What happened

The episode as NWS PAH wrote it up.

Strong south winds occurred between a low pressure center over Kansas and high pressure off the southeast United States coast. Peak wind gusts ranged from 40 to 45 mph generally along and west of Interstate 57, which runs from Mount Vernon south to Cairo. In northern Williamson County, the metal roof of a lumber company in Johnston City collapsed. The metal roof was over a building that was of a pole-barn type of construction. The east side wall nearly came down. The roof was new, installed to replace the one blown off in the May 8 windstorm of 2009. Some power lines were blown down in the area.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PADUCAH KY
330 AM CDT TUE APR 6 2010

.DISCUSSION...
PRIMARY FORECAST CONCERNS OVER THE NEXT FEW DAYS INCLUDE...
(1) WINDS AND DEW POINTS TODAY
(2) CHANCE OF PRECIPITATION LATE TONIGHT THROUGH EARLY THURSDAY
(3) HEAVY RAIN POTENTIAL WEDNESDAY NIGHT
(4) FROST POTENTIAL THURSDAY NIGHT

ANOTHER WINDY DAY IS SHAPING UP ACROSS THE FORECAST AREA AS THE
PRESSURE GRADIENT TIGHTENS BETWEEN HIGH PRESSURE TO OUR EAST AND LOW
PRESSURE DEVELOPING OVER THE PLAINS. BUFKIT NAM/GFS FORECAST
SOUNDINGS INDICATE WINDS AS HIGH AS 40 KNOTS AT THE TOP OF THE
MIXED LAYER...JUST BELOW THE INVERSION THIS AFTERNOON...AT BOTH THE
SALEM IL AND EVANSVILLE IN FORECAST POINTS. THIS WOULD RESULT IN
CONDITIONS APPROACHING ADVISORY CRITERIA...ESPECIALLY ACROSS
SOUTHWEST INDIANA...SOUTHERN ILLINOIS...AND NORTHERN PORTIONS OF
SOUTHEAST MISSOURI. HOWEVER...FORECAST SUSTAINED WINDS OF 20 TO 25
KNOTS AND GUSTS OF 30 TO 35 KNOTS DO FALL JUST SHORT OF CRITERIA...
SO WILL INSTEAD HIGHLIGHT IN THE HWO AND SPS PRODUCTS. ALSO...WINDS
AND FUEL MOISTURE VALUES WILL BOTH CONTRIBUTE TO AN INCREASED FIRE
DANGER TODAY...THOUGH RELATIVE HUMIDITY VALUES WILL FALL SHORT OF
RED FLAG WARNING CRITERIA.

THE AFOREMENTIONED LOW OVER THE PLAINS WILL BEGIN TO PUSH EAST
TOWARDS THE GREAT LAKES REGION TONIGHT...DRAGGING A COLD FRONT INTO
THE QUAD STATE REGION ON WEDNESDAY. EARLY ON...PRECIPITATION WILL
LIKELY BE HIT AND MISS AS IT BEGINS TO IMPACT SOUTHEAST MISSOURI AND
SOUTHWEST ILLINOIS LATE TONIGHT AND WEDNESDAY MORNING. HOWEVER...AS
THE UPPER LEVEL SUPPORT KICKS IN WEDNESDAY AFTERNOON AND ESPECIALLY
INTO WEDNESDAY NIGHT...PRECIPITATION COVERAGE SHOULD BECOME MUCH
BETTER.

INSTABILITY PARAMETERS WILL SUPPORT THUNDERSTORMS DURING THIS
TIME...AND SPC DOES HAVE THE AREA HIGHLIGHTED IN A DAY 2 SLIGHT
RISK. HOWEVER...THE GREATER FOCUS MAY ACTUALLY TURN OUT TO BE
LOCALLY HEAVY RAIN...GIVEN HPC/S DAY 2 QPF FORECAST OF 1 TO 2+
INCHES...MAINLY OVER SOUTHWEST INDIANA AND WESTERN KENTUCKY.

PRECIPITATION WILL SHIFT EAST OF THE REGION EARLY THURSDAY...BUT
CLOUDS WILL BE SLOW TO CLEAR. DEPENDING UPON HOW QUICKLY SKIES CLEAR
THURSDAY AND THURSDAY NIGHT...FROST FORMATION COULD BECOME ANOTHER
ISSUE AS TEMPERATURES ARE FORECAST TO FALL INTO THE 30S OVER MUCH OF
THE AREA THURSDAY NIGHT. WILL NEED TO TAKE A CLOSER LOOK AT THIS AS
THE TIME PERIOD IN QUESTION DRAWS NEAR.

LATE IN THE WEEK AND INTO NEXT WEEKEND...A DRY PLEASANT PERIOD IS
SHAPING UP UNDER THE DOMINANCE OF HIGH PRESSURE. TEMPERATURES WILL
ACTUALLY BE SEVERAL DEGREES BELOW NORMAL LATE IN THE WEEK...BUT
SHOULD MODERATE BACK TO SEASONAL NORMS BY EARLY NEXT WEEK.

&&

.AVIATION...
GUSTY WINDS WILL BE THE MAIN CONCERN THIS ISSUANCE. GUSTS WILL KICK
IN RAPIDLY AFTER SUNRISE AT ALL SITES AS WEAK INVERSION WILL RAPIDLY
ERODE. WE WILL APPROACH BUT SHOULD NOT EXCEED ADVISORY CRITERIA.
OTHERWISE CIGS AND VSBY WILL BE VFR.

TODAY...

SOUTH TO SOUTHWEST WINDS 15 TO 25 MPH...WITH LOCAL WIND GUSTS 35

THOSE PERSONS DRIVING TRACTOR TRAILERS AND RECREATIONAL VEHICLES

WATERCRAFT.

LOOSE OUTDOOR OBJECTS WILL BE TOSSED AROUND AND SOME BROKEN TREE
LIMBS MAY TOPPLE AND FALL.

AN ELEVATED FIRE DANGER WILL EXIST AS WELL THIS AFTERNOON...DUE TO
THE STRONG WINDS AND DRYING OF SHORT DURATION FUEL SOURCES.
