A cold week ahead

We are stuck in a pretty cold weather pattern this week. A large, deep winter-style trough of low pressure is right on top of us. This does two things: ushers in cool air and also allows occasional low pressure disturbances to work over the area.

The cool air is actually much drier than the atmospheric river air of last week, so even though some showers are expected Wednesday into Thursday; lighter amounts (under .40″ is expected). The air is also cold so we’ll be following potentially low snow levels mid-week, in the night and morning hours it could drop as low as 1500-2000 ft.

Lows tonight in the interior will drop into the mid-20s again, similar to Monday morning. At the coast lows will be in the upper 20s and lower 30s. Southcoast temperatures will be in the upper 30s and lower 40s. For the coastal valleys there is a freeze warning late tonight into Tuesday morning.

The extended forecast looks dry Friday through Saturday but Sunday and Monday are questionable. There looks to be another cold and mostly moisture deprived low dropping into California but at this point even if it rained it wouldn’t be much. Even though the jet stream looks fast and active, I don’t see much after that until the following weekend of March 4th.
