TODAY’S WEATHER DISCUSSION AND FORECAST:

..Good Morning.
..A beautiful weekend is on the rise!
..High pressure aloft over the Montana and Wyoming region will bring an offshore flow across all of SoCal today, and tomorrow morning. This will bring warmer temperatures to all of the SoCal region including the local mountains. Temps in the 50s will be likely for most of the mountain areas today and Sunday. The valley will see daytime highs in the low to mid 70s! High clouds will be passing over to make for nice sunsets.
..Monday, a weak Trough will move over the West Coast bringing and increase in clouds and a slight chance for a shower through Tuesday afternoon. Temperatures will cool back down to more normal daytime highs for this time of year. We will have Gusty onshore winds with the possibility of Ridge Fog for Monday night and Tuesday morning.
..Wednesday will be a transitional day as a Subtropical Ridge of High pressure develops across the Southwest. This will bring in another warming trend through the weekend.
..For the longer range “Crystal Ball” outlook, we may see a pattern change toward the end of the month. This mornings updates show a chance for a decent system for our area around the 28th.
..Have a good day today and enjoy the ever changing mountain weather.
..That’s it for today. Have a good day and thanks for joining me at lakegregoryweather.com.

TODAY’S WEATHER DISCUSSION AND FORECAST:

..Good Morning.
..Low clouds and fog are hanging around this morning after out overnight rain and snow in some areas. Rainfall totals are running from .31-.88″ across the area with Snowfall amounts generally running about 1-2″s.
..Today we will have slowly clearing skies as High pressure builds in across all of SoCal. Temperatures will warm up tomorrow and Sunday before cooling again Monday.
..High clouds will continue to flow across the region throughout the weekend but we should see generally nice weekend weather here.
..Saturday morning gusty winds will be possible especially in the Canyons and Passes due to Surface High pressure in the Great Basin building then moving East Sunday.
..Another Trough will move onshore in the PAC-NW Monday and we will see the trailing end with only a slight chance for precipitation locally. The general pattern looks like West Coast Troughing will continue through the rest of the month.
..Most if not all of these Troughs will stay to far North to bring much more than clouds and an occasional slight chance for a shower locally over the next five days.
..Looking into the “Crystal Ball”, it’s looking like mostly clear weather through the end of January. There are a couple of possibilities for precipitation but that is a long shot.
..Have a good day today and enjoy the ever changing mountain weather.
..That’s it for today. Have a good day and thanks for joining me at lakegregoryweather.com.

TODAY’S WEATHER DISCUSSION AND FORECAST:

..Good Morning.
..This morning we have mostly clear skies with light South West winds running from 5-8mph.
..An area of Low pressure is moving South along the Coast this morning bringing rain and snow at the higher elevations, and to most of the PAC-NW. As this system moves South today, rain will spread South as well to most of SoCal by this evening.
..Rain, with higher elevation snow can be expected to begin between 6-8pm tonight. Ridge Fog will begin to develop by around 4-5pm today lasting through early tomorrow morning. This storm will move through quickly, weakening as it does. Preliminary rainfall totals are running around .50-.75″ for the mountains with the snow level beginning at around the 5500′ level, then lowering to the 4500-5000′ level by early tomorrow morning. The South West facing slopes will see the greatest amount of Rainfall due to Orographic lift from the South West flow. As this system works it’s way through the area, rainfall totals will diminish as it moves South.
..As for snowfall amounts, Running Springs, Arrowbear, and Big Bear could receive from 2-4″ of snow from this storm. As the freezing level lowers, snow could fall as low as the 4500′ level with only a trace of snow accumulation at that elevation. Most, if not all of the snow accumulations will be above the 5300′ level. Below that elevation will just be wet snow showers and rain.
..Winds will be strong late this afternoon as the gust front moves through around 4-6pm. Gusts from 15-35mph can be expected tonight with the possibility of higher gusts to 50mph along the Ridges and in the normal wind prone areas through the night tapering off tomorrow by mid morning.
..All of this will clear out by mid morning tomorrow as High pressure is right on the heels of this system. The weekend will be warmer with mostly clear skies through Monday.
..A weak system will pass through Monday but at this time, that system looks dry for our area.
..The next system that may bring rain or snow to the area will arrive around the 20th of January.
..Have a good day today and enjoy the ever changing mountain weather.
..That’s it for today. Have a good day and thanks for joining me at lakegregoryweather.com.

TODAY’S WEATHER DISCUSSION AND FORECAST:

..Good Morning.
..Today we will have a few high based clouds passing over with light and variable winds. Rain and snow is falling to our North from a deep area of Low pressure that is intensifying this morning, far to our North.
..As this system moves onshore, most of the energy will stay from Central California and North from there. Here we will be at the bottom of the Trough as it moves through the PAC-NW.
..Rain will fall late Thursday afternoon as the Trough axis moves through around 4pm. Gusty winds will accompany this passing with gusty SW winds from 15-35mph locally. Higher gusts can be expected in the normal wind prone areas up to 50mph. As the Center of this area of Low pressure moves Inland Thursday night, there will be an onshore pressure gradient of ~-10-14mbs to the Desert. This will bring strong and gusty winds downslope winds to the lee side of the San Bernardino Mountains. The Desert areas such as Johnson Valley, Antelope Valley and Victorville etc, will all have a period of strong and gusty winds through mid morning Friday. A WIND ADVISORY will be likely for those areas. Locally, a WINTER WEATHER ADVISORY will go into effect at 6pm Thursday ending at 2am Friday morning for the possibility of snow, icy roads, and gusty winds.
..As of this morning, the Freezing levels will be around the 5500′ level which means we could see snow to the ~4800′ level. Rainfall estimates are running from .35-1.00″ with the greatest amounts on the SW facing slopes due to Orographic lift there. Snow accumulations of 1-2″ will be possible from 4800-5300′ level. Above that, from 2-5″ will be possible with the greatest amounts at the higher elevation above 6200′. Above the 7000′ level 4-6″ of snow will be possible.
..Friday morning this will all clear out as a Ridge of High pressure returns to the SoCal area. Daytime temperatures will be slow to warm but the weekend should be pretty nice for our mountain region. Saturday and Sunday will be sunny and warmer with light and variable winds and mostly clear skies.
..Looking out at the Crystal Ball outlook, the next possible system to bring rain and or snow to the area, will be around the 20th as it looks this morning.
..Have a good day today and enjoy the ever changing mountain weather.
..That’s it for today. Have a good day and thanks for joining me at lakegregoryweather.com.

TODAY’S WEATHER DISCUSSION AND FORECAST:

..Good Morning.
..So far there is no Fog in the Valley, or along the local Ridges. Today we will have mostly clear skies with only a few high clouds later today.
..There is a weather change coming that will begin to affect the local area by tomorrow afternoon. An area of Low pressure will begin to develop off of Washington State late tonight. This will become a Long Wave Trough along much of the West Coast by tomorrow night stretching from the Gulf of Alaska to SoCal. Rain and snow will spread South as the Front moves onshore in the PAC-NW. As the system moves inland, it will spread South toward SoCal weakening as it does. The brunt of this storm will affect Central California, and North from there. Here in SoCal, we will get the weaker bottom end of the Trough with only a short duration rain event here.
..Rain and or snow will begin locally during the afternoon hours on Thursday. The snow levels will begin around the 6000′ level, then lower to ~4500′ by Friday morning. At that time most if not all of the moisture will have moved through leaving only scattered showers or snow showers for early Friday morning. Gusty winds will accompany this system beginning Wednesday night, lasting through Friday morning. Accumulations of snow for the areas above the 5500′ level will be from 1-4″. From the 4000-5000′ levels, rain and a trace of snow up to 1 inch can be expected.
..Looking out at the long range models, the MJO is forecast to be fairly strong in phase 6, moving into phase 7 later next week. This could mean High pressure over the Eastern Pacific through the next seven days. Then as we transition into phase 7 if the MJO stays strong, we could see a change to a wetter Pineapple Express type pattern to finish out the month. This will be interesting to watch over the next week to see how the MJO Forecast plays out.
..That’s it for today. Have a good day and thanks for joining me at lakegregoryweather.com.</strong>
