Severe Weather along most of the EC Possible This Afternoon

[Colin]

A slow moving cold front is very slowly moving to the East...parts of the Northeast and Middle Atlantic have been getting slammed the past 2 days with heavy rain and severe thunderstorms...the Lehigh Valley International Airport has reported almost 3.5" of rain since Monday...and with another 1-4" possible today.

The whole Eastern Seaboard is under a slight risk for severe thunderstorms this afternoon... http://www.spc.noaa.gov/products/outlook/day1otlk.html

The areas at most risk this afternoon seem to be: Extreme Southeast New Jersey, Southern Delaware, Southern Maryland, Southeastern Virginia, Eastern North Carolina, Most of South Carolina, and East Central Georgia. Everyone in those areas, as well as the entire Eastern Seaboard should monitor the skies and the latest updates from your local NWS and the SPC.

NWS STORM PREDICTION CENTER NORMAN OK
1205 PM CDT WED JUL 23 2003

AREAS AFFECTED...VA/ERN WV/MD/ERN PA/NRN NJ/SERN NY

CONCERNING...SEVERE THUNDERSTORM POTENTIAL

VALID 231705Z - 231900Z

CONVECTION WILL LIKELY CONTINUE TO DEVELOP ALONG THE E EDGE OF THE
APPALACHIAN MTNS. THE LARGE HAIL AND/OR DAMAGING WIND POTENTIAL WILL
GRADUALLY INCREASE AND A WW MAY BECOME NECESSARY OVER THE NEXT FEW
HOURS.

VIS SAT IMAGERY SHOWS A CLEARING ACROSS CNTRL AND NRN VA EXTENDING N
INTO SRN PA. AS A RESULT...SFC TEMPS HAVE WARMED INTO THE UPPER 70S
IN THIS AREA. THIS COMBINED WITH SFC DEWPOINTS IN THE MID 60S TO
LOWER 70S F HAS RESULTED IN MARGINAL INSTABILITY AND STORMS ARE
BEGINNING TO INITIATE. A STRONG MID-LEVEL JET WITH 60 KT AT 500 MB
IS CURRENTLY ROUNDING THE BASE OF THE UPPER-TROUGH OVER THE OH
VALLEY AND CNTRL APPALACHIAN MTNS. THIS WILL RESULT IN ABOUT 50 KT
OF DEEP LAYER SHEAR IN THIS REGION AND WILL LIKELY BE FAVORABLE FOR
ORGANIZED SEVERE STORMS. AS INSTABILITY CONTINUES TO INCREASE
THROUGH THE AFTERNOON...UNIDIRECTIONAL SHEAR PROFILES WILL RESULT A
POTENTIAL FOR WIND DAMAGE. ALSO LARGE HAIL WILL BE POSSIBLE
ESPECIALLY OVER THE APPALACHIAN FOOTHILLS WHERE MID-LEVEL TEMPS WILL
BE SLIGHTLY COOLER.
