Weather Discussion for Saturday June 24, 2017

Normal high and low temperatures for June 19-June 26 (high/low)...Redding 93/63, Chico 93/58, Quincy 84/43, Chester 80/4W2, Susanville 83/47, Grass Valley 83/53, Weaverville 88/46, Mt. Shasta 80/47, Yreka 84/48, Alturas 81/41

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.

Cooler weather is on the way.   Today the foothills and higher elevations will see temperatures about like yesterday.   However, marine air is moving through the delta and up the valley.  Most of the cooling from the marine air will be south of Red Bluff but Redding should be a couple of degrees cooler.  Sunday we will see a few degrees more cooling.    This morning's satellite picture shows a weak upper level low pressure area off the coast.   This system will trigger afternoon and evening thunderstorms today over the Sierra from Tahoe southward.   Sunday the low will lift northeastward and all of the higher elevations of Northern California will have a chance of isolated afternoon and evening thunderstorms.  

Monday through Wednesday there will be a low pressure area over western Canada, which will keep the high pressure ridge suppressed (see map below).   During this time the inland areas of the north state will be mostly sunny and temperatures will be near normal.  There is a chance of isolated afternoon thunderstorms over Siskiyou, Modoc, and Lassen counties Monday. 

Thursday through the weekend the high pressure ridge will push back northward.  This will warm temperatures back to a few degrees above normal.

Little change in the weather through Saturday, the strong high pressure ridge will continue over the western U.S. and off the west coast.   High temperatures will continue at record levels.  Gusty north winds will occur today and Thursday.  

Sunday we will see a few degrees of cooling.  More cooling will occur Monday and Tuesday as the high pressure weakens due to a low pressure area moving into western Canada (see map below).  Temperatures by Tuesday will be down to normal or a few degrees above.  Sunday afternoon and Monday afternoon there will be isolated thunderstorms over the northern and eastern mountains.

Weather Discussion for Monday June 19, 2017

Normal high and low temperatures for June 19-June 26 (high/low)...Redding 93/63, Chico 93/58, Quincy 84/43, Chester 80/42, Susanville 83/47, Grass Valley 83/53, Weaverville 88/46, Mt. Shasta 80/47, Yreka 84/48, Alturas 81/41

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.

A strong high pressure ridge is over the western U.S. and will hold there for the next 7 days (see map below).  The flow around the high is puling a little subtropical moisture northward and this will result in isolated afternoon and evening thunderstorms today and Tuesday.  There is a slight chance of the storms moving out across the north end of the valley late this afternoon.   Wednesday through the weekend the north state will be mostly clear inland with fog and low clouds at the coast.

Temperatures for the next 7 days will continue 10 to 18 degrees above normal.   The Redding and Red Bluff areas will continue a couple degrees below or above 110.  Strong and gusty north winds will occur Wednesday through Friday morning.

Get ready for hot weather....

This past weekend saw temperatures 10 to 20 degrees below normal...next weekend we will have temperatures 10 to 15 degrees above normal.

The low pressure area is now over Nevada and moving eastward.   However, the flow around the low will push clouds over the eastern portions of Northern California through this evening with a few showers along and east of the Sierra Cascade Crest.  The rest of the north state will be sunny and a little warmer.

Tuesday high pressure begins to build over the western U.S. and along the west coast.  The high will continue to strengthen through the weekend with a strong high pressure ridge continuing over our area through the mid part of next week (see map below)   The inland areas of the north state will be mostly sunny with temperatures back up to normal by midweek.  The warmup will continue and by Friday and the weekend some areas of the north valley will be at or just over the 100 degree mark. Winds will be light.

Normal high and low temperatures for June 5-June 12 (high/low)...Redding 87/59, Chico 87/55, Quincy 79/42, Chester 74/39, Susanville 76/44, Grass Valley 77/50, Weaverville 82/45, Mt. Shasta 73/45, Yreka 80/45, Alturas 75/40

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.

This morning's satellite picture (below) shows a cold, for this time of year, low pressure area just off the Oregon and Northern California coast.  The low will move slowly across our area tonight and Sunday and will be over Nevada by Monday.  Today and Sunday the low will generate bands of showers and possible thunderstorms as it moves eastward.  Most of the showers will be over the foothills and mountains but there is a chance of showers in the valley north of Chico.  Snow levels will be 5000 to 6000 feet.  Daytime temperatures will continue 10 to 18 degrees below normal.  Most of the north state will be sunny Monday but there will still be clouds and a few showers along and east of the Sierra Cascade Crest.

Tuesday through next weekend high pressure will rebuild over the western U.S. and along the west coast (see map below).   The north state will be sunny and warmer with temperatures warming.  Daytime high temperatures will be back to normal by Friday and by the weekend some north valley locations could break the 100 degree mark.  Winds will be light.
