A warm front will bring increasing clouds tonight and rain to the area tomorrow, mainly in the afternoon. A warmer airmass will settle in which means higher snow levels, climbing quickly through the day up to 6,000 feet by the afternoon. Shower activity will be heaviest at the coast and Cascades with scattered showers for west side valleys and isolated showers for the Klamath Basin and Siskiyou County. Most showers for the east side and northern California will arrive in the evening through the very early morning hours Saturday. Most showers that continue into Saturday will be in the Cascades and they will end by mid-morning, with any showers lingering for lower elevations will end by early morning.
After the rain ends a high pressure ridge will build back into the region, this means calm winds and quite weather which will allow inversions and valley fog to return. Depending on how quickly the fog returns and how long it lingers will really determine how warm we will be into next week. Weather models do not forecast fog well and don’t take it into account for daily warming, due to this I have dropped our high temperatures by about 5 to 8 degrees compared to guidance in anticipation of the fog. As we head into next week we’ll have a better idea of how the fog is going to form and tweak our temperatures accordingly.
Thanks for logging on and have a great evening!
