***HOTTER***


Normal high and low temperatures for July 31-Aug 7 (high/low)...Redding 99/65, Chico 96/58, Quincy 90/43, Chester 86/45, Susanville 89/51, Grass Valley 89/57, Weaverville 95/49, Mt. Shasta 86/50, Yreka 92/53, Alturas 89/43

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.

A very strong high pressure ridge is now over the western U.S.   Record or near record high temperatures are expected through Wednesday.   The hottest days will be Tuesday and Wednesday.   The smoky skies will keep the temperatures down in some areas.  Without the smoke and with light north winds Redding would be close to it's all time official high of 118 on Tuesday and Wednesday.   However,  with the smoke and wind flow I expect we will be 114 to 116 on those days.   Winds will be light.

Temperatures will start to slowly cool starting Thursday but will remain above normal through the weekend.  The cooling will be a result of the high slightly weakening (see map below) and sub tropical moisture be pulled northward over our area.   Thursday through the weekend we will have partly to mostly sunny skies with thunderstorms mainly over the foothills and mountains.   There is a chance of thunderstorms over the valley Thursday night and Friday.

***HOT AND HOTTER***


Normal high and low temperatures for July 24-July 31 (high/low)...Redding 100/67, Chico 97/61, Quincy 91/45, Chester 88/47, Susanville 90/52, Grass Valley 90/58, Weaverville 97/50, Mt. Shasta 89/52, Yreka 94/54, Alturas 90/46

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 high pressure ridge continues over the western U.S. and will get stronger through midweek (see map below).   Temperatures will be rising, with the hottest days Tuesday and Wednesday.  Temperature records will be broken in many areas during this hot spell, with some north valley areas around or just above the 115 degree mark by Tuesday.

There will be some afternoon cumulus clouds with a chance of isolated thunderstorms east of the Sierra Cascade Crest this afternoon and Sunday afternoon.

Temperatures will start to cool starting Thursday as the high pressure area weakens.  It also looks like sub tropical moisture will be pulled northward and this will result in an increase in mountain thunderstorms Thursday through Saturday.

Weather Discussion for Wednesday July 26, 2017

Normal high and low temperatures for July 24-July 31 (high/low)...Redding 100/67, Chico 97/61, Quincy 91/45, Chester 88/47, Susanville 90/52, Grass Valley 90/58, Weaverville 97/50, Mt. Shasta 89/52, Yreka 94/54, Alturas 90/46

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 pressure area that has been off the coast is now dissipating as it moves eastward and hits the large high pressure area that continues over the western U.S.  Today the north state will be mostly sunny with afternoon cumulus clouds over the mountains with a chance of showers and thunderstorms over Siskiyou, Modoc, and Lassen counties.  Temperatures will be about like yesterdays. 

Thursday through at least the mid part of next week a strong high pressure ridge will be...once again...over the western U.S. (see map below).   This means a return of temperatures 6 to 12 degrees above normal.   One thing to note....on this morning's satellite picture (below) you see 2 hurricanes in the southeastern Pacific.   These storms will be weakening and moving northward over the next several days.  Some of this moisture could reach northern California Sunday or Monday and trigger more mountains thunderstorms.

Normal high and low temperatures for July 24-July 31 (high/low)...Redding 100/67, Chico 97/61, Quincy 91/45, Chester 88/47, Susanville 90/52, Grass Valley 90/58, Weaverville 97/50, Mt. Shasta 89/52, Yreka 94/54, Alturas 90/46

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.

A strong high pressure area continues over the western U.S.  There is a weak upper level low pressure area off the Northern California coast.  The low will remain off the coast through Tuesday and then dissipate Wednesday as it moves into the high pressure area.   This morning's satellite picture (below) shows the southerly flow around the west side of the high pressure area is pulling subtropical moisture (clouds) northward.   This moisture coupled with the instability of the low will result in afternoon and evening thunderstorms today and Tuesday over the higher elevations to the north and east of the valley.  Temperatures today and Tuesday will be normal to 5 degrees above normal.  Winds will be light in the morning and southerly in the afternoon.  Wednesday we will see mostly sunny skies with a chance of afternoon and evening thunderstorms along and east of the Sierra Cascade Crest.  Temperatures will be near normal.

Thursday through the weekend the high pressure ridge rebuilds over the west (see map below).  This will result in hotter weather.

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.

 Strong high pressure ridge continues over the west.  Today we will see high temperatures 10 to 15 degrees above normal with some areas of the north valley over 110 degrees.  The high pressure ridge will remain over western U.S. for the next week.  

This morning's satellite picture shows a weak upper level low off the coast.  This weak low will continue eastward and then dissipate late Tuesday and Wednesday as it runs into the high pressure ridge.  However, the southerly flow around the west side of the high pressure area will pull moisture northward.  This moisture coupled with the instability of the low pressure area will bring an increase in afternoon and evening cumulus clouds with thunderstorms over the mountains starting Sunday.  Sunday we will see a few afternoon thunderstorms over the Sierra Cascade area.   Monday and Tuesday there is a chance of afternoon and evening thunderstorms over all of the higher elevations of the north state.  Temperatures will start to cool Sunday and by Wednesday will be back to near normal.  

Late next week and next weekend temperatures will warm back above normal.

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 high pressure ridge has shifted a little eastward.  This has allowed temperatures to cool to near normal.   Today and Thursday the inland areas of Northern California will be sunny with near normal temperatures.  Winds will be light.

Friday through early next week the high pressure ridge will rebuild over the western U.S. (see map below).  Skies will continue mostly clear...but there will be increased afternoon cumulus clouds over the mountains Sunday and Monday with a slight chance of a shower or thunderstorm.  Temperatures will warm back above normal.  

Longer range forecast models show the ridge weakening late next week which will bring a little cooling.

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 high pressure ridge that has dominated our weather is beginning to weaken and move eastward as a low pressure trough moves into western Canada.  Today the inland areas of the north state will be sunny with temperatures a couple degrees cooler than yesterday.   Tuesday through Thursday temperatures will cool to normal or a couple of degrees below normal.  This means Redding should end its' run of 100 degree days.  Winds will be light in the morning and south to southwest in the afternoon.

Friday through the weekend the high pressure area will rebuild over the western U.S. (see map below).   This will warm temperatures back to above normal.

Still looking for a change in the weather to write about.  High pressure is still over the western and central U.S.   It will weaken a little late Sunday as a low pressure area moves into western Canada (see map below).  

The next 7 to 10 days the inland areas of Northern California will be clear. Daytime temperatures today through Sunday will be 3 to 8 degrees above normal and then cool back to near normal early next week.  Winds will be light.

A strong high pressure ridge is just to our east.  There is a little sub tropical moisture moving northward around the west side of the high and this will bring isolated thunderstorms this afternoon and evening along and east of the Sierra Cascade Crest.  Temperatures today will be about like yesterday or a couple of degrees cooler.  Southerly winds will increase this afternoon. 

Tuesday the high pressure ridge will shift a little westward and will remain over the western U.S. through at least early next week (see map below).  Tuesday through the weekend the inland areas of the north state will be sunny with daytime temperatures 4 to 8 degrees above normal.  This means more 100 degree readings for the north valley.
