High fire danger and slightly cooler temperatures are on tap for the end of your work week, and your weekend. A Red Flag Warning is currently in place for portions of Shasta County and Tehama County and is expected to stay in effect through 11pm Saturday night. There is also a Red Flag Warning going into effect at 11am today for the Sierra and Southern Cascades, and that is also projected to stay in place through 11pm Saturday night. Gusty winds and low humidity will be the main driving factors for high fire danger through the weekend. Northwest winds could gusts up to 25mph in areas close to and surrounding the Carr Fire tonight, and tomorrow night. Humidity will likely dip into the 15 to 25 percent range this afternoon, and is not expected to recover much overnight.
There is a modest but welcome cooling trend ahead for your weekend. Temperatures are starting out in the mid to high 60's in the valley this morning, and in the 40's to 50's in the mountains. Winds are out of the North and light this morning, but will pick up to around 10mph out of the South this afternoon. Humidity will likely dip into the 15 to 25 percent range this afternoon. High temperatures will end up in the mid to high 90's in the valley today, and in the mid 80's to mid 90's in the mountains. Air quality will be a big concern again today, and is expected to hover between the moderate to unhealthy range this afternoon. Limiting your time outdoors, and avoiding any strenuous activities in the poor air quality is recommended.
Winds will pick up out of the Northwest tonight, and could gusts to around 25mph. Sustained winds will likely reach speeds up to 15mph in areas surrounding the Carr Fire. Humidity is not expected to recover well tonight, and will more than likely stay below 40 percent in areas where we have active fires. Temperatures will be a few degrees cooler through the weekend, ending up below average for this time of year. Winds will mostly be up to 10mph out of the North on Saturday, but may pick up again on Saturday night. Valley areas will top out in the low to mid 90's through the weekend. Air quality is expected to continue to be an issue over the next several days.
Another warming trend will push valley temperatures back into the mid to high 90's on Monday, and then into the high 90's to triple digits again by Tuesday. Hot and dry weather is expected for next week.
