What forecasters said that day

The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Wilmington, OH wrote its last area forecast discussion before this severe thunderstorm warning went out at Jul 19, 8:01 PM EDT, 1 hour 44 minutes earlier.

Area forecast discussion, Jul 19, 8:01 PM EDT, 1 hour 44 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WILMINGTON OH
801 PM EDT THU JUL 19 2012

.SYNOPSIS...
A COLD FRONTAL BOUNDARY AND AN ASSOCIATED WAVE OF LOW PRESSURE
WILL APPROACH AND MOVE THROUGH THE AREA TONIGHT INTO FRIDAY. HIGH
PRESSURE WILL THEN MOVE INTO THE AREA FOR THE WEEKEND.

&&

.NEAR TERM /UNTIL 6 AM FRIDAY MORNING/...
UPDATED THE FORECAST TO CANCEL THE EXCESSIVE HEAT WARNING AND HEAT
ADVISORY. CLOUD COVER ACROSS THE AREA WILL KEEP TEMPERATURES BELOW
CRITERIA THIS EVENING. MADE ONLY MINOR ADJUSTMENTS TO TEMPERATURES
FOR THE OVERNIGHT TIME FRAME TO ADJUST FOR CURRENT TRENDS.

THUNDERSTORMS OVER INDIANA WILL CONTINUE TO MOVE TOWARD THE FA
THIS EVENING. WITH CLOUD COVER AND THE LOSS OF DAYTIME
HEATING...THERE IS SOME QUESTION ON HOW FAR THE SEVERE THREAT WILL
EXTEND INTO THE FA. WESTERN PORTIONS WILL HAVE THE GREATEST THREAT
FOR SEEING SOME SEVERE WEATHER THIS EVENING WITH THE MAIN THREATS
BEING WIND AND HAIL. IN ADDITION...LOCALLY HEAVY RAINFALL WILL BE
POSSIBLE WITH SOME OF THESE THUNDERSTORMS. CONTINUED THE SEVERE
AND HEAVY RAIN WORDING IN THE GRIDS AND THE HWO.

&&

.SHORT TERM /6 AM FRIDAY MORNING THROUGH FRIDAY NIGHT/...
FRONTAL BOUNDARY WILL CONTINUE TO WORK THROUGH THE FA ON FRIDAY.
PRECIPITATION WILL TAPER OFF ACROSS THE FA FROM NW TO SE DURING
THE DAY. TEMPERATURES WILL BE COOLER FOR FRIDAY WITH PRECIPITATION
AND FRONTAL BOUNDARY. HIGH TEMPERATURES WILL BE IN THE LOW TO
MIDDLE 80S FOR FRIDAY. CLOUD COVER WILL DECREASE FRIDAY NIGHT AND
WITH COOLER AIR WORKING INTO THE AREA TEMPERATURES WILL DROP DOWN
INTO THE LOW TO MIDDLE 60S.

&&

.LONG TERM /SATURDAY THROUGH THURSDAY/...
MODEL AGREEMENT FOR THE EXTENDED PERIOD REMAINS IN FAIR SHAPE...IN
TERMS OF THE LARGE SCALE FEATURES. GFS ENSEMBLE MEANS CONTINUE TO
SHOW A RELATIVELY SMALL AMOUNT OF SPREAD THROUGH AT LEAST TUESDAY.
THE OVERALL PATTERN WILL BEGIN WITH THE CONTINUED DOMINANCE OF A
CENTRAL US RIDGE...WHICH LOSES SOME OF ITS INFLUENCE OVER THE
EASTERN US AS A TROUGH MOVES INTO THE NORTHEAST LATE IN THE EXTENDED
PERIOD.

HEIGHTS WILL BE RISING BY SATURDAY...AS THE RIDGE BUILDS ITS
INFLUENCE INTO THE OHIO VALLEY AND SHUNTS A TROUGH OFF TO THE EAST
AS IT DE-AMPLIFIES. WEAK SURFACE HIGH PRESSURE WILL ALSO DEVELOP AT
THIS TIME. ALTHOUGH THE RECENT RAINFALL MAY HAVE TEMPERED THE
EXTREMELY DRY CONDITIONS TO SOME SMALL DEGREE...IT IS STILL EXPECTED
THAT THE MODEL TEMPERATURES COULD BE TOO CONSERVATIVE ON
TEMPERATURES. TEMPS ON SATURDAY ARE CLOSE TO MET/NAM NUMBERS AND
THEN ABOVE MAV NUMBERS THROUGH EARLY IN THE WEEK. THIS WILL BRING A
RETURN OF 90 DEGREE TEMPERATURES ON MONDAY (AND PERHAPS ALSO IN THE
CINCINNATI METRO ON SUNDAY).

BEYOND MONDAY...THE RIDGE WILL FLATTEN SLIGHTLY...ALLOWING THE CWA
TO ENTER A NORTHWEST FLOW REGIME WITH OCCASIONAL DISTURBANCES MOVING
FROM THE NORTHERN MISSISSIPPI VALLEY THROUGH THE MID-ATLANTIC
STATES. WHILE THESE FEATURES WILL ALMOST CERTAINLY BRING SOME
PERIODS OF CONVECTION TO THE REGION...THESE INDIVIDUAL DETAILS ARE
DIFFICULT TO PICK OUT CORRECTLY THIS FAR IN ADVANCE. SO...SLIGHT
CHANCE POPS WILL BE USED FOR TUESDAY THROUGH THURSDAY...WITH JUST A
SLIGHT REDUCTION IN TEMPERATURES EACH DAY.

&&

.AVIATION /00Z FRIDAY THROUGH TUESDAY/...
A LINE OF STORMS IS PROGGED TO GET TO THE TAF SITES TO BETWEEN 2
AND 4Z THIS EVENING. BEHIND THE CONVECTION THERE SHOULD BE SOME
LOWERING CIGS WITH THE INCREASED MOISTURE IN THE LOW LEVELS AND
COLD AIR BEING PULLED IN THE POST-FRONTAL ATMOSPHERE LATER
OVERNIGHT. HAVE SOME MVFR VSBYS AND TEMPO CIGS AOA 1KFT DURING THE
PREDAWN HOURS. ANY LOW CIGS WILL LIFT INTO A STRATUS OR BKN
STRATOCU DECK EARLY IN THE DAY AND MIX OUT BY LATE MORNING/EARLY
AFTERNOON.

ANY PRECIPITATION AFTER 6Z TONIGHT WILL LIKELY BE STRATIFORM
SHOWERS IN THE WAKE AND COLD POOL THAT IS LAID DOWN BY EARLIER
CONVECTION. AM STILL UNSURE THAT THIS IS THE WAY IT IS GOING TO
DEVELOP SO I AM JUST KEEPING THE VSBY RESTRICTIONS WITH LOWER
CIGS.

OUTLOOK...THUNDERSTORMS POSSIBLE TUESDAY.
