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.

There is a battle of two weather features occurring.  A strong and active jetstream is running across the Pacific toward the west coast, while a high pressure ridge pushes northward along the coast.  The frontal system shown off the coast on this morning's satellite picture (below) will be forced northeastward.  However, the system is strong enough and has enough moisture that is will bring clouds to Northern California Tuesday and Wednesday.  Light rain will occur over the foothills and mountains, and in the valley north of Chico.  Snow levels will be 6000 feet or higher.  Thursday will be partly to mostly sunny.

Friday the next front will be approaching the coast.  The high pressure ridge will be stronger so this system will bring clouds to the north state with light rain or showers north of Redding.

The ridge will become stronger Saturday through early next week (see map below).  Look for mostly clear skies and above normal temperatures.
