Areas affected...Central/Eastern Iowa

Concerning...Tornado Watch 115...

Valid 050210Z - 050315Z

The severe weather threat for Tornado Watch 115 continues.

SUMMARY...Severe threat will continue beyond watch expiration. New
Severe Thunderstorm Watch will likely be issued by 03z.

DISCUSSION...Warm-advection thunderstorms have generally lifted
north of ww115 as the warm front advances north ahead of the
approaching short wave. Primary concern for convection the next
several hours will be along the advancing cold front where the
convective mode is becoming linear dominant. While isolated
supercells will continue along the line, and perhaps ahead of the
evolving squall line, it appears the main risks will now be
hail/wind. New ww will likely be issued by 03z (before expiration)
to account for this threat.
