     DAY 1 CONVECTIVE OUTLOOK       NWS STORM PREDICTION CENTER NORMAN OK     1127 AM CDT WED JUN 20 2012          VALID 201630Z - 211200Z          ...THERE IS A SLGT RISK OF SVR TSTMS ACROSS PARTS OF WI...MN...AND     IA...          ...THERE IS A SLGT RISK OF SVR TSTMS OVER PARTS OF SOUTHERN KS AND     THE TX/OK PANHANDLES...          ...MN/WI/IA...     AN EXPANSIVE UPPER RIDGE IS PRESENT TODAY OVER MOST OF THE EASTERN     AND SOUTHERN STATES...WHILE AN UPPER TROUGH DOMINATES THE WEATHER     OVER THE NORTHERN PLAINS.  THE PRIMARY SURFACE BOUNDARY ASSOCIATED     WITH THE TROUGH EXTENDS FROM NORTHWEST WI INTO CENTRAL NEB...THEN     SOUTHWESTWARD INTO THE OK/TX PANHANDLES.  THIS BOUNDARY WILL BE THE     FOCUS FOR SCATTERED THUNDERSTORMS THIS AFTERNOON AND EVENING.            A FAST-MOVING CLUSTER OF STORMS NEAR DLH WILL MOVE INTO LAKE     SUPERIOR SOON.  HOWEVER...CONVERGENCE ALONG THE TRAILING SURFACE     BOUNDARY WILL LIKELY RESULT IN SCATTERED THUNDERSTORM DEVELOPMENT     OVER PARTS OF WESTERN WI...SOUTHEAST MN...AND EASTERN IA BY MID/LATE     AFTERNOON.  THE AIR MASS AHEAD OF THE BOUNDARY IS QUITE MOIST AND     WILL BECOME MODERATELY UNSTABLE WITH MLCAPE VALUES OVER 2000 J/KG.      STEERING FLOW PARALLEL WITH THE BOUNDARY WILL LIKELY RESULT IN A     LONG SQUALL LINE THIS EVENING ALONG THE BOUNDARY AS IT MOVES ACROSS     THE SLIGHT RISK AREA.  LAPSE RATES ARE NOT PARTICULARLY STEEP...BUT     THE POTENTIAL EXISTS FOR A FEW BOW/LEWP STRUCTURES ALONG THE LINE     RESULTING IN CORRIDORS OF DAMAGING WINDS AND HAIL.          ...KS/OK/TX...     MORNING SURFACE ANALYSES SHOW A COLD FRONT SURGING SOUTHWARD ALONG     THE CENTRAL HIGH PLAINS.  THIS BOUNDARY WILL LIKELY EXTEND FROM     NORTHEAST NM INTO SOUTH-CENTRAL KS BY LATE AFTERNOON.  FULL HEATING     WILL RESULT IN DEEP MIXING AND HELP WEAKEN THE CAP...RESULTING IN     SCATTERED THUNDERSTORM DEVELOPMENT ALONG THE FRONT.  30+ DEGREE     SURFACE T-TD SPREADS...STEEP LOW LEVEL LAPSE RATES...MLCAPE VALUES     OVER 2000 J/KG...AND STRENGTHENING NORTHWESTERLY MID LEVEL WINDS     WILL COMBINE TO YIELD A RISK OF ISOLATED SEVERE STORMS.  LOCALLY     DAMAGING WINDS WILL BE THE MAIN THREAT...ALTHOUGH HAIL IS ALSO     POSSIBLE IN THE STRONGEST STORMS.          ...NY/VT...     MODELS DIFFER ON EXTENT OF CONVECTION THAT WILL AFFECT NY/NEW     ENGLAND THIS AFTERNOON AND EVENING.  THE AREA MOST LIKELY TO SEE A     FEW THUNDERSTORMS WILL BE ACROSS NORTHEAST NY AND NORTHERN VT.  IF     STORMS CAN FORM IN THIS AREA...RATHER STRONG NORTHWESTERLY MID/UPPER     LEVEL FLOW COMBINED WITH MODERATE INSTABILITY WILL POSE A RISK OF A     FEW STRONG/SEVERE STORMS CAPABLE OF GUSTY WINDS AND HAIL.          ..HART/MOSIER.. 06/20/2012          CLICK TO GET WUUS01 PTSDY1 PRODUCT       NOTE: THE NEXT DAY 1 OUTLOOK IS SCHEDULED BY 2000Z     CURRENT UTC TIME: 1646Z (11:46AM), RELOAD THIS PAGE TO UPDATE THE TIME
