VALID 220430Z - 220530Z THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 282 CONTINUES. SUMMARY...AN ISOLATED RISK FOR LARGE HAIL/STRONG GUSTS WILL CONTINUE FOR THE NEXT FEW HOURS. DISCUSSION...RADAR MOSAIC OVER THE PAST HOUR HAS SHOWN SEVERAL STORMS CAPABLE OF LARGE HAIL OVER CNTRL AND SRN ND PER MRMS MESH DATA. MUCH OF THE ONGOING TSTM ACTIVITY HAS MOVED THROUGH THE LOW-LEVEL MOIST AXIS THAT EXTENDED FROM S-CNTRL SD NWWD INTO WRN ND. ELY FLOW NEAR THE SURFACE OVER THE ERN HALF OF ND WILL LIKELY ONLY MARGINALLY MOISTEN WITH TIME OWING TO A REINFORCEMENT OF SURFACE HIGH PRESSURE OVER SRN MANITOBA/WRN ONTARIO IN WAKE OF A DEPARTING SHORTWAVE TROUGH OVER ERN ONTARIO. NONETHELESS...AN ADEQUATE FEED OF CONDITIONALLY UNSTABLE PARCELS FROM THE S/SW WILL SUPPORT THE POTENTIAL FOR VIGOROUS UPDRAFTS. THE STRONGER H5 HEIGHT FALLS /60+ M PER 12 HR/ PER EVENING UPPER-AIR ANALYSIS ARE BEGINNING TO OVERSPREAD WRN AND CNTRL ND LATE THIS EVENING. THE STRONG LARGE-SCALE FORCING FOR ASCENT/SHEAR WILL PROBABLY CONTRIBUTE TO AT LEAST A STRONG/ISOLATED SEVERE RISK CONTINUING FOR THE NEXT FEW HOURS. ..SMITH.. 06/22/2016 ...PLEASE SEE WWW.SPC.NOAA.GOV FOR GRAPHIC PRODUCT...
