Storm Snow Total Update: Halloween Storm 10/30-11/1

The Halloween storm bringing rain/snow over the past two days is starting its trek out of the region this morning.

Low level water vapor imagery ~5am PST on 11/1/26 showing the upper level low moving inland north of the Bay Area with drier air wrapping in on the backside.

Skies will begin clearing today as the system moves on, but expect some clouds to linger and potentially drop a few convective snow showers across the mountains. Some light additional accumulations are possible, but generally < 1". N-NE flow will kick in as the low moves east of the region, keeping temperatures brisk in the low to mid 30s above 7000' today. Tonight will be cold with clear skies, calm winds and a new snowpack allowing for efficient cooling. Expect lows well into the 20s to upper 10s (especially in low lying areas) by Monday AM.
