AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TWIN CITIES/CHANHASSEN MN
1055 PM CDT TUE JUN 25 2013

.SHORT TERM...(TODAY AND TONIGHT)
ISSUED AT 332 PM CDT TUE JUN 25 2013

GOOD NEWS IS TODAY HAS BEEN ANOTHER DAY OF NOT MUCH GOING ON. BAD
NEWS IS IT LEAVES A RATHER UNCERTAIN FORECAST FOR TONIGHT. A
WEAK CONVERGENCE ZONE IS LOCATED FROM CENTRAL ND SEWD INTO ERN SD
AND ALONG THE MN/IA BORDER. A FEW CELLS HAVE FINALLY BEGUN TO
DEVELOP ACROSS SCNTRL MN AROUND 3 PM AND THINK MORE WILL DEVELOP
ALONG AND JUST NORTH OF THIS BOUNDARY INTO THE EVENING HOURS. THEY
SHOULD REMAIN IN A SCATTERED MANNER DUE TO LACK OF SIGNIFICANT
FORCING. THE ATMOSPHERE IS PLENTY UNSTABLE WITH MLCAPE ON THE
ORDER OF 2000-3000 J/KG...BUT IT REMAINS WEAKLY CAPPED FOR NOW
ACCORDING TO SPC MESO ANALYSIS. EFFECTIVE SHEAR OF LESS THAN 20
KTS SHOULD LIMIT A MORE ORGANIZED SEVERE POTENTIAL BUT THE
MAGNITUDE OF THE CAPE WILL HAVE THE ABILITY TO SUSTAIN SHORT-
LIVED CELLS CAPABLE OF WIND DAMAGE AND HAIL. LATER TONIGHT...A
COMPLEX MAY DEVELOP ACROSS THE DAKOTAS AND RIDE DOWN THIS
CONVERGENCE ZONE OVERNIGHT INTO WRN MN...ALBEIT IN A WEAKENING
PHASE.

MODELS DIFFER SIGNIFICANTLY ON CONVECTIVE COVERAGE TONIGHT. HRRR
AND HOPWRF ARE PESSIMISTIC ON COVERAGE THROUGH THE EVENING...BUT
THE OPERATIONAL SYNOPTIC MODELS ARE MUCH MORE BULLISH WITH MET/MAV
POPS STILL IN THE LIKELY RANGE. SIDED WITH THE MESOSCALE MODELS
AND REDUCED POPS ACROSS THE AREA TONIGHT. KEPT 50S NEAR SD BUT
TAPERED THEM OFF TO LOW CHC ACROSS NWRN WI WHERE SHEAR AND FORCING
ARE NON-EXISTENT.

RESIDUAL ACTIVITY MAY BE ONGOING ACROSS PORTIONS OF THE AREA
WEDNESDAY MORNING. A COLD FRONT WILL BE PUSHING THROUGH DURING THE
MORNING/EARLY AFTERNOON AND THE ATMOSPHERE COULD RECOVER ENOUGH
FOR ADDITIONAL DEVELOPMENT ACROSS WRN WI PRIOR TO THE FROPA. KEPT
MODERATE POPS GOING FOR THOSE AREAS.

.LONG TERM...(WEDNESDAY NIGHT THROUGH TUESDAY)
ISSUED AT 332 PM CDT TUE JUN 25 2013

SURFACE BOUNDARY SHOULD BE LOCATED OVER EAST CENTRAL MN BY LATE
WEDNESDAY AFTERNOON...WITH LINGERING THREAT OF STRONG/SEVERE
STORMS INTO WEST CENTRAL WISCONSIN DURING THE EVENING. ACTIVITY
EXPECTED TO WANE THROUGH MIDNIGHT OR SO. THE GFS HOLDS ONTO SOME
INSTABILITY INTO THURSDAY WITH A SMALL CHANCE OF THUNDER LINGERING
THERE. THE REMAINDER OF THE REGION SHOULD REMAIN DRY. THE GFS AND
ECMWF DROP A TROUGH/BACK DOOR COLD FRONT SOUTH AND WEST OF THE
AREA LATER FRIDAY INTO SATURDAY. WILL CARRY SOME CHANCE POPS WITH
THIS FEATURE. SOME MODERATE INSTABILITY NOTED WITH THIS FEATURE AS
WELL...SO THUNDER IS WARRANTED.

THE LONGER TERM A BIT MORE DIFFUSE WITH MODELS HANGING ONTO TO
THE UPPER TROUGH OVER THE GREAT LAKES REGION. WILL CONTINUE WITH
THE SLIGHT CHANCE POPS MONDAY/TUESDAY MAINLY DURING THE DAY FOR
NOW. TEMPERATURES WILL LIKELY RANGE NEAR OR SLIGHTLY BELOW NORMAL
DURING THE EXTENDED PERIOD.

ISSUED AT 1056 PM CDT TUE JUN 25 2013

SHOWERS AND STORMS OVER THE DAKOTAS ARE EXPECTED TO GRADUALLY PUSH INTO
WESTERN MINNESOTA OVERNIGHT. WHILE SOME WEAKENING IS EXPECTED WITH
EASTWARD PROGRESSION...ANTICIPATED COVERAGE STILL WARRANTS A

AND KSTC/. ASSOCIATED CIGS/VSBYS GENERALLY IN THE MVFR CATEGORY
ARE EXPECTED.  MAY SEE SOME REDEVELOPMENT OVER WEST CENTRAL WI
INTO THE AFTERNOON. SOUTHEAST WINDS WILL GRADUALLY SHIFT TO
