NARRATIVE: A BRIEF EF-0 TORNADO SPUN UP NEAR SKYLINE DRIVE EAST OF HWY 13 AND TRACKED NNE TO THE LOST SPUR GOLF COURSE JUST SOUTH OF I-494. NUMEROUS TREES WERE BLOWN DOWN AND EXHIBITED A CONVERGENT DAMAGE PATTERN. SOME TREES FELL ONTO HOUSES AND POWER LINES. OTHERWISE...LITTLE STRUCTURAL DAMAGE. ESTIMATED WINDS 75 MPH.


IN ADDITION TO THE WEAK TORNADOES...SPORADIC STRAIGHT LINE WIND DAMAGE OCCURRED BETWEEN THE TWO TORNADO TRACKS AND FURTHER NORTHEAST INTO WEST ST PAUL. STRAIGHT LINE TREE DAMAGE WAS MOST CONCENTRATED IN WEST ST PAUL WHERE WINDS WERE ESTIMATED AT ABOUT 75 MPH. ST PAUL DOWNTOWN HOLMAN FIELD REPORTED A WIND GUST OF 70 MPH.

TORNADOES IN NOVEMBER ARE EXCEEDINGLY RARE FOR MINNESOTA. SINCE THE MOST COMPLETE TORNADO RECORD DATABASE STARTED IN 1950...ONLY ONE TORNADO OCCURRED IN NOVEMBER...11/1/2000. HOWEVER...THERE IS EVIDENCE OF TWO OTHERS PRIOR TO 1950...ONE ON 11/2/1938 AND ANOTHER ON 11/16/1931.

THE TORNADOES WERE WEAK AND BRIEF DUE TO A LESS THAN FAVORABLE ENVIRONMENT FOR TORNADO FORMATION. WHILE WIND SHEAR WAS STRONG... INSTABILITY WAS VERY LOW MAKING THIS EVENT RATHER ANOMALOUS. WIND SHEAR AND INSTABILITY ARE KEY INGREDIENTS FOR TORNADOES AND SEVERE WEATHER.

THIS DATA IS CONSIDERED PRELIMINARY AND IS SUBJECT TO CHANGE BASED ON ANY NEW INFORMATION GATHERED.
