The radar

The Duluth radar (KDLH), 150 km from the middle of the area, began a volume at 22:54 UTC, the scan nearest the moment this went out.

Open the radar archive at this moment

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

International Fa, MN (KINL), launched 12:00Z, 10.9 hours before the alert went out and 175 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.

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

NWS Duluth, MN wrote its last area forecast discussion before this flash flood warning went out at Jul 5, 4:09 PM CDT, 1 hour 44 minutes earlier.

Area forecast discussion, Jul 5, 4:09 PM CDT, 1 hour 44 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DULUTH MN
409 PM CDT SAT JUL 5 2014

.SHORT TERM...(TODAY AND TONIGHT)
ISSUED AT 345 PM CDT SAT JUL 5 2014

THUNDERSTORMS CONTINUED LATE THIS AFTERNOON IN THE MINNESOTA
ARROWHEAD IN AN AREA OF STRONG LIFT ASSOCIATED WITH VORTICITY
LOBE. THIS FEATURE WILL BE MOVING TO THE EAST AND OUT OF THE AREA
THIS EVENING SO EXPECT THUNDERSTORMS IN THAT AREA TO DIMINISH.
THEN...OFF TO THE WEST..EXPECT MORE THUNDERSTORMS TO FIRE ALONG A
WARM FRONT THAT WAS ENTERING WRN MN LATE THIS AFTERNOON. TEMPS
AHEAD OF THE FRONT IN MN WERE IN THE LOW TO MID 80S WHILE BEHIND
THE FRONT THEY WERE IN THE MID 80S TO MID 90S. THE FRONT COULD BE
SEEN ON RADAR AND SATELLITE WHERE A LINE OF CONVECTION WAS
FORMING. AS THE NIGHT WEARS ON EXPECT THE MOIST AND VERY UNSTABLE
AIR MASS ASSOCIATED WITH THE FRONT WILL MOVE INTO THE NORTHLAND
CREATING THUNDERSTORMS. STRONG WAA...AND VERY UNSTABLE AIRMASS
ALONG WITH THE FROPA WILL BE THE INGREDIENTS FOR SOME VERY STRONG
OR SEVERE STORMS LATER TONIGHT. CURRENT MUCAPES ALONG THE FRONT
ARE IN THE 4-5 THOUSAND J/KG RANGE WITH SOME GOOD WIND SHEAR AND
HELICITY..SO SOME DISCREET SUPERCELLS POSSIBLE LATER TONIGHT. THE
TRAILING COLD FRONT STILL OVER THE HIGH PLAINS WILL MOVE INTO THE
NORTHLAND SUNDAY SO SCATTERED SHOWERS AND ISOLATE THUNDERSTORMS
WILL STILL BE A POSSIBILITY...ESPECIALLY OVR NWRN WI.

.LONG TERM...(SUNDAY THROUGH FRIDAY)
THE AREA OF HIGH PRESSURE WILL BUILD INTO THE FORECAST BEHIND THE
COLD FRONT SUNDAY NIGHT AND KEEP THE REGION DRY THROUGH MONDAY
MONDAY MORNING. A SERIES OF SHORTWAVES WILL MOVE THE FORECAST AREA
THROUGH WEDNESDAY MORNING CAUSING SCATTERED SHOWERS AND
THUNDERSTORMS TO DEVELOP THROUGH THE PERIOD. THE FIRST ONE MOVES
THROUGH MONDAY AND TUESDAY ALONG WITH AN UPPER LEVEL TROUGH.
CAUSING THUNDERSTORMS TO DEVELOP ACROSS THE FORECAST AREA. ANOTHER
SHORTWAVE WILL MOVE THROUGH THE REGION TUESDAY NIGHT AND WEDNESDAY
MORNING CAUSING ANOTHER ROUND OF SCATTERED SHOWERS AND
THUNDERSTORMS. THE COVERAGE WILL BE SCATTERED IN NATURE SO WILL
KEEP THE HIGH POPS IN THE GRIDS. WEAK HIGH PRESSURE WILL BUILD
INTO THE REGION WEDNESDAY AFTERNOON AND WEDNESDAY NIGHT BEFORE
ANOTHER SERIES OF SHORTWAVES MOVES THOUGH THE AREA. WILL KEEP THE
LOW POPS IN THE GRIDS SINCE COVERAGE AND TIMING IS TOUGH DUE TO
MODEL DIFFERENCES..

.AVIATION...(FOR THE 18Z TAFS THROUGH 18Z SUNDAY AFTERNOON)
ISSUED AT 102 PM CDT SAT JUL 5 2014

MAINLY VFR CONDITIONS AT TAF SITES EXCEPT FOR IFR/MVFR CONDTIONS
AT BRD DUE TO LOW STRATUS MOVING IN FROM THE WEST. THESE LOW
CLOUDS SHOULD IMPROVE TO VFR CONDITIONS BY LATE AFTERNOON. VFR
CONDITIONS WILL CONTIUNE INTO THE EVENING HOURS. HOWEVER...A
STRONG UPPER LEVEL DISTURBANCE WILL CAUSE SHOWERS AND
THUNDERSTROMS TO DEVELOP AND MOVE INTO THE NORTHERN AREAS AFTER
06Z. THIS AREA WILL SPREAD INTO THE OTHER TAF SITES AND MAY CAUSE
IFR/MVFR CONSTIONS LATE TONIGHT INTO SUNDAY MORNING.
