Below average temperatures, dry weather, impacted air quality, and breezy south and southwest winds are on tap in your Tuesday forecast. Low pressure just off the coast of northern California and Oregon will keep our temperatures cooler on Tuesday. A decent onshore flow and influence from the Delta Breeze will both play a role in our below average temperatures. Winds are mostly light and out of the northeast this this morning, but will shift to become out of the south and southwest across northern California this afternoon depending on where you are. Valley areas will mostly have south winds, while our foothill and mountain areas mostly have winds out of the southwest. A Red Flag Warning for high fire danger will be in effect from 2pm through 8pm in Modoc County Tuesday due to low humidity and gusty southwest winds over dry fuels. Air quality has improved compared to early Monday as the south winds yesterday helped to clear a lot of the wildfire smoke impacts back into areas closest to or north of our active fires. Valley and foothill areas have air quality in the moderate to unhealthy for sensitive groups range to start your Tuesday, while air quality is unhealthy to hazardous in areas closest to the Dixie and Monument Fires. Skies are moslty clear of clouds early today, and we'll stay mostly sunny through the day. Temperatures are starting out in the 50's to 60's in the valley and foothills, while mountain areas have dipped into the 30's to 40's ovenright. Humidity will dip into the 12 to 28 percent range this afternoon, which is a little drier than Monday. High temperatures will top out in the 80's to lower 90's in the valley, and mid 70's to mid 80's in our foothill and mountain areas this afternoon. Fire danger will mostly be in the moderate range this afternoon, but locally gusty southwest winds in areas around the eastern zones of the Dixie Fire and in Modoc County will mean moderate to high fire danger in those areas.

Low pressure will start to swing across southern Oregon and northern California on Wednesday. This will keep our temperatures and winds similar to Tuesday, and result in more clouds brushing across our region through the day on Wednesday. The low will track to our east on Thursday and high pressure will build into the southwest from the Pacific late this week. This will result in a moderate warming trend and the return of north winds in your late week forecast. Valley areas can expect high temperatures in the mid 90's on Thursday, and upper 90's to lower triple digits on Friday afternoon. Foothill and mountain areas will have high temperatures back in the upper 80's to lower 90's by the end of this week. Overnight low temperatures will mostly dip into the 60's to lower 70's for the valley and foothills towards the end of this week, and mountain areas will fall into the 40's to 50's in the overnight hours.

High pressure to our south will continue to keep slightly above average temperatures, sunny skies, and dry conditions across our region through this weekend. Valley areas will have lows in the 60's to lower 70's and highs in the upper 90's to lower triple digits both Saturday and Sunday. Foothill areas will have low temperatures in the 60's to 70's, and high temperatures in the 80's to mid 90's through the weekend. Mountain areas will dip into the 40's to 50's overnight and top out in the 80's to mid 90's this weekend. The latest models are showing high pressure retrograding back out into the Pacific and low pressure tracking into the Pacific Northwest early next week. This will result in temperatures dipping back to just below average and our conditions staying dry through the middle of next week.

The fog tucked us in last night, leaving for some surreal driving conditions on the roads. We see the potential for a repeat situation this evening for the valley.
