The heat continues in your Thursday forecast, and even hotter weather is on the way in your forecast. Skies are clear this morning, but some clouds are expected to return this afternoon. There is a chance for thunderstorms returning to the Sierra this afternoon, but the biggest threat of active weather will be to our South and East. Fire danger will be high again today and the potential for mountain thunderstorms adds an extra concern for fire danger this afternoon. Lightning could spark new fires where they occur. Temperatures are starting out in the 60's to 70's in the valley this morning, and mountain areas have dipped into the 40's to 50's overnight. Winds are out of the Northeast to around 10mph this morning, but will become out of the South to 10mph this afternoon. Humidity has not recovered well overnight, and will end up in the 10 to 20 percent range this afternoon. The very dry conditions are also cause for fire danger concern today. High temperatures are projected to top out in the 100 to 105 degree range in the valley and in the 90 to 96 degree range in the mountains.
Conditions will be very similar across Northern California on Friday, but the heat will ramp up this weekend. Hotter temperatures on the way have prompted the National Weather Service out of Sacramento to issue an Excessive Heat Watch from 11am on Saturday through 11pm on Sunday. High tempertures in the valley are projected to end up in the 103 to 108 degree range on Saturday and in the 104 to 110 degree range on Sunday. Mountain areas will end up in the 90's both days this weekend. The heat will be dangerous and you're encouraged to use caution in the heat. Make sure you stay hydrated, dress for the hotter temperatures, plan your outdoor activities for earlier in the day and keep a close eye on sensative groups. The groups most impacted by the heat are the very young, the elderly, and your pets. Temperatures will start to drop on Monday, but we'll still be above average for the start of next week. Temperatures are expected to dip back into the double digits towards the middle of next week.
