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.

    Record Low was actually 26 not 29 for Feb. 27th, set back in 1971. Winds failed to subside so temps remained well above warning criteria last night. The official low at RDD was 32. Chico managed 28, Redbluff 31, Corning 30, and Oroville 30. So temps basically differ from location to location depending on local micro-meteorology and topography last night and of course any given night.

    As I gain experience forecasting for the North State I will begin to pick up on these local features and biases.
