Weather Discussion for Monday September 24, 2018

Normal high/ low temperatures for Sept 24-Oct 1  (high/low) Redding 88/55, Chico 87/52, Quincy 78/35, Chester 75/36, Susanville 74/40, Grass Valley 80/49, Weaverville 84/39, Mt. Shasta 77/41, Yreka 79/41, Alturas 76/33

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.

This morning's satellite picture shows a large high pressure ridge along the west coast and over the Gulf of Alaska. South of the high pressure area is a closed low pressure system.  This pattern is called a "Rex Block" because at times it can become very stable and block or divert the jetstream to the north. 

Today through Thursday the high will dominate our weather.  Northern California will see mostly clear skies with temperatures warming to 10 to 15 degrees above normal by Tuesday and Wednesday.  Gusty north winds will occur today and Tuesday. 

Friday the low will have moved closer to the coast (see map below) and it will move slowly across the north state during the weekend.  Temperatures will cool Friday and we will see increasing clouds.  Saturday and Sunday there will be scattered showers over the foothills and mountains with a chance of isolated showers in the valley.

A stronger low pressure system could slide under the high and over our area early next week.

  1. Could this High for tell how the winter will boil down to? Sometimes that high just stays in place for months. Or not. Usually cut off lows do not have much moisture associated with them

  2. Usually in the winter when the high gets that far north the southern branch of the jetstream will undercut and bring a wet pattern to the north state.
