Weather Discussion for Monday October 15, 2018

Normal high/ low temperatures for Oct 15-Oct 22  (high/low) Redding 79/49, Chico 79/46, Quincy 71/31, Chester 66/30, Susanville 66/34, Grass Valley 72/42, Weaverville 74/34, Mt. Shasta 65/35, Yreka 69/35, Alturas 66/27

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 is still just off the coast.  The map below for the weekend shows a small change as the ridge will move a little east and be over the coast.  The only affect this will have is to stop the periodic north wind outbreaks.  Today through the weekend the north state will be clear.  Temperatures will be above normal.  Gusty northeast to east will occur today and Tuesday with lighter winds after that.

Now for a ray of hope.  The models all show the ridge continuing to move east and weaken.   They also indicate a frontal system moving through between the 22nd and 24th.  One model the European brings system strong enough to bring light precipitation to our area.  The GFS (US) brings a weaker system through.

Weather Discussion for Saturday October 13, 2018

Normal high/ low temperatures for Oct 8-Oct 15  (high/low) Redding 82/51, Chico 81/48, Quincy 72/33, Chester 67/32, Susanville 68/36, Grass Valley 73/44, Weaverville 76/35, Mt. Shasta 68/37, Yreka 72/37, Alturas 69/29

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 large high pressure ridge continues just off the coast.   The map below shows little change expected during the next week.   Skies will be clear, temperatures will be above normal, and gusty north winds will occur today through Monday and again late in the week.

Extended forecast models show the ridge weakening after the 2oth, but not enough to let the rain in.

Weather Discussion for Wednesday October 10, 2018

Normal high/ low temperatures for Oct 8-Oct 15  (high/low) Redding 82/51, Chico 81/48, Quincy 72/33, Chester 67/32, Susanville 68/36, Grass Valley 73/44, Weaverville 76/35, Mt. Shasta 68/37, Yreka 72/37, Alturas 69/29

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.

Once again look at the morning satellite picture and forecast weather map, both below.   Not much difference,  strong high pressure ridge will continue off the west coast.  This means dry for another week to 10 days with above normal temperatures.  There are a few clouds over Northeastern California this morning from a storm moving by well to our north, but for the most part the next week we will see clear skies.  There will be periods of gusty north winds. 

While the models indicate the ridge will weaken around the 20th, they don't really show a rain or even showery pattern.

Weather Discussion for Monday October 8, 2018

Normal high/ low temperatures for Oct 8-Oct 15  (high/low) Redding 82/51, Chico 81/48, Quincy 72/33, Chester 67/32, Susanville 68/36, Grass Valley 73/44, Weaverville 76/35, Mt. Shasta 68/37, Yreka 72/37, Alturas 69/29

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 today.   A strong high pressure ridge is off the coast and as the map below shows will remain there at least through the weekend.  Northern California will be mostly clear with a few clouds at times east of the Sierra Cascade Crest.   Temperatures will be a few degrees above normal.  Gusty north winds will occur in some areas today and again Thursday and Friday. 

There is some indication in the longer range models of the ridge breaking down around the 20th.

Weather Discussion for Saturday October 6, 2018

Normal high/ low temperatures for Oct 1-Oct 8  (high/low) Redding 84/51, Chico 83/49, Quincy 75/34, Chester 70/33, Susanville 70/38, Grass Valley 76/45, Weaverville 78/37, Mt. Shasta 71/37, Yreka 74/38, Alturas 71/31

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.

Last night a low pressure trough and frontal system passed through the Pacific Northwest with the southern end bringing a few light showers to the north end of the state.   Today there will be some lingering clouds over the areas north and east of the valley with a few light sprinkles.  These clouds will clear by sunset.  The rest of the north state will be mostly sunny today with near normal temperatures. 

Sunday through next week we will be under a weather pattern like the one shown on the map below.   High pressure will be off the coast with a low pressure trough to our east.  During this "in between" weather pattern we will have mostly clear skies with slightly above normal temperatures.    Gusty north winds will occur tonight through Monday and again Thursday through Saturday.

Weather Discussion for Wednesday October 3, 2018

Normal high/ low temperatures for Oct 1-Oct 8  (high/low) Redding 84/51, Chico 83/49, Quincy 75/34, Chester 70/33, Susanville 70/38, Grass Valley 76/45, Weaverville 78/37, Mt. Shasta 71/37, Yreka 74/38, Alturas 71/31

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 low pressure area off the coast continues moving slowly eastward and will move across Central and Southern California later today and Thursday.   Today and tonight Northern California will be partly cloudy to cloudy with scattered showers.  Thursday there will a few showers over the areas east of the valley but they will be ending by late afternoon.   Friday the southern end of a frontal system will brush the north end of the state with light rain or showers north of Redding.  

The weekend through the mid part of  next week we will be caught between a large high pressure ridge off the coast and a strong low pressure area over the Great Basin (see map below).   The north state will be mostly clear with near normal temperatures and periods of gusty north winds.

Weather Discussion for Monday October 1, 2018

Normal high/ low temperatures for Oct 1-Oct 8  (high/low) Redding 84/51, Chico 83/49, Quincy 75/34, Chester 70/33, Susanville 70/38, Grass Valley 76/45, Weaverville 78/37, Mt. Shasta 71/37, Yreka 74/38, Alturas 71/31

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 another slow moving closed low pressure area off the coast.  This low is moving very slowly east or southeast and will move inland over Central and Southern California Thursday.  Today through early Thursday Northern California will be partly cloudy to cloudy with scattered showers.  Most of the precipitation will be over the foothills and mountains but isolated activity will also occur over the valley.

Late in the week high pressure will rebuild off the coast (see map below).   This will bring back sunny skies slightly above normal temperatures and periods of gusty north winds.
