Weather Summary for Iowa

516 PM CDT Thu Aug 18 2016
Multiple storms bordered Iowa to the north and east this
afternoon, but conditions in the state were dry through the 5pm
hour. Highs this afternoon topped out in the upper 80s to low 90s
with heat indices in the upper 90s to low 100s. Skies were partly
cloudy to mostly clear with a south to southwest wind of 5 to 10
mph with a few gusts up to 20 mph.
The aforementioned storm cell over far south central Minnesota may
spread southeast and affect northeast Iowa this afternoon and
evening, but otherwise look for a mostly clear and muggy evening
over Iowa. A seasonably strong cold front will push through Iowa
Friday, bringing with it widespread thunderstorms, especially
during the afternoon through the overnight. Damaging winds appear
to be the main severe threat, along with small hail. Localized
heavy rainfall approaching 2 inches or more will be possible.
Temperatures will cool substantially behind the front, with highs
in the low to mid 70s for the weekend. A light warm up will ensue
early next week with the next good opportunity for widespread
rainfall coming late Tuesday into Wednesday.
