BOYD && .PREV DISCUSSION... /ISSUED 324 PM CDT MON MAY 17 2010/ DISCUSSION...COMBINATION OF THE UPPER LOW OVER THE OH VALLEY AND THE AFTERNOON HEATING HAS COMBINED TO PRODUCE A SLIGHT RISK OF SEVERE TSTMS THIS AFTERNOON AND EARLY EVENING. 0-3 KM WIND SHEAR IS A RATHER WEAK...BUT B+ IS FAIRLY DECENT. MORNING SOUNDING SHOWS DECENT MOISTURE IN THE SFC TO 700MB ZONE BUT VERY DRY IN THE 700 AND ABOVE AREA. THUS THE HAIL GROWTH ZONE FROM -10C TO -30C IS VERY DRY.
