National Weather Service Omaha/Valley NE
1151 PM CDT THU MAY 26 2016

.SHORT TERM...(tonight through Sunday)
Issued at 220 PM CDT Thu May 26 2016

Warm front was located across northeast Kansas at 19z with a large
area of convection blooming on either side of the front. Periods
of thunderstorms are expected through most of the period as upper
trough over the southern Rockies this afternoon lifts across the
plains region toward the upper Midwest through Saturday. There
looks to be a brief break in the stormy pattern late Saturday
night into Sunday behind the trough but additional storms return
by Monday.

Flash flood watch will cover parts of southeast Nebraska and
southwest Iowa near the warm front through tonight with potential
for several rounds of thunderstorms and heavy rain.

.LONG TERM...(Sunday night through Thursday)
Issued at 220 PM CDT Thu May 26 2016

Upper pattern becomes more amplified again in the extended period
with more storm chances into at least Wednesday although ECMWF is
a bit quicker with drier conditions by Tuesday night compared to
the GFS.

.AVIATION...(06Z TAFS for KOMA...KLNK...KOFK through 06Z Saturday)
Issued at 1145 PM CDT Thu May 26 2016

Wake-low-induced gusty winds ongoing at KOMA should subside within
the next couple of hours as the surface pressure gradient relaxes.
A band of mainly showers over central Nebraska should gradually
overspread the TAF sites overnight in response to the
northeastward progression of an MCV currently near KLXN. Some MVFR
ceilings may develop late tonight into early Friday on the
backside of this precipitation band. A break in the precipitation
is expected generally between 12 and 18z Friday before shower and
thunderstorm chances again increase ahead of the mid-level trough
pivoting northeast across the central Plains.
