The Twin Cities NWS office issued a report today confirming that the tornado outbreak on June 17th set the all time single day record for tornadoes in Minnesota.
According to the count so far, there were a total of at least 27 (and likely more than 40) confirmed tornades in Minnesota June 17th, and the Grand Forks office has yet to confirm the actual number of touchdowns in their forecast area. This included the Wadena EF4 tornado and several others.
From The Twin Cities NWS:
HOWEVER...THE GRAND FORKS NATIONAL WEATHER SERVICE OFFICE HAS NOT
YET BEEN ABLE TO FINALIZE THEIR JUNE 17 TOTAL. THEY HAD MANY
TORNADOES IN THEIR AREA...INCLUDING TORNADOES RATED EF4 AT WADENA
THUS IT IS LIKELY THAT THE STATEWIDE TOTAL FOR JUNE 17
WILL BE IN THE 40S. THIS WILL EASILY ECLIPSE THE OLD RECORD OF 27
SET ON JUNE 16 1992.
It also looks like 2010, as reported here earlier this week, will end up as a record year for tornadoes in Minnesota. Again, here's the word from Twin Cities NWS.
THE SUMMER OF 2010...
WHILE JUNE 17 WILL CONTRIBUTE TO A HUGE NUMBER OF TORNADOES TO THE
STATEWIDE TALLY THIS YEAR...THERE HAVE BEEN MANY MORE TORNADO DAYS
SINCE THEN. IT HAS JUST BEEN WAY TOO BUSY TO TALLY ALL THE DAMAGE
SURVEYS... CORROBORATE SPOTTER REPORTS...VIEW ALL THE VIDEO AND
PHOTOS...AND CROSS CHECK DETAILS WITH RADAR...BUT IT LOOKS QUITE
LIKELY THAT 2010 WILL SET A RECORD FOR TORNADOES IN ONE YEAR. THAT
RECORD OF 74 WAS SET IN 2001.
It is still likely that we'll add to the number of tornadoes this year in Minnesota.
