This Hazardous Weather Outlook is for portions of central Iowa.

.DAY ONE...Today and tonight

Strong to potentially severe thunderstorms are forecast to develop
over western portions of Iowa late tonight and will spread
eastward during the overnight hours towards Wednesday morning.
Large hail and damaging winds look to be the primary threat, but
an isolated tornado or two cannot be completely ruled out. Locally
heavy rain is also possible.

.DAYS TWO THROUGH SEVEN...Wednesday through Monday

The aforementioned storms from late tonight into Wednesday
morning are likely to diminish in coverage and intensity across
eastern portions of Iowa after sunrise. A second round of strong
to severe storms look to develop by the afternoon over the central
to western Iowa. Large hail, damaging winds, and even a few
isolated tornadoes are possible.

Additional storms are forecast Thursday night into Friday and
again Sunday night into Monday. The severe probability remains
uncertain at this time.


Spotter activation is likely needed overnight tonight and again
Wednesday afternoon.
