MESOSCALE DISCUSSION 0221 NWS STORM PREDICTION CENTER NORMAN OK 1015 PM CDT FRI MAR 28 2014 AREAS AFFECTED...LA...MS CONCERNING...TORNADO WATCH 41... VALID 290315Z - 290515Z THE SEVERE WEATHER THREAT FOR TORNADO WATCH 41 CONTINUES. SUMMARY...A MAINLY DAMAGING WIND THREAT PERSISTS ACROSS THE TORNADO WATCH...WITH A LESS THREAT OF TORNADOES AND LARGE HAIL. DISCUSSION...TWO DISTINCT LINES OF STORMS CURRENTLY EXIST BUT WILL CONTINUE TO MERGE WITH TIME AS THEY CROSS THE MS RIVER. GIVEN THE LINEAR STORM MODE...THE MOST LIKELY SEVERE THREAT IS DAMAGING WINDS. HOWEVER...SOME OF THE CORES ACROSS NWRN MS LIKELY CONTAIN HAIL. TORNADO POTENTIAL APPEARS TO BE DECREASING ACROSS THE WATCH AS THE LINE CONTINUES TO OVERTURN THE MOST UNSTABLE AIR. FARTHER E INTO CNTRL AND ERN MS...THE AIR MASS IS LESS UNSTABLE...WITH BOUNDARY LAYER DEWPOINTS ONLY IN THE UPPER 50S F. THE BEST WINDOW FOR AN ISOLATED TORNADO WOULD THUS APPEAR TO BE ACROSS SRN LA WHERE DEWPOINTS ARE NEAR 70 F.
