Temperatures this afternoon have reached well into the mid to upper
90s across the area with heat indices well into the century mark.
Noticeable changes are on the way however with much cooler
temperatures in store for tomorrow and into next week. This is in
thanks to a well-advertised pattern change, starting with a frontal
boundary traversing the forecast area tonight.

Current obs indicate the boundary is knocking on our doorstep, laid
out across southeastern NE into west-central IA. Ahead of the front,
some showers and thunderstorms have developed and will continue to
track toward and into NW MO as the afternoon progresses. Nocturnal
LLJ will crank up again tonight and with decent moisture availability
as well as the front to work with, storm chances will be on the
increase this evening into the overnight hours. With marginal shear
values, the primary concern tonight will be the potential for
flooding issues should storms containing moderate to heavy rain train
over the same areas and/or have slow storm motions as the front slows
down in its southward trek. However, gusty winds in some stronger
storms will be possible as well. This nocturnal pattern looks to
repeat throughout the weekend with the question being where the
concentration/cluster of storms will develop. The models have been
struggling to agree on the finer details of these sorts of situations
thus far this summer and this event is no exception. Saturday night
looks particularly possible for a bust scenario across this forecast
area should the bulk of the precip go north into NE and IA with some
models indicating as such. Of course, further out in the forecast
period, the confidence in the details drops as the models diverge on
solutions, although a period of unsettled weather looks to continue
well into next week.

Issued at 634 PM CDT THU AUG 4 2016

VFR conditions are expected for the next several hours as most
thunderstorm activity focuses from southeast NE through central IA
and gradually dissipates after sunset. An additional round of storms
may develop and head eastward into the terminals early Friday AM;
however the probability was not high enough for more than a VCTS
mention for a few hours around sunrise. Otherwise, cigs and vsbys
will be VFR; while winds will veer to the southwest this evening,
become light and variable as a cold front pushes through early
Friday, then eventually increase out of the north northeast.
