Showers thru Thanksgiving and next week has even more rain potential

Posted at 5:51 PM, Nov 27, 2019

The low pressure system in the area will keep chances of rain and mountain snow in the area through tonight and Thanksgiving day. Precipitation will diminish from north to south across the region Thursday night into Friday, but another storm system is expected to impact San Luis Obispo and Santa Barbara Counties Saturday night.

The first cold front has exited the area to the east leaving behind a mix of s showers, mainly near the mountains. A second front will move through later tonight through mid day Thursday. This system has a slightly better chance of producing a few more isolated thunderstorms which can produce hail and cold air funnels and waterspouts.

Rain rates with this next system expected to be about the same as today, likely peaking below thresholds but with the small chance of an isolated heavier cell spiking the rates up to an inch per hour.

There was a little snow over the Grapevine this morning but expecting more later tonight into Thursday as snow levels drop to 2500-3000`. Light snow is possible over some of the higher passes in the coastal mountains including San Marcos Pass and Cuesta Grade as well as the and Cuyama Valley.

Thursday`s front will pass through during the early morning for SLO/SB Counties and mid morning into afternoon. Followed by scattered showers that will taper off overnight into Friday morning. Minimal if any shower activity expected Friday, but temps remaining quite cool with lower elevation highs still in the 50s.

Dry but cold Friday night into Saturday morning before another system starts to spread moisture across western SLO/SB Counties.

Next week has to be watched in case an atmospheric river situation develops, models are showing a lot of SW moisture supply. Right now the exact position of the stream can't be projected with high confidence but if it were to develop over us several wet events are possible. Stay tuned.
