Normal high/ low temperatures for April 27-May 4 (high/low) Redding 78/51, Chico 78/48, Quincy 68/35, Chester 63/32, Susanville 65/36, Grass Valley 67/42, Weaverville 71/36, Mt. Shasta 65/36, Yreka 68/36,  Alturas 64/32
  
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 weak low pressure area off the coast and moving slowly eastward.  Ahead of the low quite a bit of high cloudiness has been pulled northward over California.  The low will bring a chance of isolated showers over the higher elevations late today and early Thursday.  Skies clear out during the day Thursday and Friday looks mostly sunny.  Temperatures Thursday and Friday will be near normal and locally gusty south to southwest winds will occur this afternoon.

Saturday the jetstream begins moving southward and this allows a weak low pressure trough to move across the north state late Saturday and early Sunday (see map below).  This system will bring light showers mainly to the foothills and mountains Saturday afternoon through early Sunday.  There is a chance of a shower in the north end of the valley. Temperatures will cool to several degrees below normal by Sunday.  Gusty southwest to northwest winds will occur Saturday afternoon and Sunday.

Monday we will see partly to mostly sunny skies with near normal temperatures.  Tuesday the high pressure ridge is back over the coast and Tuesday through the end of the week looks clear with warmer temperatures.  Gusty north winds will occur Tuesday through early Thursday.

The mid an high clouds over Northern California this morning are from a frontal system moving inland well to our north.  These should clear out later today.  Temperatures will be above normal and winds will be light.  Tuesday looks sunny with warmer temperatures.  Some areas of the north valley could reach the 90 degree mark.  Winds will be light.

Wednesday afternoon a weak low pressure trough will move across the north state with a few clouds and scattered light showers or thunderstorms mainly over the foothills and mountains with a chance of an isolated shower in the north end of the valley.  Light to moderate south to southwest winds will occur Wednesday afternoon.

Skies clear out early Thursday and Friday looks mostly clear with above normal temperatures. Saturday afternoon and early Sunday another weak low pressure trough will pass through with a chance of showers over the foothills and mountains (see map below).  Temperatures will cool back to near or a little below normal.

Early next week looks mostly sunny with temperatures a few degrees above normal.

This morning a low pressure area and frontal system are moving into western Canada and the Pacific Northwest.  The southern end of this system will bring some mid and high clouds to Northern California.  Temperatures will be near normal with light winds.

Sunday through Tuesday high pressure will be over California with frontal systems passing by to our north.  Skies will be partly to mostly sunny with a few clouds at times.  Temperatures will slowly warm and by Tuesday will be 10 to 15 degrees above normal.  Winds will be light.  

Wednesday the high weakens and this allows the jetstream to move southward over the north end of the state.  A weak low pressure trough will move through late Wednesday followed by another system Friday afternoon and Saturday (see map below).  The Wednesday system will bring light showers to the foothills and mountains with the chance of an isolated shower in the valley, the Friday/Saturday system will be a little stronger with a better chance of rain in the valley.

This morning's satellite picture (below) showa a low pressure area and frontal system moving into the Pacific Northwest with the southern end brushing Northern California.  Today the areas from Redding northward will be partly cloudy to cloudy with a few light showers on the north coast and near the Oregon border.  The areas south of Redding will be partly to mostly sunny.  Temperatures will be near normal.  Light to moderate southwest to northwest winds will occur this afternoon.

Thursday through at least the mid part of next week we will be under a weather pattern like the one shown on the map below.  High pressure will be along and over the California coast.  However a fairly strong jetstream will run across the Pacific and enter the west coast just to our north.   This means the north state will be see some clouds as fronts ride by to our north, but mostly sunny otherwise.  The cloudy days look like Saturday and again next Tuesday.  Temperatures will be a few degree above normal and winds will be light.

A weak upper level low pressure area will move across Central California today.  This system will bring some clouds to our area with scattered light showers over the foothills and mountains with a chance of an isolated shower in the valley.  Light to moderate south to southeast winds will occur. 

Tuesday high pressure will begin pushing northward over the west coast.   We will see partly to mostly sunny skies and near normal temperatures and light winds.  

Wednesday a frontal system will be riding over the high and passing by to our north.  This system will bring clouds to the north end of the state with isolated showers possible near the Oregon border.  The rest of the north state will see partly to mostly sunny skies with temperatures normal or a few degrees above. 

Thursday through early next week the high pressure ridge will be over the west coast (see map below).  Skies will be clear with daytime temperatures 10 to 15 degrees above normal by the weekend,

Thunderstorms flared up yesterday over the Sierras from Tahoe southward with isolated activity also over the Trinity county area.  The residual clouds from these storms are over Northern California this morning.  There is also a very weak upper level low pressure area over the Pacific Northwest dropping southeastward.  The weak low combined with the moisture over the north state will trigger afternoon and evening showers and thunderstorms mainly over the foothills and mountains today and Sunday .  While the valley will be partly to mostly sunny there could be an stray shower or thunderstorm move across the north end this afternoon and Sunday afternoon.  Light to moderate south winds are expected in the afternoon today and Sunday.

Monday another weak upper level low pressure area will move across the north state (see map below).  This system will bring another chance of showers and thunderstorms over the foothills and mountains.  

Tuesday a high pressure ridge will begin to push northward over the west coast.  Tuesday and Wednesday we will see a few clouds at times from fronts moving by to our north.  Temperatures will be near normal.  

Thursday through the weekend look mostly clear with above normal temperatures.  Gusty north winds will occur Thursday through midday Friday.

This morning's satellite picture (below) shows the closed or cut-off low pressure area off the coast and dropping southward.  The low will move inland over Southern California late Friday.  This is a weak system without much moisture.  We will see a few clouds at times from this low today through Friday.  Thursday and Friday there could be some isolated afternoon and evening showers or thunderstorms over the Sierras from Mt lassen southward.  Temperatures will continue above normal.  Gusty north winds will occur in some areas Thursday.  

Friday and Saturday look partly to mostly sunny with afternoon and evening clouds over the mountains.  Temperatures will be slightly above normal with light winds.  

Sunday the jetstream will begin split and break under the high pressure ridge that is off the coast (see map below).  The weaker southern branch of the jetstream will push a low pressure area toward Northern California late Sunday and Monday.  This system will bring scattered light showers to the north state Monday.  

Another low pressure area could break under the high and reach the coast Wednesday and Thursday.

High pressure is off the coast.  Today through Wednesday Northern California will see sunny skies, above normal temperatures and occasional gusty north winds. 

It still looks like a low pressure area will break off the jetstream and form a closed low pressure area.  However, now it looks like the low will be further off the coast as it drops southward (see map below).  Northern California will see some clouds with isolated light showers over the higher elevations Thursday and Friday.  The valley will be partly to mostly sunny with temperatures continuing above normal.

Late Saturday through early Monday another closed or cut off type low will move across the north state with scattered light showers. 

It seems like we are seeing a lot of these cutoff or closed low dropping south along the coast this spring.

High pressure is just off the west coast.  Today and Sunday the valley will be mostly sunny.  There will be some afternoon clouds over the higher elevations with isolated showers or thunderstorms along and east of the Sierra Cascade Crest.  Temperatures will be a few degrees above normal.  Winds will be light today with increasing north winds Sunday.

Monday through Wednesday the north state will be sunny.  Temperatures will continue above normal.  Locally gusty north winds will occur Monday and Tuesday.

Things begin to get complicated by midweek.  Tuesday a weak low pressure area will break off the jetstream and form a closed or "cutoff" low pressure area which will be nearing the Northern California coast late Wednesday (see map below).  Since these lows do not have a strong steering wind, they tend to move slowly and erratically.   At this time it looks like this low will move very very slowly eastward and will affect our weather through late Friday or early Saturday.  During this time we will see partly sunny to partly cloudy conditions with showers or thunderstorms mainly over the foothills and mountains with isolated activity possible in the valley.  Temperatures will be be near normal.

This morning's satellite picture (below) shows the low pressure area moving inland over Southern California.  This low continues to have quite a bit of moisture and clouds with it.  Yesterday it pushed the clouds northward to about Redding and today the cloudiness will be about as far north as the Bay Area and Lake Tahoe. the rest of Northern California will have sunny skies today with temperatures a little above normal.  Gusty north winds will occur in some areas.  

Thursday through the start of next week a high pressure ridge will be along and just off the coast (see map below).   The north state will be partly to mostly sunny with some clouds at times from fronts riding by to our north and east.  Temperatures will be 8 to 12 degrees above normal with periods of gusty north winds.  

The models still show a weak low pressure area moving across Northern California next Wednesday or Thursday.

The low pressure area off the Northern California coast is beginning to move slowly southward and will move inland over Southern California by midweek.  Today Northern California will have partly cloudy skies with scattered showers mainly over the foothills and mountains.  The valley should be partly to mostly sunny by afternoon.  

Tuesday there will be be clouds and a few showers along and east of the Sierra Cascade Crest with partly to mostly sunny skies elsewhere.  Temperatures will be warming but still below normal.  Gusty north winds will move into the area.  

Wednesday through the weekend a high pressure ridge will be along and off the west coast (see map below). Skies will be mostly clear.  Temperatures will be 8 to 12 degrees above normal.  Gusty north winds will continue through Thursday afternoon.  

The ridge looks like it will pull back to the west Monday and this could allow another low pressure area to move across the north state next Tuesday.
