DISCUSSION...
Please see the 00Z aviation discussion below.

AVIATION...
VFR will apply through the forecast period. Very light winds are
expected after sunset this evening. Skies will also clear. Winds
will increase slightly by late Memorial Day mainly from the SW for
most terminals.

PREV DISCUSSION... /issued 233 PM CDT Sun May 28 2017/

DISCUSSION...
Slightly cooler and drier air has overspread the area today.
Another rather pleasant day is expected on Monday as weak surface
high remains over the area.

As we go into Monday night and Tuesday, could see a few showers
across the north as a weak surface front approaches as large upper
low spins across Great Lakes region. This keeps us on the edge of
northwest flow for the first part of the upcoming week.

Another weak surface boundary will approach northern Oklahoma
Wednesday, keeping slightly better chances for rain across the
north. At this same time, an upper trough that takes shape over
the northern Baja begins to shift northeast toward the southern
Plains. This looks to bring a better chance of rain to the area
Thursday into Friday.

Models diverge in solutions quite a bit by next weekend, lowering
confidence in that timeframe. ECMWF shows larger ridge developing
across central U.S., while GFS is slower with the development of
the ridge. GFS brings a couple of shortwave troughs and associated
rain/thunder through the area next weekend. Will keep some low
pops into next weekend for consistency sake for now.
