Low pressure moving into Northern California has brought windy, cooler, and active weather back to our region today and that will continue through tonight. Sustained winds out of the South have been up to around 25mph, and gusts have topped 30mph in several cities in the valley. Showers and thunderstorms have been moving through the Coastal Range and Northern Mountains this afternoon, and will become more widespread over the valley and Sierra this evening. Temperatures have been much cooler across our region today. Valley areas topped out in the 70's to low 80's, while foothill and mountain areas ended up in the 60's to 70's.
The threat of showers will linger over Northern California on Saturday, and temperatures will be even cooler than Friday. The best chance for showers will be in higher elevations and Northern zones of our region, but light showers will also be possible in the valley earlier in the day. Temperatures will start out in the 50's in the valley and will top out in the mid 70's, foothill areas wil start out in the 40's to 50's, and will end up in the mid to high 60's, and mountain areas will start out in the 30's to 40's, and end up in the low to mid 60's on Saturday afternoon. Winds will be out of the South to around 15mph, and we'll continue to have the potential for gusts up to around 25mph. The potential for showers is mostly expected to wrap up by late Saturday night.
Low pressure exits to our East as we head into your Sunday and high pressure will be building in from the Pacific. This will result in clearing skies, warming temperatures, and dry conditions over Northern California. Valley areas will end up back in the mid to high 80's on Sunday, while foothill and mountain areas climb back into the mid to high 70's. Valley areas will end climb back into the 80's to low 90's on Monday afternoon, whlie foothill and mountain areas end up in the 70's to low 80's. Low pressure tracking through to our North will keep our high temperatures somewhat in check for the start of next week, and will also bring a slight chance for showers to areas close to the Oregon border on Monday and Tuesday. High pressure will continue to be the dominant feature in your extended forecast, and will result in dry and very hot conditions on the way for the latter half of next week. Valley areas are projected to end up back in the mid 90's to low triple digits, while foothill and mountian areas climb back into the mid 80's to 90's late next week.
