RECENT RADAR IMAGERY SHOWS REFLECTIVITY IS INCREASING RAPIDLY ALONG
THE LEADING EDGE OF THE CLOUD SHIELD...INDICATIVE OF THE IMPRESSIVE
LARGE SCALE LIFT OCCURRING ATTM. ALTHOUGH THERE IS NO LIGHTNING YET
WITH THE CONVECTION...WIND DAMAGE POTENTIAL MAY BE
INCREASING...GIVEN MID/UPPER LEVEL JET MAXIMA CURRENTLY BEING
SAMPLED BY VWP DATA FROM THE FSD RADAR. LATEST WV SHOWS UPPER LOW
NEAR PIERRE SD AND STRONG SFC CYCLOGENESIS WILL OCCUR ACROSS ERN SD
AS STRONG DYNAMIC FORCING CONTRIBUTES TO LARGE SCALE ASCENT
