A quick update from my post yesterday. If you missed it, click here to view the complete post.
My thoughts have changed little, and the models continue to be pretty darn close through Tuesday. Expect well-below-normal temperatures Monday and Tuesday with a shower, even a thundershower, chance spreading east and south those two days. A deep marine layer in the Los Angeles and San Diego area Tuesday could mean a little light rain and drizzle in the morning hours, then an afternoon shower.
After Tuesday, the models part ways again with the European moving the center of the low east into the southern Nevada area with a trough hanging back over Southern California. However, the GFS still has a well-developed, closed low near Pt. Conception Wednesday and a little farther south over the Los Angeles Basin on Thursday. Obviously one model would have a better chance for a shower or thundershower than the other. As I explained yesterday, we are in a REX block and things evolve very slowly in these blocks. I am leaning more toward the slower GFS because of that.
No matter which model, there is at least two days for the chance of rain and temperatures are going to well below normal.
Some of the coldest weather in a long time has been occurring and continued even to this morning.
This storm is going to bring about accumulating snow to places that don’t see it often.
In the citrus areas from the San Joaquin Valley to northern Ventura County expect a hard freeze in most area
a well established spoke of energy rotated northeast and is bringing some areas a LOT more rain than the sprinkle or light shower I predicted.
It looks like the Cascades of Washington will get some important snow Sunday and Monday.
Southern California looks like it will get wet Thanksgiving and Black Friday.
