Not much change in the large scale weather pattern for the next week.   A large high pressure area will stay east of our area.  Temperatures will slowly warm and by the weekend be 8 to 10 degrees above normal.  Sunday and early next week it looks like another surge of monsoonal moisture will be pulled northward and this could trigger mountain thunderstorms.   Afternoon south to southwest winds will continue.

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 that the high pressure area is still east of our area and that it has pulled monsoonal moisture northward.  The majority of this moisture is staying east of the Sierra Cascade Crest.  There could be isolated thunderstorms today in Lassen and eastern Plumas counties.  Temperatures today will be about like yesterday or slightly cooler.  Increasing south to southwest winds will occur in the afternoon.  

The high will stay to our east for the next week (see map below), with southwest flow aloft.  The inland areas of Northern California will be clear with daytime temperatures 3 to 7 degrees above normal.  South to southwest afternoon winds will continue.

Normal high/ low temperatures for July12-July19 (high/low)   Redding 98/67, Chico 97/61, Quincy 90/45, Chester 85/46, Susanville 90/51, Grass Valley 88/57, Weaverville 95/50, Mt. Shasta 85/51, Yreka 92/53, Alturas 89/45


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 area that was over our area has moved a little eastward.  This puts Northern California on the westside of the high.  The winds aloft will now be south to southwest (see map below).   This means subtropical or monsoonal moisture can be pulled northward and cause thunderstorms.  When the steering winds are southwest the thunderstorms will be along the California/Nevada border but when the winds are south the activity will more over our area.

Today through next week Temperatures will be 3 to 5 degrees above normal.  There will be a chance of afternoon and evening thunderstorms over the higher elevations Sunday and Monday again late next week and weekend.  South to southwest afternoon winds will continue.
