Today begins the warm up that should peak on Thursday. A ridge is going to begin building over the Southwest and build Northward throughout the week bringing warm air to Northern CA by midweek.

Let’s start with the mountains first above 7000 ft. Temps will be in the 40′s this weekend, then the 50′s Monday-Wednesday, and then into the 60′s on Thursday.

At lake level we will be in the 50′s this weekend, then the 60′s Monday & Tuesday, and then possibly breaking 70 degrees Wednesday and Thursday.

There will be some retrogression of the ridge in the Central Pacific as we go towards next weekend and into the second week of May. That will allow some troughing and storms into the Pacific NW. The trough is going to have to battle the ridge through over the Southwest.

Right now it looks as if we may just see some cooler temps next weekend. The best shot at possible precip would be the beginning of the second week of May if the trough can dig down the coast a little more.

After that it looks as if we could have an even bigger warm up around mid-month. I have been expecting May to be a warm month especially in the middle of the month looking at the teleconnection forecast
