What was reported inside it

Time	Report	Where	Remark
Aug 4, 5:35 PM CDT	TSTM WND GST 42	Hazel Green, WI	NO WIND DAMAGE REPORTED YET. SEVERAL OTHER REPORTS AROUND THE COUNTY IN THE SAME WINDSPEED RANGE.

Local storm reports filed while the alert was in force, from inside its polygon or its counties.

Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

The nearest sounding before it

Davenport, (KDVN), launched 12:00Z, 10.2 hours before the alert went out and 110 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

Skew-T log-p

Temperature in red, dew point in green, the mixed-layer parcel dashed.

Area forecast discussion, Aug 4, 2:57 PM CDT, 2 hours 14 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LA CROSSE WI
257 PM CDT MON AUG 4 2008

.SHORT TERM...TONIGHT THROUGH FRIDAY

MAIN FORECAST CONCERNS ARE PRECIPITATION CHANCES THIS EVENING
INTO TUESDAY.

LATEST WATER VAPOR SATELLITE IMAGERY INDICATED SHORTWAVE TROUGH
OVER SOUTHERN MINNESOTA AND SOUTHWESTERN WISCONSIN. LATEST 18Z RUC
INDICATED DECENT MOISTURE TRANSPORT AND CONVERGENCE ASSOCIATED WITH
SHORTWAVE TROUGH. THIS IS ALLOWING FOR A LINE OF SHOWERS AND
THUNDERSTORMS OVER EASTERN WISCONSIN PER LATEST MOSAIC
REFLECTIVITY. LATEST SURFACE ANALYSIS INDICATING FRONT EXTENDING
FROM NORTHEAST IOWA TO NORTHERN KANSAS. LATEST 18Z RUC INDICATING
GOOD SURFACE MOISTURE CONVERGENCE ALONG FRONT. LATEST MOSAIC RADAR
INDICATING A LINE OF SHOWERS AND THUNDERSTORMS EXTENDING FROM
SOUTHERN MINNESOTA INTO SOUTHEASTERN NEBRASKA.

THE 04.12Z GFS AND NAM ARE IN VERY GOOD AGREEMENT IN DEVELOPING
NORTHWEST FLOW ALOFT ACROSS THE UPPER MIDWEST AND GREAT LAKES
REGION BY 18Z TUESDAY. THE 04.12Z GFS...NAM AND 04.18Z RUC ARE
IN GOOD AGREEMENT IN MOVING SURFACE FRONT AND ASSOCIATED 850MB
MOISTURE TRANSPORT AND CONVERGENCE SOUTH AND EAST OF FORECAST AREA
BY 06Z TUESDAY. CONFIDENCE IS HIGH FOR BEST PRECIPITATION CHANCES
ACROSS SOUTHERN FORECAST AREA...AS THE SURFACE FRONT AND ASSOCIATED
LIFT MOVES ACROSS NORTHEAST IOWA AND SOUTHWEST WISCONSIN. MAIN
DIFFERENCE BETWEEN THE 04.12Z GFS AND NAM IS NAM MUCH STRONGER WITH
SHORTWAVE TROUGH EMBEDDED IN NORTHWEST FLOW ALOFT THURSDAY THAN GFS.
CONFIDENCE IN FORECAST FROM TUESDAY INTO THURSDAY IS MODERATE.

THIS EVENING AND TONIGHT...SURFACE FRONT AND ASSOCIATED LIFT AND
CONVERGENCE MOVES SOUTH AND EAST OF FORECAST AREA BY 06Z TUESDAY.
HAVE ADJUSTED BETTER PRECIPITATION CHANCES ACROSS SOUTHERN FORECAST
AREA. UPPER LEVEL SHORTWAVE TROUGH OVER THE DAKOTAS TRACKS EAST
ACROSS FORECAST AREA LATE TONIGHT. BOTH THE 04.12Z GFS AND NAM
INDICATE WEAK MOISTURE TRANSPORT AND CONVERGENCE AT 850MB WITH
SHORTWAVE TROUGH. WILL CONTINUE WITH SMALL CHANCES OF
PRECIPITATION ACROSS FORECAST AREA AFTER 06Z...AS LATEST MOSAIC
RADAR INDICATES SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS
ASSOCIATED WITH SHORTWAVE TROUGH.

SURFACE HIGH PRESSURE BUILDS INTO FORECAST AREA BY 00Z WEDNESDAY.
GOOD SUBSIDENCE UNDER SURFACE HIGH WILL SUPPRESS ANY MOISTURE AND
FORCING SOUTH AND EAST OF FORECAST AREA TUESDAY AFTERNOON AND
INTO WEDNESDAY. BOTH THE 04.12Z GFS AND NAM INDICATE DECENT
SUBSIDENCE OVER FORECAST AREA PER TIME HEIGHT CROSS SECTIONS. HAVE
REDUCED PRECIPITATION CHANCES AND TRENDED TOWARDS A FASTER DRIER
SOLUTION FOR TUESDAY.

NEXT SHORTWAVE TROUGH EMBEDDED IN NORTHWEST FLOW ALOFT AFFECTS
FORECAST AREA THURSDAY. THE 04.12Z NAM MUCH MORE AMPLIFIED WITH
SHORTWAVE TROUGH...HENCE BETTER MOISTURE AND LIFT ACROSS
NORTHERN PORTIONS OF FORECAST AREA THAN GFS. BOTH THE 04.12Z GFS AND
NAM DO INDICATE STEEP LAPSE RATES PER FORECAST SOUNDINGS. CONTINUED
PREVIOUS FORECAST TRENDS OF SMALL CHANCES ACROSS NORTHERN PARTS OF
FORECAST AREA.

.LONG TERM...THURSDAY NIGHT INTO MONDAY

MAIN FORECAST CONCERNS ARE TEMPERATURES THROUGH PERIOD. THE 04.00Z
GFS AND ECMWF ARE IN GOOD AGREEMENT WITH DIGGING UPPER LEVEL TROUGH
OVER THE NORTHEASTERN U.S. AND AMPLIFYING UPPER LEVEL RIDGE OVER THE
ROCKY MOUNTAINS THROUGH PERIOD. THIS WOULD ALLOW FOR NORTHERLY TO
NORTHWESTERLY FLOW OVER THE UPPER MIDWEST AND UPPER GREAT LAKES
REGION THROUGH THE PERIOD. BOTH THE MODELS DO INDICATE WEAK SHORTWAVE
TROUGHS EMBEDDED IN NORTHERLY/NORTHWESTERLY FLOW ALOFT TO MOVE
ACROSS THE UPPER MIDWEST AND GREAT LAKES REGION FRIDAY NIGHT INTO
SATURDAY. BOTH MODELS INDICATED TIMING DIFFERENCES WITH THE WEAK
SHORTWAVE TROUGHS. WITH WEAK LIFT...LIMITED MOISTURE AND
TIMING DIFFERENCES ASSOCIATED WITH SHORTWAVE TROUGHS WILL CONTINUE
WITH DRY FORECAST THROUGH PERIOD. THE 04.00Z GFS AND ECMWF ARE BOTH
IN AGREEMENT WITH COOLER AIR ADVECTING INTO FORECAST AREA BY 00Z
SATURDAY. BOTH MODELS INDICATING 850MB TEMPERATURES FROM PLUS 8
DEGREES CELSIUS TO PLUS 12 DEGREES CELSIUS ACROSS FORECAST AREA BY
00Z SUNDAY. THE 04.00Z GFS ENSEMBLES INDICATING SLIGHTLY COOLER
TEMPERATURES AT 850MB THAN THE OPERATIONAL MODELS. THOUGH...WILL
CONTINUE WITH BELOW NORMAL TEMPERATURES THROUGH PERIOD. CONFIDENCE
IN FORECAST THROUGH PERIOD IS MODERATE.

.AVIATION...LATE THIS AFTERNOON THROUGH TUESDAY MORNING

THE FRONTAL BOUNDARY RESPONSIBLE FOR THE SCATTERED SHRA/TS ACTIVITY
WILL BE SAGGING SLOWLY SOUTH OF THE AREA TONIGHT...BRINGING VFR
CONDITIONS INTO THE TAF SITES. MEANWHILE...AN UPPER LEVEL TROUGH OF
LOW PRESSURE OVER THE DAKOTAS WILL ROTATE SOUTHEAST INTO THE REGION
LATE THIS AFTERNOON AND TONIGHT. THIS MAY SPREAD A FEW MORE SHRA/TS
IN THE VICINITY OF THE KRST/KLSE TAF SITE THIS EVENING INTO THE
EARLY MORNING HOURS. NOT CONFIDENT THAT ANY ANY OF THESE SHRA/TS
WILL BE DIRECTLY AFFECTING THE TAF SITES...SO WILL KEEP A CB MENTION
IN FOR NOW ALONG WITH CONTINUED VFR CONDITIONS. A NORTHERLY AIRFLOW
ACROSS THE MOIST LOWER BOUNDARY LAYER PRODUCE A BROKEN DECK OF MVFR
STRATOCUMULUS IN THE 06-15Z TIME FRAME.

FLOODING...ESPECIALLY IN URBAN AREAS AND STEEP TERRAIN...WHERE
RAINFALL RUNOFF WILL BE ENHANCED.

.DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY

THE FRONT WILL CONTINUE TO PROVIDE A CHANCE OF THUNDERSTORMS ON
TUESDAY AS YET ANOTHER WAVE OF LOW PRESSURE MOVES ALONG IT. NONE
OF THESE THUNDERSTORMS ARE EXPECTED TO BECOME SEVERE.
