomorrow. High pressure will expand over all of SoCal over the next few days. A slow warming trend will begin Sunday, and by the end of the work week next week, temperatures are expected to be very warm especially during the weekend. Also we may see some Tropical moisture from the south move up into the Southern Deserts and possibly the Big Bear area by next weekend. This is still a long way out so I will be watching this and updating as we get closer to that time frame. To our south, there are three Tropical systems in various stages of development. One named storm Emilia currently has 60mph winds and is moving to the West. Two other systems are south of Acapulco at this time but are not very organized yet.
Yesterday’s highs and low temperatures around the area were, Crestline-77-53, Twin Peaks-78-54, Cedar Ridge in Arrowhead 76-58, Running Springs 73-56, Big Bear 77-46, San Bernardino 94-58. Locally the skies will remain clear with a few high clouds at times. The Marine layer will stay at the lower elevations and have no affect on the local HWYS.
That’s it for today. Have a great day! RC

Average local temps for today are: 79*-52* – MAX-99*(2000)-MIN-40*(1953).
Temperatures around the area for Today and overnight:
Crestline, Twin Peaks, and Lake Arrowhead: 71-76*/50-56*
Running Springs, GVL, and Big Bear: 72-76*/40-45*

TODAY’S WEATHER DISCUSSION AND FORECAST:



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

Today temperatures will begin to cool across the mountain as an area of Low pressure begins to affect the west coast. Onshore flow will strengthen over the next couple of days helped by the development of a Catalina Eddy. Fog and low clouds will slowly push Inland with greater depth possibly reaching the base of the mountain by Friday morning. Friday will also have daytime high temperatures slightly below average for this time of year. Saturday will start off with a cool morning but daytime high temperatures will begin to rebound to around 75-80* by the afternoon hours as High pressure rebuilds across SoCal. Winds through the period will be mostly from the SW at 2-8mph. We will see a period of NE winds briefly as the Low moves out and the High moves in early Saturday morning. Skies locally will remain clear through the upcoming weekend with only a few high clouds from time to time. The Fireworks on Lake Gregory are scheduled for 9pm Saturday and the weather should be good and possibly a little chilly so bring a blanket. On the long range outlook, it looks like we may see some Tropical Weather for around the 7th of July in the form of rain and or Thunderstorms locally. There are three Tropical Disturbances to our South currently. Only one has a name at this time, Emilia, and is expected to remain offshore of Mexico and not make Hurricane status. That’s it for today. Have a great day! RC

Average local temps for today are: 79*-52* – MAX-95*(1994)-MIN-37*(1996).
Temperatures around the area for Today and overnight:
Crestline, Twin Peaks, and Lake Arrowhead: 72-78*/52-56*

TODAY’S WEATHER DISCUSSION AND FORECAST:



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

Not much change today from what we had for weather yesterday. Temperatures will be in the upper 70s to low 80s across the mountain region. Winds will be light and variable becoming gusty during the afternoon hours. For Thursday through Friday night, a weak trough of low pressure will pass through to our North bringing cooler temperatures and a deeper Marine layer across all of SoCal. Gusty winds will develop as the trough passes with fog likely in the morning hours in the Valley to around the 3000′ level. Saturday a warm up will return and possibly a weak North East wind as the trough moves out of the area. Warmer more seasonal temperatures will return through the 4th of July. To our south, a couple of Tropical disturbances will continue to develop and are likely to become Hurricanes over the next few days. The moisture from these two systems look like they will stay out of the SoCal mountain and desert areas at least for the next few days. That’s it for today. Have a great day! RC

Average local temps for today are: 79*-52* – MAX-93*(1994)-MIN-33*(1996).

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

Today we will have clear skies under a ridge of high pressure. Temperatures will remain very close to what we had yesterday. Local daytime highs yesterday were, Crestline-81*, Twin Peaks-83, Cedar Ridge-78, Running Springs-77, Big Bear-83, and San Bernardino at 97*. Light and variable winds will become gusty during the later afternoon hours from 5-10mph. For today and Wednesday, no changes in the forecast locally. Thursday, a trough will develop along the west coast and move inland through the Great Basin affecting our weather through Friday. Cooler temperatures along with a deepening Marine layer that will push Inland, will help to keep temperatures below average for this time of year. At this time, Saturday looks good for the Crestline Jamboree Days Parade and Fireworks, with daytime temperatures to be around 80* and around 60-65* for the 9pm fireworks show at lake Gregory. That’s it for today. Have a great day! RC

TODAY’S WEATHER DISCUSSION AND FORECAST:



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

This morning the marine layer has stayed on the Western edge of the Inland Valley. All of the local HWYs are currently clear. An area of low pressure that brought cooler temperatures to the mountain has moved East. High pressure will again move into the West along with a warming trend through Wednesday. Local mountain temperatures will range from the upper 70s to mid 80s through Wednesday. Then another weak trough will arrive for Thursday through Saturday. This will again bring cooler weather for the end of the work week. Overall, we remain in a North West to South East flow across the U.S. that has been the pattern since mid winter. As long as this pattern remains in place, we will see weak troughs pass through the flow bringing a few days of cooler weather followed by High pressure that will bring a few days of warmer weather. As for the monsoon season, there are three potential Tropical Systems forming to the south. So the Monsoon flow may kick up next week for Arizona and South Eastern California. The long range PWAT forecast shows lots of moisture pushing North into SoCal and Arizona around the 4th to the 7th of July. We’ll see. However, this is consistent with the potential Tropical Storm development to the south. That’s it for today. Have a great day! RC

Average local temps for today are: 79*-51* – MAX-92*(1970)-MIN-35*(1991).
Temperatures around the area for Today and overnight:
Crestline, Twin Peaks, and Lake Arrowhead: 78-82*/52-58*

TODAY’S WEATHER DISCUSSION AND FORECAST:



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

This morning the FOG CAM showed low clouds and fog along the bottom of Waterman canyon. This will clear out this morning leaving hazy skies below. For the local Mountains clear skies and comfortable temperatures will be the days forecast. Onshore flow will be the norm through the week ahead with periods of gusty SW winds at times. Monday through Thursday a 500mb Sub Tropical area of High Pressure will build from 588dm to 591dm by Wednesday over the SoCal region. This will bring and increase in temperatures to the local mountains from 79-85* through the period.
However, at this time, there doesn’t appear to be any Sub Tropical moisture associated with this area of High pressure. So it will be warmer, but the air will remain fairly dry. Thursday through Saturday, cooler weather will arrive as a digging trough of Low pressure moves through the West. Temperatures will be in the 70s for that period locally. For the Crestline Jamboree Parade and Fire works on Saturday June 30th, it looks like very nice weather will be in place with daytime temps from 73-78*. As July arrives, it looks like a change in the weather patterns for SoCal will also arrive. Much warmer temperatures and possibly Monsoonal moisture as well is what it looks like at this time. The long range outlook is for a 595dm area of High Pressure to settle over the West around July 2nd along with some spin off moisture from a Tropical disturbance yet to form. To our south, Tropical Storm Daniel is making it’s way West and will not be a threat to any land areas. That’s all for today. Have a good day and enjoy the nice mountain weather. RC

Average local temps for today are: 78*-51* – MAX-92*(1981)-MIN-39*(1950).
Temperatures around the area for Today and overnight:
Crestline, Twin Peaks, and Lake Arrowhead: 75-82*/52-56*

TODAY’S WEATHER DISCUSSION AND FORECAST:



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

Yesterday turned out to be much warmer than anticipated. High temps around the area ran from 93-95* in Crestline and Lake Arrowhead, and 86-87* in Running Springs and Big Bear. San Bernardino topped out at a cool 99*. Today should be much cooler as an area of Low pressure moves through the Great Basin today increasing the onshore flow across SoCal. This morning as of 6am, light fog or haze covers the Valley to around the 2000′ level. This should not cause any traffic problems. As the system moves through the Great Basin, the Marine layer will likely thicken for tomorrow morning so I expect to see a fairly deep layer of fog along the front side of the mountain. This will give us another day of cooler weather Sunday and possibly Monday as well. Then High pressure rebuilds into the area along with warmer temperatures for Tuesday Through Thursday with daytime highs in the low to mid 80s. Mostly clear skies with light and variable winds through Monday. To our south, a couple of disturbances are taking shape. There is a chance for some of the moisture from one of these systems to eventually get caught up in the upper level flow and move into the SoCal region around the 2nd of July. Until then, the Monsoonal flow will stay away from SoCal. That’s all for today. Have a good day and enjoy the nice mountain weather. RC

Average local temps for today are: 78*-51* – MAX-92*(1954)-MIN-41*(1951).
Temperatures around the area for Today and overnight:
Crestline, Twin Peaks, and Lake Arrowhead: 76-82*/52-55*

TODAY’S WEATHER DISCUSSION AND FORECAST:



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

The first day of summer brought in warm temperatures across the mountain. Daytime highs were, Crestline-89*, Lake Arrowhead-87*, Twin Peaks and Running Springs-84, GVL-86*, and Big Bear-89. San Bernardino made it to 97*. Today’s high temperatures will be close to yesterday’s with highs today again in the upper 80s for the mountain areas and near 100* in the valley. Earlier this morning, fog moved into the IE to about the 2000′ level. This will be the case for tomorrow as well as an area of Low pressure moves through the Great Basin over the next couple of days with a trailing trough. On shore flow will increase and cooler temperatures will be the weekend forecast along with some light fog in the morning below the 2500′ level. Sunday the trough will move East and a slow warm up will return to the area for next week. Clear skies for the mountains and variable winds during the day with some gusty winds late in the day. So overall, the weather will be very nice for the weekend. To the south of off Acapulco, two Tropical systems are taking shape. At this time, neither one should affect SoCal except maybe some increase in the surf next week. On another note, I have posted some information on the possible upcoming El Nino on the ALERTS and TRENDS page of the website. I will continually update this page as more info becomes available. We are currently in a El Nino Watch due to the increase in SSTs in the Central and Eastern Pacific. Now that we are past the Spring unpredictability barrier, the forecast is for a 50-65% chance for a return to and El Nino winter for 2018/2019.
Temperatures for the Crestline, Lake Arrowhead, and Twin Peaks areas will have daytime highs today from 84-89*. Big Bear, Running Springs, and Green Valley Lake, will have daytime highs today from 80-87*, San Bernardino will see highs today from 95-100*. All areas will have clear skies with light and variable winds from 0-10 mph.
Average local temps for today are: 78*-50* – MAX-95*(1954)-MIN-43*(1951).
Temperatures around the area for Today and overnight:
Crestline, Twin Peaks, and Lake Arrowhead: 84-89*/52-59*

TODAY’S WEATHER DISCUSSION AND FORECAST:



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

Today is traditionally considered the first day of summer, also called Summer Solstice, and is the longest day and shortest night in the Northern Hemisphere.
That is as exciting as it will get for awhile. High pressure will continue to be the main weather feature for all of SoCal and the West. The 250mb and 500mb Jetstream show little change for the near term and long range outlooks. An area of low pressure will move through the Northern Great Basin over the weekend which will bring a brief reprieve in daytime high temperatures locally. But the Dominate High pressure to our South will regain strength the first part of next week with the return of very warm daytime temperatures. To our south the hurricane production has been squelched as well as along the gulf States and Eastern Seaboard. So overall we will be in a zonal flow across the southern part of the country with little change. Temperatures for the Crestline, Lake Arrowhead, and Twin Peaks areas will have daytime highs today from 84-88*. Big Bear, Running Springs, and Green Valley Lake. will have daytime highs today from 80 85*, San Bernardino will see highs today from 95-100*. All areas will have clear skies with light and variable winds from 0-10 mph. On another note, the latest El Nino forecast is out and I will be posting the highlights of that report on the www.lakegregoryweather.com/WX ALERTS/TRENDS page of the website later today along with some other interesting information. So that’s it for now. Have a great day and enjoy the first day of summer. RC
Average local temps for today are: 78*-50* – MAX-92*(1961)-MIN-36*(1995).
Temperatures around the area for Today and overnight:
Crestline, Twin Peaks, and Lake Arrowhead: 84-89*/52-59*
