Valley T-Storms Tuesday

Apr 6, 2015 8:51 PM by Kris Kuyper

Skies turned mostly cloudy by Monday afternoon around the North State, but we were mostly dry. Valley rain/T-Storms and mountain snow are all heading our way for Tuesday, as it should be a much more active day!

Cold low pressure off the Oregon coastline is pushing a nice band of rain & snow our way. Ahead of it, gusty south winds have developed and will continue overnight. Wet weather should arrive early tomorow morning, and last through about mid-day in the Valley. By the afternoon, cold and very unstable low pressure will rotate right over us, and that is a good set-up for strong Valley thunderstorms to form. Because the low is cold, hail should accompany most stronger thunderstorms. The best wind shear from this system will be in the morning, but there will still be just enough that a funnel cloud is possible in some of the stronger afternoon storms.

In the mountains, it will be snow above 3500'. Lake Almanor is around 4500', and at that elevation, 1/2 to 1 foot of new snow is possible by Wednesday morning! If you're going to be driving in the mountains on Tuesday, definitely carry chains or take your 4WD vehicle as you can expect winter driving conditions.

The storm should be east of us by Wednesday. Skies will slowly clear through the day, and temperatures will return to near normal by Thursday afternoon. A weak storm will brush us on Saturday, but any kind of wet weather will be very light (if anything at all). Temperatures will cool only a little.

But a potent Spring storm will arrive Tuesday, with Valley rain and thunderstorms, and much needed mountain snow!
