The radar

The Goodland radar (KGLD), 108 km from the middle of the area, began a volume at 03:15 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 00:00Z, 3.3 hours before the alert went out and 38 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.

Area forecast discussion, Jun 23, 8:54 PM MDT, 21 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DENVER/BOULDER CO
854 PM MDT TUE JUN 23 2015

.UPDATE...
ISSUED AT 836 PM MDT TUE JUN 23 2015

ISOLATED TO SCATTERED COVERAGE OF STORMS ON THE PLAINS THIS
EVENING CONTINUES...BUT WITH DECREASING INTENSITY OF STORMS.
MOUNTAINS AND FRONT RANGE STORMS HAVE ENDED FOR THE EVENING AND
LINGERING SHOWERS ON THE PLAINS EXPECTED TO BE DONE BY MIDNIGHT.
CURRENT ZONES ALREADY REFLECT THIS WITH MINIMAL CHANGES NEEDED
THIS EVENING. MODELS CONTINUE TO HINT AT SOME RETURN MOISTURE AND
SOME STRATUS ON THE PLAINS AGAIN BY LATER TONIGHT SO WILL MAKE
SOME SKY COVER ADJUSTMENTS TO ACCOUNT FOR THIS.

&&

.SHORT TERM...(THIS EVENING THROUGH WEDNESDAY)
ISSUED AT 232 PM MDT TUE JUN 23 2015

BROAD UPPER RIDGE OVER THE SOUTHERN ROCKIES AND INTO THE SOUTHERN
PLAINS WILL KEEP WESTERLY FLOW ALOFT OVER THE STATE THROUGH
WEDNESDAY. AT THE SURFACE...HIGH PRESSURE OVER THE GREAT PLAINS
AND LOW PRESSURE OVER SOUTHEASTERN COLORADO IS BRINGING
SOUTHEASTERLY WINDS ACROSS THE FORECAST AREA. THIS HAS KEPT AN
INVERSION OVER THE PLAINS THROUGH THE DAY. AS INCREASED MOISTURE
MOVES UP FROM THE SOUTHEAST...AIRMASS WILL BE DESTABILIZING TO
ALLOW FOR ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS LATE
THIS AFTERNOON INTO THE EVENING....MAINLY SOUTH OF THE I-76. ABOVE
THE INVERSION...THE AIRMASS IS QUITE UNSTABLE...SO WITH THE
ADDITIONAL MOISTURE EXPECTED OVER THE SOUTHERN HALF OF THE
AREA...COULD SEE SOME STRONGER STORMS OVER THE PALMER DIVIDE AND
EAST INTO LINCOLN COUNTY. THESE STORMS WILL PUSH EAST THIS EVENING
WITH A SLIGHT CHANCE OF STORMS OVER THE FAR EASTERN PLAINS LATER
THIS EVENING. BIGGEST THREAT FROM THE STRONGER STORMS WILL BE HAIL
AND GUSTY WINDS...HOWEVER INCREASING SHEAR EARLY THIS EVENING MAY
BE ABLE TO ALLOW FOR A WEAK TORNADO TO FORM. AGAIN...THIS WILL
LIKELY BE SOUTH OF A LINE FROM DENVER TO AKRON. CONVECTION
EXPECTED OVER NEBRASKA TONIGHT MAY PUSH IN SOME STRATUS OR FOG
OVER THE FAR NORTHEAST CORNER.

EXPECT THE INVERSION OVER THE PLAINS TO BE ERODED BY WEDNESDAY FOR
SLIGHTLY WARMER TEMPERATURES OVER THE EASTERN PLAINS...HOWEVER
SLIGHTLY MORE MOISTURE MOVING IN FROM THE WEST WILL CAUSE MORE
CLOUD COVER. THIS WILL LIKELY COOL HIGH TEMPERATURES OVER THE HIGH
COUNTRY BY A COUPLE DEGREES OVER TODAY. LOOK FOR ISOLATED AFTERNOON
SHOWERS AND THUNDERSTORMS TO FORM OVER THE MOUNTAINS THEN PUSH
EAST OVER THE FRONT RANGE FOOTHILLS AND URBAN CORRIDOR.

.LONG TERM...(WEDNESDAY NIGHT THROUGH TUESDAY)
ISSUED AT 232 PM MDT TUE JUN 23 2015

WEDNESDAY NIGHT INTO THURSDAY...THE FLOW ALOFT WILL BE WESTERLY AS
A BROAD RIDGE OF HIGH PRESSURE STRETCHES ACROSS THE SOUTHERN U.S.
THE CENTER OF THE RIDGE WILL BE OVER THE SERN U.S ON THURSDAY WITH
THE MDLS ADVECTING SUBTROPICAL MOISTURE ACROSS NEW MX AND INTO CO.
THE CENTER OF THE RIDGE SHIFTS MORE TO THE FOUR CORNERS REGION BY
FRIDAY. A COLD FRONT ASSOCIATED WITH A PASSING TROUGH MOVING
INTO THE NORTHERN GREAT PLAINS WILL PUSH INTO NERN CO THURSDAY
NIGHT. AS THE RIDGE SHIFTS OVER THE WEST...THE FLOW ALOFT WILL
BECOME NORTHWESTERLY. BETTER MOISTURE BUT WITH COOLER TEMPERATURES
AND INCREASING SUBSIDENCE ALOFT...THE CHC OF TSTMS MAY BE LIMITED
FOR FRIDAY WITH THE BEST CHC NEAR THE HIGHER TERRAIN. THE RIDGE
CONTINUES TO BUILD OVER THE WESTERN U.S. SUNDAY THROUGH TUESDAY.
A WEAK NORTHERLY FLOW WILL BE OVER THE CWFA. TEMPERATURES WILL
WARM BACK UP BY EARLY NEXT WEEK BUT STILL ENOUGH MOISTURE AROUND
FOR SLGT CHC POPS OVER THE WEEKEND AND INTO EARLY NEXT WEEK IN THE
LATE AFTN/EVNG TIME FRAME.

&&

.AVIATION...(FOR THE TAFS THROUGH 06Z WEDNESDAY EVENING)
ISSUED AT 836 PM MDT TUE JUN 23 2015

STORMS HAVE ENDED AT TERMINALS FOR THIS EVENING WITH A RETURN TO
MAINLY DRAINAGE WINDS. COULD BE SOME STRATUS ON THE NORTHEAST
PLAINS BUT DON'T EXPECT THEM TO MAKE IT BACK TO TERMINALS. MORE
ISOLATED STORMS AGAIN FOR WED AFTERNOON WHILE SOUNDINGS SUGGEST
MORE MICRO BURST LOOKING WITH GUSTY WINDS THE MAIN THREAT WITH
LESS CAPE AND POTENTIALLY DRIER LOW LEVELS.

&&

.HYDROLOGY...
ISSUED AT 232 PM MDT TUE JUN 23 2015

ISOLATED THUNDERSTORMS EXPECTED THIS AFTERNOON INTO THIS
EVENING...BEGINNING AROUND THE FOOTHILLS AND PALMER DIVIDE THEN
MOVING OUT OVER THE EASTERN PLAINS. STORM MOTIONS SHOULD BE
ENOUGH FOR RAINFALL AMOUNTS TO STAY BELOW A QUARTER INCH OVER AN
AREA. SO NO FLOODING ISSUES ARE OF CONCERN FROM CONVECTION.

RIVERS REMAIN HIGH AND FAST DUE TO SNOWMELT BUT WILL CONTINUE TO
SLOWLY FALL THE NEXT FEW DAYS AS THE AVAILABLE SNOW DECREASES.
ANY RAINFALL OVER THE NEXT SEVERAL DAYS IS NOT EXPECTED TO HAVE AN
IMPACT ON THE LARGER RIVERS AND STREAMS.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR NORTHEAST AND NORTH CENTRAL
COLORADO.

.DAY ONE...TODAY AND TONIGHT

ISOLATED THUNDERSTORMS ARE POSSIBLE OVER THE FRONT RANGE AND IN
AREAS SOUTH OF DENVER LATE THIS AFTERNOON...THEN PUSHING OVER EASTERN
PLAINS THIS EVENING. STORMS THAT DO DEVELOP COULD BECOME SEVERE SOUTH

LARGE HAIL IS THE MAIN THREAT...BUT DAMAGING WINDS AND A TORNADO
ARE ALSO POSSIBLE. STORMS SHOULD BE OUT OF THE AREA BY MIDNIGHT.

SNOWMELT OVER THE HIGHER MOUNTAINS IS GRADUALLY DECREASING...BUT HIGH
WATER AND FAST FLOWS WILL CONTINUE IN RIVERS AND STREAMS OVER THE
NEXT SEVERAL DAYS.

.DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH MONDAY

A FAIRLY TYPICAL EARLY SUMMER WEATHER PATTERN WILL EXIST OVER THE
OUTLOOK AREA DURING THE PERIOD. TEMPERATURES WILL BE AROUND NORMAL
AS WILL THE CHANCES OF AFTERNOON AND EVENING THUNDERSTORMS.
PRECIPITATION WILL BE MOST LIKELY EAST OF THE CONTINENTAL DIVIDE.
ADDITIONALLY...ENOUGH INSTABILITY AND VERTICAL WIND SHEAR WILL
EXIST OVER LOWER ELEVATIONS TO KEEP AT LEAST A SMALL THREAT OF
ISOLATED SEVERE STORMS IN THE FORECAST.
