Click here for latest water vapor satellite animation The high pressure ridge is now over California.  There is fog in most of the inland valleys this morning, especially the Sacramento Valley.  The mountains and foothills above the fog will have sunny skies today and above normal temperatures.  The fog in the Redding area is very shallow and should burn off rapidly this morning, but the fog and low clouds will be more persistent further south in the valley … Butte and Glenn counties.   Redding should see temperatures reach the mid- to upper-60s this afternoon. The ridge will rapidly collapse Monday as the low pressure trough in the Gulf of Alaska deepens and shifts eastward.  A weak storm system will bring some clouds to the north state Monday with a few showers over the northwest corner of the state.   A slightly stronger system will bring precipitation to all of northern California late Monday and Tuesday.  Snow levels will start out high but should drop to 3000 to 4000 feet by Tuesday.  Wednesday will partly cloudy to partly sunny across northern California as a colder and drier airmass moves over our area.  The Gulf of Alaska low will continue to get closer to the coast and by Friday (see map below) it will be off the coast with the jetstream running from the Arctic into the back of it.  This low will send a series of colder and wetter storms across the area from late Thursday through the weekend.   ******************************************************************************
