Mesoscale Discussion 0495
NWS Storm Prediction Center Norman OK
0440 PM CDT Thu Apr 14 2022
Areas affected...Parts of northeast NC...southeast VA...southeast
MD...and DE
Concerning...Severe potential...Watch unlikely
Valid 142140Z - 150015Z
Probability of Watch Issuance...20 percent
SUMMARY...Isolated strong to locally damaging wind gusts will be
possible across parts of the Mid-Atlantic states during the next few
hours.
DISCUSSION...Latest mosaic radar imagery shows a few loosely
organized multi-cell clusters spreading east-northeastward along and
immediately ahead of an eastward-advancing cold front. Surface
observations ahead of the approaching convection show temperatures
in the lower 80s and dewpoints in the lower 60s, with steep
low-level lapse rates. This is contributing to 500-1000 J/kg of
MLCAPE, while VWPs and RAP mesoanalysis show effective bulk shear of
30-40 knots. While surface flow is generally veered ahead of the
approaching cold front and convection, the co*bination of a
moist/well-mixed boundary layer and sufficient deep-layer shear
could support a few strong to locally damaging wind gusts with any
organized multi-cell clusters during the next few hours prior to
nocturnal boundary-layer stabilization.
