AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DULUTH MN
321 AM CDT THU JUN 7 2007

.DISCUSSION...FORECAST FOCUS WILL BE ON SIGNIFICANT SEVERE
WEATHER OUTBREAK FOR TODAY.

DEEP SURFACE LOW...AROUND 979MB WAS IN NORTHEAST SOUTH
DAKOTA EARLY THIS MORNING...AND WILL MOVE NORTHEAST TODAY INTO THE
ARROWHEAD.

THE LLJ WAS AT 50 TO 70 KT AS SEEN ON KDLH AND KMPX KVWPS...AND
AT 750M ON THE BLUE RIVER WIND PROFILER. THE LLJ WILL WEAKEN SOME
TODAY AS THE LOW MOVES CLOSER TO OUR CWA...HOWEVER NAM STILL SHOWS
35-40 KT AT 875MB OVER NORTHWEST WI AND FAR EASTERN MINNESOTA INTO
THE AFTERNOON. SURFACE DEWPOINTS WILL RISE INTO THE LOWER 60S OVER
A GOOD PART OF OUR CWA...ESPECIALLY THE EASTERN HALF. MID LEVEL
LAPSE RATES WILL CLIMB AS WELL...AND CAPE VALUES SHOULD INCREASE
TO 2000-2500J/KG IN SPOTS THAT WARM TO AROUND 80 WITH LOWER 60S
DEWPOINTS. MODELS FORECAST A DRY SLOT TO MOVE UP OVER EASTERN MN
AND WI TODAY...AND SHOULD ALLOW FOR HEATING. A 100KT UPPER JET
SLAMS INTO SOUTHERN MINNESOTA INTO WEST CENTRAL WISCONSIN THIS
AFTERNOON AND EVENING. OUR CWA WILL BE IN AN AREA OF STRONG
DIVERGENCE. PLENTY OF SHEAR WILL BE PRESENT WITH THE UPPER JET
OVER LLJ...CREATING 0-6KM BULK SHEAR OF 55 TO 70KT...AND 0-1KM
SHEAR OF 20-30KT. MUCH OF OUR CWA IS IN HIGH RISK OF SEVERE
STORMS...WHICH IS RARE. ALL PARAMETERS ARE PRESENT FOR A BIG
SEVERE WEATHER DAY...WITH DAMAGING WINDS...LARGE HAIL AND THE
THREAT FOR A TORNADO. BEST TIME FOR SEVERE WILL BE DEPENDANT ON
AMOUNT OF SUNSHINE THAT DEVELOPS...BUT THINGS SHOULD GET GOING
PRETTY QUICKLY THIS AFTERNOON...INTO EARLY EVENING.

CURRENT AREA RADARS SHOW SOME MAINLY ELEVATED STORMS MOVING
THROUGH SOUTHERN MN...HEADING QUICKLY TOWARD OUR SOUTH CENTRAL
COUNTIES. HAIL LOOKS TO BE THE MAIN THREAT WITH THESE STORMS.

SURFACE WINDS WILL ALSO BECOME STRONG ENOUGH TO WARRANT A WIND
ADVISORY FOR NORTHWEST WISCONSIN BY LATE MORNING...INTO THE EARLY
EVENING.

SEVERE STORMS TO CONTINUE INTO THE EVENING...MAINLY OVER FAR
EASTERN MN AND NORTHWEST WISCONSIN AHEAD OF THE SURFACE BOUNDARY.

A RIDGE WILL MAKE A BRIEF APPEARANCE FRIDAY...BRING DRY WEATHER TO
OUR CWA ON GUSTY WEST WINDS.

&&

.AVIATION...NON-CONVECTIVE LLWS WILL CONTINUE ACROSS MUCH OF
AREA THROUGH EARLY MORNING DUE TO A STRONG SOUTHERLY LOW LEVEL
JET. IFR AND MVFR CEILINGS ACROSS NORTHERN MINNESOTA ARE EXPECTED
TO SLOWLY LIFT THIS MORNING FROM SOUTH TO NORTH. THE EXCEPTION IS
AREAS NEAR LAKE SUPERIOR...WHERE THE MARINE LAYER IS EXPECTED TO
KEEP AREAS OF IFR/MVFR CEILINGS THROUGH THE MORNING. IFR/MVFR
CONDITIONS IN ISOLATED THUNDERSTORMS WILL PERSIST THROUGH THE
MORNING AS WELL.

THIS AFTERNOON...AN OUTBREAK OF SEVERE THUNDERSTORMS IS EXPECTED.
NUMEROUS STRONG TO SEVERE THUNDERSTORMS WITH IFR/LIFR CONDITIONS
WILL BE LIKELY.
