Get ready for a very hot and dry start to your work week as high pressure off to our east continues to dominate our forecast Monday. Locally stronger winds in our northern zones has prompted a Red Flag Warning for high fire danger in Modoc County from 2pm through 10pm Monday. The hot, dry, and windy conditions will be a big concern for fire danger there today, and winds will be a bit stronger across most of northern California on Monday afternoon. We're also going to have very impacted air quality across northern California today, and it will get worse in the valley tonight. Air quality is in the hazardous range in areas of Trinity County, Plumas County, and western Shasta County. Very unhealthy air quality is being reported in the foothills, and we're ranging from unhealthy for sensitive groups to unhealthy across most valley areas to start your Monday. Skies are clear to start the day, and we'll stay sunny this afternoon. Smoke will still blanket most of our region and could help to keep some areas from reaching their projected high temperatures this afternoon. Temperatures are starting out in the 70's in the valley and foothills, and most mountain areas are in the 50's to 60's this morning. Winds are starting out of the northeast to 10mph this morning, and will end up out of variable directions this afternoon. Our northern zones will have north winds, our higher elevations will mostly have west winds, and the mid valley will have south winds Monday afternoon. Humidity will dip into the 7 to 20 percent range later today. High temperatures are projected to end up in the 102 to 107 degree range in the valley, and 90's in the foothills and mountains this afternoon.
Low pressure tracking through the Pacific Northwest will bring a welcome drop in our temperatures on Tuesday, and then stronger north winds into our forecast from Tuesday evening through Wednesday night as is drops south to our east. That increase in wind speeds will bring high fire danger to our forecast through the middle of this week. A Fire Weather Watch has been issued for the valley, foothills, and most of our mountain areas from Tuesday evening through Wednesday evening. The strongest winds are expected early to mid day on Wednesday. Sustained winds to 30mph out of the north will be possible, and we could have gusts up to around 40mph. Temperatures will top out in the mid 90's in the valley on Tuesday and Wednesday, while most foothill and mountain areas end up in the 80's both Tuesday and Wednesday. Low pressure will track further to our east on Thursday, and our high temperatures will rebound back up to around average for this time of year late in our work week. That means mid to high 90's in the valley, and 80's to 90's in the foothills and mountains.
A welcome drop in temperatures is expected to arrive this weekend as low pressure tracks through to our north. Valley areas will start out in the 60's and end up in the low to mid 90's this weekend. High temperatures in the foothills and mountains are only projected to end up in the upper 70's to mid 80's both days this weekend. The cooler conditions are certainly a welcome sight in our extended forecast, but we could also be dealing with another round of gusty north winds early next week. Dry weather is projected to persist across your entire extended forecast.
