Dangerous heat will persist through early next week, and our fire danger will stay elevated. Modest relief from the heat arrives for the latter half of next week.

The heat ramped up across northern California Saturday afternoon, with high tmeperatures topping out in the 109 to 114 degree range in most valley areas. Temperatures ended up in the upper 90's to triple digits in our foothill and mountain areas Saturday afternoon. The Excessive Heat Warning remains in effect through 9pm Monday for the valley, foothills, and northern Sierra. The Excessive Heat Warning is set to stay in effect in Trinity County throug midnight Sunday, and through 9pm Tuesday for the eastern slopes of the Sierra. We also have a Heat Advisory in effect for portions of Modoc and Siskiyou Counties through 8pm Tuesday. A Red Flag Warning for high fire danger will stay in effect through 10pm Saturday night in Modoc County due to gusty southwest winds and very dry conditions. We have had some very limited showers along the California and Nevada border this evening, but that will wrap up by around 8pm. Thunderstorms have developed to our southeast, but that's not likely to track into our region.

Temperatures will stay very warm overnight, and we'll be almost as hot on Sunday afternoon. Low temperatures in the valley will end up in the mid 70's to lower 80's, and high temperatures will top out in the 107 to 115 degree range. Foothill areas will have low temperatures in the 70's to 80's, and high temperatures will top out in the mid 90's to triple digits on Sunday afternoon. Our mountain areas will mostly dip into the 60's to lower 70's on Sunday morning and will top out in the 90's to triple digits in the afternoon. We'll exclusively have sunny skies, and wind out of the south to around 10mph on Sunday.

Low pressure will approach the West Coast early next week, and some influence from the Delta Breeze can be expected on Monday. This will result in temperatures dropping by a couple of degrees compared to the weekend on Monday. We'll continue to have a modest slide in temperatures through the middle of next week as the high pressure to our east shifts further to the east. Temperatures will still be in the upper 90's to triple digits for the valley through your extended forecast, while our foothill and mountain areas will have high temperatures in the 80's to 90's for the week ahead. There does not appear to be any good chance for wet weather through your extended forecast, but we also do not have any significant wind events to worry about.

Dry conditions, warmer temperatures, and gusty north winds will drive high fire danger and a Red Flag Warning across most of northern California Monday. Winds will diminish and temperatures will warm up on Tuesday. We'll stay dry and heat up later this week. Cooler temperatures then return for your weekend.
