Milder with breezy north to east winds into Tuesday. Additional shower chances possible late Tuesday – Wednesday and again later in the week, best chances in the mountains. Snow possible in the mountains Wednesday, then again Friday and Saturday. Low confidence in snow accumulations.
Discussion
Just a few light showers remaining on radar as the mid/upper low drops south into central California this morning. Showers and thunderstorms brought heavy rain to the Sacramento region Sunday afternoon and evening as the low moved through with parts of the north and eastern metro area receiving 1.5 to 2.5 inches of rain. Much of the remainder of interior NorCal had less than 0.50 inches.
Some low clouds and patchy fog will be possible early this morning. Upstream ridging will quickly build into the region today bringing a return of dry and milder weather along with breezy northerly wind as surface pressure gradient tightens.
Highs today will be in the mid 70s to lower 80s across the valley with northerly wind gusts of 15-30 mph.
The dry weather will hold through Tuesday, then another system is forecast to drop down from the PacNW bringing a chance of showers Tuesday night into Wednesday along with cooler temperatures.
This system is forecast to give the area more of a glancing blow compared to Sunday’s, so QPF is mainly forecast over the northern Sierra and southern Cascades where 0.25″ to 0.50″ is likely. The valley may see some light showers, but only a few hundredths of an inch is forecast.
Dry weather is expected Thursday.
Extended Discussion (Friday through Monday)
Short wave trough progged to dig south through the PacNW Friday, and into the CWA Saturday. NBM showing wetter solution than deterministic models with precip chances over the forecast area Friday and mainly mountain showers Saturday.
High amplitude ridging builds inland Sunday into Monday resulting in drier weather with some gusty north to east wind.
