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.

Big changes in the weather are starting.   The high pressure ridge that has be over our area is moving eastward as a low pressure trough develops along the west coast.   This morning's satellite picture shows a frontal system out in the Pacific that is moving eastward.   Clouds will increase this afternoon as this system approaches with rain and showers expected over Northern California tonight through Thursday afternoon.   Even through the frontal system will be east of our area by tomorrow afternoon...the low pressure area will linger along the coast through midday Sunday (see map below).   Friday and Saturday the north state will be partly cloudy to cloudy with showers and possible thunderstorms mainly over the the foothills and mountains with a chance in the valley north of Chico.  Friday and Saturday daytime temperatures will be 12 to 20 degrees below normal.  

Sunday afternoon the low will over Northern California and moving slowly eastward.   We will continue to have partly cloudy skies and cool temperatures with showers over the higher elevations north and east of the valley.  

Monday through Wednesday a weak high pressure ridge will be along the coast.  The north state will have partly sunny to sunny skies with temperatures near or just below normal.
