Areas affected...Parts of eastern SD into west-central/southwest MN
Concerning...Tornado Watch 271...
Valid 040137Z - 040300Z
The severe weather threat for Tornado Watch 271 continues.
SUMMARY...Some threat for hail, damaging wind, and possibly a
tornado may continue through the evening.
DISCUSSION...A small storm cluster with a history of producing
severe gusts across far northeast SD is approaching the SD/ND/MN
border intersection as of 0130 UTC. Low-level moisture and buoyancy
weaken with eastward extent, which will tend to limit the longevity
of the severe threat with this cluster into west-central MN.
However, given the current organization of this cluster, some threat
for damaging wind and isolated hail could spread east of WW 271
before a definitive weakening trend occurs. Given the expected
weakening trend with time, the need for downstream watch issuance is uncertain.=20=20
Farther south, relatively disorganized convection is ongoing across east-central SD. The environment across this area remains somewhat
favorable, with moderate buoyancy and sufficient deep-layer shear
for organized convection. The ongoing convection could produce
sporadic hail and isolated strong/damaging gusts. It remains
possible that a supercell or two could evolve across this area
through dusk, which would result in an increasing hail threat, along
with some tornado potential.
