View looking south from Kitt Peak this afternoon shows some blowing dust in the boundary layer, but nothing like yesterday's dust event across the Great Basin and into Salt Lake City.Strong, short-wave trof at 500 mb will cross the state tomorrow with an intense vorticity maximum. A leading S/W will pull rapidly northward across the state during the early morning hours carrying several embedded vorticity maxima with it. So, April begins with another strong and complex storm crossing Arizona and good chances for convective storms and precipitation across most of the state.
