This blog will be issued every Monday morning and updated if the weather is changing or critical or interesting weather events are occurring.
A weak low pressure trough and frontal system are now moving across Northern California. Most precipitation has been over the higher elevations with a few light showers in the valley. Snow levels are around 4000 feet. Skies will be clearing later today as the low moves into Nevada and drops southward. Thursday and Friday high pressure will be along the coast with a low pressure area over the southwestern U.S. The northstate will be mostly sunny with gusty north to northeast winds and normal temperatures.
The offshore high pressure ridge will move back to the west Saturday. Sunday through Tuesday we will be under a pattern like the one shown on the map below. While the jetstream is over or south of our area it is dropping from north to south and storms moving along it won't have a chance to pickup much moisture. Clouds will increase Saturday with a weak storm late Saturday and Sunday. Precipitation amounts will be light with snow levels 3000 to 4000 feet. A slightly stronger system will move through Sunday night and Monday. This will be a colder storm with snow levels 2000 to 3000 feet.
There will be a break Tuesday and then a stronger frontal system will move in from the west Wednesday.
