Enjoy the mild heat while it lingers today as we'll be heating back up through your weekend. We'll have temperatures slightly below to around average on Friday afternoon, and our fire danger will remain elevated today. A Red Flag Warning for high fire danger is set to be in effect from 3pm through 8pm Friday in Modoc County due to dry fuels, low humidity, and southwest wind gusts up to around 30mph. While we do not have any other Red Flag Warnings or Fire Weather Watches set to go into effect that does not mean our fire danger isn't a concern today. Lighter south winds and less influence from the onshore flow to our south will result in lower relative humidity this afternoon, and overall a dryer airmass than Thursday. We still have high pressure off to our east keeping us dry and very warm, but low pressure tracking into the Pacific Northwest will continue to provide a modest cooling influence as the Delta Breeze continues to keep our high temperatures in check on Friday. We have clear skies overhead this morning, and will continue to be sunny through the day. Air quality will be impacted in areas closest to our most active fires on Friday, with the biggest impacts in areas around the Dixie Fire in Butte and Plumas Counties, and the Beckwourth Complex in Plumas and Lassen Counties. Temperatures are starting out in the 60's in the valley, 50's to 60's in the foothlils, and 40's to 50's in our mountain areas for the start of your Friday. Winds are mostly out of the east or northeast this morning, but will shift to become out of the south or southwest as we head into this afternoon. Humidity is expected to dip into the 13 to 23 percent range Friday afternoon. High temperatures will range from 93 to 99 degrees in the valley, 81 to 90 degrees in the foothills, and in the low 80's to lower 90's in our mountain areas on Friday afternoon.
High pressure will build west through this weekend, and that will result in temperatures heating up by several degrees across northern California. Valley areas will range from the upper 90's to lower triple digits on Saturday and Sunday, while foothill and mountain areas have high temperatures in the 80's to mid 90's. We'll continue to have winds out of the northeast in the overnight hours, and stronger southwest winds in the afternoons through this weekend. There is a chance for light showers and thunderstorms tracking north into the Sierra Sunday and Monday as the high pressure to our east taps into monsoonal moisture from the south. The latest models are split on whether or not to expect active weather in our region, with most models showing the active weather staying to our south and east. Temperatures will stay above average through the middle of next week, and we'll continue to stay mostly dry through your extended forecast. Modest relief from the heat is ahead towards the end of next week, but conditions are projected to stay fairly similar through next weekend.
