Normal high and low temperatures for July 17-July 24 (high/low)...Redding 99/67, Chico 97/61, Quincy 90/44, Chester 86/46, Susanville 90/52, Grass Valley 88/57, Weaverville 94/50, Mt. Shasta 87/52, Yreka 93/54, 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 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.

Weather Discussion for Monday July 17, 2017

Normal high and low temperatures for July 17-July 24 (high/low)...Redding 99/67, Chico 97/61, Quincy 90/44, Chester 86/46, Susanville 90/52, Grass Valley 88/57, Weaverville 94/50, Mt. Shasta 87/52, Yreka 93/54, 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 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.

Monday the high pressure area will shift a little eastward and hold there through Thursday (see map below).   Temperatures will start to cool Monday and by Wednesday should be down to about normal.  Redding could drop to 97 to 99 and break the 100 string.  Winds will be light.

Normal high and low temperatures for July 10-July 17 (high/low)...Redding 98/66, Chico 97/61, Quincy 90/44, Chester 86/46, Susanville 89/51, Grass Valley 88/57, Weaverville 94/50, Mt. Shasta 86/51, Yreka 92/53, Alturas 89/45

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.

Normal high and low temperatures for July 10-July 17 (high/low)...Redding 98/66, Chico 97/61, Quincy 90/44, Chester 86/46, Susanville 89/51, Grass Valley 88/57, Weaverville 94/50, Mt. Shasta 86/51, Yreka 92/53, Alturas 89/45

Not much change in the large scale weather pattern for the next week.   High pressure is over the western U.S. and will remain there (see map below).  The high will weaken a little and then strengthen and this will result in changes in our daytime temperatures.  Expect mostly clear skies inland for the next week.  Temperatures will slowly cool to near normal by midweek and then warm again with daytime high temperatures 8 to 12 degrees above normal by the weekend.  Winds will be light nights and mornings and southerly in the afternoon.

Weather Discussion for Wednesday July 5, 2017

Normal high and low temperatures for July 3-July 10 (high/low)...Redding 98/66, Chico 95/60, Quincy 88/43, Chester 84/44, Susanville 87/49, Grass Valley 86/55, Weaverville 92/48, Mt. Shasta 84/50, Yr.eka 89/50, Alturas 86/43

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 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.
