November Weather Surprise

To say that the weather over the past couple/few days has been interesting is a bit of an understatement.

A weekend of two seasons

The National Weather Service now confirms two tornadoes touched down in the Twin Cities late Saturday night.  Both were EF-0 tornadoes, the weakest on the scale.

Here are some photos of the damage from the NWS office.   Click here for more.

One of the tornadoes was in Burnsville.   Here’s a look at the 2.6 mile path. The tornado was  about 100 yards wide or the width of a football field.

The other tornado was just east of the Minneapolis St. Paul International Airport near Mendota Heights and north of Eagan. It was also an EF-0 tornado but slightly weaker and smaller even than the Burnsville tornado.

Tornadoes in November are pretty rare in Minnesota. And the fact the Saturday’s tornadoes were late at night goes to show the strength of this cold front.

There’s only one official tornado report in Minnesota since 1950.  It was back on November 1st, 2000 in Kandiyohi County west of the Twin Cities.

There is evidene of two other tornadoes in November prior to 1950.  One was November 2nd, 1938. The other November 16th, 1931.

The November 16th tornado is believed to be the latest tornado of the season in Minnesota. Saturday’s tornadoes would be the second and third latest tornadoes in Minnesota state history.

Minnesota averages about 27 tornadoes a year. More than a third of those or 37 percent typically occur in June.

Minnesota may not see too many tornadoes in November, but in other states tornadoes are more common especially in the South.
