.SHORT TERM /THROUGH SATURDAY/...
Issued at 240 PM CDT Fri Jul 19 2024

Scattered to broken high-based cumulus clouds will quickly
dissipate by sunset, leaving a clear night with calm winds. Lows
will bottom out mainly in the upper 50s.

On Saturday, weak low pressure, surface and aloft, will drift
from SD to nw IA. Increasing mid/high clouds can be expected but
the forecast soundings indicate very dry low levels. Therefore,
not expecting any rain reaching the ground (Sprinkles perhaps?).
Highs will be in the upper 70s at most locations, along with
tolerable humidity levels (dewpoints in the lower 60s).

.LONG TERM /SATURDAY NIGHT THROUGH FRIDAY/...
Issued at 240 PM CDT Fri Jul 19 2024

Split flow with a cut-off low will slowly meander across the
Corn Belt. Shear will be weak and lack of Gulf moisture should
keep severe weather and heavy rainfall in check. There looks to
be a daily chance for scattered showers and a few thunderstorms,
mainly in the afternoon and evening hours. Pops from Sunday
through Wednesday are only in the 20-40 percent range each day.
Significant rainfall is not expected. Daily highs should be in
the lower 80s with lows in the lower to mid 60s, which is near
normal for mid July.
