Weather Discussion for Wednesday June 12, 2019

Normal high/ low temperatures for June 10-June 17  (high/low) Redding 91/62 Chico 90/57, Quincy 81/42, Chester 76/40, Susanville 79/46, Grass Valley 80/51, Weaverville 84/44, Mt. Shasta 77/45 Yreka 80/45, Alturas 77/41

High pressure is along the coast.   Over the next few days this high will move a little to the west (see map below).   This morning's satellite picture (below) shows some sub tropical moisture has moved northward over the Sierras.  This moisture will fuel afternoon cumulus clouds over the mountains through Friday with isolated thunderstorms possible north and east of Redding.   Temperatures will continue 8 to 12 degrees above normal.

Saturday through next week the high will continue to dominate our weather.   We will see sunny skies with continued above normal temperatures.  Gusty north winds are expected Sunday through Tuesday.

This morning's satellite picture (below) shows a low pressure system and frontal system off the coast headed toward western Canada and the Pacific Northwest.  Today Northern California will be sunny with temperatures a little cooler than yesterday.

 Thursday the southern end of the frontal system will move through Northern California.   The north end of the state will see a few clouds.   Temperatures Thursday and Friday will cool back to near normal.  Gusty southwest northwest winds will occur Thursday with gusty north winds Friday.

 High pressure begins to rebuild over the western U.S. and along the coast on the weekend and then next week the high will continue over the west.   The north state will be sunny.   Temperatures will bounce back above normal on the weekend and then next week daytime temperatures will be 12 to 18 degrees above normal.  The gusty north winds will end early Sunday.

Weather Discussion for Monday June 3, 2019

Normal high/ low temperatures for June 3-June 10  (high/low) Redding 88/60 Chico 8856, Quincy 79/42, Chester 73/40, Susanville 76/44, Grass Valley 77/50, Weaverville 82/44, Mt. Shasta 73/45 Yreka 78/45, Alturas 74/40

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

Ref question about this years lightning...We have had an above normal occurrence of weak upper level low pressure areas this spring.   These might be weak but they bring cold air aloft in which coupled with the hotter air at the surface, due to the longer days really drops the stability more than we get with monsoonal moisture. 

High pressure is along the coast.  Today through Wednesday we will have sunny skies with some afternoon clouds over the mountains.  Temperatures will continue run 5 to 10 degrees above normal and winds will be light..

Thursday and early Friday an upper level low pressure trough will move through the Pacific Northwest and Canada (see map below).  This will weaken the off shore high pressure area.   Temperatures will cool back to  near normal on Thursday and Friday with a few clouds in the far end of the state.  Gusty north winds will start late Thursday and continue through Friday.

Saturday through early next week high pressure will rebuild along the coast.  The inland areas of the north state will be clear with above normal temperatures.  The gusty north winds will continue through midday Sunday.

Weather Discussion for Saturday June 1, 2019

Normal high/ low temperatures for May 27-June 3  (high/low) Redding 86/58, Chico 84/54, Quincy 76/40, Chester 73/39, Susanville 74/43, Grass Valley 75/50, Weaverville 79/42, Mt. Shasta 70/43 Yreka 76/43, Alturas 72/38

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 is still over the Southwestern U.S. and is moving slowly eastward.   Today and Sunday we will still have enough moisture and instability in the atmosphere to generate afternoon cumulus clouds over the mountains with isolated thunderstorms.  Temperatures today and Sunday will be 5 to 10 degrees above normal.

 Monday and Tuesday high pressure will be along the coast.  The north state will be mostly clear with afternoon clouds over the mountains.  Temperatures will continue above normal and winds will be light.

 Wednesday and Thursday a low pressure trough will move through the Pacific Northwest and western Canada (see map below).  The only affect this system will have on Northern California is a few clouds in the far north and temperatures will cool back to near normal.  

 Friday through the weekend looks mostly clear with above normal temperatures.
