Area forecast discussion, Jul 13, 12:17 AM CDT, 2 hours 22 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LA CROSSE WI
1217 AM CDT MON JUL 13 2015

.UPDATE...
ISSUED AT 640 PM CDT SUN JUL 12 2015

A TORNADO WATCH HAS BEEN ISSUED FOR BUFFALO/WABASHA/OLMSTED/
DODGE/MOWER COUNTIES UNTIL 1 AM CDT. CURRENTLY WATCHING A LARGE
CLUSTER OF SEVERE THUNDERSTORMS ACROSS WEST-CENTRAL MN...WHICH ARE
STILL EXPECTED TO GROW UPSCALE INTO A COLD-POOL DOMINATED LINEAR
CONVECTIVE SYSTEM AND MOVE ACROSS THE UPPER MS RIVER VALLEY
FROM ROUGHLY 11 PM THIS EVENING UNTIL 6 AM MONDAY MORNING. PRIOR
TO THIS LINE OF STORMS...CANNOT RULE OUT AN ISOLATED SEVERE
THUNDERSTORM WITH A TORNADO THREAT ACROSS SOUTHEAST MN...BUT
PRIMARY THREATS FOR THE NIGHT CONTINUE TO BE NON-TORNADIC
DAMAGING WIND AND LARGE HAIL WITH ANY LINEAR SYSTEMS.

&&

.SHORT TERM...(THIS EVENING THROUGH MONDAY)
ISSUED AT 342 PM CDT SUN JUL 12 2015

MAIN FORECAST CONCERNS ARE ON SEVERE THUNDERSTORM POTENTIAL THIS
EVENING INTO THE OVERNIGHT. FOCUS THEN TURNS TO THE POSSIBILITY OF
SCATTERED STRONG TO SEVERE STORMS MONDAY AFTERNOON MAINLY IN
WISCONSIN.

A ROUND OF SEVERE STORMS IS LIKELY TONIGHT BUT EXACTLY WHERE THESE
STORMS OCCUR WILL CONTINUE TO BE REFINED AS WE GO INTO THE EARLY
EVENING AND SEE EXACTLY WHERE STORMS INITIATE NORTHWEST OF THE
FORECAST AREA. THE LATEST SPC MESOSCALE ANALYSIS SHOWS STRONG
INSTABILITY ALONG AND WEST OF THE MISSISSIPPI RIVER THIS
AFTERNOON WITH SURFACE BASED CAPE VALUES RANGING FROM 2500 J/KG
NEAR THE MISSISSIPPI RIVER TO 5000 J/KG PLUS OVER SOUTHWEST INTO
WEST CENTRAL MINNESOTA. LATEST THINKING...WE SHOULD SEE STORMS
DEVELOP NEAR A TRIPLE POINT OVER WESTCENTRAL MINNESOTA INTO
SOUTHEAST NORTH DAKOTA/NORTHEAST SOUTH DAKOTA...THEN TRACK
EAST/SOUTHEAST THIS EVENING. WATER VAPOR SHOWS A SHORTWAVE MOVING
INTO THESE AREAS WITH SOME CONVECTION ALREADY GOING. MESOSCALE
MODELS CONTINUE TO SHOW VARYING SOLUTIONS ON HOW THE
CONVECTION/STORMS WILL EVOLVE AS THEY HEAD SOUTHEAST TOWARD THE
FORECAST AREA...AND WHETHER OR NOT WE WOULD SEE ANY DEVELOPMENT
ACROSS SOUTHWEST MINNESOTA BEFORE THIS BATCH OF STORMS ARRIVES.
GIVEN CAPE AND SHEAR PROFILES THERE IS THE POTENTIAL FOR A
WIDESPREAD DAMAGING WIND EVENT...DEPENDING ON HOW THE STORMS
EVOLVE. 0-1 KM BULK SHEAR VALUES ARE NOT ALL THAT IMPRESSIVE
TONIGHT BUT IF WE SEE A STRONG BOW ECHO DEVELOP WE CANNOT RULE OUT
AN ISOLATED TORNADO OR TWO. THE STORMS SHOULD BE MOVING QUICKLY
BUT WE COULD STILL SEE A QUICK 1 TO 2 INCHES OF RAINFALL WHICH MAY
LEAD TO LOCALIZED FLOODING IN URBAN AND POOR DRAINAGE AREAS. GIVEN
STEEP LAPSE RATES ALOFT...WE MAY EVEN SEE SOME LARGE HAIL
ESPECIALLY IF THE STORMS ARE MORE OF A BROKEN LINE OF INDIVIDUAL
CELLS. THE STORMS ARE EXPECTED TO MOVE INTO WEST CENTRAL
WISCONSIN...SOUTHEAST MINNESOTA...AND PORTIONS OF NORTHEAST IOWA
AFTER 9 PM THEN PUSH EAST AND FINALLY EXIT THE FORECAST AREA BY 3
AM. THIS TIMING MAY CHANGE DEPENDING ON THE STORM EVOLUTION.

AFTER TONIGHTS  STORMS...FOCUS THEN TURNS TO THE POSSIBILITY OF
STRONG TO SEVERE STORMS ON MONDAY. THE NAM IS INDICATING 0-1 KM
MUCAPE VALUES MAY CLIMB INTO THE 2000-4000 J/KG RANGE 0-6 KM BULK
SHEAR VALUES AR EXPECTED TO BE IN THE 40-45 KT RANGE WITH MUCH OF
THIS SHEAR MAINLY IN THE 0-3 KM LAYER. IF STORMS DEVELOP THEY
WOULD BE CAPABLE OF PRODUCING LARGE HAIL AND DAMAGING WINDS. THE
MAJOR CAVEAT IS A CAP THAT PERSISTS IN MOST OF THE NAM FORECAST
SOUNDINGS ACROSS THE FORECAST AREA.

.LONG TERM...(MONDAY NIGHT THROUGH SUNDAY)
ISSUED AT 342 PM CDT SUN JUL 12 2015

NORTHWEST FLOW ALOFT IS THEN EXPECTED ACROSS THE UPPER MISSISSIPPI
RIVER VALLEY MONDAY NIGHT INTO TUESDAY WITH A FEW MORE WEAK
SHORTWAVE MOVING THROUGH. THESE WAVES COULD INTERACT WITH
INSTABILITY ACROSS THE REGION TO PRODUCE SHOWERS AND STORMS. WE
SHOULD THEN SEE A BREAK IN SHOWER AND THUNDERSTORMS CHANCES TUESDAY
NIGHT INTO EARLY WEDNESDAY AS RIDGING MOVES IN ALOFT. FLOW THEN
TRANSITIONS TO ZONAL BY LATE IN THE WEEK WITH SEVERAL SHORTWAVES
MOVING THROUGH BRINING CONTINUED CHANCES FOR SHOWERS AND STORMS.
GIVEN THE UNCERTAINTY ON WHEN THESE WAVES WOULD ARRIVE HAVE LEANED
TOWARD A MODEL CONSENSUS BLEND FROM LATE IN THE WEEK INTO NEXT
WEEKEND. AFTER A BRIEF COOL DOWN THIS WEEK WE SHOULD SEE HIGH
TEMPERATURES RETURN TOT HE MID TO UPPER 80S FRIDAY INTO SATURDAY.

&&

.AVIATION...(FOR THE 06Z TAFS THROUGH 06Z MONDAY NIGHT)
ISSUED AT 1217 AM CDT MON JUL 13 2015

LINE OF THUNDERSTORMS...SOME OF WHICH MAY BE STRONG TO SEVERE...
FROM NEAR KGYL TO KEAU TO KASX...WILL CONTINUE TO MOVE SOUTH AND
EAST THROUGH THE NIGHT. OVERALL TREND HAS BEEN A WEAKENING
LINE...SO DROPPED WIND GUSTS TO AROUND 35 KTS...BUT MAINTAINED IFR
CEILINGS/VISIBILITY WITH THUNDERSTORMS. IFR CONDITIONS WILL BE
SHORT-LIVED...BUT A BIT UNCERTAIN WITH HOW FAST CONDITIONS WILL
IMPROVE BEHIND THE LINE. COULD SEE SOME LINGERING MVFR CEILINGS/
VISIBILITY IN MIST BEFORE AN EVENTUAL RETURN TO VFR MONDAY
MORNING. STILL A CHANCE FOR SHOWERS/THUNDERSTORMS MONDAY
AFTERNOON...BUT NOT ENOUGH CONFIDENCE TO INCLUDE IN 13.06Z TAFS.
OTHERWISE...EXPECT MOSTLY VFR CONDITIONS THROUGH MONDAY WITH LIGHT
SOUTHERLY WINDS SHIFTING TO THE WEST AFTER SURFACE TROUGH PASSAGE.
