National Weather Service Sacramento CA
116 PM PDT Sun Sep 22 2024

.Synopsis...
Warm and dry weather continues with breezy north winds at times
for the Sacramento Valley and adjacent foothills. Elevated fire
weather concerns will be possible into late Monday.

.Discussion...
Warm and dry pattern continues for interior NorCal the next
several days as high pressure builds in from the eastern Pacific.
High temperatures will be above normal with lower elevations
reaching the mid to upper 90s, and some areas potentially reaching
triple digits on Monday and Tuesday with resulting in widespread
Moderate HeatRisk. The NBM has a 10 to 40% probability of temps
reaching or surpassing 100 degrees around Redding on Monday, and
in the Sacramento Metropolitan area and northern San Joaquin
Valley on Tuesday.

Northerly flow aloft will support some locally breezy north winds
in the valley again this evening, which will continue to
gradually lower humidity. A little stronger north wind will be
possible Monday into early Tuesday which combined with low RH will
result in elevated fire weather conditions.

By Wednesday, ridging is forecast to shift east as a weak trough
develops over the region bringing increased onshore flow, cooler
temperatures and higher humidity.

&&

.EXTENDED DISCUSSION (Thursday THROUGH Sunday)...
Upper ridging over interior NorCal is suppressed through the
remainder of the week into the weekend as series of short wave
troughs progress through the Pacific NW. Dry weather expected
with seasonable temperatures.
