Chance for thunderstorms today, cold rain next week.

An upper level low will drop into northern California today.  It pushed a decent amount of rain in last night but the showers are starting to fade and we could get some clearing on the back side of the front mid afternoon.  The problem with the sunshine is the cold pool of air aloft will quickly destabilize the atmosphere and could make for an explosive convective situation today.  In addition there is some decent sheering (winds turning with height) which opens up the possibility for some rotation in some of these storms.  The NWS doesn’t believe – and the numbers agree – that the sheering will likely not be a strong as the situation on Wednesday, but any rotating thunderstorm is cause for alarm and needs to be watched very closely.  The hotbed areas will likely be in the same place as on Wednesday, so the Corning, Orland, Willows areas of Tehama, Glenn and western Butte Counties.  We’ll be on top of any storms that do form and we’ll have a complete update for you as it occurs.

The rest of the week the weather stays unsettled.  Another few storms will roll in off the Pacific bringing more rain and showers to the NorthState.  A few will be pretty cold and could bring snow levels down as far as 3,000 feet.  That’s great, but we need a whole lot more than just one or two storms to make up for our deficit – snowpack levels are running near 25% of normal.  The trough pattern remains all week, and we’ll have some good drought-reducing weather through the end of the week before things start to dry out a little bit during the middle of the week.
