The threat of thunderstorms with little to no rainfall over dry fuels is resulting in high fire danger in your Monday forecast. A Red Flag Warning for high fire danger is set to stay in effect through 11AM in the valley, and through 11PM in the foothills and mountains today. The best chance for thunderstorms in the valley will be in the morning, but the threat of thunderstorms will linger into tonight for higher elevations. The most activity is expected in areas of the Sierra, the Sierra Foothills, and the Southern Cascades today. The Northern Mountains will also have a decent chance for thunderstorm activity into tonight. The Red Flag Warning is currently in place across our entire region for the start of the day. Air quality will also continue to be very impacted today, so you should try to limit your time outdoors as much as possible.

Cloudy skies are brushing from south to north across our region this morning, and we have had limited showers moving through. Some thundersotrm activity was abserved along the western edge of Tehama County between midnight and 2AM. The potential for thunderstorms will linger in the valley through the morning, but does not look likely after that. Thunderstorm activity will continue to be possible through tonight in the foothills and mountains. Temperatures are starting out in the 70's in the valley, in the 70's to low 80's in the foothills, and in the 50's to 60's in the mountains this morning. Surface winds are mostly out of the east early today, with mid valley areas seeing winds out of the southeast, and northern zones seeing winds up to 10mph out of the northeast. South winds to 10mph, with gusts up to around 20mph are expected this afternoon. Humidity is expected to dip into the teens to around 30 percent later today, so conditions will still be very dry. Valley areas are projected to top out in the mid to high 90's, while foothill and mountain areas end up in the 80's to mid 90's this afternoon. Fire danger will be in the high to extreme range today with the threat of thunderstorms continuing into tonight in the mountains. The other big impact will be the smoke on our air quality, with most areas expected to stay in the unhealthy range today.

Air quality is expected to be the biggest factor in your forecast on Tuesday, and will continue to be until the wildfires in our region are put out. Temperatures will be a degree or two cooler on Tuesday compared to today, and will then stay in that range through Wednesday. Our region will see a very slight threat of thunderstorms in areas closest to the Nevada border on Tuesday, but the rest of our area is not expecting active weather. A modest uptick in temperatures is currently forecasted for the end of this week, and we'll see a return to high 90's to low triple digits by Friday in the valley. We'll be staying hot on Saturday, but a modest cooling trend is currently expected to take hold on Sunday, and that should knock valley locatoins back into the mid to high 90's on Sunday into Monday.

Please make sure to use extra caution with the elevated fire danger across our region, and limit your time outdoors as long as we see these issues with air quality persist.
