Area Forecast Discussion National Weather Service Sacramento CA 156 PM PDT Sun Sep 19 2021

SYNOPSIS. Dry and warmer weather this week. Gusty north to east winds late tonight through Tuesday morning will bring periods of critical fire weather to much of the area. Breezy offshore winds may return on Thursday.

DISCUSSION. Visible satellite shows scattered, low-level cloud cover across much of interior NorCal this afternoon. Radar returns have diminished and no further precipitation is expected as this trough continues to move east and out of the area. Total rainfall amounts varied mostly by elevation, with the mountains and foothills the big winners for this event receiving anywhere from a tenth up to an inch (locally higher). In the Valley, much less precipitation was seen with amounts anywhere from zero to a couple hundredths of an inch.

EPAC upper ridge builds inland tonight into Monday as surface high builds through Oregon into the Great Basin. This will bring back gusty north to east winds across much of the area late tonight through Tuesday morning. The strongest winds are expected across the western portion of the Sacramento Valley, Coastal Range, and mountains north of I-80 tomorrow morning, decreasing slightly by Monday evening. Gusts will range from 20 to 35 mph across the area, locally higher. Gusty winds continue Monday night into Tuesday morning across the western slopes of the northern Sierra, southern Cascades, and adjacent foothills. Critical fire weather conditions are expected during this time as humidity also decreases due to drier air advecting into the area, especially for areas that saw little to no rainfall. Also to note, winds across the western portion of the Valley may approach Advisory criteria at times during the late morning and afternoon hours tomorrow.

Winds decrease Tuesday afternoon with temperatures pushing back into the 90s in the Valley, and into the 60s and 70s over the mountains as upper ridging moves overhead. Troughing returns for Wednesday, decreasing temperatures just a few degrees from Tuesday.

EXTENDED DISCUSSION (Thursday THROUGH Sunday). Ensemble guidance indicates the potentially for another round of breezy offshore/north winds on Thursday as the upper trough moves east of the CWA. At this point, winds don't look exceptionally strong, but will have to keep an eye on this event. The depth and location of the trough will ultimately decide wind strength. Otherwise, upper level ridging will bring continued above normal temperatures to the region into the weekend. Expect Valley temperatures in the upper 80s to mid 90s with 60s to 80s in the mountains and foothills. Ensemble guidance suggests the potential for a weak closed low or shortwave forming over southern California next weekend, though confidence is low at this time. This could bring some moisture into the Sierra with the potential for isolated mountain showers as well as temperatures cooling toward near normal.

AVIATION. VFR conditions are expected for the next 24 hours. North winds increase after 06Z with gusts from 15 to 30 knots expected at Sacramento terminals and northward. In the mountains, locally higher gusts up to 40 knots possible.

STO WATCHES/WARNINGS/ADVISORIES.
