Mesoscale Discussion 1501
NWS Storm Prediction Center Norman OK
1229 PM CDT Wed Jul 17 2019
Areas affected...portions of the Mid-Atlantic
Concerning...Severe potential...Watch unlikely
Valid 171729Z - 172000Z
Probability of Watch Issuance...20 percent
SUMMARY...Storms will move east-northeast off the Appalachians this
afternoon across the Mid-Atlantic. Damaging winds may occur and a
severe thunderstorm watch issuance is unlikely.
DISCUSSION...Ahead of an approaching upper-level shortwave trough,
storms started developing over the Appalachians late this morning
and coverage is expected to increase this afternoon/evening as they
move east-northeast. A hot, moist airmass is in place with surface
temperatures in the 90s F and dewpoints into the 70s. As a result,
MLCAPE has increased to 1000-2000 J/kg and will likely eclipse 3000
J/kg in the Tidewater/Chesapeake Bay regions this afternoon. With
rather weak shear, multicellular development is expected with
outflow dominant storms likely. Some upscale growth is possible
given the presence of the upper-level trough, 25 knot mid-level
flow, and strong buoyancy in the area. This would locally enhance
the threat for damaging winds, and steepening low-level lapse rates
and anticipated outflow dominant storms will also likely result in
strong wind gusts.
