What was reported inside it
| Time | Report | Where | Remark |
|---|---|---|---|
| Aug 23, 4:53 PM MDT | HEAVY RAIN 0.78 | Glenwood Springs, 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 flash flood 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
Grand Junction, CO (KGJT), launched 12:00Z, 10.5 hours before the alert went out and 110 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.

408 PM MDT FRI AUG 23 2013
.SHORT TERM...(TONIGHT THROUGH SATURDAY NIGHT)
ISSUED AT 408 PM MDT FRI AUG 23 2013
REGIONAL PROFILERS AND WATER VAPOR IMAGERY SHOWING THE UPPER RIDGE
MOVING INTO THE HIGH PLAINS THIS AFTERNOON. SATELLITE ALSO SHOWING A
STRONG TROPICAL AND MONSOONAL TAP SWEEPING INTO THE DESERT SOUTHWEST
AND BEING DRAWN NORTHEASTWARD INTO THE GRADIENT FLOW PRODUCED BY THE
UPPER RIDGE AND LOW PRESSURE APPROACHING THE WEST COAST. WATER VAPOR
AND DYNAMIC TROP PRESSURE FIELDS ALSO SHOWED A VERY DISTINCT PV LOBE
ROTATING THROUGH THE 4 CORNERS THIS MORNING. FOLLOWING THIS IS A
SECOND WAVE LIFTING THROUGH THE MOISTURE PLUME INTO SOUTHEAST UTAH
THIS AFTERNOON. PWATS STILL HOVERING WELL ABOVE NORMAL WHICH WHEN
COMBINED WITH THE INSTABILITY ON THE NOSE OF THE PV LOBE...LED TO A
VIGOROUS OUTBREAK IN THE CONVECTION THIS AFTERNOON. STRONG OUTFLOW
WINDS...HEAVY DOWNPOURS AND EVEN SMALL HAIL WILL CONTINUE TO BE A
THREAT THROUGH THE MID EVENING HOURS.
THE UPPER RIDGE WILL CONTINUE TO SLIDE EASTWARD OVER THE NEXT 24 TO
36 HOURS PULLING THE MOISTURE PLUME OVER CENTRAL UTAH INTO OUR CWA
BEGINNING OVERNIGHT. MODEL THETA SURFACES AT 325K SHOW MOISTURE
ADVECTION LEAVING PWATS UP NEAR AN INCH. WEAK ASCENT WILL ALSO BE
SLIDING ACROSS THE COLORADO/UTAH BORDER AND SHOULD LEAVE ISOLATED TO
SCATTERED SHOWERS AND THUNDERSTORMS DRIFTING NORTHWARD THROUGH THE
OVERNIGHT HOURS. MOISTURE REMAINS IN PLACE OVER OUR CWA GOING INTO
TOMORROW AFTERNOON AND MID LEVEL SHEAR REMAINS STRONG DUE THE
GRADIENT FLOW. THEREFORE ANOTHER ROUND OF CONVECTION LOOKS ON TRACK
AS A SERIES OF TRANSIENT WAVES LOOK TO MOVE THROUGH THE FLOW. STORMS
WILL AGAIN BE ON THE MOVE SO FLOODING SHOULD BE LIMITED TO LOCALIZED
AREAS. THE THREAT OF STRONG WIND GUSTS AND SMALL HAIL WILL BE
POSSIBLE AS WELL. HIGHS LOOK TO BE IMPACTED BY THE MORE ACTIVE
WEATHER AND DID LOWER THEM SLIGHTLY TOWARD THE COOLER MET GUIDANCE.
MOISTURE TRANSPORT VECTORS SHOW A STRONG TAP TO THE TROPICS AGAIN
SATURDAY NIGHT...NOSING INTO THE 4 CORNERS BY SUNRISE ON SUNDAY.
THIS SHOULD KEEP A THREAT OF SHOWERS GOING...WITH THE BEST CHANCES
OVER OUR SOUTHWEST CWA.
.LONG TERM...(SUNDAY THROUGH FRIDAY)
ISSUED AT 408 PM MDT FRI AUG 23 2013
DEEP LAYERED MOISTURE ADVECTION FROM IVO AND OLD MEXICO SPREADS
NORTH OVER UTAH ON SUNDAY. FOR OUR FORECAST AREA...THE BEST
ISENTROPIC UPGLIDE AND SPEED SHEAR WILL BE POSITIONED OVER
NORTHEAST UTAH. PARTS OF WESTERN COLORADO WILL BE ON THE ERN EDGE
OF THIS MOISTURE PLUME. WITH PROGGED PWATS REACHING (POSSIBLY
EXCEEDING) THE CLIMATOLOGICAL EXTREME ON THE HIGH END...THERE IS
CONCERN ON FLASH FLOODING POTENTIAL. ANOTHER WAY TO LOOK AT
THIS...700 MB SPECIFIC HUMIDITY EXCEEDS 10 G/KG FOR THE WRN HALF
OF OUR FORECAST AREA (THAT IS A LOT OF REAL ESTATE FOR SUCH
VALUES). FLOODING POTENTIAL MAY BE MITIGATED BY EXTENSIVE CLOUD
COVER THAT LIMITS CONVECTIVE POTENTIAL...BUT WIDESPREAD
SIGNIFICANT RAINS MAY STILL BRING AN ELEVATED RISK OF FLOODING.
THE FLASH FLOOD POTENTIAL MAY BE POSITIONED FARTHER EAST THAN WHAT
MODEL QPF MAY SUGGEST...CONVECTIVE POTENTIAL MAY BE HIGHER OF THE
ERN EDGE OF THE DEEP MOISTURE FEED DUE TO DIFFERENTIAL HEATING.
GIVEN THE DEEP LAYERED SPEED SHEAR...TRAINING ECHOS MAY OCCUR OVER
THE NERN COLORADO PLATEAU THAT IS MORE PRONE TO FLASH FLOODING.
THIS THREAT EXTENDS INTO MONDAY (POSSIBLY INTO TUESDAY MORNING) AS
DEEP MOISTURE STREAMS ACROSS UTAH. THERE IS STILL SOME UNCERTAINTY
ON HOW THIS EVOLVES AS EACH MODEL SHOWS DIFFERENT QPF AMOUNTS...BUT
THEY ALL ARE WET AND THEREFORE FORECASTS SHOULD STRONGLY LEAN
TOWARD A SIGNIFICANT RAIN EPISODE ACROSS THE NERN HALF OF OUR
FORECAST AREA. GIVEN THE ANOMALY OF THIS EVENT...WITH
COORDINATION WITH SLC AND WPC DAY 3 GUIDANCE...WILL ISSUE A RARE
DAY 2 AND DAY 3 FLASH FLOOD WATCH FOR EASTERN UTAH FROM SUNDAY
AFTERNOON THROUGH MONDAY AFTERNOON.
WEDNESDAY THROUGH FRIDAY...NOT AS WET BUT THE RAIN PROBABILITIES
REMAIN ABOVE CLIMOTOLOGICAL NORM. AIR MASS REMAINS CONDITIONALLY
UNSTABLE WITH SCATTERED STORMS OVER THE HIGHER TERRAIN. SUFFICIENT
MID LEVEL FOR A FEW OF THESE STORMS TO MOVE ACROSS THE LOWER
VALLEYS.

.AVIATION...(FOR THE 00Z TAFS THROUGH 00Z SATURDAY EVENING)
ISSUED AT 408 PM MDT FRI AUG 23 2013
THUNDERSTORMS WILL CONTINUE TO LIFT NORTHEAST ACROSS WESTERN
COLORADO AND NORTHEAST UTAH THROUGH 03Z. VERY STRONG WIND
GUSTS AND HEAVY RAINFALL COULD IMPACT THE KASE AND KEGE FLIGHT
TERMINALS THROUGH THIS TIME AND CREATE HAZARDOUS FLYING
CONDITIONS. MOUNTAIN OBSCURATIONS WILL BE POSSIBLE OVERNIGHT AS
SHOWERS AND THUNDERSTORMS WILL PERSIST THROUGH THE EARLY MORNING
HOURS. MOISTURE AND LIFT REMAIN OVER THE REGION ON SATURDAY AND
SHOWERS AND THUNDERSTORMS WILL SPREAD IN COVERAGE THROUGH THE
EARLY AFTERNOON HOURS. THUNDERSTORMS AT OR IN THE VICINITY OF MANY
OF FLIGHT TERMINALS WILL BE POSSIBLE.
