Areas affected...Far Eastern South Dakota...South-central Minnesota

Concerning...Severe Thunderstorm Watch 548...

Valid 280019Z - 280215Z

The severe weather threat for Severe Thunderstorm Watch 548
continues.

SUMMARY...The severe threat, associated with a convective complex
from eastern South Dakota into south-central Minnesota, is expected
to gradually shift eastward and southward across southern Minnesota
over the next few hours. Although a brief tornado will be possible,
large hail and wind damage are expected to be the primary threats. A
new weather watch may need to be considered to the east of the
current watch.

DISCUSSION...Mosaic radar imagery currently shows an east-to-west
cluster of strong to severe storms from near Watertown, South Dakota
eastward to just west of Minneapolis, Minnesota. This relatively
large cluster is located along a strong gradient of instability,
which extends southeastward into northern Iowa. These storms are
forecast to develop southeastward along this gradient over the next
few hours. The eastern edge of the complex may also affect parts of
far southeastern Minnesota and far western Wisconsin. Moderate to
strong instability, along with 0-6 km in the 30 to 45 knot range
according to the RAP and 00Z Minneapolis sounding, should support a
continued severe threat. Supercells with isolated large hail will be
possible. Wind damage will be likely within and near the faster
moving bowing line segments.
