Weather Discussion for Saturday April 29, 2017

Normal high and low temperatures for April 24-May 1 (high/low)...Redding 77/50, Chico 75/47, Quincy 66/34, Chester 62/31, Susanville 64/35, Grass Valley 66/42, Weaverville 70/36, Mt. Shasta 63/36, Yreka 66/36, Alturas 62/31

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.

High pressure is just off the west coast.   The high will remain along or over the west coast through Thursday (see map below).   This means a continuation of our spring like weather.   Skies will be mostly sunny with a few high clouds at times.  Temperatures will be above normal and the north valley will probably see it's first 90 degree readings of the year Tuesday and Wednesday.  Periods of gusty north winds will occur.  

Thursday and Friday a weak upper level low pressure area will drop over the north state and this could trigger some mountain showers and thunderstorms.

Normal high and low temperatures for April 24-May 1 (high/low)...Redding 77/50, Chico 75/47, Quincy 66/34, Chester 62/31, Susanville 64/35, Grass Valley 66/42, Weaverville 70/36, Mt. Shasta 63/36, Yreka 66/36, Alturas 62/31

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 shows a lot of clouds and moisture streaming across the Pacific, especially for this time of year.   However, high pressure is slowly building along and off our coast and this will push most of this moisture northward.  

A weak frontal system is now moving across the north state and this will bring light showers or sprinkles to our area today.  Thursday there will be some clouds north of Redding with partly to mostly sunny skies south.   

Friday through at least the mid part of next week high pressure will ge along and off the west coast (see map below).  We will have sunny skies with above normal temperatures and periods of gusty north winds.

Normal high and low temperatures for April 17-April 24 (high/low)...Redding 73/48, Chico 75/46, Quincy 66/33, Chester 59/29, Susanville 63/34, Grass Valley 64/41, Weaverville 69/36, Mt. Shasta 61/36, Yreka 66/36, Alturas 61/29

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.

We continue be in a period of transitioning weather patterns.   High pressure is trying to build off the west coast.  However, the flow across the Pacific is still strong enough to suppress the high's northward push.  This is allowing frontal systems to move inland just to our north with the southern ends moving across Northern California.  

One of these weak systems is moving through the area today and tonight with light rain or showers over the the foothills and mountains and in valley north of Red Bluff.  Sunday skies will be partly cloudy to  partly sunny.  Monday another weak frontal system will bring clouds a light showers to the north state.  This will be followed by another weak system Tuesday.  

Wednesday the high pressure ridge will begin to win the battle and push further northward. (see map  below) Wednesday through the weekend the north state will be partly to mostly sunny.  Temperatures will be normal or a few degrees above.  We will see periods of gusty north winds.

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.

Over the next week we will see high pressure try to push northward over our area, while the flow across the Pacific continues strong and sends frontal systems toward the coast.

This morning's satellite pictures shows a low  pressure area off the coast.  This system is moving eastward and will bring rain and showers to Northern California later today and tonight.   The system has colder air with it and snow levels will drop to near 5000 feet tonight.  Skies will clearing Thursday and Friday should be mostly clear with near normal temperatures. 

The north state will be cloudy to partly cloudy Saturday as a frontal system moves through the Pacific Northwest.  This system will bring a few showers to the north coast and areas near the Oregon border.   Sunday we will have partly to mostly sunny skies.   Monday another frontal system goes by to our north with the southern end brushing our area.(see map below).   Monday and early Tuesday more cloudy skies with light rain or showers north of Redding.   

Wednesday through the end of next week look sunny and mild.

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 weak frontal system moved across the north state last night and brought light showers to some areas.   This morning there are still a few residual showers over the northern mountains but they will be ending during the day.  This afternoon we get a brief break between systems and then Tuesday another low pressure trough and frontal system will move across Northern California.   This system will bring light rain and gusty south winds to our area.  Snow levels will be 5000 to 6000 feet.  Wednesday and Thursday a stronger low pressure trough will move through the north state with light to moderate rainfall and more gusty south winds.   Snow levels will once again be 5000 feet our higher. The precipitation will turn to showers Thursday night and end by midday Friday.

Friday afternoon, Saturday and the first half of Sunday we will see partly cloudy to partly sunny skies and near normal temperatures.   However, by Sunday afternoon another large scale low pressure trough will be developing along the west coast.  The map below shows this pattern.  You can see that the jetstream is running across the Pacific and over Northern California.   It looks like another frontal sysem will bring more rain to the area Sunday night and Monday and then another system around midweek.
