Areas affected...Parts of northeastern Minnesota
Concerning...Severe Thunderstorm Watch 626...
Valid 252133Z - 252230Z
The severe weather threat for Severe Thunderstorm Watch 626
continues.
SUMMARY...A highly localized favorable corridor for supercell
intensification and a brief tornado and damaging wind gusts may
persist for another hour or so.
DISCUSSION...A weak, semi-discrete supercell structure is tracking
eastward across parts of northeastern MN, with access to
warm/unstable inflow to its southeast. Trailing cells and associated
outflow are approaching this storm from the west. This could support
a constructive cell interaction and brief intensification of the
supercell as it continues eastward for the next 30 min to an hour --
before being undercut by the outflow. This could support a locally
favorable risk for a brief tornado and damaging wind gusts.
