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 off shore low pressure trough will move across Northern California today. Skies will become partly cloudy with a chance of showers or thunderstorms over the mountains and in the valley north of Red Bluff. Temperatures will continue below normal and gusty southwest to northwest winds will occur in the afternoon.
Thursday look partly to mostly sunny. Temperatures will be warmer but still below normal. Light to moderate west to northwest winds are expected.
Friday through Tuesday Northern California will be squeezed between two weather systems. Friday another low pressure trough will be approaching the coast. However, the high pressure ridge to our east will be pushing back to the west. Friday the off shore low will send a band of clouds across the north state with isolated light showers along the north coast and the areas north of Redding. Temperatures will continue below normal. Saturday and Sunday the areas along the coast and over Trinity and Western Siskiyou counties will be partly cloudy with normal or slightly below normal temperatures. The valley and Sierra Cascade area will be sunny with above normal temperatures. South winds will increase in the afternoons.
Monday afternoon and Tuesday the high pressure ridge wins and the off shore low will weaken and move northeastward as the high pressure area pushes back towards our area (see map below). The northwest corner of the state will see a few clouds, but the rest of the north state will be sunny with above normal temperatures.
Wednesday through the end of the week the high will dominate our weather with sunny skies and above normal temperatures.
