The radar

The Goodland radar (KGLD), 109 km from the middle of the area, began a volume at 23:12 UTC, the scan nearest the moment this went out.

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.

The nearest sounding before it

Denver, CO (KDEN), launched 12:00Z, 11.1 hours before the alert went out and 173 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

NOT MANY ADJUSTMENTS NEEDED FROM PREVIOUS FORECAST THINKING WITH
PRIMARY NEAR/SHORT TERM METEOROLOGICAL CONCERNS BEING POPS AND
TEMPERATURES.

FORECAST DISTRICT CURRENTLY GRACED BY VARIABLE CLOUDS...ABOVE
SEASONAL LATER JULY TEMPERATURES(AS NOTED BY 101F TEMPERATURE AT
KPUB EARLIER THIS AFTERNOON)...GENERALLY LOW GRADE GRADIENT WINDS
AND DRY CONDITIONS...ALTHOUGH STRONG THUNDERSTORM ACTIVITY NOTED AT
TIMES TO THE NORTH IN WRAY COUNTY COLORADO AND CONVECTION IS
ATTEMPTING TO DEVELOP AT TIMES OVER SECTIONS OF
KIOWA...BENT...PROWERS AND BACA COUNTIES.

A 594 DECAMETER UPPER HIGH CENTERED NEAR LUBBOCK TEXAS THIS
AFTERNOON IS PROJECTED TO SHIFT TO NEAR AMARILLO TEXAS BY FRIDAY
AFTERNOON.  IN ADDITION...NEXT NORTHERLY SURFACE SURGE IS PROJECTED
TO PUSH INTO THE AREA BY FRIDAY MORNING WITH SURFACE BOUNDARY
EXPECTED TO BE LOCATED OVER SOUTHEASTERN COLORADO BY FRIDAY
AFTERNOON.  ALSO...MOISTURE PLUME MOVES ACROSS PORTIONS OF THE

THE COMBINATION OF THE RECENTLY MENTIONED FACTORS AS WELL AS THE
DIURNAL HEATING CYCLE WILL ALLOW FOR GENERALLY ISOLATED PRIMARILY
AFTERNOON AND EVENING SHOWERS AND THUNDERSTORMS IN COMBINATION WITH
ABOVE SEASONAL TEMPERATURES OVER THE MAJORITY OF FORECAST DISTRICT
TONIGHT AND FRIDAY.

ISSUED AT 303 PM MDT THU JUL 23 2015

UPPER HIGH PRESSURE WILL GENERALLY REMAIN CENTERED OVER TEXAS AND
OKLAHOMA SATURDAY THROUGH WEDNESDAY...AND THEN RETROGRADE AND
AMPLIFY OVER THE GREAT BASIN ON THURSDAY. THIS WILL KEEP SOUTHERN
COLORADO UNDER A MODERATE MONSOON FLOW THROUGH WEDNESDAY.
THEN...ON THURSDAY...IF MODEL FORECASTS ARE CORRECT...A DRIER
NORTHWEST FLOW WOULD OVERSPREAD THE REGION. PRIMARY THUNDERSTORM
THREATS THROUGH THE PERIOD WILL BE LIGHTNING...WIND GUSTS TO
AROUND 50 MPH...LOCALLY HEAVY RAIN AND SMALL HAIL.  HOWEVER...AT
TIMES...LIFT...CAPE...INSTABILITY...BOUNDARY FEATURES SUCH AS THE
DRY LINE...AND WIND SHEAR WILL COME TOGETHER TO PRODUCE SOME
SEVERE STORMS. IN THESE CASES...WIND GUSTS IN EXCESS OF 60
MPH...RAINFALL RATES CAPABLE OF FLASH FLOODING...AND HAIL AN INCH
OR MORE IN DIAMETER WILL BE POSSIBLE. ALL IN ALL...A PRETTY
TYPICAL LATE JULY WEATHER SCENARIO FOR SOUTHERN COLORADO.

&&
