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.

CHANCE OF CONVECTIVE PRECIPITATION THROUGH MONDAY NIGHT.

.LONG TERM...TUESDAY THROUGH FRIDAY. ON TUESDAY THE H500 RIDGE IS TO
THE WEST WITH NWLY FLOW ALOFT OVER ND...BUT THE GFS CONTINUES TO
BRING A SMALL VORT/SHORTWAVE THROUGH THE RIDGE AND WILL KEEP LOW

CONTINUES TO BUILD NEXT WEEK AND NORTH DAKOTA IS ON THE EASTERN EDGE
OF THIS RIDGE. THIS WILL ALLOW SEASONABLE MAX TEMPS IN THE 80S WITH
LOWS IN THE UPPER 50S TO LOWER 60S. ON FRIDAY THE GFS SHOWS A
RIPPLE OR FLATTENING OF THE RIDGE AND VORT ENERGY MOVING
THROUGH...SO INTRODUCED PRECIP ON FRIDAY NIGHT.
