 MESOSCALE DISCUSSION 0452 NWS STORM PREDICTION CENTER NORMAN OK 0730 PM CDT SAT MAY 01 2010 AREAS AFFECTED...NERN AR/MO BOOTHEEL/WRN TN/NWRN MS CONCERNING...SEVERE POTENTIAL...TORNADO WATCH LIKELY VALID 020030Z - 020100Z NEW PDS TORNADO WATCH WILL BE NEEDED FOR NERN AR...MO BOOTHEEL... WRN TN AND NWRN MS. VISIBLE SATELLITE IMAGERY AND SURFACE OBSERVATIONS INDICATED CLEARING SKIES LATE THIS AFTERNOON/EARLY EVENING FROM EAST CENTRAL AR INTO FAR NWRN MS/SWRN TN HAVE ALLOWED TEMPERATURES TO RECOVER INTO THE UPPER 70S WITH CONTINUED MOISTURE RETURN /SURFACE DEWPOINTS LOWER-MID 70S/. RECENT TRENDS IN THE MEM WSR-88D VWP INDICATED AN INCREASE IN LOW LEVEL SHEAR/HODOGRAPH CURVATURE...WITH SFC-1 KM SRH INCREASING FROM 100 M2/S2 AT 22Z TO 300 M2/S2 AT 00Z. THIS COMBINED WITH THE GREATER INSTABILITY ACROSS THIS REGION AND THE APPROACH OF STRONG TO SEVERE STORMS FROM CENTRAL AR SUGGESTS A NEW TORNADO WATCH WILL BE NEEDED TO THE E/NE OF WW 125. GIVEN THE STRENGTH OF THE LOW LEVEL SHEAR WITH A FURTHER INCREASE EXPECTED AS THE LLJ STRENGTHENS ACROSS THIS AREA TONIGHT...THIS WATCH WILL ALSO NEED TO BE A PDS TORNADO WATCH. ..PETERS.. 05/02/2010 |
