High pressure centered off the West Coast in the Pacific conitnues to be the dominant feature in our forecast but a pair of low pressure areas are bringing some impacts in your late week forecast. Temperatures will continue to be very warm, and we'll mostly be dry through the end of the week due to the high pressure. Low pressure dropping down the coast of California today has brought thin clouds and modest South winds to your Wednesday afternoon. That low pressure area will continue to track towards and then through Southern California late this week. The area of low pressure to our East will bring the potential for gusty North winds back to Northern California on Thursday afternoon into Friday. Winds could top out in the 20 to 30mph range out of the North late this week in the valley. There will also be a slight chance for showers and thunderstorms in the foothills and Sierra late week, but the biggest threat will stay to our South.
Temperatures were very warm for your Wednesday afternoon. Valley areas topped out in the 70's to 80's, while foothill and mountain areas ended up in the 60's to 70's. Winds were out of the South to around 10mph. Valley areas will continue to have low temperatures in the 40's to 50's and high temperatures in the 70's to 80's through Friday. Mountain areas can expect low temperatures in the 30's to 40's and high temperatures in the 60's to 70's through the end of your work week. Winds will be out of the North and gusty on Thursday and Friday.
A weak area of low pressure will brush over our region From the North as we head through your weekend and will result in cooler temperatures and increasing clouds. There will also be a chance for light showers, with the best chance for showers resting in higher elevations on Saturday into early Sunday. A second area of low pressure will move through Northern California from Sunday through the start of next week and that will bring a better chance for more widespread showers to our region. Showers will be very light and snow levels will be above 6500'. Up to around a tenth of an inch of rain looks possible in the valley, while higher elevations may see up to around a half an inch. High temperatures will dip into the low to mid 70's in the valley on Saturday and into the 60's to 70's on Sunday and Monday. Mountain areas can expect high temperatures in the 50's to 60's by the end of this weekend and the start of next week. Low temperatures are not expected to change much through your extended forecast.
We'll continue to have a slight chance for showers on Tuesday, but temperatures will be warming back into the mid 70's in the valley. We'll have some clouds moving through our region but should be warm and mostly dry for the middle of next week.
