Area forecast discussion, Jun 19, 9:25 PM CDT, 2 hours before

AREA FORECAST DISCUSSION...MESOSCALE UPDATE...
NATIONAL WEATHER SERVICE DULUTH MN
925 PM CDT TUE JUN 19 2012

.MESOSCALE UPDATE...CONCERNING ONGOING HEAVY RAINFALL/FLASH FLOODING
AND SEVERE THUNDERSTORM POTENTIAL...

**POTENTIALLY LIFE-THREATENING HEAVY RAINFALL/FLASH FLOOD EVENT
CONTINUES TO EVOLVE ACROSS A LARGE PART OF NORTHERN MINNESOTA**

INITIAL CLUSTER OF STRONG THUNDERSTORMS HAS MOVED OFFSHORE INTO
WESTERN LAKE SUPERIOR AND INTO NW WISCONSIN AS OF 915 PM CDT.
HOWEVER..SURFACE WARM FRONT REMAINS NEARLY STATIONARY FROM NEAR ST
CLOUD..EAST-NORTHEASTWARD TO NEAR SIREN AND HAYWARD..TO JUST SOUTH
OF IRONWOOD.  VERY STRONG LOW LEVEL FRONTOGENESIS IN THE 925-850 MB
LAYER REMAINS ANCHORED PARALLEL TO AND JUST NORTH OF THE SURFACE
FRONT FROM WEST CENTRAL MINNESOTA TO NEAR DULUTH AND IS BEING
ENHANCED BY INCREASING SWRLY LOW LEVEL JET OVER SOUTHERN MN WHICH
CONTINUES TO FOCUS A FEED OF VERY UNSTABLE AIR AND COPIOUS
MOISTURE (PWAT VALUES APPROACHING 2 INCHES) INTO THE FRONTAL
CIRCULATION ZONE. THIS HAS RESULTED IN CONTINUED AND PERSISTENT
THUNDERSTORM REDEVELOPMENT FROM THE ALEXANDRIA AREA TO BRAINERD AND
JUST WEST OF DULUTH.

WHILE THERE APPEARS TO BE AT LEAST SOME SMALL RISK OF ADDITIONAL
SEVERE THUNDERSTORM DEVELOPMENT PER SPC MESOSCALE DISCUSSIONS 1226
AND 1227..THE PRIMARY RISK REMAINS HEAVY RAINFALL AND FLASH FLOODING
OVER A LARGE PORTION OF THE NORTHLAND.  THIS WILL CONTINUE WELL INTO
THE NIGHT IN MOST LOCATIONS.  FLOODING THREAT MAY BE DIMINISHING
SLIGHTLY ACROSS THE IRON RANGE AS LOW LEVEL COOLER OUTFLOW HAS
PUSHED EFFECTIVE FOCUSING BOUNDARY SOUTHWARD INTO THE BRAINERD TO
DULUTH CORRIDOR /CLOSER TO THE WARM FRONT/..WHICH MAY ACT TO FOCUS
HEAVIEST RATES TO THE SOUTH OF THE IRON RANGE CITIES.  AFTER A BRIEF
BREAK IN THE DULUTH AREA AND ALONG THE NORTH SHORE..ADDITIONAL
TSTORMS WITH HEAVY RAIN WILL MOVE BACK ACROSS THIS AREA WITHIN THE
HOUR.

NUMEROUS REPORTS OF FLOODING AND WATER COVERED ROADS HAVE BEEN
RECEIVED FROM ACROSS THE ENTIRE AREA..AND WE CANNOT EMPHASIZE
STRONGLY ENOUGH THE HIGH END NATURE OF THE FLOODING THREAT
OVERNIGHT. THIS IS ESPECIALLY TRUE IN THE DULUTH AREA AND ALONG THE
NORTH SHORE OF LAKE SUPERIOR..WHERE FLOODING THREAT WILL BE ENHANCED
BY 1000-1500 FOOT TERRAIN DROP AND FLOOD WATERS RUSHING DOWN THE
HILL.  STORM SEWERS IN DULUTH HAVE BEEN REPORTED AS EXPLODING FROM
EXCESS WATER PRESSURE AT THE BOTTOM OF THE HILL..ALONG WITH FLOODING
IN THE TUNNELS ON INTERSTATE 35 IN DULUTH.  ADDITIONAL FLOODING IS
ALSO AFFECTING ALL RIVERS AND STREAMS ALONG THE NORTH SHORE..AND ANY
CAMPGROUNDS AND RIVER/ROAD INTERACTIONS ALONG THE NORTH SHORE COULD
BECOME POTENTIAL DEATH TRAPS OVERNIGHT WHEN THE FLOOD THREAT IS
EXACERBATED BY DARKNESS AND LACK OF VISIBILITY.
