This radar grab from 3:13 p.m. illustrates the showers that sped through northern Virginia today, including the warned storm shown above that had 1.0 inch hail reported near Dale City.  There were also a couple of unofficial local hail reports around the Fredericksburg area from other cells.  Following a cold frontal passage around noon a cold air pool aloft enhanced the instability that created these showers.
As far as Tuesday’s severe potential goes the current models are indicating a cold frontal passage in the morning, robbing storms of the additional instability that would result from peak heating in the afternoon.  Regardless, I’ll be watching radar for anything worth scooting outside to witness while hoping that the models are incorrect and/or the front slows down.  An April chase would be great!
