Storms have developed...
Josh Larson @ 1:05 PM
Scattered showers and thunderstorms are likely across the DC metro area from 2pm through the evening hours as enough daytime heating and an approaching cold front have provided ample atmospheric dynamics.
The Storm Prediction Center in Norman, Oklahoma does not anticipate issuing a Severe Thunderstorm Watch, but does have this to say:
MESOSCALE DISCUSSION 1763
NWS STORM PREDICTION CENTER NORMAN OK
AREAS AFFECTED...E VA...E NC...MD...DE...DC
CONCERNING...SEVERE THUNDERSTORM POTENTIAL
ISOLATED SEVERE STORMS ARE POSSIBLE OVER E VA, E NC, MD, DE, AND DC OVER THE NEXT FEW HOURS. A WW IS NOT EXPECTED. VORTICITY MAXIMUM NOTED ON SATELLITE IMAGERY IS AIDING ONGOING CONVECTION OVER WEST VA ATTM. AS THIS FEATURE MOVES EASTWARD INTO VA AND INTO A MODERATELY UNSTABLE AIRMASS, VERTICAL MOTION WILL INCREASE AND HELP AID IN THE DEVELOPMENT OF A FEW ISOLATED SEVERE STORMS. MARGINAL VERTICAL WIND PROFILES NOTED ON FORECAST SOUNDINGS, AS WELL AS POOR LAPSE RATES, SUGGEST THAT THE NATURE OF ANY STORMS WILL LIKELY BE DISORGANIZED. THE MAIN THREAT FROM THE STRONGEST STORMS WILL BE ISOLATED WIND DAMAGE.
