This blog will be issued every Monday, Wednesday, and Saturday morning and updated if the weather is changing or critical or interesting weather events are occurring.
The weak upper level low is still off the coast and will remain there through Thursday. There is not a lot of moisture with this system. However, it will provide enough instability to trigger afternoon and evening thunderstorms over the higher elevations today and Thursday. Temperatures today and Thursday will be near or slightly above normal with south to southwest winds in the afternoon. Friday the low will move south and dissipate. The inland areas of the north state will be sunny with a few afternoon clouds along the Sierras. Temperatures will be warmer.
Saturday a very strong high pressure ridge will be back over the west and will hold there through next week (see map below). More very hot weather is instore for the inland areas of the north state with afternoon temperatures 15 to 20 degrees above normal. We may see some monsoonal moisture ride northward around mid week for a chance of thunderstorms over the Sierras.
