Mostly cloudy skies remain across the region early this morning as the deep closed low to our southwest drops southward west of 30N/130W. Radar also indicates some very light precipitation to the north of Sacramento along a weakening area of deformation. Current temperatures range from the 30s in the mountains, to the mid 40s to lower 50s across the Central Valley.

Precipitation chances will diminish greatly by later this morning and this afternoon as the offshore lows continues moving south. A few showers will linger across the mountains into this evening. Low precipitation chances may return to areas south of Sacramento on Tuesday and Wednesday as the system moves east into SoCal.

Warmer temperatures will return to the region today, and will once again be well above average beginning Tuesday as ridging and northerly surface flow develop.

Extended discussion (Friday through Monday)

Dry weather Friday as short wave upper ridging moves through. System then drops out of the north over the weekend bringing a widespread threat of precipitation, best chances on Sunday. Models differ with strength and timing which leads to lower confidence in the forecast attm. Disturbance looks to push south of the CWA Monday with decreasing POPs over interior NorCal.
