Rising temperatures and poor air quality will be the big issues ahead for your Tuesday. Air quality seems to be starting out in worse shape than Monday morning, with most areas showing air quality in the unhealthy for sensitive groups to unhealthy range early today. Limiting outdoor activities will be a good idea for today. Visibility is also lower to start off our Tuesday, with areas surrounding the Carr Fire showing around 3 miles of visibility to start the day. Temperatures have dipped into the mid to high 60's in the valley overnight, and mountain areas are starting out in the low 50's to low 60's this morning. Winds are out of the North and mostly light this morning, but are expected to pick up to around 10mph out of the South this afternoon. Humidity could dip to below 10 percent in the Northern end of the valley, while the remainder of Northern California is projected to drop into the 15 to 25 percent range this afternoon. High temperatures are expected to become hotter today. Valley areas will more than likely top out in the 99 to 107 degree range later today, while mountain areas end up in the low to mid 90's.
High pressure will continue to build across the Southwest and act as a blocking mechanism to keep wet and cooler weather at bay. Temperatures will stay in the 100 to 107 degree range in the valley on Wednesday. Thursday will likely be just as hot, if not a degree cooler than Wednesday. Skies are expected to stay clear of clouds, but haze will more than likely continue to impact sky conditions over Northern California through the end of the week. There is a modest but welcome drop in temperatures projected for Friday. Valley areas are currently projected to top out in the mid 90's to low triple digits on Friday afternoon. South winds will pick up late this week, and that could help to clear out some of the haze that's become stagnant in our region.
Models are currently split on whether a modest drop in temperatures or another warming trend are on the way for next week. At the moment, the warming trend looks more likely. That could put temperatures back in the 99 to 105 degree range in the valley early next week. That is subject to change if we do see any more shifts in the longer range models.
