Wednesday evening forecast – Nov. 27th
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. Temperatures will stay cool throughout the week with highs well below average only in the 50s.
The first cold front has exited the area to the east leaving behind a mix of sun and clouds with a few showers, mainly near the mountains. This relative lull in activity will continue through the evening before a second front will move through later tonight through mid day Thursday. This one will have a slightly different orientation leading to a longer duration of precipitation than today.
There is a better chance of convection tonight and tomorrow. So rain rates with this next system expected to be about the same as Wednesday morning, likely peaking below thresholds but with the small chance of an isolated heavier cell spiking the rates up to an inch per hour. As with last night confidence not high enough to warrant a watch but will continue to monitor.
Snow levels and now are expected to remain low through the duration of the event. Dropping to 2,500', light snow possible over some of the higher passes in the coastal mountains including San Marcos Pass and Cuesta Grade as well as the Cuyama Valley.
Thursday's front will pass through during the early morning for SLO/SB Counties and mid morning into afternoon for Ventura County. 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.
So keep the umbrella and jackets handy for the next week as this cool and wet pattern continues.
