ONGOING CONVECTION JUST NORTHEAST OF FORECAST AREA RESIDING ALONG 850MB THETA-E GRADIENT WITH THIS UPGLIDE ZONE FORECAST TO REMAIN ALONG FORECAST AREA PERIPHERY THROUGH THE MORNING. SURFACE BOUNDARY WILL SLIDE THROUGH THE FORECAST AREA MARKING A ZONE OF POOLING HIGHER DEWPOINTS ALONG WITH WEAK SURFACE CONVERGENCE BY AFTERNOON. THIS FORCING ALONG WITH WEAK SYNOPTIC LIFT WITHIN FAVORABLE REGION OF UPPER JET ENTERING BASE OF EASTERN U.S. TROUGH WILL LIKELY SUPPORT A ROUND OF AFTERNOON AND EVENING STORMS. AMPLE INSTABILITY ALONG WITH DEEPLY MIXED SUB CLOUD LAYER WILL PROMOTE STRONG TO SEVERE DOWNBURSTS. A ZONE OF HIGHER PRECIP CHANCES MAY BE DEFINED IN UPDATED FORECASTS AS LOCATION OF SURFACE BOUNDARY BECOMES MORE CLEAR. LOWER DEWPOINTS WILL BE THE MAIN IMPACT FOLLOWING THE BOUNDARY WITH DAYTIME HIGHS ABOVE NORMAL WEDNESDAY AND ESPECIALLY THURSDAY AS SOUTHERLY FLOW RETURNS. HEAT IMPACTS WILL BE LESSENED BY THE LOWER DEWPOINTS ALLOWING MORE EFFICIENT OVERNIGHT COOLING AND LESSER HEAT INDEX VALUES. MODEL CONSENSUS APPEARS TO BE INCREASING TOWARD A MORE PROGRESSIVE FLOW PATTERN DEVELOPING BY LATE WEEK THROUGH THE HOLIDAY WEEKEND. THIS WILL ALLOW SEVERAL DAYS OF MCS ACTIVITY TO DEVELOP ACROSS THE CENTRAL PLAINS...AND POSSIBLY SAG SOUTHWARD INTO THE SOUTHERN PLAINS OVER THE WEEKEND INTO EARLY NEXT WEEK.
