Grab your sunglasses, dress for the heat, and have some extra water handy as you're getting ready to head out the door today. High pressure is still the biggest influence on our regoin today, but low pressure is starting to move into our region. Thin clous have started to track through northern California this morning, and we'll continue to see more streaming through throughout your Monday. Partly cloudy to mostly sunny skies are expected across our region today, but we'll be staying dry. We'll also have very warm temperatures continuing in your Monday forecast. Temperatures have dipped into the 40's to 50's in the valley and foothills overnight, and into the 20's to 40's in our mountain zones early today. Winds are mostly ligt and out of the northeast this morning, but some areas will have a shift in the winds this afternoon. The north valley will have winds out of the north to 15mph today, while mid valley areas will have a shift to winds out of the south to 10mph. Foothill and Sierra locations can expect west winds to 10mph this afternoon. High temperatures will continue to be well above average this afternoon, but most areas will fall short of what we had on Sunday. Valley areas will top out in the mid 80's to low 90's, foothilla reas will end up in the 70's to lower 80's, and out mountain zones are mostly projected to top out in the 70's on Monday afternoon.
Low pressure will take hold of northern California on Tuesday, and that will result in a substantial drop in temperatures, the potential for showers, and periods of gusty north winds in the afternoon. The best chance for showers will be in our mountain zones, but we can't rule out some very limited showers in the valley. There will also be the potential for mountain thunderstorm activity on Tuesday. High temperatures are projected to end up in the lower 80's in the valley, 60's to lower 70's in the foothills, and 60's in the mountains on Tuesday. Dry weather and a modest rise in temperatures can be expected on Wednesday as the low pressure tracks to our east. We'll end up with sunny to mostly sunny skies on Wednesday and Thursday.Temperatures will climb back into the mid 80's in the valley, and 60's to mid 70's in the foothills and mountains on Wednesday and Thursday.
Low pressure approaching the West Coast from the Gulf of Alaska will pack a bigger punch in your extended forecast. This will result in temperatures cooling by several degrees on Friday, and clouds increasing across our region. An even bigger drop in temperatures can be expected this weekend, and the potential for widespread showers will return to northern California. Lighter showers are expected on Saturday, with the brunt of the wet weather expected to stay in our higher elevations and northern zones. Much more widespread rain and mountain snow is then currently projected to move through our region on Sunday. Temperatures will dip into the 60's to mid 70's in the valley on Saturday, and then into the 50's to mid 60's in the valley on Sunday. Foothill and mountain areas are currently projected to end up in the 60's on Saturday, and then fall into the 50's on Sunday. This is great news as we desperately need the rain across our region. A lot can change in our models and the weather pattern over the next several days, but the current outlook for wet weather this weekend looks very promising.
