Areas affected...portions of northern Missouri and southern Iowa

Concerning...Tornado Watch 303...305...

Valid 102127Z - 102230Z

The severe weather threat for Tornado Watch 303, 305 continues.

SUMMARY...Multiple tornadic supercells are ongoing across northern
MO and southern IA. The environment remains very favorable for
tornadoes, some of which could be strong to intense.

DISCUSSION...Recent radar imagery and storm reports show several
tornadic supercells are ongoing across northern MO and southern IA
in Tornado Watches 303 and 305. The environment downstream of these
storms is modifying in the wake of an earlier MCS and remains highly
conducive for supercells and tornadoes. Backed low-level flow and
deep veering along the modified boundary is supporting STP values of
3-4. A recent, likely strong tornado (VROT 50+ kt and TDS > 10k ft),
over Putnam County, MO confirms the environment is supportive of
strong to intense tornadoes and will likely remain so into the early
evening.
