Storm Tracker Forecast: Hot with more mountain thunderstorms Sunday

Temperatures will stay around or slightly above average, and the potential for mountain thunderstorms will linger on Sunday. Sunny skies, warm temperatures, and dry conditions are on the way for your first work week of August.

Temperatures ended up a few degrees cooler, and thunderstorms returned to some of our higher elevations on Saturday. We still have a ridge of high pressure parked off to our east, and that is continuing to draw monsoonal moisture north into northern California today. That moisture tracking through our region has caused the instability that kicked off thunderstorms in areas of Shasta, Lassen, and Siskiyou Counties. There is still a threat of thunderstorms also in Trinity County and Modoc County through this evening. A Red Flag Warning for high fire danger will remain in effect through 10pm Saturday in western Siskiyou County due to the threat of thunderstorms over dry fuels in the area. The threat of thunderstorms will diminish late this evening, but will return to some of our mountain areas on Sunday. We've had sunny to mostly sunny skies across the valley on Saturday, and our air quality has greatly improved compared to Friday as south winds have developed. High temperatures ended up in the mid 90's to lower triple digits in the valley, and 80's to 90's in the foothills and mountains. Winds are mostly out of the south from 10 to 20mph this evening in the valley, and southwest winds have been observed in areas around the Dixie Fire.

Sunday will be just about as hot as Saturday was, and we'll have the potential for mountain showers and thunderstorms in the afternoon and evening hours. The best chance for thunderstorms will be from Plumas County through Modoc County, but portions of Shasta and Siskiyou Counties will also have the potential for active weather. Low pressure tracking towards the West Coast will nudge the high pressure off to our east further from our region on Monday, and that will push the potential for thunderstorms out of our area. Models are showing a fairly average first week of August ahead in our forecast. Valley temperatures will range from the mid 90's to lower triple digits, while mountain and foothill areas top out in the 80's to 90's. Temperatures will start to trend downward later in the week and next weekend as low pressure tracks through to our north. This will also bring a chance for showers to areas closest to the Oregon border Saturday and Sunday of your extended forecast, but the rest of our region is expected to stay dry through the extended forecast. There does not appear to be any big wind events on the horizon, which is good news for our fire danger this week.

Thankfully, the wind is cooperating much better today in northern California. Our weather is still quite hot for this time of year and very dry. There is plenty of haze and smoke from the Fawn Fire overhead, and it isn't leaving yet.
