Slightly cooler temperatures, impacted air quality, and active weather is on the way in your Wednesday forecast. We're still sandwiched between high pressure to our East and West, but low pressure passing through to our South will continue to kick up the potential for thunderstorm activity in our region this afternoon and evening. The threat of thunderstorms combined with dry fuels and gusty winds is keeping our fire danger elevated today. A Red Flag Warning has been extended through 9pm tonight for portions of Modoc, Lassen, and Plumas Counties, and an additional Red Flag Warning will go into effect for the remainder of Modoc County, and a large portion of Siskiyou County from 11am this morning through 11pm tonight. Lightning sparked fires will be very possible with the conditions today. There will also be a chance for thunderstorm activity in the northern zones of the valley this afternoon and evening. Temperatures are starting out in the 60's to 70's in the valley, in the 60's in the foothills, and in the 50's to 60's in the mountains this morning. Winds are out of the East up to around 7mph, but will shift to become out of the South up to 15mph this afternoon. The Delta Breeze will play a role in keeping our temperatures from getting as warm as yesterday this afternoon. We'll end up in the low to mid 90's in the mid valley, and in the mid to high 90's in the north valley this afternoon. Foothill areas are expecting to top out in the mid to high 80's today, and mountain areas will end up in the 80's to 90's this afternoon. The best chance for thunderstorms will be this afternoon and evening in higher elevations of the Sierra, Southern Cascades, and the Northern Mountains, with a modest chance for thunderstorm activity in the north valley. Fires burning in our region will continue to result in impacted air quality today. You're advised to limit your time outdoors if you can.

The temperature trend will be very similar on Thursday, but most areas will see a drop of a degree or two in high temperatures. The potential for thunderstorms will start to shift off to the South and East tomorrow, but portions of the Sierra may still see some active weather in the afternoon and evening. Most areas will be sunny to mostly sunny on Thursday. Temperatures will start to rebound on Friday as the low pressure to our South tracks to our East. We'll still have a slight threat of thunderstorms in the Sierra, but the best chance will be to our South through this weekend. The heat will ramp up again as we head into your weekend, with valley high temperatures projected to climb into the high 90's to around 105 degrees. Foothill and Sierra locations can expect high temperatures to top out in the low to mid 90's this weekend, and the Northern Mountains will have high temperatures in the 90's to around 100 degrees. Similar conditions are expected as we head through the start of next week. Enjoy the modest dip in temperatures while it lasts and remember that when thunder roars you should go indoors!

Dry weather, sunny skies, warmer temperatures, and gusty north winds will drive elevated fire danger today. We'll have even stronger winds, but cooler temperatures on Tuesday. Fire danger will remain elevated. There will also be a chance for light showers in the Sierra on Tuesday and Wednesday.
