Make sure you're ready for another day of severe heat before you head out the door. Skies have stayed clear overnight, and are expected to be sunny to mostly sunny today. A Heat Advisory is still in effect for the Northern end of the valley, and portions of the Northern Mountains through 8pm tonight. Temperatures have dipped into the low to mid 70's in the valley this morning, and into the 50's to low 60's in the mountains overnight. Winds are starting out out of the East to 10mph this morning, but are expected to become out of the South to 10mph this afternoon. Humidity will dip to the 10 to 25 percent range again this afternoon, and the dry conditions paired with hot temperatures will drive elevated fire danger this afternoon. High temperatures are projected to top out in the 104 to 109 degree range in the valley this afternoon, and in the mid 90's to low triple digits in the mountains later today. Some clouds will return tonight, and then more clouds are expected to fill into the region tomorrow.
A very modest but welcome cooling trend is on the way in your late week, and weekend forecast. Cloudy to partly cloudy skies, and the potential for thunderstorms will be returning through the day on Friday. High temperatures are expected to top out in the high 90's to low triple digits on Friday afternoon, while mountain areas mostly top out in the low to mid 90's. Temperatures will stay in the same range through the weekend, and the potential for thunderstorms will continue. The best chance for thunderstorms and showers will be in the Sierra, but isolated thunderstorm activity cannot be ruled out for the valley.
Skies will clear out again for the start of next week, and temperatures will heat back up into the triple digits for the entire valley by Tuesday. The warming trend will then continue through at least the middle of next week, with severe heat expected by Wednesday. Showers and thunderstorms will then be possible again towards the end of next week, but models are still unclear on how widespread that threat will be.
