KEY MESSAGES
- Dry and mild weather continues into the early week ahead.
- An atmospheric river storm system mid to late week will bring widespread precipitation, gusty winds, cooler temperatures, and mountain snow.
DISCUSSION
Today through Tuesday
Dry and mild weather will continue through the remainder of today through Tuesday, with temperatures above normal. High temperatures will range from the upper 60s to lower 70s in the mountains to the upper 70s within the Valley. Lowest RH values will be in the Sierra along and south of I-80 through Tuesday.
HRRR and HRRR continue to show patchy dense fog developing Monday morning before sunrise and lasting through the late morning.
Confidence remains low on exact location and how dense the fog becomes. Right now, best chances are in the southern Sacramento Valley and the northern San Joaquin Valley Monday morning.
Wednesday and Onward
Ensembles are in good agreement on the ridge over western CONUS broadening out and shifting eastward mid to late week, with a deepening trough in the eastern Pacific. Abundant moisture flow into the southwestern United States and synoptic forcing will aid in the development of widespread rain and mountain snow. Breezy winds and cooler temperatures will accompany this system Wednesday through the end of the work week. Best chances for thunderstorms will be on Thursday before the system moves further inland by Friday. Mountain snow chances will be 8500 feet and higher Thursday, but decrease as we move into Friday toward 5500-6000 feet and above. Thunderstorm chances shift toward rain showers on Friday as the instability shifts with the system eastward. Looking ahead to next weekend and beyond, guidance has hinted at our active pattern continuing with the potential for another system. Details remain highly uncertain at this time.
AVIATION
VFR conditions prevail through the rest of today and into tonight. Light and variable winds through the period, with the potential for patchy dense fog 10z through 17z within the Sacramento area into Stockton. Confidence remains low on the patchy dense fog and its exact location and timing. Otherwise, a FEW to SCT clouds will move through the northern Sacramento Valley this afternoon and evening, with FEW sky coverage tomorrow.
STO WATCHES/WARNINGS/ADVISORIES
None.
