Showers This Week

Though showers will be limited for the NorthState valley floor Monday, the short wave off to our west will bring ample moisture for Tuesday night into Wednesday.  Would not be shocked to see precip amounts top 1" in some locations.  We clear out for the end of the work week with temps approaching the 60's Friday and Saturday with ridging out a front of our next system with thickness levels increasing. Next system pushes through next Sunday.  A warmer system as we slowly begin to depart from the winter season.

PNA Forecast shows a move back to a neutral phase.

Cold Night Ahead

With the upper level wave off to our south we will return to zonal flow Sunday allowing for temperatures to rebound back into the lower 50's.  However, tonight we easily approach record low temperatures here in the North State valley floor with temperatures ranging from the mid to upper 20's.  The record for Redding is 29 for tomorrow and we should easily establish a new record in the overnight hours.

A little cautious of the mid to high level deck of clouds currently over us, but latest IR imagery shows clouds should begin to depart here in the next hour or so.  Winds will calm to near 0, with thickness levels still fairly low combined with clear skies temps will plummet to below freezing by about midnight to 1 am.

Models seem to be in agreement about the approaching shortwave Monday-Wednesday.  Allowing for unsettled weather in the form of showers depending on elevation.  By Thursday we will begin to clear out for the end of the Workweek. I would not be shocked to see 60 on Saturday with apparent ridging over the North State in front of the next approaching system into next Sunday.
