AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LA CROSSE WI
315 AM CDT WED JUL 14 2010

.SHORT TERM...TODAY THROUGH FRIDAY NIGHT

MAIN FORECAST CONCERN SQUARELY ON SEVERE THREAT THIS AFTERNOON INTO
TONIGHT. ALSO OF CONCERN WILL BE VERY WARM AND HUMID AIRMASS
CREATING HEAT ISSUES.

SURFACE MAP THIS MORNING HAS STRONG SURFACE CYCLOGENESIS OVER WESTERN
SD WITH SURFACE LOW ALREADY AT 996MB. A WARM FRONT EXTENDED FROM THIS
LOW INTO WESTERN IA AND MO. LEADING EDGE OF WAA/ISENTROPIC
LIFT/MOISTURE TRANSPORT CENTERED AROUND 850MB LAYER ACROSS THIS FRONTAL
BOUNDARY PRODUCING SCATTERED-BROKEN DECK OF 4-8KFT CLOUD MAINLY WEST
OF THE MISSISSIPPI AT THIS TIME. RADAR MOSAIC SHOWING AN OCCASIONAL
LIGHT ECHOES MOVING ACROSS SOUTHWEST MN INTO EAST-CENTRAL MN WITH
THIS LIFT/MOISTURE TRANSPORT. MEANWHILE...FURTHER NORTHWEST AT THE
NOSE OF THE STRONGEST MOISTURE TRANSPORT...BIG CONVECTION TAKING
PLACE ACROSS ND WITH A HISTORY OF LARGE HAIL.

14.00Z SUITE OF DETERMINISTIC MODELS AND THE 13.21Z SREF ALL IN GOOD
AGREEMENT THAT THE AREA WILL LIKELY SEE A SEVERE OUTBREAK BY LATER
THIS AFTERNOON...LASTING INTO THE EVENING HOURS. THE NAM DOES
HOWEVER LOCK ONTO SOME MORNING CONVECTION TAKING PLACE ACROSS THE
AREA LATER THIS MORNING ON EASTERN PERIPHERY OF STRONG AXIS OF
925-850MB TRANSPORT AND LIFT AHEAD OF THE WARM FRONT. THIS IS THE
ONLY MODEL DOING THIS. WITH CAP STRENGTHENING TODAY...HAVE DOUBTS
ABOUT THIS DEEPER CONVECTION SO WILL OPT TO MAINTAIN DRY FORECAST
THROUGH THIS MORNING. OTHERWISE...VERY MUGGY AIRMASS HEADED INTO THE
AREA BEHIND THE WARM FRONT PUSHING THROUGH TODAY WITH DEW POINTS
INCREASING INTO THE MID AND UPPER 70S THIS AFTERNOON. THIS...COUPLED
WITH TEMPERATURES CLIMBING INTO THE UPPER 80S TO A FEW LOWER
90S...IS EXPECTED TO PRODUCE HEAT INDICES IN THE 100 TO AS HIGH AS
108 THIS AFTERNOON INTO THE EARLY EVENING. AS SUCH...HAVE OPTED TO
GO WITH A HEAT ADVISORY TODAY FROM NOON THROUGH 7 PM FOR MAJORITY OF
THE FORECAST AREA. THE OTHER SIDE OF THIS VERY WARM AND MUGGY
AIRMASS IS THAT IT WILL SET UP FAVORABLE CONDITIONS FOR SEVERE
THUNDERSTORMS LATE THIS AFTERNOON THROUGH THIS EVENING.
MODERATE-STRONG CAP TO PERSIST THROUGH MUCH OF THE AFTERNOON ACROSS
THE AREA AS EVIDENCED BY 120-180J/KG CIN BY THE NAM AT 21Z.
HOWEVER...ONGOING STRONG-SEVERE THUNDERSTORMS EXPECTED TODAY ACROSS
PORTIONS OF NORTHERN/CENTRAL MN WILL BE EDGING SOUTHEASTWARD TOWARD
THE AREA ON THE EDGE OF THE CAP AND INCREASING MID-LEVEL LAPSE RATES
AS ANOMALOUSLY DEEP MID-LEVEL LOW MAKES ITS WAY ALONG THE
U.S./CANADIAN BORDER. THIS PUSHES ASSOCIATED COLD FRONT AND
ANTICIPATED LINE OF STRONG-SEVERE THUNDERSTORMS INTO OUR AREA BY
LATE THIS AFTERNOON...MAINLY AFTER 21Z AS 0-3 KM MUCAPE INCREASES
INTO THE 3000-5000J/KG RANGE ALONG WITH 45-55KT BULK SHEAR. THERE IS
STILL SOME QUESTION AS TO THE MAIN SEVERE MODE. THE NAM IS
INDICATING THAT A SURFACE LOW AND WARM FRONT IN THE VICINITY COULD
PRODUCE STRONG HELICITY/DISCRETE SUPERCELL AND TORNADO POTENTIAL
ALONG AND NORTH OF I-94...EVENTUALLY MELDING INTO LINEAR SYSTEM
GOING INTO THE EVENING AS THE COLD FRONT /STEEPENING MID-LEVEL LAPSE
RATES PUSHES FURTHER SOUTHEAST INTO THE AREA. THE GFS AND ECMWF
APPEAR TO PUSH THE WARM FRONT FURTHER NORTH AND WOULD PRODUCE A
MAINLY LINEAR COMPLEX OF STORMS WITH DAMAGING WINDS AND LARGE HAIL
BEING THE MAIN THREAT ALONG TH COLD FRONT WITH ISOLATED TORNADOES
POSSIBLE. EITHER WAY...LOOKS LIKE QUITE A NASTY SEVERE THREAT
SETTING UP FOR THE AREA LATER THIS AFTERNOON INTO THIS EVENING.
ALSO...ADDING TO THE SEVERE THREAT WILL BE POTENTIAL FOR WATER
ISSUES WITH VERY HIGH PRECIPITABLE WATER VALUES AROUND 2.5 INCHES.
HAVE INCLUDED A HYDROLOGY SECTION BELOW TO DISCUSS THIS IMPACT
FURTHER.

THE COLD FRONT AND BULK OF STRONG-SEVERE THUNDERSTORM ACTIVITY
APPEARS TO PUSH SOUTHEAST OF THE AREA AFTER MIDNIGHT BUT WANING
THUNDERSTORM ACTIVITY LINGERING ACROSS SOUTHEAST PORTIONS OF THE
FORECAST AREA THROUGH EARLY MORNING HOURS.

RELATIVELY QUIET CONDITIONS THEN EXPECTED THURSDAY THROUGH FRIDAY AS
HIGH PRESSURE BUILDS IN FROM THE PLAINS.

.LONG TERM...SATURDAY THROUGH TUESDAY

THE NEXT CHANCE OF SHOWERS/THUNDERSTORMS LOOKS TO BE FROM SATURDAY
NIGHT INTO EARLY SUNDAY AS 14.00Z GFS/ECMWF SHOW ANOTHER VIGOROUS
MID-LEVEL SHORTWAVE TROUGH MOVING ACROSS SOUTHERN CANADA/UPPER
MIDWEST. A WARM FRONT PUSHING NORTHEAST OUT OF THE PLAINS WILL GIVE
THE AREA ANOTHER CHANCE OF SHOWERS AND THUNDERSTORMS. CURRENTLY
CARRYING CHANCES ACROSS NORTHEAST IA...BUT MAY HAVE TO BE EXTENDED
NORTHWARD INTO SOUTHEAST MN DEPENDING ON MCS TRACK.

&&

.AVIATION...TODAY AND TONIGHT

MULTIPLE THUNDERSTORM CONCERNS EXIST...INCLUDING SEVERE WEATHER.
FIRST FOR THIS MORNING...A WARM AND MOIST AIRMASS MOVING NORTHEAST
FROM WESTERN IA COULD TRIGGER A FEW SHOWERS AND THUNDERSTORMS FROM A
4000-6000 FT CEILING DECK AT BOTH TAF SITES. 06Z TAF ISSUANCE
INCLUDED A CB MENTION AT KRST BETWEEN 09-14Z GIVEN A LITTLE HIGHER
CONFIDENCE OF PRECIPITATION OCCURRING THERE VERSUS KLSE. BOTH TAF
SITES COULD SEE SOME MVFR TO VFR BR FROM THE MOISTURE MOVING IN TOO.
MUCH OF THE REST OF THE DAY SHOULD FEATURE SCT TO POSSIBLY BKN MVFR
TO VFR BASED CUMULUS CLOUDS...WITH A VERY HUMID AIRMASS IN PLACE.
LOOK FOR GUSTY SOUTH WINDS AS WELL. LATE IN THE AFTERNOON THROUGH
THE EVENING...A COLD FRONT IS FORECAST TO CROSS THE TAF SITES.
THUNDERSTORMS ARE EXPECTED TO INITIATE ON THIS FRONT...LIKELY
BECOMING SEVERE QUICKLY. KRST WOULD LIKELY BE AFFECTED SOMETIME
BETWEEN 20-24Z WITH KLSE BETWEEN 22-02Z. FUTURE TAF FORECASTS WILL
BE ABLE TO PIN DOWN TIMING MORE...IN ADDITION TO WHAT SEVERE WEATHER
HAZARDS COULD POSSIBLY IMPACT THE SITES. GRADUAL CLEARING SHOULD
FOLLOW BEHIND THE STORMS AND FRONT FOR THE REST OF THE NIGHT. NOT
CONCERNED ABOUT FOG DEVELOPMENT LATE TONIGHT FROM THE EXPECTED RAIN
DUE TO DRY AIR MOVING IN AND WEST WINDS STAYING UP.

&&

.HYDROLOGY...

VERY MOIST AIRMASS WILL BE IN PLACE AS THE COLD FRONT TRAVERSES THE
REGION. STORMS THAT FORM AHEAD OF THE FRONT LOOK TO BE
SLOW-MOVING... WITH THE STORM MOTION TO THE NORTHEAST...BUT
DEVELOPMENT TO THE SOUTH AND SOUTHWEST INTO THE BETTER CAPE AND
MOISTURE FEED. MOISTURE POOLING ALONG THE BOUNDARY...WITH MODEL
PRECIPITABLE WATER OVER 2 INCHES...AND AROUND 200 PERCENT OF
NORMAL. THAT BEING SAID...WHILE INDIVIDUAL STORMS MAY PRODUCE
LOCALLY HEAVY RAINFALL...THINKING IS THE OVERALL FRONTAL MOVEMENT
WILL KEEP THE STORMS PROGRESSIVE...THEREBY LIMITING THE EXTENT OF
ANY TRAINING OR REPEATED CELLS OVER THE SAME AREA. MOST MODEL
DEPICTIONS SUPPORT THIS WITH THE COLD POOL HELPING PUSH STORMS
ALONG. THUS DO NOT ANTICIPATE THE NEED FOR ANY WATCH OR OUTLOOK AT
THIS TIME.
