Different day same forecast.  The satellite picture and map below show the high pressure ridge over the western U.S. will get stronger.  Models indicate this ridge will say in place through the first 10 days of September.  The inland areas of Northern California will be hot and dry with daytime temperatures 8 to 12 degrees above normal and even up to 15 degrees above normal by the weekend.  Locally gusty north winds will occur today through midday Tuesday, after that winds will be light nights and mornings and south to southwest in the afternoon.

  Normal high/ low temperatures for Aug 24-Aug 31  (high/low) Redding 96/62, Chico 94/57, Quincy 87/41, Chester 82/41, Susanville 84/47, Grass Valley 85/54, Weaverville 91/46, Mt. Shasta 82/47, Yreka 88/49, Alturas 85/40

The summertime high pressure area that has been over the Southwestern U.S. will get stronger over the week (see map below).  This means continued clear (smoky) with temperatures above normal.  Winds will be light nights and mornings and south to southwest in the afternoon most  days.  However there will be locally gusty north winds late Sunday and Monday. 

Longer range models show some weakening of the high after the first week of September.  The thing to watch is if the orientation of the high allows southeast flow aloft we could see more sub tropical moisture pulled northward.

This morning there is a very weak upper level low pressure area off the coast.  The satellite picture, below, shows very little cloudiness associated with it.  However, as it passes across Northern California this afternoon it will trigger isolated thunderstorms over the higher elevations from Mendocino county northward to the west and Plumas county northward to the east.  Temperatures today will be near normal with south to southwest winds increasing this afternoon.  



Thursday through early next week a high pressure ridge will be back over our area (see map below).  Skies will be mostly clear.  Temperatures will warm back to above normal.  Winds will light nights and mornings and southwest in the afternoon.  

One thing to note is the difference between the European model and the GFS model.  The GFS  keeps the ridge over us early next week.  The European has a different pattern which still have clear skies, but cooler temperatures, along with gusty north to northeast winds.

The large high pressure area over the western U.S. is once again pulling subtropical moisture northward over Northern California.  This is resulting in scattered showers and a few thunderstorms over the north state this morning.  Surges of subtropical moisture will move across the state through Wednesday.  There will be continue isolated to scattered showers and possible thunderstorms.  However, most of the activity will be over the foothills and mountains  Temperatures through Wednesday will be near normal.  Winds will be south to southwest in the afternoons.

Thursday through at least early next week we will still be under a high pressure ridge (see map below). Skies will be mostly clear with some afternoon cumulus over the mountains.  There could be isolated mountains thunderstorms Friday.  Temperatures will be above normal.  Winds will be southwest to northwest increasing in the afternoons.

Normal high/ low temperatures for Aug 17-Aug 24  (high/low) Redding 97/62, Chico 94/57, Quincy 87/41, Chester 83/43, Susanville 85/47, Grass Valley 86/54, Weaverville 92/47, Mt. Shasta 83/48, Yreka 89/51, Alturas 86/41

The strong high pressure area is still over the western U.S.  The southerly flow around the westside of the high has tapped a good source of subtropical moisture and is pulling it northward over California.  The moisture mixed with the hot and unstable airmass over our area is triggering widespread thunderstorms.  The thunderstorms will continue today.  Tuesday the storms will be along and east of the Sierra Cascade Crest.  Gusty west to northwest winds will occur in some areas today and Tuesday.

The high looks like it will remain over the western U.S. for the next 7 to 10 days (see map below).  Wednesday and Thursday temperatures will be slightly above normal.  However, by the weekend and early next week we will see temperatures back to 5 to 10 degrees above normal.  It looks like another surge of subtropical moisture could be pulled northward late in the weekend or early next week.

Well we are stuck in a very hot weather pattern.  The satellite picture below and forecast map show the strong high pressure ridge will continue over the western U.S.  This means for the next week we will see daytime temperatures 10 to 15 degrees above normal. Sunday and Monday we may see a few clouds as subtropical moisture gets pulled northward.  This moisture will allow thunderstorms to form over the foothills and mountains.  Winds will be mostly light increasing from the south and southwest in the afternoon.  

Longer range forecast models are still dry but do show some cooling after the 25th.

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.

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.

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.

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.
