Area Forecast Discussion National Weather Service Sacramento CA 343 AM PDT Sat Sep 25 2021


SYNOPSIS. A cooling trend through early next week with shower chances late Monday into Tuesday, especially over the mountains. Breezy mountain winds possible during the afternoon hours through Monday.

DISCUSSION.

Upper ridge that has brought the warm weather this past week will flatten today, as troughs begin to impact the Pacific Northwest. This will initiate a Delta breeze with a cooling trend over the weekend. Afternoon high temperatures today will fall into the upper 80's to low 90's, which is about a 10 degree cool down from the past few days. Larger trough will deepen along the West Coast Monday with showers spreading over the Coast Range through the day. Showers will then spread over much of the Northern Sacramento Valley and Sierra Monday night. Precipitation amounts look to be on the light side with Valley amounts generally less than 0.25 and mountain amounts less than 0.50 inches. Further cooling into the 80's Sunday and Monday then 70's Tuesday with increasing onshore flow. Winds through the Delta could gust up to 35 mph at times into next week.

Brief periods of breezy ridgetop winds will be possible during the afternoon hours through Monday ahead of the trough. This could bring elevated fire weather conditions for a few hours, but increasing relative humidity levels each day will diminish the concern.

EXTENDED DISCUSSION (Wednesday THROUGH Saturday).

Models similar in EPAC upper ridge building inland over NorCal Wednesday behind exiting system. Ridge axis shifts through Wednesday night into Thursday as next Pacific frontal system approaches. Front weakens as it moves into the PacNW Thursday and associated precip remains north of our CWA. Associated upper trough follows Friday. Oper GFS closes trough off the CA coast while EC and ensembles support a more progressive and drier solution. Below normal high temperatures expected through the extended forecast period.
