THIS EVENING.

.SHORT TERM...TODAY AND TONIGHT...FORECAST CONFIDENCE MEDIUM.

FIRST ROUND OF STRONG TO SEVERE CONVECTION SHIFTING THROUGH AND
TOWARD THE FORECAST AREA AT THIS TIME. EXPECT MAINLY A DAMAGING
WIND AND FLASH FLOODING RISK WITH THESE STORMS. LOW LEVEL JET
POINTING INTO THE AREA COMBINING WITH GOOD ELEVATED INSTABILITY
AND 40 TO 50 KNOTS OF DEEP LAYER SHEAR TO DRIVE THE STORMS. FLASH
FLOOD WATCH WILL REMAIN IN EFFECT UNTIL NOON FOR MAINLY THE SOUTH
HALF OF THE AREA TO ACCOUNT FOR THIS FIRST BATCH OF CONVECTION.

THIS ROUND OF CONVECTION SHOULD END FROM WEST TO EAST ACROSS THE
AREA BY THE LATE MORNING HOURS. NEXT ROUND OF SEVERE CONVECTION
POSSIBLE WITH COLD FRONTAL PASSAGE THIS AFTERNOON INTO EARLY THIS
EVENING. AIRMASS SHOULD RECOVER FROM CURRENT CONVECTION...AND
ALLOW STRONG INSTABILITY TO DEVELOP. DEEP LAYER SHEAR WILL REMAIN
STRONG IN THE 40 TO 50 KNOT RANGE. GFS TOO FAR NORTH WITH FRONTAL
BOUNDARY...LIKE THE NAM/ECMWF POSITION BETTER. THIS PLACES THE
FRONT NORTHEAST TO SOUTHWEST ACROSS THE FORECAST AREA...WITH THE
SOUTHEAST HALF UNDER THE BEST CHANCES FOR SEVERE WEATHER. LARGE
HAIL AND DAMAGING WINDS...WITH ISOLATED TORNADOES ARE POSSIBLE.

.LONG TERM...THURSDAY THROUGH TUESDAY...FORECAST CONFIDENCE MEDIUM.

QUIET WEATHER RETURNS LATER TONIGHT THROUGH FRIDAY...WITH HIGH
PRESSURE. THUNDER CHANCES RETURN OVER THE WEEKEND...WITH ANOTHER

BOW ECHO IN NE IOWA EXPECTED TO CROSS SRN WI BETWEEN 09Z AND 13Z
AFFECTING ALL TAF SITES WITH SEVERE WIND GUSTS AND IFR/LIFR
CONDITIONS.

AFTER THIS COMPLEX MOVES THROUGH...LOOKING FOR GUSTY SOUTH TO
SOUTHWEST WINDS AHEAD OF COLD FRONT AND THE POTENTIAL OF STRONG TO
SEVERE THUNDERSTORMS WITH THE FRONTAL PASSAGE THIS
AFTERNOON/EVENING WITH IFR/LIFR CONDITIONS. CIGS/VSBYS IMPROVE TO
VFR WITH DRY AIR BEHIND FRONT.

&&

.MARINE...WILL ISSUE A SMALL CRAFT ADVISORY FOR 15Z THROUGH 03Z.
MODEL SOUNDINGS INDICATE MIXING UP TO 30+KT WINDS AT AND ABOVE
1000 FT THAT WILL PRODUCE FREQUENT GUSTS ABOVE CRITERIA. WILL ALSO
BE DEALING WITH SEVERE THUNDERSTORMS EARLY IN FORECAST
PERIOD...WITH DAMAGING WINDS AND LARGE HAIL THE MAIN THREATS WITH
