Keep that jacket and umbrella handy. More wet weather is on the way for your work week, but we are expecting a lull in the shower activity during the day today. Showers are wrapping up from the first wet system early this morning ahead of the second wet system that's projected to arrive tonight. Scattered showers will be possible through the day, but are not expected to be as heavy as Tuesday's. There is a slight chance for thunderstorms this afternoon, and a slightly better potential for instability Thursday morning. Temperatures have dipped into the high 40's to mid 50's in the valley overnight, and into the 30's to low 40's in the mountains this morning. Winds are expected to be up to 10mph out of the South today, and humidity will stay above 70 percent. High temperatures are projected to climb into the mid to high 50's in the valley this afternoon, and into the mid to high 40's in the mountains later today.

Heavy rain and snow will be returning to the region tonight. Several watches and warnings will be in effect with the active weather ahead. A Winter Storm Warning will be in place for the Sierra above 4000' from this evening through Friday morning, and a Flash Flood Watch will be in place around recent burn scars due to the threat of debris flows if rain becomes heavy enough. The Winter Storm Warning will be in effect due to the potential for heavy snow down to lower elevations tonight through Friday morning. The Flash Flood Watch will be in place from this evening through Thursday morning. Snow levels will be down to around 3500', which will be the lowest we've seen this year. Mountain travel will be impacted. Looks like most of the active weather should subside by Thursday night, with only scattered showers lingering in the wake of the second system this week. Another wet system is expected to bring more valley rain and mountain snow to the region from Friday afternoon through Saturday afternoon. Snow levels could be below 5000' with that system. Showers will wrap up in the valley on Saturday night, but could linger into early Sunday. There will be more potential for active weather next week, but models are currently split on when the next wet system will arrive.

Rain showers and a good chance for thunderstorms are on the way for your Friday night and Saturday forecast. We'll also be much cooler and have gusty South winds this weekend. Some showers are possible early next week, but dry and warmer weather returns for the middle of next week.
