High pressure will be over our area Thursday through the weekend.  Skies will be clear and temperatures will be above normal.   Gusty north winds will occur Thursday and Friday with light winds on the weekend.  

Monday another low pressure trough moves through the Pacific Northwest (see map below).  This system will also bring a few light mountain showers to the north state.   After this system passes high pressure will rebuild over our area.

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 that moved across Northern California yesterday is now over the Nevada.  The low will linger there today.  Later today and early Sunday another low pressure area will drop southward from Canada and merge with the low over Nevada. The combined low pressure areas will then move eastward.   Today through midday Sunday there will be a few light showers over the foothills and mountains with the chance of a stray shower over the north end of the valley.  Snow levels will be near 5000 feet.  West to northwest winds today and then gusty north winds Sunday afternoon through midday Monday.  

Skies will be clearing out Sunday evening and temperatures will be cold in the wind sheltered areas. Monday through next weekend we will be under a weather pattern like the one shown on the map below.   The jetstream will run across the Pacific and enter the U.S. just north of California.  This means that as frontal systems pass by to the north we will see a few clouds and maybe a few showers near the Oregon border. One of these weak fronts will move through Tuesday with another late Thursday and Friday.  The days between fronts will be partly to mostly sunny.   Temperatures Tuesday through next weekend will be near normal.

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 over the west but is beginning to weaken.  Today through Wednesday will be mostly sunny with a few high clouds.  Max temperatures will continue above normal and winds will be light.  

Much colder weather is on the way.   Today and most of Thursday will be sunny with above normal temperatures.  Winds will be light today with gusty southwest to northwest winds moving over the area Thursday afternoon and evening.  A cold low pressure area is forming in the Gulf of Alaska and will move eastward and then move across Northern California Friday and early Saturday.  Clouds begin to increase late Thursday.  Thursday night and Friday we will have partly cloudy to cloudy skies with light precipitation over the foothills and mountains and a few light showers in the valley north of Biggs.  Snow levels will be near 5000 feet.  Saturday will be partly cloudy and cool with a few showers over the higher elevations.  Light to moderate west to northwest winds are expected.  

Sunday the low will have moved eastward.  However, another cold low will drop southward from western Canada into Nevada (see map below).  This will keep a few clouds over the north state with scattered light showers over the higher elevations.  Strong and gusty north winds will move into the area Sunday afternoon.

Monday we will see mostly clear skies with a few clouds Tuesday and early Wednesday as a weak frontal system move through.  Temperatures will warm but still be a little below normal.  The gusty north winds will end Monday night.

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 over the west but is beginning to weaken.  Today through Wednesday will be mostly sunny with a few high clouds.  Max temperatures will continue above normal and winds will be light.  

Thursday the high pressure ridge shifts westward as a cold low pressure area develops in the Gulf of Alaska and begins to move southward.  The track the low will take is close to the coast so moisture will be limited.  The cold low pressure trough will pass across Northern California late Thursday and Friday (see map below).  Thursday clouds will begin to increase, temperatures will cool, and gusty southwest to northwest winds are expected in the afternoon.  Late Thursday and Friday light precipitation is expected over the foothills and mountains with a few light showers in the valley north of Chico.  The showers will end Saturday morning as the low continues eastward.

Saturday night high pressure rebuilds along the coast and will hold through the mid part of next week.  Skies will be clear and temperatures will warm back to normal by Monday.  Strong and gusty north winds will occur Sunday through Tuesday.

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 continues just off the west coast and not much change is expected through midweek.  Skies will be mostly clear with a few mid and high clouds Tuesday and Wednesday from a front moving by to the north.  Temperatures will continue 10 to 15 degrees above normal and winds will be light.

Things start to change Thursday the high pressure ridge will shift westward as a cold low pressure area forms along the Canadian coast and drops southward.  This low will move across Northern California Friday and early Saturday (see map  below).  Because this system will be staying so close to the coast it will have limited moisture, but will bring much colder air into the north state.  Thursday will be sunny  changing to partly cloudy to cloudy skies Friday and part of Saturday with scattered showers mainly over the foothills and mountains.  Gusty southwest to northwest winds will precede this low.

The high will weaken a little late Monday and Tuesday (see map below).  There could be a few clouds Tuesday and Wednesday from a frontal system passing by to our north.
