Probability of Watch Issuance...95 percent
SUMMARY...Scattered thunderstorms are expected to develop along a
cold front through this evening. Large hail up to 1.75-2.50" in
diameter and damaging wind gusts near 60-70 mph will be possible.
DISCUSSION...Latest satellite and radar imagery suggest thunderstorm development will continue to occur along a cold front extending
northeast to southwest across portions of far northwestern MN and
eastern ND. A moderate to extreme instability axis extends along and
ahead of this cold front, where temperatures have climbed into the
upper 80s, and dewpoints in the mid 60s to low 70s exist beneath
steep mid-level lapse rates. VAD profiles and objective analysis
across this region indicate sufficient deep layer effective shear
(40-55 kt) is already in place. Storm organization and a few
supercells appear likely along this axis through this evening. Large
hail will initially be possible with the more discrete thunderstorms
that develop, before cell mergers occur with an accompanying
damaging wind threat later this evening as instability wanes. A
severe thunderstorm watch will be needed soon.
