...NO SVR TSTM AREAS FORECAST...
...SYNOPSIS...
UNLESS DANNY SKIRTS THE SRN NEW ENGLAND COAST...IT APPEARS MUCH OF
THE CONVECTION ACROSS THE ERN/SRN CONUS WILL STRUGGLE TO OBTAIN ANY
SIGNIFICANT INTENSITY/LONGEVITY AS SHEAR/INSTABILITY ARE EXPECTED TO
REMAIN SOMEWHAT MARGINAL. THE ONLY EXCEPTION TO THIS MIGHT BE ALONG
THE OH RIVER VALLEY IMMEDIATELY AHEAD OF COLD FRONT. MODELS SUGGEST
A NARROW WEDGE OF MOISTURE/INSTABILITY WILL ADVECT NEWD ACROSS KY
INTO SRN OH/WV PRIOR TO WIND SHIFT. ANY STORMS THAT DEVELOP ALONG
THIS BOUNDARY WILL DO SO ALONG SRN FRINGE OF STRONGER FLOW WHICH
COULD LEAD TO A FEW ROBUST STORMS. OTHERWISE...ACTIVITY ACROSS THE
CONUS SHOULD REMAIN SOMEWHAT MARGINAL.
