The heat is on today and we're only going to get hotter over the next few days. A dominant ridge of high pressure off to our East will be the main feature in your forecast this week, and we also have high pressure off the coast in the Pacific. Skies are clear this morning and will stay sunny through the day. Temperatures are starting out very warm. Valley and foothill areas are mostly starting out in the high 60's to mid 70's, and mountain areas are in the high 40's to 50's this morning. Winds are out of the Northeast to around 8mph, but will shift this afternoon. Valley areas can expect 10mph winds out of the South later this afternoon. Humidity is starting out below 50 percent in most areas this morning, and will dip into the teens this afternoon. High temperatures are projected to end up in the 100 to 105 degree range in the valley, while foothill and Sierra locations end up in the low to mid 90's. Portions of the Northern Mountains may end up in the high 90's this afternoon.
This pattern of hot and dry conditions is expected to intensify over the next few days, with even hotter temperatures on the horizon for the middle of this week. Temperatures are projected to be a degree or two warmer than Monday on Tuesday, and will then end up 1 to 5 degrees warmer than Monday on Wednesday. The biggest jump in temperatures is expected in the north end of the valley mid week. Some mountain areas will also be getting close to the century mark on Wednesday. Low pressure off the coast of Southern California may kick up enough moisture to result in mountain thunderstorm activity along the Sierra crest on Wednesday and Thursday. The latest projections leave our region with a much better chance for this active weather on Thursday afternoon/evening. We'll also see a very modest drop in temperatures on Thursday compared to Wednesday. Valley areas are projected to dip back into the high 90's to around 104 degrees on Thursday afternoon, while foothilll and mountain areas dip back into the low 90's. That subtle dip in temperatures is not expected to last long, and we'll be heating back into the triple digits for the entire valley this weekend.
Valley areas are expected to be sunny, with high temperatures in the 100 to 105 degree range through your weekend, while foothill and mountian areas top out in the low to mid 90's. This is going to be a very hot week across our region, with little recovery from the heat overnight. You're encouraged to take precautions against heat related illness. Make sure you're drinking plenty of water, dressing for the heat, and avoiding outdoor activities during the peak heat of the day if you can. Fire danger will also be a concern as conditions will be very dry.
