Weather Discussion for Tuesday January 3, 2017

Normal high and low temperatures for Jan 2-Jan 9 (high/low)...Redding 52/35, Chico 52/34, Quincy 44/22, Chester 40/19, Susanville 38/19, Grass Valley 52/31, Weaverville 45/27, Mt. Shasta 42/25, Yreka 43/24, Alturas 40/14

This blog will be issued every Monday morning and updated if the weather is changing or critical or interesting weather events are occurring.

This morning's satellite picture (below) shows the low pressure area off the coast merging with the warmer moister air from the west.  The boundary between the airmasses is a little further north than was forecast yesterday and this has modified the cold air in the north end of the state.  Northern California will see locally heavy precipitation later today and tonight with snow levels 1000 to 1500 feet from Redding northward and 2000 to 3000 feet south of Redding.  Snow levels will rise later tonight to 3500 to 4500 feet.  The low will be east of our area by late Wednesday.  The precipitation will turn to showers Wednesday and end Wednesday night.  Snow levels Wednesday will be 3000 to 4000 feet. 

Thursday and Friday the north state will be partly to mostly sunny, with near normal temperatures.  

A large low pressure trough will be off the coast by Saturday and this will send a series of frontal systems across our area. (see map below).   Wet weather starts Saturday afternoon and continues at least through mid week.  Snow levels will start out 5000 to 6000 feet but lower by Monday or Tuesday.

  1. What's your take on the risk of heavy flooding due to high snow levels for the weekend event?

  2. If the models are correct it could become a problem by next Mon or Tue. However, I think the snow levels may drop a little by then to offset the runoff.
