Areas affected…Far eastern South Dakota into Central/Southwest
Minnesota
Concerning…Severe Thunderstorm Watch 649…
Valid 261943Z – 262145Z
The severe weather threat for Severe Thunderstorm Watch 649
continues.
SUMMARY…Potential for large/very-large (2+ inches) hail and severe
winds (some 75+ mph) will increase this afternoon into the evening,
especially for parts of central/southern Minnesota.
DISCUSSION…A storm within the buoyancy gradient has increased in
intensity over the last 30 minutes. Additional development appears
likely to its immediate south-southwest. Potential for large and
severe winds are expected to increase this afternoon. Of additional
concern are towering cumulus starting to develop in west-central
Minnesota and far eastern South Dakota. Short-term guidance from the
HRRR and the latest MPAS runs suggest that one or both of these
areas could see storms develop within the next 1-3 hours. These
storms are in a more favorable thermodynamic environment than storms
farther north. Large to very-large (2+ inches) hail and severe winds
(some 75+ mph) would be possible. The exact evolution of these
storms remains a point of uncertainty. Most guidance suggests that
storms could congeal into an MCS where severe winds would become a
greater threat as activity moves east.
