The radar

The Fargo/Grand Forks radar (KMVX), 95 km from the middle of the area, began a volume at 22:22 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 tornado 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

International Fa, MN (KINL), launched 12:00Z, 10.3 hours before the alert went out and 276 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 tornado warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Grand Forks, ND wrote its last area forecast discussion before this tornado warning went out at Jun 8, 2:20 PM CDT, 2 hours 59 minutes earlier.

Area forecast discussion, Jun 8, 2:20 PM CDT, 2 hours 59 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAND FORKS ND
220 PM CDT TUE JUN 8 2010

.SHORT TERM...
IMMEDIATE SHORT TERM CONCERN WILL BE SEVERE POTENTIAL EARLY THIS
EVENING THEN ATTENTION TURNS TO PERSISTENT RAIN CHANCES THRU THE
REST OF THE SHORT TERM. WILL FOLLOW A MODEL BLEND FOR THIS PORTION
OF THE FORECAST.

TONIGHT...CLEARING LINE TAKING FOREVER TO MOVE INTO EASTERN ND BUT
HAS NOW REACHED THE KDVL TO KJMS CORRIDOR. WIND SHIFT LINE/DRY
LINE CUTTING ACROSS THE CENTER OF ND WHERE SOME TSTMS HAVE ALREADY
DEVELOPED. SFC DEW POINTS AT KBIS/KMOT AT 48F WHERE KDVL/KJMS ARE
IN THE UPPER 50S. NICE SURGE OF DRY AIR COMING INTO THE WESTERN
HALF OF ND ON BREEZY WESTERLY WINDS. HAVE ABOUT 1000-1500 J/KG OF
SFC BASED CAPE IN THE ZONE WHERE THE TSTMS ARE FIRING. SPC MESO
CHARTS SHOWING SOME UPPER LEVEL DIVERGENCE JUST AHEAD OF THE LINE
OF STORMS WITH COOLER 500MB TEMPS ALSO MOVING INTO NORTH CENTRAL
ND. SOME LIMITING PARAMETERS MAY BE THAT THE STORMS ARE MOVING
INTO A MUCH COOLER AIRMASS WHERE IT HAS BEEN CLOUDY ALL DAY.
KGFK/KFAR HAVE ONLY REACHED THE LOWER 60S TODAY WITH FOG/LOW
CLOUDS. 0-6 KM BULK SHEAR VALUES ONLY ABOUT 30...SO NOT THE
STRONGEST THERE. SPC HAS ISSUED A MESOSCALE DISCUSSION TALKING
ABOUT A MARGINAL THREAT FOR SEVERE HAIL. WILL HAVE TO MONITOR THRU
THE LATE AFTERNOON. NICE SPINNING UPPER LOW JUST TO THE WEST OF
THE MANITOBA LAKES REGION. AS THIS WAVE MOVES ACROSS SOUTHERN
CANADA OVERNIGHT SOME SPOKES OF VORTICITY MAY ROTATE DOWN INTO
AREAS ALONG THE CANADIAN BORDER. WILL THEREFORE KEEP SOME CHANCES
FOR RAIN ALONG THE CANADIAN BORDER EVEN PAST MIDNIGHT.

WED-FRI...WILL KEEP SOME LINGERING SHOWERS AROUND THE NORTHEAST FA
ON WED MORNING AS THE UPPER LOW MOVES ACROSS. REST OF THE DAY
SHOULD BE QUIET BUT COOL AS A BACK DOOR COLD FRONT DROPS DOWN THE
VALLEY THRU THE DAY. 850MB TEMPS COOL TO 6-8C. NEXT CHANCE OF RAIN
LOOKS TO BE THU/THU NIGHT. 12Z MODELS SHOW BETTER CHANCES FOR RAIN
ON THU ITSELF SO HAVE UPPED PCPN CHANCES JUST A BIT. FORECAST
ALREADY HAD LIKELY PCPN CHANCES FOR THU NIGHT AND WILL LEAVE THOSE
INTACT. SOME MODELS SHOWING THE MAIN BATCH OF PCPN MOVING TOWARD
THE MN ARROWHEAD WHILE OTHERS ARE A LITTLE FURTHER NORTH...SO THE
JURY IS STILL OUT. LOTS OF AVAILABLE MOISTURE WITH THE THU/THU
NIGHT SYSTEM AS PRECIPITABLE WATER VALUES JUMP UP TO OVER 1.50
INCHES. MODELS SEEM TO AGREE BEST PCPN CHANCES WILL BE ACROSS WEST
CENTRAL MN ON FRI SO NO CHANGES THERE.

.LONG TERM [SAT-TUE]...
A FAIRLY ROBUST SHRTWV TROF CUTS ACROSS THE NRN PLAINS THROUGH THE
EARLY PART OF THE WEEKEND... WITH SOME RESIDUAL CLOUDS AND A THREAT
OF SHOWERS LINGERING THROUGH SUNDAY. A DRIER H5 RIDGE PATTERN SHOULD
DOMINATE THE EARLY WEEK PERIOD... PRODUCING SEASONABLY WARM AND
SUNNY CONDITIONS. THE NEXT SHRTWV TROF SHUD DEVELOP A SOUTHWESTERLY
FLOW PATTERN ALOFT BY TUESDAY... WITH CONVECTIVE ACTIVITY TO
ACCOMPANY.

&&

.AVIATION...
PERSISTENT IFR CIGS AND VSBYS ALG AND EAST OF THE RED RIVER WILL
SHIFT SLOWLY EWD AHEAD OF APPCHG SFC TROF THROUGH THE AFTERNOON.
SHOWERS SHUD DIMINISH THROUGH LATE AFTERNOON IN NWRN MN WITH SCT
TSTMS DEVELOPING FROM LATE AFTERNOON INTO EARLY EVENING. WEST OF
THE RED RIVER WILL SEE GENLY VFR CONDS WITH SCT TSTMS MOVING WEST
TO EAST ACROSS THE AREA THROUGH MID AND LATE AFTERNOON.

.FGF WATCHES/WARNINGS/ADVISORIES...
