Get ready for a very wet, active, and cooler day across Northern California. Showers have persisted in the mountains overnight, and valley showers are projected to return early today. Mid valley areas will have showers in time for your morning commute, and the North end of the valley will have showers soon after. The wet weather is tracking South to North today as a wet system is set up along the Coast, just South of the Bay Area. This will continue to funnel more moisture and showers through our region today. Thunderstorms will be likely across almost all areas this afternoon, and will have the potential to produce hail. Snow levels could dip to around 6500', so higher peaks will see some snow over the next 24 hours. Temperatures are starting out in the mid 50's to low 60's in the valley this morning, and in the 40's to low 50's in the mountains. High temperatures are projected to climb into the mid 60's in the valley today, and into the mid 50's to low 60's in the mountains. Winds will be out of the South up to 20mph, with gusts up to 30mph possible in the afternoon. Showers and thunderstorms will last into tonight, but are expected to mostly taper off by Saturday morning.
Some showers will be lingering into the start of your Saturday, but most of those will be limited to the Sierra. Dry weather is expected by late morning in the valley, and mountain areas will mostly dry out by the afternoon. There will be a substantial warming trend ahead for your Memorial Day Weekend. Valley areas will climb back into the high 70's on Saturday, then into the high 80's on Sunday, and then into the mid 90's on Monday! We will still have some clouds over the region on Saturday, but skies will be sunny for Sunday and Monday. Make sure you're prepared for the rapid rise in temperatures. Dress in light clothing, stay hydrated, and avoid physical activities outdoors during the peak heat of the day. Temperatures will stay in the mid 90's for the valley on Tuesday.
Temperatures are expected to dip towards the middle of next week, and we could get more showers in the mountains. We'll get a much better idea of what to expect in your extended forecast when models come to a better agreement over the next few days.
