Severe heat is ramping up across Northern California this week

Severe heat and the potential for mountain thunderstorms are on the way for your Tuesday

Posted: Jul 24, 2018 6:48 AM

Make sure you're dressed for hotter temperatures this afternoon, and stay hydrated as you go about your day. Even hotter temperatures are expected across Northern California today, and the threat of thunderstorms will be lingering in the mountains this afternoon. The best chance for active weather will be in Siskiyou County, but we cannot rule out an isolated thunderstorm popping up in the Sierra this afternoon. Rising temperatures have prompted a Heat Advisory to go into effect today at noon, and that is currently projected to stay in place through 11pm Thursday night. There is a decent possibility that advisory could be extended further towards your weekend.

Skies are starting out mostly clear this morning, and will stay mostly sunny through the day. Temperatures are in the low to mid 70's in the valley to start your day, and mountain areas have dipped into the 50's to 60's overnight. Winds are starting out of the Northeast to 10mph again this morning, but are expected to shift to mostly out of the South to 10mph this afternoon. Humidity will dip to as low as 15 percent later today, so that is not expected to change much from yesterday. High temperatures are projected to climb into the 104 to 109 degree range in the valley today, with mid 90's to low triple digits projected for the mountains this afternoon.

The latest projections are showing temperatures climbing by a degree or two over the next couple of days. Looks like the valley will end up in the 106 to 111 degree range by Thursday. Temperatures are expected to stay the same on Friday, and then possibly get a little hotter heading into your weekend.
