AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DULUTH MN
209 PM CDT MON MAY 29 2006

.DISCUSSION...MAIN FOCUS IS ON CONVECTION THIS EVENING. STORMS ARE
STARTING TO FIRE UP AS OF 2 PM. SEVERE THUNDERSTORM WATCH 419 WAS
JUST ISSUED...AND LOOKS VERY GOOD.

AIRMASS AHEAD OF INCOMING FRONT IS VERY UNSTABLE. DEEP LAYER SHEAR
IS BECOMING MORE FAVORABLE...ESPECIALLY CLOSER TO THE FRONT WHERE
THE STORMS ARE FIRING. MUCAPE IS AROUND 5000 J/KG AND LI ARE
AROUND -11C...SO DEFINITELY NO SHORTAGE OF FUEL FOR THE STORMS.
LOOKING FOR BEST STORMS WHERE CONVERGENCE AND DEEP LAYER SHEAR
IS MAXIMIZED THIS AFTERNOON/EVENING. WILL ADD MENTION OF DAMAGING
WINDS AND LARGE HAIL TO ALL ZONES THIS EVENING...AS THE CURRENT
WATCH MAY BE EXTENDED EAST WITH TIME THIS EVENING.

FOR TONIGHT...SEVERE STORMS ARE LIKELY ALONG AND AHEAD OF THE
FRONT...ESPECIALLY FOR THE EVENING HOURS. THINK THE SCATTERED
STORMS MAY GATHER INTO MORE OF A LIKELY EVENT IN PORTIONS OF THE
SOUTHERN CWA...ESPECIALLY THE TWIN PORTS SOUTH AND EAST. THE FRONT
WILL COOL TEMPS DOWN...BUT IT WILL LIKELY REMAIN MUGGY INTO NW WI
FOR MUCH OF THE NIGHT.

FOR TUESDAY...HIGH PRESSURE WILL BUILD IN...BRINGING DRIER
CONDITIONS FROM WEST TO EAST. COULD STILL BE A BIT OF ACTIVITY IN
NW WI. OTHERWISE...IT LOOKS QUIET WITH SEASONABLE TEMPERATURES.

COULD BE INTERESTING TUESDAY NIGHT AND WEDNESDAY...AS A SHORTWAVE
LIFTS TO THE NE IN SW FLOW. LOW LEVEL MOISTURE RETURNS AS WELL.

OTHER WEAK IMPULSES COULD KICK OFF SOME OTHER SPOTTY ACTIVITY FOR
THE REST OF THE WORK WEEK AS WELL...WITH A LITTLE BETTER CHANCE
FOR THE WEEKEND AS A SYSTEM MOVES IN FROM THE WEST AND RETURN FLOW
PUSHES NORTHWARD AHEAD OF THE FRONT ON A DECENT LLJ.

MOS TEMPS ARE PRETTY CLOSE...AND HAVE FOLLOWED THEM CLOSELY.
