MESOSCALE DISCUSSION 1722
NWS STORM PREDICTION CENTER NORMAN OK
0321 PM CDT SAT JUL 19 2025
AREAS AFFECTED...EASTERN VIRGINIA AND FAR NORTHEAST NORTH CAROLINA
CONCERNING...SEVERE THUNDERSTORM WATCH 526...
VALID 192021Z - 192215Z
THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 526
CONTINUES.
SUMMARY...THE THREAT FOR DAMAGING/SEVERE WINDS WILL BECOME
INCREASINGLY CONCENTRATED ACROSS EASTERN VIRGINIA OVER THE NEXT
SEVERAL HOURS.
DISCUSSION...A MIXTURE OF SEMI-DISCRETE CELLS AND CONVECTIVE
CLUSTERS CONTINUE TO EVOLVE ACROSS CENTRAL VA AND NORTHERN NC, AND
HAVE A HISTORY OF SPORADIC WIND DAMAGE AND SMALL HAIL. RECENT GOES
IR IMAGERY AND MRMS VERTICALLY INTEGRATED LIQUID/ECHO TOP DATA
CONTINUE TO SHOW TRANSIENT, BUT INTENSE, CONVECTIVE CORES DEVELOPING
ACROSS THE REGION AS STORMS MOVE INTO, OR DEVELOP WITHIN, A VERY
BUOYANT ENVIRONMENT. RECENT RAP MESOANALYSIS ESTIMATES SUGGEST
MLCAPE HAS INCREASED TO 2000-3000 J/KG ACROSS EASTERN VA AS
TEMPERATURES CLIMB INTO THE UPPER 80S AND LOW 90S WITH LOW-LEVEL
LAPSE RATES BETWEEN 7-7.5 C/KM. THE TRAJECTORIES OF ONGOING CELLS
AND CLUSTERS SUGGESTS THAT STORM INTERACTIONS/CONVERGENCE WILL
BECOME INCREASINGLY LIKELY ACROSS EASTERN VA WITHIN THIS CAPE
MAXIMUM OVER THE NEXT SEVERAL HOURS. AS THIS OCCURS, THE FAVORABLE
THERMODYNAMIC ENVIRONMENT SHOULD SUPPORT AN UPTICK IN STORM COVERAGE
ALONG WITH INCREASING PROBABILITY FOR DAMAGING DOWNBURST WINDS AND
PERHAPS SMALL HAIL.
