AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE DULUTH MN 330 PM CDT WED JUN 6 2012 .SHORT TERM...TONIGHT THROUGH THURSDAY NIGHT AN ELONGATED VORT MAX IN THE NW FLOW WILL REMAIN POSITIONED OVER THE WRN LAKE SUPERIOR REGION OVERNIGHT...GRADUALLY BECOMING REPLACED BY H50 RIDING ADVANCING FROM THE DAKOTAS ON THURSDAY. SCATTERED TO ISOLATED SHRA/TSTMS WILL PERSIST OVERNIGHT...AS WELL AS THURSDAY... DUE TO ELEVATED DEW POINTS IN THE 50S/PWATS AROUND AN INCH...COMBINED WITH H85 WAA AND MID LEVEL OMEGA.

A VERY ISOLATED STORM MAY CONTAIN SEVERE SIZED HAIL THIS EVENING...MAINLY FROM THE INTERNATIONAL FALLS AREA...SOUTH THROUGH THE MILLE LACS LAKE AREA IN THE CORRIDOR OF 60KT 0-6 KM WIND SHEAR AND MAXIMIZED MUCAPE. THE POSSIBILITY FOR A FEW SEVERE STORMS REMAINS SMALL...BUT INCREASES THURSDAY AFTRN OVER THE MN ZONES AS NAM BUFR SOUNDINGS AT KBRD/KINL/KHIB SUGGEST CAPE VALUES INCREASE TO THE 200/250 KJ/KG WITH LI VALUES IN THE NEIGHBORHOOD OF NEGATIVE 5. THE CHANCE FOR MORE WIDESPREAD RAIN...WITH HEAVIER AMOUNTS AROUND A HALF INCH...WILL ARRIVE THURSDAY NIGHT FOR THE WESTERN ZONES AS A CLOSED H85 LOW LIFTS OVER THE WRN DAKOTAS AND SRN MANITOBA.

SFC BDRY WILL DISSIPATE ACROSS CWA SATURDAY ...BELOW AMPLIFYING MID LVL RIDGE. ALTHOUGH CURRENT FCST IS DRY...WILL NEED TO MONITOR FOR ISOLATED RW/TRW ALONG OLD BDR DURING DIURNAL HEATING SATURDAY AFTN. ATTENTION THEN FOCUSES WEST OF CWA SATURDAY EVENING/SUNDAY AS CYCLOGENESIS OCCURS OVER DAKOTAS UNDER EJECTING JET MAX ALONG ERN SIDE OF UPPER TROF. VERY SIGNIFICANT WARM ADVECTION EXPECTED WITH TEMPS/HUMIDITY ABOVE TYPICAL SEASONAL VALUES SUNDAY. LATEST WIND/MSTR PROFILES SUGGEST CONSIDERABLE MIXING OCCURS SUNDAY THROUGH LOWEST 5K FEET WITH RESULT BEING SOME LOWERING OF DEWPOINTS DURING THE AFTN HRS. MAX TEMPS 80S/90S SUNDAY EXCEPT NSHORE WHERE BDRY LYR FLOW OFF LAKE WILL KEEP COOLER CONDITIONS ESPECIALLY ALONG SHORE OF COOK COUNTY. BEST GUESSTIMATE OF TIMING OF FROPA WILL BE SUNDAY NIGHT WITH SHOWERS/STORMS MARCHING EAST AS KINEMATICS INCREASE FROM UPPER TROUGH MOVEMENT.
