February 4, 2021 – Dry weather with mild daytime temperatures and cool nights will continue into the middle of next week. Occasionally breezy north to east winds the next several days.
Discussion
Other than a thin strip of fog developing along the eastern edge of the northern San Joaquin Valley, skies are clear across interior NorCal early this morning. North surface pressure gradient has steadily increased since Wednesday evening (MFR-SAC now over 7 mbs), and northerly breezes have spread southward through the Central Valley with local gusts in the mid teens to mid 20s mph currently being observed along the western edge of the valley.
Northwest flow pattern expected to hold over NorCal through the weekend providing dry weather with unseasonably mild days (highs around 5-10 degrees above average) and cool nights. Breezy north to east winds forecast to peak today with lighter north winds continuing the next few days.
Extended discussion (Monday through Thursday)
Ensembles indicate dry northwest flow prevailing across the region early next week. The exception could be some light precipitation over the mountains by mid-week.
Ensembles generally support ridging over the Eastern Pacific, with dry and mild conditions throughout the region. However, weak impulses might bring some light precipitation late next week. Forecast highs will be in the low 60s in the Valley, and upper 30s to mid 50s over the mountains.
