Storm Tracker Forecast: Cooler with breezy south winds Wednesday

A welcome dip in temperatures, lighter winds, lower fire danger, and improving air quality are all expected in your Wednesday forecast. We'll have similar conditions ahead for your Thursday, but hotter temperatures will return for your Labor Day Weekend.

Posted: Sep 1, 2021 6:05 AM

We have a welcome change of pace ahead in your mid week forecast, but fire danger is still a big concern today. Low pressure centered to our north is the main driving factor in our forecast, and will drive our cooling trend and keep breezy southwest winds across our region Wednesday. Our skies are clear of clouds to start the day, but smoke and haze will linger across our region. Air quality is in the very unhealthy to hazardous range in western Shasta County and Trinity County early Wednesday. The remainder of Shasta County is in the unhealthy range. Plumas County areas closest to Lake Almanor are in the very unhealthy range, but good to moderate air quality is being reported in most valley and foothill areas to start the day. Winds are mostly light and out of the northeast early Wednesday, but we'll have breezy southwest winds developing through the day. Sustained winds in the 10 to 15mph range look likely, while gusts in the 20 to 25mph range will be possible in areas around the Dixie Fire Wednesday afternoon. Humidity is expected to stay a little higher today, but will still dip to below 30 percent across all of northern California through the day. The low humidity, and the breezy southwest winds will keep out fire danger in the moderate to high range Wednesday afternoon. Temperatures are expected to trend much cooler today, and that is also what we're seeing with our low temperatures this morning. Valley and foothill areas are starting out in the 50's to 60's this morning, while mountain areas have dipped into the 30's to lower 50's overnight. High temperatures are projected to top out in the mid 80's to lower 90's this afternoon, while foothill and mountain areas will have high temperatures ranging from the 70's to mid 80's. All around, conditions look much more comfortable, fire danger is not as high, and most of our region will have improved air quality Wednesday.

Thursday is expected to be very similar to Wednesday, but temperatures will end up a degree or two warmer and our winds will not be as strong. The onshore flow will keep humidity slightly higher than early this week. The slightly higher humidity, below average temperatures, and lighter winds are all good news for our Thursday fire danger. This is still all driven by the area of low pressure to our north, but that low pressure will track to the east late this week. As the low pressure exits to the east, high pressure to our southeast will build back into northern California on Friday. This will result in rising temperatures, dry weather, and sunny skies as we head into your weekend. Temperatures will climb back into the low to mid 90's in most valley areas on Friday, and will then end up in the mid 90's to lower triple digits through this weekend. Foothill and mountain areas will climb back into the 80's to lower 90's on Friday, and then 80's to mid 90's through this weekend. Models are showing low pressure off the coast of southern California from Sunday through early next week. This will push monsoonal moisture north towards are region, but models are still split on if that will kick off any active weather in our region. The latest longer range forecast calls for a chance for thunderstorms in the Coastal Range and Shasta County mountains late Monday through Tuesday. There is also a dip in temperatures expected as we head through the middle of next week.

Get out and enjoy this beautiful weather tonight! If you do head out and plan to stay out late, probably bring an extra later to throw on for when the sun sets as temperatures will be cooling off into the low to mid 60s for the valley by midnight and low to mid 40s by tomorrow morning.
