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

Area forecast discussion, Oct 13, 2:32 PM MDT, 4 hours 27 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GOODLAND KS
232 PM MDT MON OCT 13 2003

.DISCUSSION...
THE 19Z SURFACE ANALYSIS PLACES A TROUGH FROM NORTHEAST KANSAS INTO
THE TEXAS PANHANDLE WITH HIGH PRESSURE RIDGING INTO NORTHEAST
COLORADO. THE LATEST RADAR INDICATES LINE OF SHOWERS AND SPRINKLES
EXTENDING FROM GLD TO MCK. THE UPPER TROUGH AXIS IS ALONG THE
KANSAS/COLORADO BORDER.

MAIN QUESTION FOR TONIGHT IS WHETHER POPS WILL BE NEEDED FOR VERY
LIGHT PRECIPITATION ASSOCIATED WITH JET MOVING NORTHEAST ACROSS THE
AREA. LATEST RADAR TRENDS/SATELLITE/MESOETA INDICATE THAT TROUGH/RW-
SHOULD STILL LINGER OVER THE EASTERN FORECAST EVEN THOUGH IT IS FAST
MOVING. LINE OF SHOWERS SHOULD EXTEND FROM EAST OF CBK TO HLC AT 00Z
AND MOVE OUT OF THE FORECAST AREA BY 03Z.  ALSO...LOW TEMPERATURES
WILL ALSO BE A CONCERN TONIGHT. HOWEVER...THE ETA/RUC BOTH INDICATE
THAT NORTHWEST WIND WILL RANGE BETWEEN 5 TO 10 KNOTS THROUGHOUT THE
NIGHT. THIS SHOULD PROVIDE DECENT MIXING AND KEEP TEMPERATURES ABOVE
FREEZING IN MOST PLACES EXCEPT COLORADO ZONES. ISOLATED TO SCATTERED
FROST MAY BE A POSSIBLILITY THERE. HIGH PRESSURE/SUBSIDENCE WILL
DOMINATE ON TUESDAY WITH LIGHT NORTHWEST WIND. A LEE TROUGH DEVELOPS
TUESDAY NIGHT WITH RESULTING SOUTHWEST WIND MODERATING LOW
TEMPERATURES. THERE IS SOME WEAK ENERGY MOVING ACROSS THE NORTHERN
U.S. BUT ITS SOUTHERN EDGE IS TOO FAR AWAY TO AFFECT THE FORECAST
AREA. ANOTHER WIND SHIFT BEHIND THE LEE TROUGH PASSAGE WILL BRING
NORTHWEST WIND ON WEDNESDAY. HIGH PRESSURE FOLLOWS WITH LIGHT EAST
WIND WEDNESDAY NIGHT. AN UPPER TROUGH MOVES THROUGH ON THURSDAY WITH
SHORTWAVE ENERGY PROVIDING SOME UPWARD VERTICAL VELOCITIES OVER THE
FORECAST AREA. HOWEVER...LOW LEVEL MOISTURE IS SCARCE AND MID LEVEL
IS NOT A WHOLE LOT BETTER. THIS EVENT COULD BE ANOTHER ISOLATED
SPRINKLE EVENT WITH MAINLY MID CLOUD AROUND. FOR NOW...WILL LEAVE
FORECAST DRY. HIGH PRESSURE BUILDS BACK INTO THE AREA THURSDAY NIGHT
AS THE UPPER TROUGH SHIFTS EAST. 850 TEMPERATURES INDICATE
TEMPERATURES WILL BE ABOUT THE SAME FOR TUESDAY AS TODAY AND WARM A
FEW DEGREES WEDNESDAY/THURSDAY.

DAYS 4-7...DRY WEATHER PERSISTS WITH THE RIDGE ANCHORED OVER THE
ROCKIES. AT THE SURFACE HIGH PRESSURE ALTERNATES WITH LEE TROUGHS
AND WIND SHIFTS FROM THE NORTHWEST. MOISTURE/DYNAMICS LIMITED SO NIL
POPS THOUGH THIS FORECAST. 850 TEMPERATURES WARM INTO THE LOWER 20S
SO BY MONDAY...MAX TEMPERATURES SHOULD GET INTO THE LOWER 80S AHEAD
OF LEE TROUGH.
