You may want to get that umbrella handy as you're getting ready to head out the door this morning! We have cloudy skies overhead, and light scattered showers have developed across northern California. Most of the showers and expected early to mid day today, with scattered showers and the potential for mountain thunderstorms lingering this afternoon and tonight. We'll have partly to mostly cloudy skies through your Tuesday. High pressure lingers off to our east, and we have low pressure to our south today. Another weak area of low pressure will track across our region today, and will help to usher monsoonal moisture through our region. The high pressure to our east is also helping to usher in the moisture, and that's what's providing the cloud cover and potential for wet weather. There is still a decent chance for thunderstorms in the northern Sierra and southern Cascades today, but that threat is looking less likely for the valley compared to what previous models were showing. Temperatures are starting out in the 60's to 70's in the valley and foothills, while mountain areas have mostly dipped into the upper 50's to mid 60's overnight. Winds will end up out of variable directions through the day, and are mostly expected to be out of the southwest in the foothills and Sierra. Valley areas will likely see north winds this afternoon as the weak trough tracks through. High temperatures are expected to end up much cooler for your Tuesday. We'll top out in the mid 80's to lower 90's across most of the valley, while foothill and mountain areas range from the mid 70's to mid 80's this afternoon. Humidity will only dip into the 24 to 34 percent range later today. Overall, this is good news for our fire danger, and we'll end up in the moderate range today. The big concern is if we end up with thunderstorm activity over the Dixie Fire, which could be accompanied by locally stronger winds, and lightning.
Valley areas will start to clear out on Wednesday, but clouds and the potential for active weather will linger in our higher elevations over the next couple of days. The best chance for active weather will end up in the northern Sierra for the afternoon and evening hours on Wednesday and Thursday, but there will also be a chance for some active weather in the Northern Mountains. Temperatures will end up back in the triple digits in the valley on Wednesday afternoon, while foothill and mountain areas to out in the 80's to 90's. Temperatures are projected to continue to heat up through Friday, with valley areas projected to top out in the 105 to 109 degree range. Most foothill and mountain areas will climb into the 90's late this week.
We'll start to have more clouds filling into northern California through this weekend, and can expect a decent dip in high temperatures compared to Friday. We'll also have the potential for showers and thunderstorms in the Sierra and Cascades both days this weekend. Valley areas can expect high temperatures in the upper 90's to lower triple digits from Saturday through Monday, while foothill and mountain areas range from the 80's to 90's. We'll then dry out again early next week, but aren't expected to heat up much compared to the weekend.
