The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.

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.

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 State College, PA wrote its last area forecast discussion before this severe thunderstorm warning went out at Jul 24, 1:57 PM EDT, 42 minutes earlier.

Area forecast discussion, Jul 24, 1:57 PM EDT, 42 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE STATE COLLEGE PA
157 PM EDT TUE JUL 24 2012

.SYNOPSIS...
A COLD FRONT WILL TRIGGER SCATTERED THUNDERSTORMS OVER SOUTHERN
PENNSYLVANIA THROUGH THE EVENING HOURS. MUCH DRIER AND LESS HUMID
AIR WILL ACCOMPANY HIGH PRESSURE INTO THE REGION OVERNIGHT AND
WEDNESDAY. UNSETTLED WEATHER WILL RETURN FOR THE SECOND HALF OF
THE WEEK.

&&

.NEAR TERM /THROUGH TONIGHT/...
SVR TSTM WATCH #510 IS IN EFFECT UNTL 00Z FOR THE SRN 1/3 OF THE
CWA. THE CONVECTIVE ENVIRONMENT IS CHARACTERIZED BY HIGH
INSTABILITY...RICH LLVL MSTR WITH DEWPOINTS IN THE UPPER 60S AND
LOW 70S AND FAVORABLE DEEP LYR SHEAR PROFILES WITH 40-50KT WNW
MID-LVL FLOW. EXPECT TSTMS TO CONTINUE TO DEVELOP THRU THE LATE
AFTN.

AFTN TEMPS IN THE LOW 90S WITH 70 DEWPOINTS WILL RESULT IN HX
VALUES CLOSE TO 100F OVR THE LWR SUSQ VLY.

THE SFC COLD FRONT WILL MOVE SWD LATE TONIGHT. ANY LINGERING
CONVECTION SHOULD SHIFT SOUTH OF THE MASON-DIXON LINE...AS MUCH
DRIER AND LESS HUMID AIR /BLW NORMAL PWATS/ OVERSPREADS THE CWA
FROM THE NORTH. OVERNIGHT READINGS WILL BE COMFORTABLE...MAINLY
IN THE 50S NORTH TO LOW 60S SOUTH. SOME USUALLY COLDER LOCATIONS
IN THE NRN MTNS COULD DIP INTO THE 40S.

&&

.SHORT TERM /WEDNESDAY THROUGH THURSDAY/...

THE DRY AIR WILL ALSO HEAT UP QUICKLY ON WEDNESDAY...WITH HIGHS
BOUNCING BACK TO NORMALS. WARM ADVECTION KICKS IN LATE IN THE DAY
OR OVERNIGHT INTO THURSDAY MORNING AS THE SFC HIGH OVERHEAD DIPS
SOUTHWARD AND A SFC LOW MOVES INTO LWR MICHIGAN. THE STRENGTH OF
THE LOW AND TIMING COULD LEAD TO AN MCS SLIDING W-E THROUGH THE
GREAT LAKES. VERY MINOR RIDGING ALOFT WILL CREST OVER THE AREA WED
NIGHT TOO...SO ANY NIGHTTIME CONVECTION MAY WELL SLIDE TO THE
NORTH OF THE STATE. HOWEVER...WE WILL BE FIRMLY ROOTED IN THE WARM
SECTOR FOR THE DAY ON THURSDAY. THUS...THE SLIGHT RISK SHOWS UP
FOR THURSDAY AGAIN. SFC LOW CROSSES NY STATE THROUGH THE DAY
THURS...BUT THE ASSOCD FRONT DOES NOT PUSH THROUGH ENTIRELY AS
THE FLOW IS ZONAL BY THEN. SO IT MAY STAY OVER THE NORTH OR WASH
OUT OVERHEAD.

TEMPS WILL SOAR ON THURSDAY...WITH AN EARLY/WARM START. NAM 8H
TEMPS IN THE M20S MID-DAY THURS. EC/GFS ARE COOLER WITH MUCH MORE
CLOUD DEBRIS OVER AT LEAST THE NRN HALF OF THE AREA. WILL GO WITH
THE WARMER SOLUTION SINCE THE AIR TO THE WEST HAS BEEN VERY HOT
LATELY. ONLY 2 OR 3 DAYS HAVE BEEN BELOW NORMAL SO FAR THIS
JULY...AND THEY WERE SOLIDLY RAINY DAYS. BUT WE LOOK TO BE BACK
INTO THE HEAT MOVING IN FROM THE WEST. WILL GO WITH THE PERSISTENT
WARM BIAS.

&&

.LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/...
HIGH CHANCES FOR SHRA/TSRA FRIDAY INTO SAT AS UPPER WAVE/COLD
FRONT SLIPS THROUGH. AHEAD OF THE COLD FRONT...TEMPS WELL ABOVE
NORMAL. SUNDAY LOOKS MAINLY DRY...BUT UNSETTLED WEATHER RETURNS BY
MON AS NW FLOW AGAIN SHARPENS TROUGH OVER GLAKES.

&&

.AVIATION /18Z TUESDAY THROUGH SUNDAY/...
SCT TSTMS WILL IMPACT SRN TERMINALS THIS AFTN AND USED VCTS FOR
NOW TO ACCOUNT FOR THIS. SFC COLD FRONT WILL PUSH SWD THIS EVE
WITH CONVECTION ENDING AFTER DARK. SOME 3-5SM VIS RESTRICTIONS ARE
POSSIBLE OVERNIGHT BUT CONFIDENCE IS LOW DUE TO ARRIVAL OF DRY AIR
AND LIGHT NW WINDS. VFR WILL PREVAIL ON WED UNDER HIGH PRES.

OUTLOOK...
WED...NO SIG WX EXPECTED.
THU-SAT...SCT TSRA IMPACTS POSSIBLE.

&&

.EQUIPMENT...
KCCX RADAR WILL BE OFFLINE UFN.

&&

.CTP WATCHES/WARNINGS/ADVISORIES...
NONE.
