Weather Discussion for Wednesday December 13, 2017

Normal high and low temperatures for Dec 11-Dec 18  (high/low)...Redding 55/36, Chico 56/36, Quincy 45/24, Chester 42/21, Susanville 41/22, Grass Valley 54/31, Weaverville 47/29, Mt. Shasta 45/25, Yreka 44/25, Alturas 43/18

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.

Little change in the weather today and Thursday as a strong high pressure ridge continues along the coast.  Friday the high will weaken slightly as a low pressure trough moves through the Pacific Northwest.  This system will bring some clouds to our area with slightly cooler temperatures.  

Saturday through the mid part of next week the high pressure will be back along the coast (see map below).  Look for sunny skies and above normal daytime temperatures.  Gusty north winds are expected Saturday through Monday.  

It looks like a low pressure trough will drop southward across Northern California late next Wednesday or Thursday.  This system does't look like it will have much moisture.

Weather Discussion for Monday December 11, 2017

Normal high and low temperatures for Dec 11-Dec 18  (high/low)...Redding 55/36, Chico 56/36, Quincy 45/24, Chester 42/21, Susanville 41/22, Grass Valley 54/31, Weaverville 47/29, Mt. Shasta 45/25, Yreka 44/25, Alturas 43/18

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 will continue along and over the west coast through Thursday.   Northern California will see sunny skies with some high cloudiness.  Daytime temperatures will continue above normal with light winds.

Late Thursday and Friday the high will weaken as a low pressure trough moves through the Pacific Northwest (see map below).  The north state will see some mid and high cloudiness from this system and temperatures will cool a few degrees. 

Saturday the high pressure area rebuilds along the coast and will hold there through the mid part of next week.   This means more dry and mild weather with gusty north winds Friday through Monday.

The longer range forecast models show a cold low pressure area moving through Northern California around the 20th to the 22nd.   This system does not look like it will have much moisture with it.

Weather Discussion for Saturday December 9, 2017

Normal high and low temperatures for Dec 4-Dec 11  (high/low)...Redding 56/38, Chico 58/37, Quincy 47/26, Chester 43/22, Susanville 44/24, Grass Valley 54/32, Weaverville 48/29, Mt. Shasta 46/27, Yreka 46/26, Alturas 44/18

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.

Today I could actually write a 2 word blog  "no change".  The strong blocking high pressure ridge is still along and over the west coast and won't change much for the next 7 to 10 days (see map below).   We will continue to have sunny skies with some high clouds at times.  Daytime temperatures will continue above normal with light to moderate north winds.  

The really bad news is that while the models show the ridge weakening after the 20th.  They really don't put a rain pattern over the north state until the last 3 to 7 days of the month.

Normal high and low temperatures for Dec 4-Dec 11  (high/low)...Redding 56/38, Chico 58/37, Quincy 47/26, Chester 43/22, Susanville 44/24, Grass Valley 54/32, Weaverville 48/29, Mt. Shasta 46/27, Yreka 46/26, Alturas 44/18

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.

Not a lot to say.   Strong blocking high pressure ridge along and over the west coast and little change is expected for at least the next 10 days (see map below).

Mostly clear days with a few high clouds at times.  Daytime temperatures will continue above normal with periods of gusty north winds.

It looks like the Santa Ana winds will continue in areas of Southern California at least through Saturday.

Weather Discussion for Monday December 4, 2017

Normal high and low temperatures for Dec 4-Dec 11  (high/low)...Redding 56/38, Chico 58/37, Quincy 47/26, Chester 43/22, Susanville 44/24, Grass Valley 54/32, Weaverville 48/29, Mt. Shasta 46/27, Yreka 46/26, Alturas 44/18

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 large high pressure ridge is developing along and over the west coast and will hold there for at least the next week (see map below) and probably 10 to 14 days.  The north state will have mostly clear skies and above normal daytime temperatures.  There will be periods of gusty north winds.

This weather pattern is a classic "Omega Block" and that is why it will be so persistent.  The longer range models still indicate a wetter pattern the last half of December.

Normal high and low temperatures for Nov 27-Dec 4  (high/low)...Redding 58/38, Chico 60/38, Quincy 50/27, Chester 45/24, Susanville 47/25, Grass Valley 56/34, Weaverville 51/31, Mt. Shasta 47/28, Yreka 48/27, Alturas 46/21

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.

Blog is a little late this morning due to internet issues.  This morning's satellite picture (below) show a low pressure area along the Canadian coast moving southward.   Clouds from this system are already over Northern California with rain over the northwestern sections of the state.   The rain will spread slowly southward with light rain over the foothills, mountains and in the valley north of Red Bluff later today and tonight.  Snow levels will be 5000 feet.   The precipitation will end over most areas by Sunday morning with snow showers continuing over the Sierras until midday.   

Monday through next weekend a strong high pressure ridge will be along and over the west coast (see map below).  The north state will have clear skies with above normal daytime temperatures.   There will be periods of gusty north winds during this time.
