Short term...(tonight through thursday)
issued at 325 PM CDT Tuesday Jul 28 2015

A cold front is slowly making its way through the region this
afternoon. Conditions ahead of the front remain hot and humid...with
heat indices near 100 in southeast Nebraska and around 108 in
southwest Iowa. Behind the front temperatures remain in the low 80s
and middle 70s with dewpoints mainly in the 50s and 60s. Showers and
thunderstorms will continue to redevelop across southeast Nebraska
and southwest Iowa this evening. A few storms could become strong to
severe across southeastern Nebraska and southwest Iowa tonight where
a remnant outflow boundary intersects the cold front. Storms in this
region will be aided by an axis of 2500+ j/kg of instability under
an eroding cap and around 40kts of effective shear. Heavy rain will
also be possible with evening storms as precipitable waters are currently in the
1.9 to 1.8 range. Storms should be out of the region by early
Wednesday morning...possibly sooner if a sufficient cold pool is
able to develop...eventually making their way into Kansas and

Cooler and drier air will then encompass the forecast area
tonight and throughout the day Wednesday with highs in the middle 80s
and clear skies overhead. Flow will take on a more southerly
component Thursday bringing slightly warmer air to the region.
