AREAS AFFECTED...PORTIONS OF THE EASTERN DAKOTAS AND WESTERN
MINNESOTA
CONCERNING...TORNADO AND SEVERE THUNDERSTORM WATCHES 297...298...
VALID 100419Z - 100615Z
THE SEVERE WEATHER THREAT FOR TORNADO AND SEVERE THUNDERSTORM
WATCHES 297, 298 CONTINUES.
SUMMARY...DAMAGING WIND POTENTIAL CONTINUES WITHIN WW297 AND 298.
DISCUSSION...A SQUALL LINE CONTINUES EASTWARD ACROSS THE EASTERN
DAKOTAS INTO MINNESOTA, WITH 60-75 MPH GUSTS OBSERVED IN THE LAST
HOUR. TWO AREAS OF THIS LINE HAVE SHOWN AN INCREASE IN DAMAGING WIND
POTENTIAL OVER THE LAST HOUR.
THE LINE IN NORTHEASTERN SOUTH DAKOTA OUTSIDE OF ABERDEEN HAS
RECENTLY PRODUCED GUSTS TO 75-77 MPH, WITH A BOWING SEGMENT BECOMING
APPARENT. THIS AREA WILL BE A FOCUS OF SEVERE TO SIGNIFICANT SEVERE
WIND POTENTIAL (70-80 MPH) GIVEN THE FAVORABLY STRONG INSTABILITY
DOWNSTREAM.
FURTHER NORTH ACROSS NORTHERN NORTH DAKOTA, THE NORTHERN SEGMENT OF
THE SQUALL LINE HAS BECOME MORE PROGRESSIVE. THE VAD PROFILE FROM
MVX SHOWS AN INCREASE IN THE LOW-LEVEL JET, WITH 50-60 KT SOUTHERLY
FLOW IN THE LOWEST 1-2 KM. THIS AREA MAY ALSO DEVELOP AS A MORE
FAVORABLE CORRIDOR FOR SEVERE WIND POTENTIAL IN THE SHORT TERM GIVEN
THE INCREASE IN THE LLJ AND FAVORABLY WARM AND UNSTABLE ENVIRONMENT
DOWNSTREAM.
