 Normal high/ low temperatures for Aug 10-Aug 17  (high/low) Redding 98/64, Chico 96/58, Quincy 89/43, Chester 85/44, Susanville 88/49, Grass Valley 88/55, Weaverville 94/47, Mt. Shasta 86/49, Yreka 91/52, Alturas 88/41

  
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 only change in our weather is the high pressure area over the western U.S. will get stronger by this weekend (see map below).  This means hotter weather.  Today and Thursday the inland areas of the northstate will be clear with temperatures normal to slightly below.   Things start warming Friday and by the weekend daytime temperatures will be 8 to 12 degrees above normal.   Winds will be light.  

The heat continues into early next week with some cooling by midweek  We could see some subtropical moisture pulled northward early next week and this will trigger afternoon and evening mountain thunderstorms.

Hot again today with high temperatures around 10 degrees above normal.  There will be some afternoon cumulus clouds over the mountains north and east of the valley with isolated thunderstorms.  Winds will increase from the south in the afternoon.

Still no sign of the strong high pressure ridge moving or weakening (see map below).  Other than the chance of afternoon thunderstorms Tuesday along and east of the Sierra Cascade Crest skies will be clear for the next week.  Temperatures will be near normal Tuesday and Wednesday but will warm back to above normal for Friday and the weekend. Winds will be light nights and mornings with south to southwest winds in the afternoons.

High pressure will continue over the western U.S. for at least the next week.  Today and Sunday the inland areas of Northern California will be mostly sunny with high temperatures 4 to 8 degrees above normal.  Winds will be light.  

Monday we will still have above normal temperatures.  However, some subtropical moisture will get pulled northward over California.  We will see a few clouds with afternoon and evening thunderstorms over the foothills and mountains.  

Tuesday through next week looks clear.  Temperatures will be near normal with light winds. 

Longer range models don't show much change.

Weather Discussion for Wednesday Aug. 5, 2020

Normal high/ low temperatures for Aug 3-Aug 10  (high/low) Redding 98/64, Chico 96/58, Quincy 90/43, Chester 86/44, Susanville 89/51, Grass Valley 89/56, Weaverville 95/48, Mt. Shasta 86/49, Yreka 92/52, Alturas 88/43

High pressure is over the western U.S. and will hold there for at least the next week (see satellite picture and map below).  There are a few weather features to watch today.  First there will be some cumulus clouds over the mountains north of Redding today with isolated thunderstorms possible over Siskiyou and Modoc counties.  Second, overnight there was a strong push of marine air through the Delta and this morning low clouds extend from the Bay Area to north of Sacramento.  This cooler air will drop the temperatures in the valley today to several degrees below normal.  

Thursday through next week the inland areas of Northern California will be mostly clear.  Temperatures Thursday will be slightly below normal, but will be warming and by the weekend will be 4 to 6 degrees above normal.  Winds will be light.

Normal high/ low temperatures for Aug 3-Aug 10  (high/low) Redding 98/64, Chico 96/58, Quincy 90/43, Chester 86/44, Susanville 89/51, Grass Valley 89/56, Weaverville 95/48, Mt. Shasta 86/49, Yreka 92/52, Alturas 88/43

Today and Tuesday the inland areas of Northern California will be mostly clear with temperatures slightly above normal.  Winds will be light becoming south to southwest in the afternoon.  Wednesday the high pressure area that dominates our weather will weaken as a low pressure trough moves through Canada.  This will allow temperatures to cool a few degrees.  There will also be a chance of isolated afternoon and evening thunderstorms Wednesday over the areas north of Redding.  Light moderate southwest winds will occur Wednesday afternoon.

Thursday through at least the weekend high pressure will be over the western U.S. (see map below).  Skies will be clear and temperatures will warm to 3 to 6 degrees above normal by the weekend. Winds will continue relatively light.
