What was reported inside it

Time	Report	Where	Remark
Jul 15, 5:53 PM MDT	HAIL 0.75	4 Ese Shamrock, CO

Local storm reports filed while the alert was in force, from inside its polygon or its counties.

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, 11.8 hours before the alert went out and 34 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, Jul 15, 3:19 PM MDT, 2 hours 28 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DENVER/BOULDER CO
319 PM MDT FRI JUL 15 2005

.SHORT TERM...CURRENT RADAR IS INDICATING ISOLATED CONVECTION
BREAKING OUT OVER THE MOUNTAINS AND FOOTHILLS EAST OF THE DIVIDE.
OVER THE PLAINS...A FEW CUMULUS FIELDS ARE INDICATED ON SATELLITE
PICTURES BUT THATS ABOUT IT.  LAPS DATA SHOWS THE CIN IS GONE IN
MANY AREAS.  CAPES ARE AVERAGING ABOUT 2000 JOULES/KG OVER MOST OF
THE PLAINS.  THE CURRENT WATER VAPOR PICTURES SHOW SOME MOISTURE
TRAPPED UNDER THE RIDGE.  SURFACE OBSERVATIONS HAVE DEW POINTS IN
THE 50S OVER MOST OF THE PLAINS...WITH SOME 40S DOWNSTREAM OFF THE
PALMER RIDGE WITH THE SOUTHEASTERLY BOUNDARY LAYER FLOW.  FROM
YESTERDAY AT THIS TIME COMPARED TO NOW...THERE IS SLIGHTLY LESS
COVERAGE ON THE RADAR BUT THE SURFACE DEW POINTS ARE HIGHER TODAY.
WILL KEEP 20% GOING FOR THE PLAINS WITH THE CAPE AND BOUNDARIES
AROUND.  SKIES SHOULD CLEAR PRETTY WELL BY 06Z TONIGHT.  FOR
SATURDAY...THE THETA-E AXIS IS NOT AS SIGNIFICANT AS TODAYS.  THE
MOISTURE ON THE CROSS SECTIONS IS LESS THAN IT IS NOW AS WELL.
CAPES ARE LOWER AS WELL.  WILL GO 20%S IN THE HIGHER AREAS...10%S
ON THE PLAINS.  FOR TEMPERATURES...GRIDS SHOW SATURDAY 0.5-1.5 C
WARMER THAN TODAY.

.LONG TERM...BIGGEST CHANGE WILL BE COLD FRONT THAT IS PROGGED TO
COME INTO THE AREA SUNDAY.  THE COOLING SUNDAY WILL BE LIMITED BY
THE WARM START WE GET...BUT THIS SHOULD ALSO HELP STORM CHANCES
LATER IN THE DAY AS LOW LEVEL MOISTURE AND THETA-E AXIS BACK ACROSS
THE NORTHEAST PLAINS.  WILL INCREASE THUNDERSTORM CHANCES BY SUNDAY
EVENING WHEN STORMS MAY TRY TO BECOME MORE ORGANIZED ACROSS THE
PLAINS.  SEVERE STORMS WOULD BE POSSIBLE TOO AS 0-6 KM SHEAR
INCREASES TO 20 M/S AND CAPES EXPECTED TO RANGE FROM 1500-2500
J/KG.

MONDAY IS SHAPING UP TO BE SIGNIFICANTLY COOLER WITH MODELS SHOWING
700 MB TEMPS SUPPORTING HIGHS IN THE 70S.  GIVEN PAST PERFORMANCE OF
MODELS OVERDOING THE COOLING IN THESE EVENTS...WILL KEEP HIGHS IN
THE LOWER 80S FOR NOW.  IN ANY CASE...A NICE BREAK FROM THE 90S.

THE DRY AND VERY WARM CONDITIONS WILL RETURN THOUGH BY THE MIDDLE OF
NEXT WEEK.  ONLY ISOLATED HIGH BASED STORMS BY THEN AS AIRMASS DRIES
OUT AGAIN.  AT THIS POINT...WE CAN ONLY HOPE OF HURRICANE EMILY
REMNANTS GETTING INTO THE SOUTHWEST TO AID THE START OF THE MONSOON.

&&

.BOU...NONE.

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

.DAY ONE...TODAY AND TONIGHT

IT APPEARS THAT FAIRLY DECENT MOISTURE OVER THE PLAINS WILL STAY
AROUND THIS AFTERNOON TO HELP THE CHANCES OF PRECIPITATION.  LIKE
YESTERDAY...SCATTERED SHOWERS AND THUNDERSTORMS ARE EXPECTED TO
BEGIN OVER THE MAINTAINS AND FOOTHILLS BY 12:30 PM.  ISOLATED
SHOWERS AND THUNDERSTORMS ARE EXPECTED OVER THE FRONT RANGE PLAINS
BY 2 PM.  FURTHER EAST OVER THE PLAINS...ISOLATED SHOWERS AND
THUNDERSTORMS CAN BE EXPECTED AFTER 4 PM.  A FEW OF THE STORMS COULD
PRODUCE STRONG WIND GUSTS AND LARGE HAIL.

.DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY

A COLD FRONT IS EXPECTED TO DROP ACROSS THE AREA SUNDAY.  THIS WILL
BRING AN END TO THE VERY WARM TEMPERATURES...AND ALSO BRING A BETTER
CHANCE OF AFTERNOON AND EVENING THUNDERSTORMS.  A FEW OF THE STORMS
HAVE THE POTENTIAL TO BECOME SEVERE SUNDAY AND MONDAY AS LOW LEVEL
MOISTURE AND INSTABILITY WILL INCREASE BEHIND THE FRONT.

BY THE MID PART OF NEXT WEEK...DRIER CONDITIONS WILL RETURN WITH
JUST ISOLATED AFTERNOON AND EVENING THUNDERSTORMS PRODUCING GUSTY
WINDS BUT LITTLE RAINFALL.  HIGH TEMPERATURES ARE EXPECTED TO RETURN
INTO THE 90S ACROSS THE PLAINS.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION WILL NOT BE NEEDED TODAY OR TONIGHT.
