yoda Posted June 28, 2013 Share Posted June 28, 2013 DISCUSSION...BAND OF STG-SVR TSTMS ACROSS SWRN PA...GARRETT COUNTY MD AND NERN WV IS MOVING THROUGH RELATIVE MOISTURE MIN ATTM...BUT WILL ENCOUNTER SUBSTANTIALLY RICHER THETAE OVER ERN MTNS AND ADJOINING PIEDMONT. SEVERAL REPORTS OF TOPPLED TREES HAVE BEEN RECEIVED FROM PASSAGE OF THESE TSTMS. FURTHER INTENSIFICATION OF THIS ACTIVITY IS POSSIBLE...AS IS CONTINUED SVR THREAT WITH MORE WIDELY SCATTERED BLEND OF DISCRETE AND CLUSTERED CONVECTIVE MODES FARTHER E TOWARD DE VALLEY AND CHESAPEAKE BAY REGIONS. UPSCALE AGGREGATION OF COLD POOLS IS POSSIBLE FROM ANY OF THIS ACTIVITY...ENHANCING POTENTIAL FOR FORWARD-PROPAGATIONAL DAMAGING WIND ON MESOBETA SCALE. SOME SUPERCELL RISK ALSO EXISTS...PRIMARILY FROM EXTREME SRN PA SWD ACROSS ERN WV PANHANDLE AND MD INTO NRN VA...THEN SHIFTING EWD OVER DELMARVA/NJ. THAT AREA LIES BENEATH ENHANCED BELT OF MID-UPPER LEVEL FLOW THAT OFFSETS VEERED BOUNDARY LAYER WINDS ENOUGH TO GENERATE 40-50 KT EFFECTIVE SHEAR MAGNITUDES. PRECONVECTIVE AIR MASS SHOULD REMAIN FAVORABLY UNSTABLE FOR NEXT FEW HOURS...WITH SFC DEW POINTS 70S F IN LOWER ELEVATIONS AND INSOLATION CONTRIBUTING TO MLCAPE 1500-2500 J/KG E OF BLUE RIDGE. http://www.spc.noaa.gov/products/md/md1292.html Link to comment Share on other sites More sharing options...

Kmlwx Posted June 28, 2013 Share Posted June 28, 2013 I'm hesitant to say the line will be all that impressive here. I guess we have a chance north of DC but there's been rain there as well. Question is how bad the overturning is - probably much worse to the south but damage might be done across the entire metro. Link to comment Share on other sites More sharing options...
