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

Well...big changes in the next week and weather we don't usually expect in early June.

High pressure is still over the west but is weakening as a weak frontal system approaches the coast.  Today we will have partly sunny skies with temperatures a little warmer than yesterday.  Late tonight and Sunday a weak frontal system will move across the state with a few clouds.  There will be isolated light showers over the areas north of Redding.

Monday and Tuesday the high pressure ridge bounces back over the west coast.   We will see clear skies with temperatures a few degrees above normal.  Winds will be light. 

Wednesday the big change starts as low pressure trough deepens off the coast with increasing clouds and cooler temperatures.  Wednesday night through midday Saturday a deep...for this time of year...a low pressure trough will be along the west coast (see map below).  During this time the north state will see partly cloudy to cloudy skies with periods of rain or showers.  Temperatures will be 10 to 20 degrees below normal by Thursday and Friday.  

The trough will be east of our area by Saturday night.   However, a weaker trough will move across the area Monday with showers over the coastal and northern mountains.
