Get ready for a HOT day on the way in your Thursday forecast. High pressure off the coast in the Pacific is the dominant feature in our forecast today, and will continue to give us similar conditions to what we had outside on Wednesday. Skies are clear for the start of your Thursday, and we'll stay sunny to mostly sunny today. Temperatures are very warm this morning and will get downright hot this afternoon. Valley and foothill areas are starting out in the 50's to 60's this morning, while mountain areas have dipped into the 30's to 40's overnight. Winds are still mostly light and out of the north this morning, but will shift to become out of the south to 10mph this afternoon. High temperatures are projected to end up in the mid 90's in the valley, upper 70's to upper 80's in the foothills, and mid 70's to upper 80's in our mountain zones this afternoon. The heat is a big concern today, and you'll need to stay aware of the potential for heat related illness through the day. Make sure you're drinking plenty of water, dressed for the hotter temperatures, and try to avoid being active outside in the peak heat of the day.
Low pressure dropping down from the Pacific Northwest will bring a modest cooling trend into our forecast from Friday into Saturday, but it will also bring the potential for light showers and thunderstorms to our region. The potential for thunderstorms is a major concern for fire danger in our region, as lightning sparked fires will be possible. Most of the active weather is expected to stay in our higher elevations on Friday and Saturday, but there will be a slight chance for some active weather sagging into the valley. High temperatures will dip back into the upper 80's to lower 90's in the valley on Friday, and then top out in the mid 80's on Saturday. Foothill and mountain areas will top out in the 70's to lower 80's on Friday, and will then only climb into the 60's to 70's on Saturday afternoon. That area of low pressure will then track to our south into central California on Sunday, and out high temperatures will rebound by a few degrees. Temperatures will climb back into the 80's to lower 90's in the valley on Sunday afternoon, while foothill and mountain areas end up back in the 70's to mid 80's as high pressure builds back into our region.
A weak wet system brushing through the Pacific Northwest will bring another modest cooling trend into our forecast next week, with valley areas dropping from the upper 80's to low 90's on Monday into the mid 80's by Wednesday. Most mountain and foothill areas can expect high temperatures in the 60's to 70's next week. There will be a slight chance for showers as far south as Shasta County next Tuesday and Wednesday.
