Areas affected...Southwest into parts of central Iowa

Concerning...Tornado Watch 191...

Valid 070216Z - 070415Z

The severe weather threat for Tornado Watch 191 continues.

SUMMARY...An increase in damaging wind and QLCS tornado threat can
be expected in southwest Iowa over the next 1-2 hours. Some risk
will continue into central Iowa later this evening.

DISCUSSION...Numerous wind damage reports as well as several
observed/estimated severe gusts have occurred in
southeast/east-central Nebraska. Moisture advection continues to
maintain low 60s F dewpoints into southwest Iowa. Thought buoyancy
will be limited to some extent, convection should remain
surface-based for another few hours with additional support from the
shortwave pivoting through the mid-Missouri Valley. The KDMX VAD
shows 0-1 km SRH of over 400 m2/s2. Several QLCS
circulations/tornadoes are possible along with a continued damaging
wind threat. Given the forcing from the low-level jet and the
upper-level shortwave, this activity seems likely to at least reach
parts of central Iowa. Beyond 06Z, the low-level jet is forecast to
weaken which could begin to limit the intensity of the line.
