The radar

The Aberdeen radar (KABR), 89 km from the middle of the area, began a volume at 22:37 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

Aberdeen, SD (KABR), launched 12:00Z, 10.6 hours before the alert went out and 149 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.

What forecasters said that day

The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Bismarck, ND wrote its last area forecast discussion before this severe thunderstorm warning went out at May 25, 3:38 PM CDT, 1 hour 56 minutes earlier.

Area forecast discussion, May 25, 3:38 PM CDT, 1 hour 56 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BISMARCK ND
338 PM CDT SUN MAY 25 2014

.SHORT TERM...(THIS EVENING THROUGH MONDAY)
ISSUED AT 338 PM CDT SUN MAY 25 2014

A LINE OF THUNDERSTORMS ARE EXTENDING ALONG A LINE FROM GRAND
FORKS TO JAMESTOWN INTO ASHLEY. THIS LINE IS ASSOCIATED WITH A
COLD FRONT SLOWLY MAKING ITS WAY EAST ACROSS EASTERN NORTH DAKOTA.
THE CONVECTIVE ACTIVITY WILL CONTINUE OVER THE JAMES RIVER BASIN
DURING THE NEXT FEW HOURS...WITH HEAVY RAIN AND LOCALIZED FLOODING
BEING THE PRIMARY THREAT. SMALL HAIL AND GUSTY WINDS WILL ALSO BE
POSSIBLE.

WEAK HIGH PRESSURE BUILDING INTO THE REGION SHOULD PUT AN END TO
CONVECTIVE ACTIVITY THIS EVENING...WITH TRANQUIL CONDITIONS
FORECAST OVERNIGHT.

FOR MONDAY...A WARM FRONT IS FORECAST TO LIFT INTO SOUTHERN
SASKATCHEWAN BY THE AFTERNOON. THIS FEATURE COULD PROVIDE FOCUS
FOR THUNDERSTORM DEVELOPMENT OVER NORTHWESTERN NORTH DAKOTA MONDAY
AFTERNOON. WITH MUCAPE INCREASING TO 1000-1500 J/KG AND 0-6KM
SHEAR AROUND 40 KNOTS...SOME OF THESE STORMS OVER NW ND COULD
PRODUCE LARGE HAIL AND DAMAGING WINDS.

.LONG TERM...(MONDAY NIGHT THROUGH SUNDAY)
ISSUED AT 338 PM CDT SUN MAY 25 2014

OVERALL A SOUTHWEST FLOW IS MAINTAINED INTO NORTH DAKOTA WITH THE
MAIN JET REMAINING NORTH AND WEST OF THE STATE...STRETCHING FROM THE
NORTHERN ROCKIES INTO SOUTHERN CANADA. MULTIPLE...BUT WEAK
DISTURBANCES WITHIN THIS FLOW WILL PERIODICALLY TRIGGER A CHANCE OF
SHOWERS AND THUNDERSTORMS. THE HIGHEST CHANCES APPEAR WEST AND
NORTH...CLOSEST TO THE UPPER JET DYNAMICS VERSUS SOUTH AND EAST. A
LONGWAVE TROUGH WILL REMAIN IN TACT AND DEEPEN AT TIMES ALONG THE
WEST COAST...RESULTING IN A BRIEF AMPLIFICATION OF AN UPPER RIDGE
ACROSS CENTRAL/EASTERN NORTH DAKOTA THURSDAY AND POSSIBLY LASTING
INTO FRIDAY. DISCREPANCIES ON HOW THE GFS AND ECMWF HANDLE THIS
BRIEF RIDGE CREATES A LOW FORECAST CONFIDENCE ON CHANCES OF
PRECIPITATION AND AREAL COVERAGE ACROSS WESTERN AND CENTRAL NORTH
DAKOTA. HOWEVER BOTH THE GFS AND ECMWF CONTINUE TO SHOW A GROWING
CONSENSUS FOR A STRONGER SHORTWAVE TO PRODUCE WIDESPREAD
SHOWERS/THUNDERSTORMS OVER CENTRAL NORTH DAKOTA FRIDAY EVENING
THROUGH SATURDAY. H85 TEMPS AROUND +20C TO +22C WILL YIELD HIGHS IN
THE 80S GIVEN A DECENT AMOUNT OF SUNSHINE AND MIXING...LITTLE COOLER
IF THIS IS NOT ACHIEVED. OVERNIGHT LOWS IN THE 50S THROUGH THE LONG
TERM PERIOD.

&&

.AVIATION...(FOR THE 18Z TAFS THROUGH 18Z MONDAY AFTERNOON)
ISSUED AT 338 PM CDT SUN MAY 25 2014

DRIER AIR FILTERING INTO WESTERN NORTH DAKOTA SHOULD KEEP KISN-
KDIK-KMOT-KBIS DRY THROUGH THE REMAINDER OF THE 18Z TAF PERIOD.
OTHERWISE...SCATTERED TO NUMEROUS THUNDERSTORMS ARE EXPECTED TO
CONTINUE NEAR KJMS THROUGH 22Z THIS AFTERNOON. OTHERWISE...THUNDERSTORMS
WILL TAPER OFF LATE AFTERNOON WITH VFR CONDITIONS AREAWIDE TONIGHT
THROUGH MONDAY MORNING.

NOTE...PARTS ARE ON ORDER FOR THE KISN ASOS. TECHNICIANS WILL BE
ON-SITE TROUBLESHOOTING THE KISN ASOS ON MEMORIAL DAY. RETURN TO
SERVICE IS EXPECTED BY MONDAY AFTERNOON. WILL CONTINUE TO CARRY
AMD NOT SKED FOR THE KISN TAF AS A RESULT.
