What was reported inside it

Time	Report	Where	Remark
Apr 7, 3:40 PM EDT	HAIL 1.75	Liberty, KY

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 tornado 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.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOUISVILLE KY
10 AM EDT FRI APR 7 2006

.MORNING UPDATE:
WILL LOWER POPS INTO CHC CAT INTO THE EARLY AFTN HOURS. ALSO WILL
GO WI PARTLY SUNNY SKIES AND UP MAX TEMPS TO AROUND 80 NORTH
TO THE LOWER 80S SOUTHWEST THIS AFTN.

REMAINDER OF FCST THE SAME

PREVIOUS FCST DISCUSSIONS BELOW:

.SHORT TERM (TODAY AND TONIGHT)...

AT 06Z SCATTERED THUNDERSTORMS WERE MOVING ACROSS THE NORTHEAST
PORTION OF THE FORECAST AREA JUST NORTH OF A WARM FRONT. THE
FRONT WAS LOCATED FROM EVV TO SDF TO JUST NORTH OF LEX AND MOVING
NORTH.

FAIRLY COMPLEX WEATHER SCENARIO FOR THIS FORECAST PERIOD. CLOSED
UPPER LOW OVER THE CENTRAL PLAINS THIS MORNING WILL OPEN AND DROP
SOUTHEAST AS A NORTHERN STREAM LOW ROTATES THROUGH THE NORTHEAST
STATES. A DEFORMATION ZONE WILL DEVELOP BETWEEN THIS NORTHERN AND
SOUTHERN STREAM IMPULSES JUST NORTH OF THE FORECAST AREA THIS
AFTERNOON. THE SURFACE LOW OVER NEBRASKA WILL DROP INTO SOUTHEAST
MISSOURI BY EVENING. THE FORE MENTIONED DEFORMATION ZONE SHOULD BE
THE FOCUS FOR THUNDERSTORM DEVELOPMENT LATE THIS AFTERNOON AS THE
ATMOSPHERE BECOMES UNSTABLE (LIS: MINUS 9 AND CAPES OF 1000 J/KG).
EXPECT A SQUALL LINE TO DEVELOP AND DROP SOUTH THROUGH THE FORECAST
AREA THIS EVENING. THE PRIMARY THREAT ALONG THE LINE WILL BE LARGE
HAIL BUT GUSTY WINDS WILL ALSO BE POSSIBLE.

COLD AIR ADVECTION WILL TAKE HOLD TONIGHT AS A COLD FRONT DROPS
SOUTH OF THE REGION BY 09Z.

WE SHOULD HAVE A BETTER HANDLE ON TEMPERATURES TODAY THAN YESTERDAY.
READINGS ARE ALREADY IN THE UPPER 60S ACROSS THE SOUTHWEST PORTION
OF THE CWFA. WE WILL MENTION UPPER 70S TO LOWER 80S TODAY WITH LOWS
EXPECTED TO BE SOME 30 DEGREES COOLER TONIGHT. --JA

.LONG TERM (SATURDAY THROUGH THURSDAY)...

SATURDAY AND SUNDAY...

SHOWERS WILL END FROM NORTH TO SOUTH DURING THE MORNING HOURS. A
SHARP COLD FRONT WILL BE LOCATED JUST SOUTH OF THE TENNESSEE BORDER
BY MID-MORNING SATURDAY. SHOWERS WILL LAG A FEW HOURS BEHIND THIS
FRONT AND ALL PRECIPITATION SHOULD EXIT THE STATE BY EARLY
AFTERNOON. CANADIAN HIGH PRESSURE WILL QUICKLY BUILD IN ACROSS THE
UPPER MIDWEST SATURDAY AND A NORTHERLY WIND WILL BRING IN MUCH
COOLER AND DRIER AIR DURING THE DAY. 925MB TEMPERATURES ARE FORECAST
TO FALL FROM 16C TO 1C FROM 18Z FRI TO 18Z SATURDAY.

SKIES WILL CLEAR AND WINDS WILL BECOME LIGHT BY EARLY SUNDAY AS HIGH
PRESSURE MOVES ACROSS ILLINOIS. BOTH THE GFS AND THE NAM ARE SIMILAR
IN FORECASTING LOWS FROM 30 TO 35 ACROSS ALL OF CENTRAL KENTUCKY AND
SOUTHERN INDIANA EARLY SUNDAY MORNING. IN ADDITION...WIDESPREAD
FROST WILL BE POSSIBLE AS WELL. PLANTS THAT ARE SENSITIVE TO COLD
TEMPERATURES MAY NEED TO BE PROTECTED. UNDER SUNNY SKIES AND LIGHT
WINDS...HIGHS ON SUNDAY WILL MODERATE FROM THOSE OF SATURDAY...BUT
STILL FALL A FEW DEGREES BELOW NORMAL FOR EARLY APRIL.

MONDAY THROUGH TUESDAY NIGHT...

A NICE SPRING PERIOD EXPECTED WITH AMPLE SUN AND WARMING
TEMPERATURES IS EXPECTED FOR THE EARLY PART OF THE WORK WEEK. AT THE
SURFACE...HIGH PRESSURE WILL MIGRATE EAST TOWARDS THE MID ATLANTIC
COAST BY TUESDAY. LIGHT WINDS WILL TURN SOUTHERLY BY TUESDAY...BUT A
RIDGE AXIS EXTENDING SOUTHWEST INTO THE NORTHERN GULF WILL INHIBIT
RAPID RETURN OF GULF MOISTURE. RIDGING ALOFT WILL DEVELOP ACROSS THE
LOWER OHIO VALLEY AS TROUGHING DEVELOPS ACROSS THE ROCKIES.
TEMPERATURES SHOULD APPROACH 70 BY MONDAY OR TUESDAY.

WEDNESDAY AND THURSDAY...

LOW PRESSURE MOVING WEST OF THE GREAT LAKES WEDNESDAY WILL ALLOW A
TROUGH TO MOVE EAST THROUGH OUR REGION WEDNESDAY. MODIFIED GULF AIR
WILL APPROACH FROM THE WEST AND SO WILL ADD LOW CHANCES FOR SHOWER
AND THUNDER WEDNESDAY. THIS SYSTEM IS WEAK HOWEVER...AND NO COLD AIR
WILL FOLLOW...AND SO WILL KEEP TEMPERATURES MILD THROUGH THURSDAY.
