DAY 3 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0212 AM CDT THU OCT 26 2006
VALID 281200Z - 291200Z
...NO SVR TSTM AREAS FORECAST...
...SERN U.S...
STRONG FRONTAL BOUNDARY WILL PROGRESS INTO THE COASTAL
CAROLINAS...EXTENDING SWWD OVER THE CNTRL FL PENINSULA BY 28/12Z.
THIS BOUNDARY WILL BE STRONGLY FORCED...ESPECIALLY ACROSS THE MIDDLE
ATLANTIC...WHICH SHOULD ENHANCE THE THREAT FOR A NARROW LINE OF
THUNDERSTORMS ALONG THE WIND SHIFT. MAIN IMPEDIMENT FOR POTENTIAL
SEVERE THIS PERIOD WILL BE THE POOR LAPSE RATE ENVIRONMENT AND WEAK
INSTABILITY. REGARDLESS OF THE MEAGER INSTABILITY...IT APPEARS
STRONG SHEAR AND FORCING WILL ENHANCE THE THREAT OF AT LEAST A FEW
STRONG STORMS...ESPECIALLY IF SUPERCELL STRUCTURES CAN DEVELOP.
STORMS WILL QUICKLY MOVE OFF THE MIDDLE ATLANTIC COAST BY
18Z...WHILE STORMS MAY LINGER ACROSS THE CNTRL/SRN FL PENINSULA WELL
INTO THE AFTERNOON HOURS. UNCERTAINTY IN MOISTURE/INSTABILITY AHEAD
OF THIS FRONTAL SYSTEM WILL PREVENT MORE THAN LOW PROBABILITIES FOR
SEVERE THUNDERSTORMS THIS PERIOD.
