AREA FORECAST DISCUSSION...MESOSCALE UPDATE... NATIONAL WEATHER SERVICE DULUTH MN 600 PM CDT THU JUN 18 2009 .MESOSCALE UPDATE...CONCERNING SEVERE THUNDERSTORM POTENTIAL IN EAST CENTRAL MINNESOTA AND NOTHWEST WISCONSIN... IT APPEARS THAT THE THREAT FOR ORGANIZED STRONG TO SEVERE THUNDERSTORMS WILL SLOWLY INCREASE IN AREAS FROM LAKE MILLE LACS TO HINCKLEY AND PINE CITY... AND EASTWARD ACROSS AT LEAST THE SOUTHERN PORTION OF NORTHWEST WISCONSIN THROUGH 9 PM. UPSTREAM SHORT WAVE TROF AXIS CONTINUES TO PROGRESS STEADILY EASTWARD ACROSS THE DAKOTAS LATE THIS AFTERNOON. AHEAD OF THIS FEATURE..SURFACE PRESSURE FALLS AND RATHER ROBUST INSOLATION HAS ALLOWED THE SURFACE WARM FRONT TO TRANSLATE NORTHWARD TO AN AXIS ROUGHLY FROM JUST NORTH OF ST CLOUD..EASTWARD TO THE HINCKLEY/PINE CITY AREA..AND THE SIREN/HAYWARD/PARK FALLS CORRIDOR. SEVERE STORMS/SUPERCELLS HAVE BEEN ONGOING FOR SEVERAL HOURS INVOF THE SFC WARM FRONT BETWEEN ALEXANDRIA AND LITTLE FALLS..AND THERE APPEARS TO BE AN INCREASING RISK OF THESE STORMS CONTINUING AN EASTWARD PROPAGATION ALONG OR JUST NORTH OF THE SFC WARM FRONT OVER THE NEXT SEVERAL HOURS AS ALL AVAILABLE SHORT RANGE GUIDANCE SUGGESTS A LOW LEVEL JET INCREASING INTO THE 30-40 KT RANGE AHEAD OF THIS ACTIVITY INTO THE WARM FRONTAL ZONE..WHICH WOULD SUPPORT INCREASING MESOSCALE ASCENT AND CONVECTIVE MAINTENANCE. ALTHOUGH SIGNIFICANT DESTABILIZATION HAS OCCURRED WITHIN THIS CORRIDOR OVER THE PAST 3-4 HOURS /MUCAPE INCREASING BY 800-1200 J/KG/..DEEP LAYER SHEAR REMAINS SOMEWHAT WEAK IN THE 30-35 KT RANGE. IN ADDITION..IT APPEARS THAT THE BOUNDARY LAYER MAY NOT BE QUITE AS DEEPLY MIXED IN THIS AREA..WITH THE MOST UNSTABLE PARCELS AROUND 2-3 KFT AGL. THUS..STORMS MAY REMAIN SLIGHTLY ELEVATED. NONETHELESS..IF STORMS CAN MANAGE TO WORK INTO THE SOUTHERN SECTIONS OF THE DULUTH CWA..AND GIVEN UPSTREAM OBSERVED SUPERCELLULAR STRUCTURES..2 INCH HAIL AND WINDS UP TO 65 MPH APPEAR WELL WITHIN THE RANGE OF POSSIBILITIES WITH THE STRONGEST UPDRAFTS. THE TORNADO POTENTIAL MAY BE LIMITED BY NEAR-SURFACE PARCELS STILL FIGHTING SUBSTANTIAL CIN..AND EVENTUAL EVOLUTION INTO MCS/MULTICELL MODE. HOWEVER..LOW LEVEL SHEAR WILL ALSO INCREASE SIGNIFICANTLY WITH THE ONSET OF THE LOW LEVEL JET..SO WE WILL BE MONITORING THIS CLOSELY. MILLER && .DLH WATCHES/WARNINGS/ADVISORIES... MN...NONE.
