DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK

VALID 200100Z - 201200Z
...NO SVR TSTM AREAS FORECAST...
...PARTS OF THE NORTHEAST...
MARGINAL WIND/TORNADO THREAT MAY PERSIST NEXT FEW HOURS WITH NARROW
QLCS FROM SERN PA TO THE WRN SHORE OF CHESAPEAKE...AIDED BY THE
PRESENCE OF A WEAK SURFACE CYCLONE NEAR BWI ALONG A N/S-ORIENTED
FRONTAL BOUNDARY. PRESENCE OF STRONG DEEP SHEAR OWING TO 60-70 KT
500 MB S/SWLYS SAMPLED IN AREA RAOBS WILL SUPPORT EMBEDDED
CIRCULATIONS CAPABLE OF LOCALIZED DAMAGING WINDS AND A BRIEF/WEAK
TORNADO. BUT ORIENTATION OF THE SHEAR VECTOR NEARLY PARALLELING THE
LINE...ALONG WITH BOUNDARY LAYER COOLING OCCURRING WITHIN THE WARM
SECTOR SUGGESTS THE OVERALL THREAT HAS PROBABLY PEAKED. THE SEVERE
RISK SHOULD DIMINISH AS LOW-LEVEL FLOW WEAKENS AND LARGE-SCALE
ASCENT WANES OVERNIGHT.
