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.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BISMARCK ND
350 PM CDT FRI JUL 2 2004

.SHORT TERM...
FORECAST PROBLEMS IN THE SHORT TERM ARE CONVECTION CHANCES AND
TIMING. ACTUALLY NO SIGNIFICANT CHANGES FROM WHAT WE ALREADY HAVE
GOING. IN THE NEAR TERM...UNSTABLE ATMS THIS AFTERNOON WITH LIFTED
INDEX -2 TO -6 ACROSS MUCH OF CWA. MODIFIED MESOETA SOUNDINGS
INDICATED SOME PRETTY DECENT HELICITY OVER FAR EASTERN CWA. GROUND
TRUTH REPORT OF FUNNEL CLOUD VERIFIES POTENTIAL FOR ROTATING STORMS.
CURRENT TORNADO WATCH ALONG AND EAST OF TROUGH LINE THAT CUTS
THROUGH DICKEY AND LAMOURE COUNTIES. THIS WILL RUN UNTIL 9 PM CDT.
ALTHOUGH STILL VERY UNSTABLE...SHEAR IS MUCH LESS OVER REST OF
WESTERN AND CENTRAL CWA...SO MAIN THREAT WILL BE A POSSIBLE
DOWNDRAFT GUST IN AN ISOLATED SEVERE CELL. CHANCES ARE SLIM ENOUGH
THAT WILL NOT MENTION SEVERE EXCEPT FOR WATCH AREA. HEAVY RAIN IS
ALSO LIKELY AS PLENTY OF LOW LEVEL MOISTURE AVAILABLE.

SECONDARY FRONT DROPS SOUTH THROUGH CWA ON SATURDAY. STILL ENOUGH
INSTABILITY AROUND WITH DAYTIME HEATING TO MENTION ANOTHER CHANCE OF
THUNDERSTORMS. MORE SIGNIFICANT SYSTEM TAKING SHAPE FOR SUNDAY NIGHT
AND MONDAY AS SHORTWAVE TROUGH DEVELOPS A SURFACE INVERTED TROUGH
INTO SOUTHERN NORTH DAKOTA. SOME TIMING DIFFERENCES BETWEEN ETA/GFS
BUT BOTH BRING CHANCE OF THUNDERSTORMS TO WESTERN AND CENTRAL NORTH
DAKOTA ON MONDAY.

.LONG TERM...
MONDAY NIGHT THROUGH FRIDAY...AFTER SOME WRAP AROUND LINGERING
SHOWERS MONDAY NIGHT IN EASTERN COUNTIES...WEAK SURFACE HIGH
PRESSURE MOVES INTO THE NORTHERN PLAINS OUT OF CANADA. GUIDANCE
CONTINUES TO KEEP TEMPERATURES COOLER ON TUESDAY...AND I TRENDED
DOWN HIGHS ONCE AGAIN. NORTHWEST FLOW ALOFT TURNS SOUTHWEST BY
WEDNESDAY NIGHT...AS H500 RIDGE AXIS MOVES INTO THE NORTHERN
PLAINS...AND THEN SLOWLY EASTWARD. THIS WILL SET UP AN ACTIVE
SCENARIO FOR THE END OF THE WORK WEEK. I SET UP WARMING TREND
WEDNESDAY...HIKING UP TEMPERATURES THURSDAY AND FRIDAY.

.BIS WATCHES/WARNINGS/ADVISORIES...
NONE.
