One more hurrah for Winter?

TUCSON – In what’s already been a very wet, white and – even at times – cold WInter, southern Arizona is bracing for what could be the season’s final storm. Winter officially ends Wednesday, March 20th.

A strong, and cold area of low pressure is currently spinning south of the area – in Baja California, and a cold front will slide to the north overnight. This will bring widespread valley rain and mountain snow.

Winter Storm Warnings have been issued for the mountaintops above 6500′, where 8-18″ of snow is possible. The large spread in the forecast is due to the potential of some embedded thunderstorms. If thunder occurs, precipitation rates will go up.

Here’s a look at what we can expect in terms of timing and amounts of rain and snow.

Prime time for heavy rain and mountain snow look to be overnight Monday and into the first half of Tuesday. If we see some breaks of sun later on Tuesday, some of those thunderstorms could be seen.

The storm should be gone midday Wednesday and much drier air will work back into the region. Below average temperatures will continue through the weekend.
