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 weak upper level low pressure area off the coast.  This low is moving slowly eastward and will pass across Northern California late tonight and Thursday.  The low will trigger a few thunderstom over the higher elevations of the north state later today and Thursday.  These is a chance of a thunderstorm in the valley north or Red Bluff.  Temperatures today will be a few degrees above normal.  Gusty south to southwest winds will occur in some areas this afternoon.

Friday we will have sunny skies with above normal temperatures.  Saturday and Sunday another weak low pressure area will be off the coast (see map below).  This system won't have much moisture but could cause isolated thunderstorms over the higher elevations. Temperatures Friday through the weekend will be normal to a few degrees below normal.  Winds will south to southwest in the afternoon.

Models indicate another weak upper level low pressure trough brushing the north state Monday and Tuesday.  This system could trigger isolated thunderstorms north of Redding.
