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 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

Glasgow Intl Airport, MT (KGGW), launched 12:00Z, 9.6 hours before the alert went out and 217 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 17, 2:25 PM MDT, 1 hour 13 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GLASGOW MT
225 PM MDT TUE JUN 17 2014

.SHORT TERM...FOR NORTHEAST MONTANA...TONIGHT THROUGH THURSDAY...
DEEP MOISTURE IS IN PLACE ACROSS NORTHEAST MONTANA THIS
AFTERNOON...SETTING THE STAGE FOR A GOOD PRECIP EVENT ACROSS MOST OF
THE AREA.

THE INITIAL PUSH OF PRECIPITATION ASSOCIATED WITH A LARGE UPPER
LOW OVER THE NORTHERN ROCKIES HAS CLEARED ALL BUT THE FURTHEST
NORTHERN REACHES OF NORTHEAST MONTANA AS OF 2 PM THIS AFTERNOON.
FURTHER SOUTH A LINE OF STRONG TO SEVERE THUNDERSTORMS IS ERUPTING
ALONG A STALLED FRONTAL BOUNDARY FROM BAKER THROUGH CIRCLE TO FORT
PECK. A TORNADO WATCH IS IN EFFECT...AND THESE STORMS WILL NEED TO
BE MONITORED FOR HAIL...HEAVY RAIN...AND POSSIBLE TORNADOES
THROUGH THE EVENING HOURS. EXPECT AFTER THE DEEP INSTABILITY IS
CHEWED UP A CONVECTIVE COMPLEX WILL SET UP...KEEPING EXCELLENT
CHANCES FOR PRECIP GOING ACROSS THE EAST OVERNIGHT. GUSTY EASTERLY
WINDS WILL ALSO CONTINUE THROUGH THE EVENING HOURS THANKS TO
ONGOING CONVECTION AND A TIGHTENED PRESSURE GRADIENT AT THE
SURFACE. THUS ISSUED A LAKE WIND ADVISORY FOR FORT PECK LAKE.

WEDNESDAY MORNING PRECIPITATION WILL BEGIN TO TAPER OFF SOME FROM
SOUTH TO NORTH AS THE VERTICALLY STACKED LOW WRAPS IN DRIER AIR
FROM THE SOUTH. HOWEVER...WITH LINGERING MOISTURE FROM TONIGHTS EXPECTED
PRECIPITATION EVENT...SHOWERS AND POSSIBLE THUNDERSTORMS WILL CONTINUE
TO DEVELOP IN A SCATTERED FASHION.

WEDNESDAY NIGHT INTO THURSDAY THE UPPER LOW SLOWLY DRIFTS EASTWARD
OVER NORTHEAST MONTANA. EXPECT CONTINUED SCATTERED
SHOWER/THUNDERSTORM ACTIVITY THANKS TO LINGERING MOISTURE AND INSTABILITY
DRIVEN BY THE LOW OVERHEAD. GILCHRIST

.LONG TERM...THURSDAY NIGHT THROUGH TUESDAY...
WITH CONTINUED CONCERNS REVOLVING AROUND THE CLOSED LOW IN THE
SHORT TERM...NO CHANGES WERE MADE TO THE GOING LONG TERM FORECAST.
GILCHRIST

PREVIOUS LONG TERM DISCUSSION...BY THURSDAY NIGHT...THIS SLOW
MOVING STORM SYSTEM WILL FINALLY BE PUSHING NORTHEAST OUT OF OUR
CWA...BUT WHAT FORM IT TAKES AS IT LEAVES IS UNCERTAIN AS THE GFS
WANTS TO KEEP IT AS ONE LARGE CLOSED LOW AND THE EC WANTS SPLIT IT
INTO TWO SEPARATE SMALLER LOW CENTERS. LATE THURSDAY THROUGH LATE
FRIDAY...A FEW LINGERING SHOWERS OR ISOLATED THUNDERSTORMS COULD
IMPACT PORTIONS OF NORTHEAST MONTANA.

REGARDLESS OF THE DEPARTING STORM SYSTEM...WEAK UPPER-LEVEL RIDGING
TAKES OVER EARLY SATURDAY THROUGH EARLY SUNDAY KEEPING PRECIPITATION
AWAY FROM NORTHEAST MONTANA FOR THE MOST PART.

SUNDAY NIGHT AND BEYOND...MODELS SHOWING A BROAD AREA OF BENIGN
LARGE-SCALE FLOW...BUT STILL WITH ENOUGH MODEL DIFFERENCES THAT
WARRANTED A GFS/EC BLEND WITH CLIMO POPS TO ACCOUNT FOR THE
UNCERTAINTY THIS FAR OUT IN THE FORECAST PERIOD. THERE DOES NOT
SEEM TO BE ANY SIGNIFICANT STORM SYSTEMS SET TO IMPACT OUR REGION
IN THE EXTENDED FORECAST PERIOD.

TEMPERATURES THROUGHOUT THE FORECAST PERIOD WILL GRADUALLY CLIMB
TO ABOVE NORMAL LEVELS FOR THIS TIME OF YEAR. BMICKELSON

&&

.AVIATION...

SYNOPSIS: AN UPPER LOW FROM THE PACIFIC NORTHWEST WILL CONTINUE
DIRECTING SHOWERS AND THUNDERSTORMS ACROSS NORTHEAST MONTANA
THROUGH THE EVENING AND OVERNIGHT HOURS. BEST CHANCES FOR
WIDESPREAD ACCUMULATING PRECIPITATION IS DURING THE AFTERNOON AND
EVENING HOURS TODAY. LARGE HAIL AND DAMAGING WINDS WILL BE
POSSIBLE OVER THE LOWER YELLOWSTONE RIVER VALLEY...INCLUDING THE
KSDY AND KGDV TERMINALS.

FLIGHT CATEGORY: VFR BECOMING MVFR THIS AFTERNOON WITH VCTS AT MOST
LOCATIONS. IF A STORM HAPPENS TO PASS DIRECTLY OVER A TAF
SITE...LIFR CONDITIONS OR WORSE WOULD BE LIKELY UNDER HEAVY
RAINFALL. EXPECT AMENDMENTS THIS THROUGH THIS EVENING. MVFR CIGS
ARE EXPECTED TO LINGER INTO WEDNESDAY MORNING AS SHOWERS PERSIST
ACROSS THE REGION.

WINDS: EASTERLY WINDS UP TO 30 MPH ARE POSSIBLE TODAY AND COULD
BECOME VARIABLE AND GUSTIER NEAR THE STRONGER STORMS. WINDS ARE
EXPECTED TO SLACKEN SOME OVERNIGHT TONIGHT BEFORE AGAIN BECOMING
GUSTY WEDNESDAY MORNING. BMICKELSON/GILCHRIST
