TODAY’S WEATHER DISCUSSION AND FORECAST:

Good Morning.
We will start the day today with mostly clear skies due to a transitory Ridge of High pressure over SoCal. As the Ridge moves East today, an area of Low pressure will fill in behind bringing rain to SoCal late tonight and Saturday. Saturday’s storm will have a weak AR feeding moisture into the storm helping to add to the rainfall totals locally. This will be another warm storm with a Tropical feed so the snow levels will be running from ~8000′ then slowly lowering to the 6500-7000′ level by the end of the storm Saturday night or Sunday morning. Rainfall amounts from this storm will run from 1-2+” locally with the greatest amounts along the west facing slopes due to Orographic lift. Also there will be a slight chance for a Thunderstorm Tomorrow afternoon as an area of instability moves through close to our area. Gusty winds will run from 10-30mph for this system. Fog and low clouds will arrive later today so if you are driving plan a little extra time for your travels.
Sunday, clouds will slowly clear out with a few residual showers in the morning and possible some snow showers at the higher elevations above ~6500′.Then for Monday and Tuesday, we will have mostly clear skies as zonal flow and High pressure move over the SoCal region again. Temperatures will warm up as we will see a Bright Sun in the sky.
Tuesday night and Wednesday, Another system will move across SoCal bringing rain to the area once again. This storm will be again fed by an Atmospheric River (AR) with Precipital Water (PWAT) levels reaching to around 1.25″ or a little more. This will bring rainfall totals to the area of 2.5-5.00″ of rain locally with high elevation snow levels again starting out around the 8.5k’ level then slowly lowering to around 6.5k’ by Wednesday afternoon or evening. The greatest rainfall amounts will again be along the west facing slopes due to Orographic lift there. Gusty winds will accompany this system as well with winds from 10-35mph again. Fog and clouds will also make for poor driving conditions so plan accordingly.
Overall, it looks like we will continue to have a busy weather pattern through the first part of March. As the next few storms will be warm, it does look like we will also see a few colder systems work through possibly late next week through the middle of the month.
To our North, heavy rains have brought substantial flooding to many areas. Please keep those folks in your thoughts as they have had a very difficult year.
