TODAY’S WEATHER DISCUSSION AND FORECAST:
Today’s Forecast for Crestline, Lake Arrowhead and the San Bernardino Mountains.
Today we will have foggy or cloudy weather below the 6200′ level for most if not all of the day. The cloud layer is running from 2200′ to around 6000′ this morning and doesn’t look like it will clear out at all today. So if you are traveling on the local HWYs, plan a little extra time and don’t forget to use your headlights. An area of Low pressure in the upper atmosphere will remain over SoCal through late Thursday. This will keep the fog and low clouds around until then. Friday, weak high pressure will quickly build into SoCal and move out just as quickly Saturday in advance of a deep trough to arrive in SoCal Saturday afternoon or evening. This mornings charts look a little different than what they showed yesterday in that it now looks like most of the trough will stay just to our north around Ventura or Santa Barbara. However, a plume of moisture riding on the Sub Tropical Jet (STJ), will be very close to our area and may feed moisture into the bottom of the trough of low pressure Sunday/ Monday. So it now looks like we will have warmer temperatures for the approaching system which will keep the freezing or snow level higher than originally thought, around 9000’~. The other change is, moisture content. Depending on where the STJ ends up, we could see more or less rain. At this time, it looks like for the local mountains we could see anywhere from .50-1.00″ of rain to just a drizzle. I will of course be updating this estimate as we get closer to that time frame. Daytime temperatures for the Mountain areas will run from the low to mid 50s for Crestline and Lake Arrowhead along the Rim. For the North side of Arrowhead, Deer Lodge Park etc, today’s highs will be in the low to mid 60s with partial clearing there. For Running Springs, Green Valley Lake, and Big Bear partly cloudy to clear skies will bring warmer temperatures with highs today in the upper 50s to low 60s. Overnight lows will be in the low 40s to low 50s across the area except Big Bear where overnight lows will be in the upper 20s to low 30s. All areas will have light and variable winds today and tonight from the SSW. Have a safe and fun Halloween. *RC. Thank You for joining me @ www.lakegregoryweather.com
