What was reported inside it

Time	Report	Where	Remark
Apr 7, 3:26 PM CDT	HAIL 0.25	Hayfield, MN	HAS LASTED ABOUT 10 MINUTES

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

Minneapolis, MN (KMPX), launched 12:00Z, 8.3 hours before the alert went out and 124 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.

Area forecast discussion, Apr 7, 2:50 PM CDT, 25 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LA CROSSE WI
250 PM CDT TUE APR 7 2015

.SHORT TERM...(TONIGHT THROUGH WEDNESDAY NIGHT)
ISSUED AT 250 PM CDT TUE APR 7 2015

WATER VAPOR SATELLITE IMAGERY SHOWS A FAIRLY VIGOROUS MID-LEVEL
TROUGH PUSHING OUT OF THE CENTRAL/NORTHERN PLAINS TOWARD THE UPPER
MISSISSIPPI RIVER VALLEY. FAIRLY STRONG PUSH OF MOISTURE TRANSPORT
AND ELEVATED/2-5KM MUCAPE AHEAD OF THE WAVE WAS FUELING SCATTERED
SHOWERS AND THUNDERSTORMS ACROSS CENTRAL AND SOUTHERN MN AND
PORTIONS OF IA. OTHERWISE...A PRETTY RAW DAY ACROSS THE AREA WITH
BRISK EASTERLY SURFACE FLOW AND AMPLE CLOUD COVER KEEPING
TEMPERATURES IN THE UPPER 30S THE LOWER 40S.

WILL SEE SHOWERS AND SCATTERED THUNDERSTORMS CONTINUE PUSHING
THROUGH THE AREA THIS EVENING...THEN TAPER OFF FROM WEST TO EAST
AFTER MIDNIGHT AS THE MID-LEVEL TROUGH EXITS EAST. NOT ANTICIPATING
ANYTHING SEVERE...BUT A FEW OF THE STRONGER STORMS GOING INTO THIS
EVENING MAY CONTAIN SOME SMALL HAIL. OTHERWISE...EASTERLY SURFACE
FLOW CONTINUES TONIGHT WITH TEMPERATURES FALLING INTO THE 33-40
DEGREE RANGE.

WEDNESDAY LOOKS DRY THROUGH LATE AFTERNOON BEFORE SHOWER CHANCES
START TO SPREAD INTO NORTHEAST IA/SOUTHEAST MN. THIS IS IN RESPONSE
TO INCREASING MOISTURE TRANSPORT AHEAD OF A STRONG WAVE OF LOW
PRESSURE MOVING OUT OF THE SOUTHERN PLAINS. ANOTHER COOLER THAN
NORMAL DAY OTHERWISE AS EAST WINDS OF 10-20 MPH CONTINUE WITH THICK
CLOUD COVER. LOOK FOR HIGHS RANGING FROM THE MIDDLE 40S ACROSS
CENTRAL WI...TO THE LOWER 50S ALONG AND WEST OF THE MISSISSIPPI
RIVER.

SHOWERS AND THUNDERSTORMS  OVERSPREAD THE AREA WEDNESDAY NIGHT AS
LOW PRESSURE DEEPENS/LIFTS NORTHEAST OUT OF THE SOUTHERN PLAINS INTO
IOWA. MODELS SHOWING FAIRLY STRONG 850MB MOISTURE TRANSPORT AHEAD OF
THE LOW WITH NAM DEPICTING 1-5KM/ELEVATED MUCAPE RANGING FROM NEAR
300J/KG ALONG AND NORTH OF I-94...AND 500-1000J/KG SOUTH OF I-90.
THIS IS EXPECTED TO PRODUCE SHOWERS AND SCATTERED THUNDERSTORMS
THROUGH THE NIGHT WITH A FEW OF THE STRONGER STORMS CAPABLE OF SOME
SMALL HAIL. LOWS WEDNESDAY NIGHT WILL RANGE FROM 35 TO 45 DEGREES.

.LONG TERM...(THURSDAY THROUGH TUESDAY)
ISSUED AT 250 PM CDT TUE APR 7 2015

MODEL CONSENSUS BRINGS THE SURFACE LOW INTO SOUTHERN WI BY THURSDAY
AFTERNOON KEEPING THE MAJORITY OF THE AREA ON THE COOL/NORTHWEST
SIDE OF THE LOW. PORTIONS OF NORTHEAST IOWA AND FAR SOUTHWEST WI
COULD GET INTO THE WARM SECTOR. GFS PUSHES 0-3KM MUCAPE INTO THE
1500-3000J/KG RANGE ACROSS THIS AREA WITH 0-3KM BULK SHEAR IN THE 25-
35KT RANGE. OTHERWISE...PRECIPITABLE WATER VALUES CREEP ABOVE 1 INCH
FOR SOME HEAVIER RAINFALL POTENTIAL AS WELL.  AS SUCH...WILL HAVE TO
MAINTAIN VIGILANT EYE FOR SEVERE THUNDERSTORM/HEAVY RAINFALL
POTENTIAL. PLAN ON HIGHS IN THE UPPER 40S ACROSS NORTHERN WI...TO
THE MIDDLE 60S ACROSS PORTIONS OF NORTHEAST IA INTO FAR SOUTHWEST
WI.

AS THE LOW PULLS NORTHEAST OF THE AREA THURSDAY NIGHT...ENOUGH COLD
AIR FILTERS IN FOR THE POTENTIAL OF RAIN MIXING WITH/CHANGING TO
SNOW. THIS LOOKS TO BE MOST LIKELY ACROSS NORTH CENTRAL WI WHERE A
TRACE TO AN INCH COULD OCCUR AS LOWS DROP INTO THE LOWER/MIDDLE 30S.

A FEW SPRINKLES WILL STILL BE POSSIBLE ON FRIDAY WITH LINGERING
COOL/CYCLONIC FLOW ALOFT AND FAIRLY STEEP LOW LEVEL LAPSE RATES.
HIGHS ON FRIDAY LOOK TO BE IN THE UPPER 40S TO THE MIDDLE 50S.

WARMER TEMPERATURES ON TAP FOR THE WEEKEND AS WARM AIR ADVECTION
TAKES PLACE AHEAD OF A COLD FRONT PUSHING THROUGH THE NORTHERN
PLAINS. HOWEVER...THERE WILL ALSO BE AN INCREASING CHANCE OF SHOWERS
AND THUNDERSTORMS WITH THE APPROACH OF THE COLD FRONT. LOOK FOR
HIGHS SATURDAY IN THE MIDDLE 50S TO THE MIDDLE 60S AND 60S/NEAR 70
ON SUNDAY.

SHOWERS AND THUNDERSTORMS BECOMING LIKELY SUNDAY NIGHT INTO MONDAY
WITH THE PASSAGE OF THE COLD FRONT. LINGERING SHOWERS STILL POSSIBLE
ON TUESDAY MAINLY EAST OF THE MISSISSIPPI RIVER. OTHERWISE...PLAN ON
HIGHS MONDAY AND TUESDAY IN THE UPPER 50S/LOWER 60S.

&&

.AVIATION...(FOR THE 18Z TAFS THROUGH 18Z WEDNESDAY AFTERNOON)
ISSUED AT 1230 PM CDT TUE APR 7 2015

MVFR/IFR CIGS TO PREVAIL THIS PERIOD AS THE AREA IS CAUGHT IN MOIST
EASTERLY FLOW NORTH OF A WARM FRONT AND A LOW PASSING ACROSS
NORTHERN MO/IL. INCREASING LIFT/MOISTURE AHEAD OF THE LOW WILL SEND
A ROUND OF SHRA/TSRA ACROSS THE TAF SITES...MAINLY LATE THIS
AFTERNOON AND THIS EVENING. CONFIDENCE IS NOT THE HIGHEST...BUT
ENOUGH LIFT AND SOME WEAK INSTABILITY...DID ADD A TEMPO PERIOD OF
TSRA/CB FOR 2-3HRS WHEN THE STRONGER OF THE LIFT WOULD BE PASSING
ACROSS THE TAF SITES. MVFR VSBYS IN SHRA/BR LATE THIS AFTERNOON/
EVENING WITH SOME IFR CIGS/VSBYS IN ANY TSRA...ESPECIALLY AT HIGHER
TERRAIN SITES LIKE KRST. IFR/LIFR CIGS AND MVFR/IFR VSBYS EXPECTED
FROM LATE EVENING INTO EARLY WED MORNING WITH WEAKER GRADIENT WINDS
AND BOUNDARY LAYER MOISTENING FROM THE LATE AFTERNOON/EVENING
SHRA/TSRA. WEAK RIDGE OF HIGH PRESSURE WITH SOME DRIER LOW LEVEL AIR
LOOKS TO NOSE IN FOR LATER WED MORNING/AFTERNOON WITH SOME
DISSIPATION OF THE BR AND CIGS RISING TO MVFR/IFR.
