AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LA CROSSE WI
344 PM CDT FRI JUN 25 2010

.SHORT TERM...TONIGHT THROUGH SUNDAY NIGHT

THE MAIN CONCERNS FOR THIS TIME PERIOD IS THE SEVERE WEATHER
THREAT FOR THIS EVENING AND SATURDAY NIGHT.

AS FAR AS THE FORECAST FOR TONIGHT...WE MAINLY USED THE MESO
MODELS /HRRR...SPC WRF...AND ARXWRF/ IN THE FORECAST GRIDS. THESE
MODELS HAVE BEEN BY FAR THE MOST CONSISTENT WITH THEIR STORM
EVOLUTION AND THEY MAKE A LOT OF SENSE METEOROLOGICALLY. DURING
THE PAST 3 HOURS...SPC/S MESOSCALE ANALYSIS SHOWS MODERATE SURFACE
FRONTOGENESIS AND DEEP MOISTURE CONVEREGENCE HAS DEVELOPED ACROSS
SOUTHWEST MINNESOTA AND NORTHEAST SOUTH DAKOTA. SOUTH OF THIS
AREA...4000 TO 5000 J/KG MEAN LAYER CAPES HAVE DEVELOPED ACROSS
SOUTHEAST SOUTH DAKOTA...NORTHWEST IOWA...AND EASTERN NEBRASKA. IN
ADDITION...THE EFFECTIVE 0-6 KM SHEAR IS RUNNING BETWEEN 55 AND
65 KNOTS. AS A SHORT WAVE MOVES EAST ACROSS THE DAKOTAS...
SUPERCELL THUNDERSTORMS SHOULD RAPIDLY DEVELOP BETWEEN ABERDEEN
AND SIOUX FALLS AND EXTENDING EAST TO THE TWIN CITIES WITHIN THE
NEXT 2 HOURS. THE HODOGRAPHS IN THESE AREAS ARE FAVORABLE FOR THE
POTENTIAL OF TORNADOES. AS THE COLD POOL DEVELOPS WITH THESE
THUNDERSTORMS...WE ARE EXPECTING THESE SUPERCELLS TO EVOLVE INTO
A SQUALL LINE AND RACE INTO OUR FORECAST AREA AS IT MOVES RAPIDLY
TOWARD THE HIGHER INSTABILITY. WHILE WE ARE NOT THAT UNSTABLE THE
NAM/WRF AND RUC DOES SUGGEST THAT IT WILL BRING THE INSTABILITY
EAST WITH IT. WHILE THE HRRR CONTINUES TO SUGGEST THAT THE BOW OF
THE LINE WILL BE LOCATED ACROSS SOUTHEAST MINNESOTA AND NORTHEAST
IOWA...THE SPC WRF SUGGESTS THAT THIS WILL BE A BIT FURTHER EAST.
AT THIS TIME...IT LOOKS LIKE IT WILL BE MOVING INTO OUR FORECAST
AREA BETWEEN 25.23Z AND 26.00Z...AND EXITING THE AREA SOMEWHERE
AROUND 26.06Z. OVERALL...THE MAIN SEVERE WEATHER THREAT LOOKS TO
BE DAMAGING WINDS. HOWEVER IF THE COLD POOL HAS NOT GREW
SUFFICIENTLY BY THE TIME THE STORMS MOVE INTO SOUTHEAST
MINNESOTA...THERE WILL STILL BE THE POTENTIAL OF A FEW TORNADOES
AND LARGE HAIL. IN ADDITION WITH PRECIPITABLE WATERS VALUES
RUNNING AROUND 1.50 INCHES...THE THUNDERSTORMS WILL BE CAPABLE OF
PRODUCING HEAVY RAIN TOO. HOURLY RAINFALL RATES OF 1 TO 3 INCHES
WOULD BE OUT OF THE QUESTION. ONCE THIS LINE MOVES SOUTH...WE ARE
THINKING THAT THE GREATEST THREAT FOR PRECIPITATION WILL BE OVER
FOR THE NIGHT.

ON SATURDAY...THERE ARE SOME QUESTIONS ON WHERE THE FRONT WILL
BE LOCATED DURING THE AFTERNOON...AND THIS WILL GREATLY AFFECT ON
WHERE THE REDEVELOPMENT MAY HAPPEN. AT THIS TIME...WE SUSPECT THAT
THIS WILL BE SOMEWHERE NEAR THE MINNESOTA AND IOWA BORDER.

ON SATURDAY NIGHT AND SUNDAY MORNING...A COLD FRONT AND UPPER
LEVEL SHORT WAVE WILL MOVE EAST INTO THE AREA. AS THE 850 MB
MOISTURE TRANSPORT CONTINUES TO INTENSIFY DURING THE EVENING...
A MESOSCALE CONVECTIVE COMPLEX IS EXPECTED TO DEVELOP AND THEN
MOVE EAST ACROSS THE FORECAST AREA. THE SHEAR SHOULD BE SUFFICIENT
FOR POSSIBILITY THE BOWING SEGMENTS AND SUPERCELLS. AS A RESULT...
WE EXPECT THE POSSIBILITY OF YET ANOTHER ROUND OF SEVERE WEATHER.
IN ADDITION...THERE WILL THE POTENTIAL OF VERY HEAVY RAIN. HOURLY
RAINFALL RATES OF 1 TO 3 INCHES LOOK POSSIBLE.

.LONG TERM...MONDAY THROUGH FRIDAY

A MAJORITY OF THE 25.00Z GFS AND GEM MODELS ARE IN FAIRLY GOOD
AGREEMENT THAT THE 500 MB RIDGE WILL BUILD ACROSS THE REGION EARLY
IN THIS PERIOD...AND THEN REMAIN IN CONTROL OF THE REGION/S WEATHER
THROUGH THE END OF NEXT WEEK. JUST 2 OF THE 12 GFS ENSEMBLE MEMBERS
SHOWED ANY PRECIPITATION AT ALL AND THAT WAS ASSOCIATED WITH A
BACK DOOR COLD FRONT MOVING THROUGH THE REGION ON TUESDAY
AFTERNOON AND NIGHT. A QUARTER OF THE 16 GEM SOLUTIONS SHOWED SOME
PRECIPITATION ASSOCIATED WITH THIS BACKDOOR COLD FRONT ON
TUESDAY...AND ANOTHER ONE HAD ITS PRECIPITATION CONFINED TO FRIDAY
AND FRIDAY NIGHT AS THE RIDGE BREAKS DOWN AND COLD FRONT
APPROACHES THE REGION. THE LATTER IS SIMILAR TO THE ECMWF
SOLUTION. THE ONLY DIFFERENCE IS THAT THE ECMWF HAS ITS PRECIPITATION
FROM THURSDAY THROUGH FRIDAY NIGHT. WITH SO MANY OF THE ENSEMBLE
RUNS DRY...IT WAS THE CONSENSUS TO LEAVE THIS ENTIRE PERIOD DRY
FOR NOW.

&&

.AVIATION...TONIGHT THROUGH SATURDAY MORNING

ONGOING CONVECTION OVER CENTRAL MINNESOTA SLOWLY WEAKENING AS IT
HEADS SOUTHEAST TOWARD THE AREA. DID MENTION VCTS FOR KRST AROUND
20Z BASED ON CURRENT RADAR TRENDS. WATER VAPOR SHOWING SHORTWAVE AND
SURFACE LOW OVER THE HIGH PLAINS TRACKING EASTWARD. LAPS INDICATING
MIXED LAYER CAPES ALREADY 1000-2000 J/KG ACROSS SOUTHWEST MINNESOTA
AND NORTHWEST IOWA. AS CAP WEAKENS WOULD EXPECT CONVECTION TO
INITIATE IN THIS AREA BETWEEN 22Z-00Z AND EVOLVE INTO A LINEAR
COMPLEX AS IT PUSHES EAST-SOUTHEAST. DID TRY AND PROVIDE SOME TIMING
TO THE TAFS FOR THE ARRIVAL OF THIS LINE...01Z-03Z AT KRST AND
02-04Z AT KLSE AND MENTIONED WIND GUSTS TO 50 KNOTS. VFR CONDITIONS
EXPECTED...EXCEPT WITHIN THE STORMS WHERE IFR CEILINGS AND
VISIBILITIES ARE LIKELY.

DID REMOVE MENTION OF RAIN AFTER ABOUT 07Z-08Z TONIGHT WITH JUST
HIGH CLOUDS FOR THE REMAINDER OF THE PERIOD THROUGH 18Z SATURDAY.
