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 (KDNR), launched 12:00Z, 10.1 hours before the alert went out and 284 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
NATIONAL WEATHER SERVICE PUEBLO CO
230 PM MDT FRI JUN 25 2004

.SHORT TERM...
(TONIGHT AND SATURDAY)

CURRENTLY: CURRENT SATTELITE IMAGERY AND H5 RUC ANALYSIS SHOW AN
UPPER LEVEL RIDGE OVER THE DESERT SW...WITH NW FLOW ACROSS THE
ROCKIES. DISTURBANCES IN THE UPPER FLOW HAVE BEEN KICKING OFF
CONVECTION SINCE EARLY THIS MORNING...AND BY THE AFTN LTG WAS
WIDESPREAD ACROSS THE GREAT BASIN AND ROCKIES. FOR THE CWA...SFC
HIGH PRES OVER THE CENT PLAINS WAS KEEPING EASTERLY FLOW ACROSS THE
E CO PLAINS.

COMBINATION OF UPPER DISTURBANCE AND LOW LEVEL EASTERLY FEED OF
MOISTURE WILL CONTINUE CONVECTION THROUGH THE EVENING...WITH PRECIP
ENDING LATE OVER THE FAR E PLAINS AFTER MIDNIGHT. LOOKING AT SEVERE
PARAMETERS...META CAPE AT 1000-1300 J/KG AND LOW SHEAR AT AROUND 30
KTS COULD MEAN ISOLATED LARGE HAIL AND DAMAGING WINDS THIS EVENING.
LATEST NUMERICAL GUIDANCE INDICATED SLIGHTLY MINIMUMS...AND WITH
THE STRUGGLE TO WARM TODAY FELT THIS WAS REASONABLE. AS FOR
TOMORROW...LOOKS AS IF SATURDAY SHOULD BE A REPEAT OF TODAY...WITH
META MODEL INDICATING SLIGHTLY HIGHER CAPES AND 0-6 KM BULK SHEAR
DURING THE AFTN.

.LONG TERM...
(SATURDAY NIGHT THROUGH FRIDAY)

VERY PERSISTENT WEATHER PATTERN LOOKS TO STAY IN PLACE THROUGH THE
EXTENDED PERIOD...WITH A WEAK UPPER RIDGE OVER THE DESERT SW UP
INTO THE GREAT BASIN...AND NW FLOW WITH MULTIPLE DISTURBANCES ACROSS
THE STATE. SFC PRES MAPS INDICATE THAT HI PRESSURE OVER THE CENTRAL
US PLAINS WILL EVENTUALLY START MOVING OUT TUES NIGHT...EASING THE
UPSLOPE EASTERLY FLOW. LOW LEVEL MOISTURE MIGHT START DRYING OUT THE
SECOND HALF OF NEXT WEEK...LOWERING THE DAILY THUNDERSTORM CHANCE TO
ISOLATED...AND ALLOWING MAX TEMPS TO GRADUALLY WARM. THIS IS
REFLECTED IN THE ONGOING GRIDS...AND FOUND LITTLE THAT NEEDED
ADJUSTING...OTHER THAN SLIGHT TWEAKING. WITH ABUNDANT MOISTURE IN
PLACE (DEWPOINTS IN THE 40S AND 50S)...DIURNAL CONVECTION IS ALMOST
ASSURED EACH DAY THROUGH TUESDAY...THEN TAPERING OFF WED THROUGH FRI.
EXPECT CONVECTION TO FIRE OFF OVER THE HIGHER TERRAIN EACH DAY BY 12
NOON...THEN SLOWLY MOVE E-SE ACROSS THE ADJACENT PLAINS DUE TO
LIGHTER H7 WINDS. MOORE//
