   BRIEF TORNADO OR TWO MAY OCCUR WITH THE STRONGER CELLS. HAIL AND
   STRONG GUSTY WINDS MAY ALSO ACCOMPANY THE ACTIVITY. THE THREAT
   SHOULD BE TOO BRIEF TO WARRANT A WW EARLY THIS EVENING ACROSS THE
   REGION.
   
   LATEST SFC ANALYSIS SHOWS A MOST AXIS EXTENDING NWD FROM ERN OK
   ACROSS ERN KS INTO NW MO. A SFC TROUGH/WIND SHIFT IS LOCATED FROM
   NEAR KANSAS CITY MO EXTENDING SWWD INTO NRN OK. ROTATING STORMS HAVE
   DEVELOPED ALONG THIS SFC TROUGH IN A WEAKLY UNSTABLE BUT STRONGLY
   SHEARED ENVIRONMENT. AMPLE SPEED SHEAR EXISTS ON REGIONAL PROFILERS
   FOR SUPERCELL STORMS ALTHOUGH SFC WINDS ARE VEERED ACROSS MOST OF
   THE MD AREA. AN ISOLATED TORNADO THREAT STILL MAY OCCUR WITH THE
   STRONGER ROTATING STORMS. IN ADDITION...STEEP MID-LEVEL LAPSE RATES
   AND UNIDIRECTIONAL WIND PROFILES BELOW 850 MB SHOWN ON FORECAST
   SOUNDINGS LATE THIS AFTERNOON MAY RESULT IN A THREAT FOR HAIL AND
   STRONG GUSTY WINDS OVER THE NEXT FEW HOURS.
