MESOSCALE DISCUSSION 0113
NWS STORM PREDICTION CENTER NORMAN OK
0122 PM CST SUN FEB 22 2026
AREAS AFFECTED...PARTS OF EASTERN MARYLAND AND DELAWARE INTO FAR
SOUTHERN NEW JERSEY
CONCERNING...HEAVY SNOW
VALID 221922Z - 222145Z
SUMMARY...HEAVY SNOW IS BEGINNING OVER PARTS OF THE COASTAL MID
ATLANTIC, AND IS EXPECTED TO BECOME MORE PREVALENT LATER THIS
AFTERNOON INTO EARLY EVENING. 1+ INCH/HOUR SNOWFALL RATES ARE
POSSIBLE.
DISCUSSION...MESOANALYSIS TRENDS INDICATE SURFACE LOW
INTENSIFICATION JUST OFFSHORE, WITH 850-700 MB WARM-AIR/MOISTURE
ADVECTION AND FRONTOGENESIS INCREASING ALONG THE MD/DE COASTLINE
AREAS. TEMPERATURES THROUGH THE COLUMN ARE LARGELY BELOW FREEZING,
AS SUGGESTED BY THE IAD 18X OBSERVED SOUNDING. WHILE SURFACE
TEMPERATURES ARE STILL ABOVE FREEZING OVER MOST LOCALES, SURFACE
OBSERVATIONAL TRENDS SHOW TEMPERATURES PLUMMETING ALONG THE ATLANTIC
COASTLINE. BOTH SURFACE OBSERVATIONS AND TRAFFIC CAMERA NETWORKS
DEPICT HEAVY FALL RATES OF LARGE DENDRITES, WITH KDOX
DUAL-POLARIMETRIC RADAR ALSO SUGGESTING A TRANSITION TO MAINLY HEAVY
SNOW. STRONG 700 FRONTOGENESIS SHOULD CONTINUE TO PROMOTE STRONG
CONVERGENCE AND LIFT WITHIN THE DENDRITIC GROWTH ZONE, SUPPORTING
CONTINUED HEAVY SNOW POTENTIAL, INCLUDING 1+ INCH/HOUR RATES.
IN THE NEAR TERM, HEAVY SNOW SHOULD BE MOST COMMON IN EASTERN MD,
DE, AND PARTS OF EXTREME SOUTHERN NJ. HOWEVER, THESE CONDITIONS
SHOULD BECOME MORE COMMONPLACE LATER THIS AFTERNOON AND EVENING,
PERHAPS WITH BLIZZARD CONDITIONS, AS THE SURFACE LOW CONTINUES TO
DEEPEN FURTHER.
