We had wet, active, cool, and windy weather across Northern California on Tuesday. Showers have persisted across mountain areas through the day, but we did have a bit of a lull in the valley this morning. Showers and thunderstorms then developed through the day. Thunderstorms brought heavy rain, and hail to portions of Shasta and Tehama Counties this afternoon. Mid valley areas had heavy showers mainly in the afternoon. We'll be seeing showers and the thunderstorm activity winding down tonight in the valley. Rain and snow showers are expected to continue in the mountains this evening. Snow level could be dipping to as low as 5000' tonight. Winds have been up to around 20mph out of the South in the valley and we've had gusts up to around 30mph for most of the valley. The strongest winds today were observed in Red Bluff, where sustained winds reached 26mph, and gusts topped 40mph this afternoon.
The trend of wet and cool weather will continue on Wednesday. We'll see a slight chance for showers early in the day on Wednesday and then a much better chance for showers in the afternoon. Snow levels will rise from around 5500' in the morning to around 7000' in the evening. Temperatures will start out in the 40's to 50's in the valley, in the mid to high 40's in the foothills, and in the 30's to 40's in the mountains. High temperatures are projected to top out in the mid to high 60's in the valley, in the 50's to low 60's in the foothills, and in the 50's for most mountain areas. Winds will be out of the South to around 15mph, but we are not expecting gusty conditions like we saw on Tuesday.
There will be a lingering chance for showers on Thursday, but temperatures will become slightly warmer for your afternoon. Most of the valley will end up in the 60's to low 70's, while we'll still be in the 50's to low 60's in the foothills and mountains. The best chance for showers will be to the North, with the shower threat diminishing heading to the South. High pressure will bring us a brief break from the wet weather and a return to average temperatures on Friday. We'll be partly cloudy to mostly sunny in the valley and have high temperatures in the high 70's to low 80's. Mountain and foothill areas will end up back in the 70's for the end of the week and the start of your weekend.
Another area of low pressure will be bringing wet and cooler weather back to your forecast late Saturday through at least Monday of your extended forecast. Showers will be likely from Saturday night through Monday, with the chance for showers lingering into your Tuesday. Temepratures in the valley will end up back in the 60's on Sunday and Monday. This next wet system currently looks to provide more moisture than the current system we're tracking for your on Tuesday evening. That is subject to change in the next few model runs, but is very positive news given how dry we've been over the last several months.
