One last day of mostly sunny skies and highs near 70 for the valley floor. Cold front begins to push into the Northstate by the late morning hours Wednesday.
Clouds will start to roll in this evening and into the overnight hours. Overnight clouds and higher dewpoints will likely keep the majority of the Northstate much warmer tomorrow morning compared to the last few days.
Most hi-res models begin to push the brunt of the moisture into the Northstate by the mid to late afternoon hours on Wednesday. Looking over forecast soundings and profiles, snow levels will struggle to drop below 5500 ft most of the day Wednesday.
As the cold pool aloft moves over Thursday we may briefly see snow levels drop below 4500 ft. Another thing to watch out for is convective weather/thunderstorms Thursday around noon. Some models bring in about 500 j/kg of CAPE, enough to fire a few thunderstorms. The main limiting factor as usual will be how much clearing we can get to initialize thunderstorms.
Another wave of rain will move in by Friday morning and afternoon. However, this second wave will be centered further south, Central and Southern California will feel the full brunt of this storm, though the Northstate will still see widespread precipitation.
Remaining showers will stay in place Saturday but not nearly as wet as Wednesday's & Friday's system.
The Northstate will begin to clear-out by Sunday.
