The trough moved through, took the top off the valley inversions and things cleared out. However, my forecast for the Sacramento Valley really sucked … (as my wife told me when we were standing outside in the 34-degree fog). I had expected that the trough would be strong enough to break up the inversion in the north end of the Sacramento Valley. It did break it up but it took till about 3:00 a.m. this morning to do it. There is still some fog this morning in the north end of the valley but it is very shallow and should burn off by late morning. (I am at the 700-foot elevation in west Redding and it is sunny this morning). I would expect the fog to be gone by midday in Tehama and Glenn counties but it could linger over Butte county until mid afternoon.
So other than the lingering fog in parts of the Sacramento Valley, today will sunny over all of northern California, with temperatures a little below normal for this time of year. Tonight will be cold and mostly clear except for fog in the valleys. The Sacramento Valley will have patchy fog tonight with light northerly winds in many areas. However, wind-sheltered areas will be in the mid- to upper-20s. Monday will be a repeat of today with another cold night Monday night.
This morning’s satellite picture shows a high pressure ridge connecting high pressure areas in the Pacific with a very large high pressure area over Alaska and the Arctic. The jetstream is still expected to split and break through the ridge next week. The map below for Wednesday shows this. The difference now is that the high pressure area on the southern end of the ridge is forecast to be closer to the southern California coast. This means the southern branch of the jetstream will deflected northward over the Pacific Northwest and the far north end of California. There will be a series of weak storms reaching northern California. The first will be Tuesday and early Wednesday with the second late Wednesday and Thursday and then a very weak system next weekend. Snow levels will start out at 2,500 to 3,500 feet Tuesday but will locally lower in valleys where cold air is trapped. The snow level will rise to 4,000 to 5,000 feet on Wednesday and Thursday. ******************************************************************************
