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.

AREA FORECAST DISCUSSION...UPDATED TO ADD WWA NATIONAL WEATHER SERVICE GLASGOW MT 250 PM MDT SUN JUL 11 2004 .SHORT TERM...FOR NORTHEAST MONTANA TONIGHT THROUGH TUESDAY...SEVERE WEATHER THREAT STILL A POSSIBILITY THIS AFTERNOON. PACIFIC TROUGH STILL APPROACHING WITH ASSOCIATED COLD FRONT YET TO MAKE PUSH THROUGH THE FORECAST AREA. ATMOSPHERE VERY UNSTABLE ALONG SURFACE TROUGH AXIS AS EVIDENT BY SPECIAL KGGW SOUNDING FROM EARLY THIS AFTERNOON. CAPPING INVERSION AROUND 850 MB LEVEL SHOULD EASILY BE BROKEN AS FRONT APPROACHES. VERY JUICY AIR CONTINUING TO WORK IN ON SOUTHEAST WINDS AT THE SURFACE WITH READINGS AS HIGH AS THE UPPER 60S TO AROUND 70. THETA-E RIDGE ALSO IN PLACE AND SET TO PROGRESS EAST AHEAD OF FRONT.

MODELS ALSO NOW HINTING AT A BIT OF A JET COUPLET OVER NORTHEAST CORNER OF THE FORECAST AREA. THIS COMBINED WITH OTHER LARGER SCALE LIFT FROM UPPER TROUGH WILL KEEP SEVERE THREAT GOING INTO THE EVENING HOURS. MODELS HAVE SLOWED DOWN FRONTAL PASSAGE AS EXPECTED...SO HAD TO SHIFT POPS AND SEVERE WORDING A LITTLE LATER THAN INHERITED FORECAST. AFTER FRONT PASSES THROUGH...SURFACE HIGH PRESSURE WITH STRONG SUBSIDENCE WORKS IN. EXPECT COOLER POST-FRONTAL TEMPERATURES ON MONDAY WITH DRIER CONDITIONS FROM VERY DRY AIRMASS MOVING IN. MADE VERY FEW CHANGES TO FORECAST THROUGH TUESDAY AS DRY AND WARM CONDITIONS CONTINUE UNDER INFLUENCE OF UPPER RIDGE. JAZ .LONG TERM...TUESDAY NIGHT THRU SUNDAY.. GENERAL AGREEMENT IN MODELS WITH UPPER LEVEL TROUGH SITTING OVER NORTHEAST MONTANA FOR EXTENDED PERIOD. THIS SHOULD BRING WARM AND DRY CONDITIONS FOR THE WEEK. A SHORT WAVE MOVES THROUGH NORTHEAST CORNER OF MONTANA OR JUST MISSES IT SO HAVE LEFT POPS IN FOR NORTHEAST CORNER ON FRIDAY AFTERNOON AND EVENING. HOWEVER... DECREASED POPS ALONG SOUTHERN BORDER AND WESTERN BORDER. TEMPERATURES WILL BE ABOVE NORMAL THE ENTIRE EXTENDED PERIOD. TLSJR && .GGW WATCHES/WARNINGS/ADVISORIES...
