High pressure still holding over the west.  Today will be a repeat of yesterday...except in the valley south of Red Bluff where temperatures will be a few degrees cooler.   Tuesday through Friday the high pressure system gets stronger and moves westward. (see map below).   This will bring very hot weather to the north state.   Wednesday through Friday the north valley will see 108 to 112 degree readings.  A little bit of sub tropical moisture will side up from the south and, Thursday and Friday there could be isolated afternoon and evening thunderstorms along and east of the Sierra Cascade Crest.

Temperatures will begin cooling Saturday as a low pressure trough moves through Canada and pushes the high pressure ridge back to the east.  Temperatures will be back to near normal by next Monday.

The heat is on.   A strong high pressure area is now over the western U.S. and will remain there for the next week. (see map below).   The inland areas of the north state will be sunny with high temperatures well above normal.   Wednesday through Friday some areas on the north valley could be at or above the 110 degree mark.  There will be light to moderate north winds in some areas this morning, but light winds for the rest of the week. 

Temperatures will cool a little around the end of the month and first of August.  There still looks like we could see some mountain thunderstorms at that time also.

Weather Discussion for Wednesday July 20, 2016

Normal high and low temperatures for July 18-July 25 (high/low)...Redding 99/66, Chico 97/61, Quincy 91/45, Chester 87/46, Susanville 89/52, Grass Valley 89/58, Weaverville 96/51, Mt. Shasta 87/52, Yreka 94/54, Alturas 90/46

This blog will be issued every Monday morning and updated if the weather is changing or critical or interesting weather events are occurring.

The low pressure trough off the Canadian and Pacific Northwest coast continues to weaken as high pressure builds or pushes back westward.   This means the inland areas will continue to warm with temperatures back to normal by Friday and the 3 to 8 degrees above normal from the weekend through most of next week.  Winds will be light.  (see map below)

The next week looks like summer...foggy and cool at the coast with sunny and hot inland.  One thing to watch in the extended period...after the first of August...is sub tropical moisture beginning to get pulled northward over California.

Normal high and low temperatures for July 18-July 25 (high/low)...Redding 99/66, Chico 97/61, Quincy 91/45, Chester 87/46, Susanville 89/52, Grass Valley 89/58, Weaverville 96/51, Mt. Shasta 87/52, Yreka 94/54, Alturas 90/46

This blog will be issued every Monday morning and updated if the weather is changing or critical or interesting weather events are occurring.

This morning's satellite picture (below) shows a weak low pressure area off the Pacific Northwest and Canadian coast.   The high pressure ridge has shifted eastward over the Central U.S.   The low pressure area will remain off the coast but gradually weaken.   The inland areas of Northern California will be mostly sunny with a few afternoon cumulus clouds over the northern mountains.   There could be isolated afternoon and evening thunderstorms today and Tuesday   Temperatures will be slowly warming but will remain below normal through mid week.   Light to moderate south to southwest winds will occur in the afternoon.

Friday the high pressure ridge will begin to push or shift back to the west. (see map below).   This will bring back hotter weather.   Friday through at least the mid  part of next week look for temperatures back above normal.

Normal high and low temperatures for July 11-July 18 (high/low)...Redding 99/66, Chico 97/61, Quincy 90/45, Chester 86/46, Susanville 89/52, Grass Valley 88/58, Weaverville 95/50, Mt. Shasta 85/51, Yreka 92/53, Alturas 89/45

This blog will be issued every Monday morning and updated if the weather is changing or critical or interesting weather events are occurring.

Cooling starts today as the high pressure area begins to weaken and shift eastward as a low pressure trough develops off the west coast.    This trough will be at its strongest Sunday and Monday (see map 1 below).  Tuesday through the end of the week the trough will still be off the coast, but will be weaker due to the high pressure area pushing back to the west (see map 2 below).

What this means for Northern California is...Cooling starting today and  continuing through Sunday and Monday.   There will be a few clouds over the far north end of the state Sunday and Monday with the chance of isolated afternoon and evening thunderstorms over Trinity, Siskiyou, and Modoc counties.  Tuesday through the weekend the inland areas of the north state will be sunny with slowly warming temperatures.   Temperatures should be back above normal by Thursday.  Winds will be light.

The low pressure trough that moved through our area this weekend is now over Nevada and continuing eastward.  An interesting rainfall report from the Anderson area....Saturday afternoon 1.17 inches of rain.

The next week looks like a return to a a normal early to mid July weather pattern.  High pressure will rebuild over the western U.S. (see map below-).   This means mostly sunny skies with temperatures rising by Wednesday to a few degrees above normal.   Thursday and Friday temperatures will continue above normal.  Winds will be light.

Saturday the high will weaken as a low pressure trough moves into western Canada and the Pacific Northwest.   The north state will still be sunny but temperatures will drop back to a little below normal for the weekend.
