...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS PORTIONS OF THE
MIDWEST AND CENTRAL PLAINS...
...SUMMARY...
Severe thunderstorms are expected this evening across the Dakotas,
Upper Midwest and Middle Missouri Valley, including damaging winds,
large hail and a few tornadoes.
...Northern Plains and Midwest...
Thunderstorm activity has initiated across eastern Nebraska near the
cold front this evening, with additional areas of towering cu noted
into northern Kansas. As the low-level jet strengthens and ascent
increases with the approaching wave, it is likely additional
thunderstorm development will occur into the evening. Guidance
suggests that a mix of supercells and multi-cell clusters will
emerge and spread east northeastward into far southeastern
SD/northwestern IA and western MN. Strong to extreme instability and
steep lapse rates downstream will likely support potential for
damaging wind, with some significant gusts 75+ mph possible. Large
to very large hail will also be possible where supercells can
maintain semi-discrete mode. An upgrade to Enhanced was made with
this update to account for this potential. See MCD#1386 for
additional information on the short term severe potential.
Further north across eastern North Dakota into western/central
Minnesota near the surface low/warm front interface, potential will
continue for supercells capable of all hazards including large hail,
damaging wind, and strong tornadoes. See MCD#1387 for more
information.
...Southwest Texas to the Texas/Oklahoma Panhandles...
Thunderstorm activity continues across southwestern Texas into the
Texas/Oklahoma Panhandles near the dryline. Very warm temperatures
and dry mixed boundary layer conditions will continue to pose some
potential for damaging winds until sunset this evening.
...Georgia into northern Florida Peninsula...
A cluster of thunderstorms continues to move southwestward across
southern/central Georgia this evening. Ahead of this cluster, hot
and moderately unstable conditions will continue to pose potential
for water loaded downdrafts that my produce strong to severe winds.
