SHORT TERM
(Today and tonight)
Issued at 355 AM PST Wed Jan 22 2025

Upper level ridging pattern centered over coastal California will continue to amplify and build north today and tomorrow. A weak fetch of offshore flow near the surface will keep skies mostly clear with light winds today and tomorrow along with gradual warming of daytime highs, especially inland. The clear skies and light winds will allow for radiational cooling to keep overnight lows mostly below normal with another round of Freeze/Frost products likely for Wednesday morning once this mornings products expire at 9 AM PST. Highs on Wednesday will increase slightly near the coast and around 5 degrees inland from todays values.

LONG TERM
(Thursday through Tuesday)
Issued at 355 AM PST Wed Jan 22 2025

The warming of daytime highs continues on Thursday after another cold start. Portions of interior southern Monterey County may see an impressive diurnal warming from the upper 20s early Thursday morning to upper 70s in the afternoon. A disturbance over the Pacific Northwest late Thursday into Friday begins to break down the amplified ridging across the west, with an upper low eventually splitting off from the Polar Jet on Saturday, then lingering over SOCAL for the remainder of the weekend into next week. The developing upper low will definitely bring cooler daytime temperatures for the weekend through the remainder of the extended forecast. Saw no need to change the slight chance PoPs from the NBM for the weekend , as it seems to capture the weak signal for rain/snow chances (snow chances confined to elevated locations in S Monterey, San Benito Counties and East Bay Hills).
Widespread wetting rains are not expected, and locations fortunate enough to see some precip should expect less than a tenth of an inch.
