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.

200 PM MDT SUN AUG 28 2011

AN UPPER LEVEL DISTURBANCE CURRENTLY PRODUCING SHOWERS AND
THUNDERSTORMS ALONG AND WEST OF THE CONTINENTAL DIVIDE WILL MOVE
INTO THE TRI-STATE AREA TONIGHT BRINGING A GOOD CHANCE OF
PRECIPITATION TO AREAS GENERALLY ALONG AND NORTH OF THE
INTERSTATE. ANOTHER DISTURBANCE MOVES THROUGH DURING THE AFTERNOON
AND EARLY EVENING WITH DRIER AIR MOVING IN FROM NORTHWEST TO
SOUTHEAST MONDAY NIGHT. PRECIPITABLE WATER VALUES ARE RATHER HIGH
AND 0-6KM WINDS ARE VERY LIGHT...LOCALLY HEAVY RAINFALL IS
POSSIBLE. WITH THE EXPECTED CLOUD COVER/COOLER 850 TEMPERATURES
AND EAST TO NORTHEAST WINDS MONDAYS HIGH TEMPERATURES SHOULD
RETURN BACK AND/OR SLIGHTLY BELOW NORMAL WITH READINGS IN THE LOW
TO MID 80S...MAY SEE 90 TOWARD TRIBUNE WHERE CLOUDS MAY BE LESS
THEN FURTHER NORTH. IF THE CLOUDS ARE THICKER THEN CURRENTLY
EXPECTED CURRENT ADVERTISED NUMBERS MAY BE ABOUT 3F TOO WARM.

FOR TUESDAY THROUGH THURSDAY UPPER HIGH SLIDES INTO THE SOUTHERN
PLAINS AND UPPER FLOW SLOWLY BACKS TO THE SOUTHWEST AS AN UPPER
TROUGH MOVES INTO THE PACIFIC NORTHWEST. ALTHOUGH ISOLATED
AFTERNOON/EARLY EVENING THUNDERSTORMS ARE POSSIBLE THE BIGGER
WEATHER STORY WILL BE THE HEAT. AFTERNOON HIGHS WILL BE WELL INTO
THE 90S WITH A FEW 100S POSSIBLE...MAINLY ON WEDNESDAY AND MORE
PROBABLE ON THURSDAY.

FRIDAY-SUNDAY...UPPER FLOW SHIFTS TO THE NORTHWEST ALLOWING COOLER
AIR TO MOVE INTO THE AREA. HIGHS IN THE 80S GENERALLY EXPECTED
WITH OVERNIGHT LOWS IN THE 50S AND 60S.

FOR THE 18Z TAF...PRIMARY AVIATION CONCERN WILL BE WHAT...IF
ANY...IMPACTS CONVECTION WILL HAVE FOR KGLD AND KMCK THIS
AFTERNOON AND EVENING. APPEARS LIKELY THERE WILL BE CONVECTION
ACROSS THE TRI-STATE REGION BUT EXACT TIMING AND COVERAGE REMAINS
UNCERTAIN. WILL CONTINUE TO MENTION VCTS FOR THE MOST LIKELY
IMPACT TIMES. A COLD FRONT WILL MOVE THROUGH THE TERMINALS
OVERNIGHT WITH WINDS BECOMING NORTHERLY/NORTHEASTERLY AND GUSTING
TO NEAR 20 MPH BEHIND THE FRONT. GUIDANCE HINTING AT POTENTIAL FOR
LOW STRATUS DEVELOPING NEAR KMCK AROUND 11Z TOMORROW SO THIS WILL
