Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this flash flood 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 GOODLAND KS
115 AM MDT SAT JUL 10 2004

.DISCUSSION...UPPER RIDGE WILL REMAIN IN PLACE ACROSS THE
CENTRAL/SOUTHERN PLAINS THROUGH THE FORECAST PERIODS. THE PRIMARY
CONCERNS FOR THIS FORECAST PACKAGE WILL BE LINGERING MORNING
SHOWERS/THUNDERSTORMS AND ISOLATED THUNDERSTORM DEVELOPMENT BY LATE
AFTERNOON AND EVENING. AFTER TODAY THE MAIN CONCERN THROUGH THE
REMAINDER OF THE SHORT TERM PERIODS WILL BE HOW HIGH TEMPERATURES
WILL CLIMB AS 700 MB TEMPERATURES WARM INTO THE MID/UPPER TEENS WITH
VERY DRY MID LEVEL AIR UNDER 594 RIDGE.

ABUNDANT MID LEVEL MOISTURE WILL REMAIN IN PLACE TODAY AND ISOLATED
THUNDERSTORMS MAY DEVELOP ALONG ANY REMAINING BOUNDARY ACROSS THE
FORECAST AREA. THE BEST MOISTURE/INSTABILITY WILL REMAIN IN THE
EAST. SOUTH TO SOUTHWEST FLOW AND VERY WARM 850 TEMPERATURES SHOULD
ALLOW TEMPERATURES TO CLIMB INTO THE MID 90S. EXPECT A GRADUAL
WARMING TREND THROUGH THE REMAINDER OF THE SHORT TERM PERIODS WITH
UPPER 90S/AROUND 100 POSSIBLE SUNDAY AND MONDAY. STILL DIFFICULT TO
RULE OUT AN ISOLATED LATE AFTERNOON/EVENING THUNDERSTORM AND KEPT A
SLIGHT CHANCE MENTION SUNDAY EVENING AS A WEAK SHORT WAVE RIDES OVER
THE RIDGE.

DAYS 4 THROUGH 7...NO CHANGES.
