AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LA CROSSE WI
1143 PM CDT MON SEP 7 2015

.SHORT TERM...(TONIGHT THROUGH TUESDAY)
ISSUED AT 305 PM CDT MON SEP 7 2015

A WARM FRONT WAS HUNG UP OVER SOUTHERN IA...STRETCHING INTO SOUTHERN
WI. THE LOW LEVEL JET WILL INCREASE THIS EVENING...PUSHING INTO AND
ACROSS THE BOUNDARY. A LOFT...THE RIGHT ENTRANCE REGION OF A 300 MB
JET STREAK WILL ENHANCE THE AVAILABLE LIFT. HIGH PWS OF 2 INCHES...A
+2 ANOMALY VIA NAEFS...WITH WARM CLOUD DEPTHS OF 4 KFT...AROUND AND
NORTH OF THE FRONT. A RIPPLE IN THE UPPER LEVEL FLOW IS ALSO PROGGED
TO SLIDE FROM THE SOUTHERN PLAINS TO ACROSS THIS FRONT OVERNIGHT.
ALL THIS SHOULD RESULT IN A BLOSSOMING AREA OF SHOWERS AND
THUNDERSTORMS...CAPABLE OF HEAVY RAIN. MESO MODELS TRENDS FAVOR
KEEPING THE BULK OF THE PCPN THREAT ALONG AND SOUTH OF I-90...WITH
THE HEAVY RAIN MOSTLY CONFINED TO IOWA.

MODEL TRENDS HAVE BEEN SLOWING THIS SYSTEM DOWN A BIT OVER THE PAST
FEW DAYS...AND EXPECT PCPN TO LINGER ACROSS THE EAST TUE MORNING.

.LONG TERM...(WEDNESDAY THROUGH MONDAY)
ISSUED AT 305 PM CDT MON SEP 7 2015

DOWNTURN IN THE TEMPERATURES AS LARGE SCALE PATTERN SHIFT FROM
RIDGING TO TROUGH/NORTHWEST FLOW CONTINUES. 850 MB TEMPS ARE
EXPECTED TO DROP FROM 18 C AT 00Z TUE TO 5 C BY 00Z SAT. NAEFS 850
MB TEMP ANOMALIES HOVER NEAR -1 THU THROUGH THE WEEKEND. A DAY OR
TWO WITH HIGHS ONLY IN THE 60S AND LOWS IN THE 40S ARE EXPECTED -
WITH FRI/SAT MORNING LOOKING LIKE THE COOLEST PERIOD.

VARIOUS RIPPLES WILL MOVE ALONG THE NORTHWEST FLOW...WITH PREVIOUS
MODEL RUNS TAKING THEM MOSTLY NORTH/SOUTH OF THE LOCAL AREA...OR
WEAKENING THEM AS THEY MOVED IN. LAST RUN OR TWO THEY HAVE CHANGED
THEIR TUNE. THE GFS/GEM/ECMWF ALL SLIDE AN UPPER LEVEL SHORTWAVE
ACROSS THE UPPER MISSISSIPPI RIVER VALLEY THU/FRI. THAT AND A
RELATED SFC BOUNDARY COULD SPARK SHOWERS/STORMS AS IT MOVES THROUGH.
NOT MUCH INSTABILITY...SO IF PCPN DEVELOPS...MORE ON THE SHOWER THAN
THUNDERSTORM SIDE. SHOWERS COULD LINGER/REDEVELOP ON FRIDAY IN WRAP
AROUND REGION OF THE SFC LOW/FAVORABLE LOW LEVEL LAPSES...MORE SO
ACROSS NORTHERN WI.

.AVIATION...(FOR THE 06Z TAFS THROUGH 06Z TUESDAY NIGHT)
ISSUED AT 1143 PM CDT MON SEP 7 2015

WATCHING THE CONVECTION SLOWLY FILL IN ACROSS NORTHWEST IOWA AND
SOUTHWEST MINNESOTA AHEAD OF THE SHORT WAVE TROUGH COMING OUT OF
NEBRASKA. SEVERAL OF THE HI-RES MESO MODELS NOW SUGGEST THIS AREA
WILL CONTINUE TO EXPAND AND SWING THOUGH THE INTERSTATE 90
CORRIDOR LATE TONIGHT INTO EARLY TUESDAY MORNING. HAVE THUS
TRENDED THE FORECAST TOWARD THESE SOLUTIONS OF BRINGING SOME
LEADING SHOWERS WITH A VCSH BEFORE THE MAIN BAND OF SHOWERS AND
STORMS COMES IN. THE 08.03Z RAP FORECAST SOUNDINGS SUGGEST THE
POTENTIAL FOR IFR CONDITIONS AS THIS COMPLEX OF STORMS MOVES
THROUGH AND IF IT EVOLVES AS THE MESO MODELS SUGGEST...THIS SEEMS
ENTIRELY REALISTIC. THE COMPLEX SHOULD MOVE OUT FAIRLY QUICKLY
TUESDAY MORNING BUT EXPECTING THE IFR CEILINGS TO REMAIN UNTIL
LATE AFTERNOON UNTIL SOME DRIER AIR STARTS TO WORK IN FROM THE
NORTHWEST TO ALLOW THE CONDITIONS TO GO UP TO VFR.
