1137 AM CDT TUE SEP 9 2014

...HEAVY RAINFALL MOVING IN TONIGHT WITH FLASH FLOODING
POSSIBLE...

.PLAN ON HEAVY RAINFALL TO SPREAD ACROSS MUCH OF THE REGION
TONIGHT WITH WIDESPREAD RAIN AMOUNTS EXPECTED TO BE IN THE 1 TO 3
INCH RANGE. RAINFALL RATES OF 1 TO 2 INCHES PER HOUR COULD
BE SEEN...LEADING TO LOCALLY HIGHER RAINFALL AMOUNTS. SINCE THIS
HEAVIER RAINFALL WILL BE OCCURRING DURING THE NIGHT TIME
HOURS...MOTORISTS SHOULD BE ALERT AND STAY TUNED TO LATEST
CONDITIONS...FORECASTS AND UPDATES. POSSIBLE HAZARDS OF THIS
LOCALIZED HEAVIER RAINFALL INCLUDE LOW VISIBILITY AND POSSIBLE
WASHED OUT ROADWAYS. THIS COULD LEAD TO VERY TREACHEROUS DRIVING
CONDITIONS. 

THERE IS STILL SOME AMOUNT OF UNCERTAINTY OF WHERE THE HEAVIEST
RAINFALL WILL BE FOCUSED...BUT CONFIDENCE IS PRETTY HIGH THAT THE
TIMING OF THE HEAVIER RAINFALL WILL BE LATE THIS EVENING THROUGH
EARLY WEDNESDAY MORNING.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LA CROSSE WI
1127 PM CDT MON SEP 8 2014

.UPDATE...
ISSUED AT 850 PM CDT MON SEP 8 2014

A FEW CLUSTERS OF SHOWERS AND THUNDERSTORMS HAVE BEEN MARCHING
EASTWARD ACROSS THE FORECAST AREA THIS EVENING. THE MAIN
SUPPORTING FEATURES WERE A SHORTWAVE TRACKING ACROSS SOUTHERN
MN...AND A SURGE OF 800-850MB MOISTURE TRANSPORT AHEAD OF THE
WAVE. THE INITIAL STORMS WHEN THEY WERE CLOSER TO I-35 WERE
PRODUCING ANYWHERE FROM 1/2 INCH TO 1 INCH DIAMETER HAIL...AIDED
BY MUCAPE THAT WAS RUNNING 500-1000 J/KG. NOW THAT THE CONVECTION
HAS PUSHED EAST OF THAT MUCAPE AXIS...THE HAIL CONCERN HAS GREATLY
DIMINISHED.

AS THE SHORTWAVE CONTINUES TO PUSH EAST...SO WILL THE SHOWERS AND
EMBEDDED THUNDERSTORMS. IT\S POSSIBLE MUCH OF THE PRECIPITATION
WILL BE EAST OF THE CWA BY 11 PM...AS SUGGESTED BY THE 08.12Z
ECMWF. PLAN ON SPEEDING UP THE EXIT OF THE PRECIPITATION IN THE
FORECAST.

IN THE WAKE OF THE RAIN...DEWPOINTS HAVE BEEN GRADUALLY CLIMBING
ACROSS IOWA AND MINNESOTA AHEAD OF A BROAD LOW PRESSURE SYSTEM
DEVELOPING OVER THE PLAINS. THESE DEWPOINTS SHOULD CONTINUE TO
CLIMB THROUGH THE NIGHT WITH PERSISTENT 925MB MOISTURE TRANSPORT.
11-3.9UM SATELLITE IMAGERY ALSO DEPICTS HOLES IN THE CLOUDS TO
ENHANCE RADIATIONAL COOLING. WINDS ARE GENERALLY FAIRLY LIGHT TOO
ACROSS MN AND IA. ALL THIS SPELLS THE POTENTIAL FOR FOG
DEVELOPMENT WEST OF THE MS RIVER LATER TONIGHT. ADDED AREAS OF FOG
TO THE FORECAST. GREATER POTENTIAL FOR DENSE FOG LOOKS TO RESIDE
WEST OF I-35...THOUGH.

LOOKING AHEAD TO THE TUESDAY NIGHT/WEDNESDAY SYSTEM...TRENDS IN
THE GFS AND ECMWF ARE SUGGESTING A POSSIBLE SLOWER MOVEMENT. THE
08.18Z NAM REMAINS AN OUTLIER BEING TOO PROGRESSIVE AND TOO FAR
NORTH...BUT IT STILL HAS A SLOWING TREND. THIS TREND MEANS THAT
THE FOCUS FOR STRONGER SHOWER/STORM DEVELOPMENT AND HEAVIER QPF
TUESDAY NIGHT COULD END UP MORE OVER IOWA. THE HEAVIER QPF WOULD
APPEAR TO MOVE ACROSS THE FORECAST AREA WEDNESDAY MORNING INSTEAD.
OVERALL THE FORECAST QPF COULD BE A BIT HIGH AND THUS THE
HYDROLOGIC OUTLOOK SEEMS SUFFICIENT FOR NOW. WILL EVALUATE THIS
SYSTEM MORE OVERNIGHT WITH THE 09.00Z DATA.

&&

.SHORT TERM...(THIS EVENING THROUGH TUESDAY)
ISSUED AT 217 PM CDT MON SEP 8 2014

FORECAST CHALLENGES THROUGH TUESDAY INCLUDE CONVECTIVE CHANCES
TONIGHT AND THEN THE POSSIBILITY OF SEVERE THUNDERSTORMS LATE
TUESDAY AFTERNOON AHEAD OF THE NEXT LOW PRESSURE SYSTEM. 08.12Z
MODELS INITIALIZED WITH MINIMAL ERRORS AND ARE IN GOOD OVERALL
AGREEMENT...SO WILL USE A BLENDED MODEL SOLUTION FOR THIS FORECAST
PACKAGE.

FOR TONIGHT...CONVECTIVE CLUSTER CURRENTLY ACROSS CENTRAL IOWA
WILL HAVE MOVED MAINLY SOUTH AND EAST OF THE FORECAST AREA.
HOWEVER... HIGH RESOLUTION MODELS SUGGEST ADDITIONAL DEVELOPMENT
ACROSS NORTH-CENTRAL IOWA AROUND 08.23Z IN RESPONSE TO THE NEXT
SHORT- WAVE ALOFT CURRENTLY ACROSS SOUTH DAKOTA AND INCREASED MID-
LEVEL MOISTURE TRANSPORT. THINK THIS AREA OF SHOWERS AND
THUNDERSTORMS WILL CLIP THE SOUTHERN FORECAST AREA AND WILL
CONFINE POPS TONIGHT TO AREAS ALONG AND SOUTH OF INTERSTATE 90.
TEMPERATURES TONIGHT WILL DROP INTO THE MID 50S TO LOWER 60S WITH
LIGHT SOUTHERLY WINDS. FOG NOT EXPECTED TO BE AN ISSUE WITH
CONVECTIVE DEBRIS CLOUDS AND HIGHER WIND SPEEDS WITHIN THE
NOCTURNAL BOUNDARY LAYER.

ATTENTION TURNS TO TOMORROW AS PACIFIC NORTHWEST TROUGH MOVES INTO
THE NORTHERN ROCKIES AND INITIATES LEE CYCLOGENESIS ALONG THE
COLORADO FRONT RANGE. SURFACE LOW WILL BE NEAR THE COLORADO/
KANSAS BORDER AT 10.00Z AND WITH THE 08.12Z GFS/ECMWF TRENDING A
BIT SLOWER AND FARTHER SOUTH WITH THE LOW TRACK...MOST OF TUESDAY
SHOULD BE DRY. EPICENTER OF THE GREATEST MOISTURE TRANSPORT...
INSTABILITY AND SHEAR THROUGH 10.00Z IS ACROSS EASTERN NEBRASKA
AND CENTRAL/WESTERN IOWA. IF SEVERE THREAT MATERIALIZES FARTHER
EAST ACROSS THE FORECAST AREA IT WILL BE LATE IN THE DAY INTO
TUESDAY EVENING. MUCAPE IS AROUND 500 TO 1500 J/KG WITH 0 TO 6 KM
BULK SHEAR BETWEEN 20 TO 30 KTS AT THIS TIME. STORM MODE IS
LIKELY TO BE SOME KIND OF LINEAR MCS WITH THE PRIMARY THREATS
BEING HEAVY RAIN AND DAMAGING WIND.

.LONG TERM...(TUESDAY NIGHT THROUGH MONDAY)
ISSUED AT 217 PM CDT MON SEP 8 2014

CAPE QUICKLY DISSIPATES AFTER 10.06Z WITH ONLY A FEW HUNDRED J/KG
AVAILABLE OVERNIGHT. HOWEVER...MODEL SOUNDINGS SATURATE TO NEAR
400 HPA WITH PRECIPITABLE WATER VALUES CLIMBING TO NEAR 2 INCHES
(PLUS 2 STANDARD DEVIATIONS). 850 HPA WINDS AHEAD OF THE LOW
INCREASE FROM 40 TO 50 KTS...RESULTING IN VERY STRONG MOISTURE
TRANSPORT ACROSS IOWA INTO SOUTHERN WISCONSIN. STRONG LIFT
ASSOCIATED WITH THIS LOW-LEVEL JET WILL RESULT IN WIDESPREAD
SHOWERS AND THUNDERSTORMS WITH RAINFALL RATES LIKELY EXCEEDING AN
INCH PER HOUR. WIDESPREAD ACCUMULATIONS FROM 1.5 TO 3 INCHES ARE
LIKELY WITH ISOLATED POCKETS UP TO 5 INCHES. FLASH FLOODING AND
RIVER FLOODING WILL BE A CONCERN...BUT WILL ALLOW FOR ONE MORE
MODEL CYCLE TO DETERMINE WHEN/WHERE WATCH HEADLINES MAY BE
NECESSARY. SEE HYDROLOGY DISCUSSION FOR MORE INFORMATION.

SHOWERS AND THUNDERSTORMS WILL MOVE INTO THE NORTHEAST FORECAST
AREA WEDNESDAY MORNING BEFORE DEPARTING IN THE AFTERNOON INTO THE
EVENING. A MUCH COOLER AIR MASS WILL TAKE RESIDENCE ACROSS THE
UPPER MISSISSIPPI RIVER VALLEY BEGINNING WEDNESDAY AND CONTINUE
THROUGH THE UPCOMING WEEKEND. HIGHS FROM THE 60S ACROSS THE
NORTHWEST TO NEAR 70 DEGREES ACROSS THE SOUTHEAST ON WEDNESDAY
WILL DROP INTO 50S REGION-WIDE BY THURSDAY/FRIDAY. NIGHTTIME LOWS
WILL BE HIGHLY DEPENDENT ON CLOUD COVER...BUT WILL EASILY DROP
INTO THE 40S AND POSSIBLY EVEN THE 30S BY FRIDAY NIGHT/SATURDAY
MORNING IF CLEARING OCCURS. WILL NEED TO MONITOR FOR POSSIBLE
FROST HEADLINES. TEMPERATURES TO MODERATE SOMEWHAT OVER THE
WEEKEND WITH INCREASING SOUTHERLY RETURN FLOW ON THE BACKSIDE OF
THE DEPARTING SURFACE HIGH...BUT STILL ONLY INTO THE LOWER TO MID
60S FOR HIGHS AND MID 40S FOR LOWS.

AFTER ANOTHER SHOT OF SHOWERS THURSDAY NIGHT INTO FRIDAY WITH A
SECONDARY SHORT-WAVE ROTATING AROUND THE BASE OF THE PARENT UPPER
LEVEL TROUGH ENCOMPASSING THE CENTRAL CONUS...THE WEEKEND SHOULD
BE MAINLY DRY.

&&

.AVIATION...(FOR THE 06Z TAFS THROUGH 06Z TUESDAY NIGHT)
ISSUED AT 1127 PM CDT MON SEP 8 2014

CONDITIONS ARE VFR AT THE MOMENT. HOWEVER...A FAVORABLE SITUATION
IS SETTING UP FOR LOWERING CEILINGS AND VISIBILITIES OVER THE NEXT
FEW HOURS. A SOUTHERLY BREEZE IS FORECAST TO CONTINUING PULLING
UP MORE MOISTURE OUT OF THE GULF OF MEXICO INTO THE REGION.
MEANWHILE...WARM AIR IS SUGGESTED TO COME IN ALOFT...TRAPPING THE
MOISTURE. RECENT RAIN HELPS TOO. THEREFORE...HAVE CONTINUED IFR
CONDITIONS AT RST WITH MVFR CONDITIONS AT LSE. CEILINGS IN
PARTICULAR COULD NEED TO BE LOWERED MORE...BUT WILL NEED TO WAIT
AND SEE HOW THE STRATUS DEVELOPS. DAYTIME HEATING TOMORROW SHOULD
HELP TO RAISE THE CEILINGS TO MVFR...BUT CONTINUED INFLUX OF
MOISTURE PLUS THE WARM AIR ALOFT HOLDING IN PLACE SHOULD KEEP
THE CEILING CLIMB SLOW. HEADING INTO THE EVENING HOURS...A LARGE
MASS OF SHOWERS AND THUNDERSTORMS SHOULD FIRE OVER IOWA. THESE ARE
EXPECTED TO LIFT TOWARDS RST AND LSE AROUND 03Z...SENDING
VISIBILITIES DOWN TO MVFR. FURTHER LOWERING OF VISIBILITIES AND
CEILINGS IS LIKELY AFTER MIDNIGHT AS MORE OF THE PRECIPITATION
MOVES IN.

.HYDROLOGY...
ISSUED AT 217 PM CDT MON SEP 8 2014

EXPECT WIDESPREAD 1.5 TO 3 INCH RAINFALL AMOUNTS TUESDAY NIGHT
INTO WEDNESDAY WITH LOCALLY HIGHER AMOUNTS IN THE 4 TO 5 INCH
RANGE. WARM CLOUD DEPTHS UP TO 4500 METERS AND PRECIPITABLE WATER
OF AT LEAST 2 INCHES WILL RESULT IN VERY EFFICIENT WARM RAIN
PROCESSES. SHOWERS AND THUNDERSTORMS WILL BE PROGRESSIVE...BUT
WITH HOURLY RAINFALL RATES GREATER THAN AN INCH LIKELY AND FLASH
