.SHORT TERM...(This evening through Tuesday)
Issued at 217 PM CDT SUN AUG 23 2015

Unseasonably cool high pressure for mid/late August will build
into the Plains in the short term. Will be flirting with record
lows Monday/Tuesday nights. Some locations up along the I-64
corridor may even dip into the upper 40s, with 50 to 55 most
other areas. Afternoons will be quite pleasant with full sunshine
and highs in the upper 70s to near 80, more typical of the late
September/early October.

.LONG TERM...(Tuesday night through Sunday)
Issued at 217 PM CDT SUN AUG 23 2015

We will start out the midweek with northwest flow aloft...as an
upper low churns over eastern Canada and an upper level high sits
out over eastern CO/NM and west TX. High pressure sliding east from
the upper Mississippi valley into the northeast U.S. will keep
conditions dry and pleasant across the area Wednesday into Friday.
North to northeast flow at the sfc through the end of the week will
keep temperatures below normal with highs in the upper 70s to lower
80s, and lows in the middle 50s to around 60 degrees. We will gain a
degree or two each day through the weekend.

Models are picking up on a disturbance in the NW flow...moving
across IA on Friday afternoon. This disturbance moves southeast into
our area on Saturday. However, models differ on what to do with this
feature and how much moisture is associated with it. We will leave
it as a signal to watch for, but for now, prefer to leave have
minimal POPs for Saturday night/Sunday. Wouldn`t be surprised to see
further shifts fine tune things and raise them at some point for
some part of the weekend.

.AVIATION...
Issued at 545 PM CDT SUN AUG 23 2015

A late day pre frontal wind shift is/will be followe by the robust
cold fropa in the first 3 hours of the issuance period. Winds will
shift from WSW to NW during this initial time period and may be
accompanied by scattered MVFR decks and low VFR cigs at times.
After fropa...skies will clear and light nwlys will prevail and
should minimize prevalance/fog esp as drier air works in/down the
column (though we`ll monitor). Tmrw should be high pressure driven
with nwly flow regime and moclear sky...save for high based cu
that may develop during the pm hours/esp for northeastern
terminals KEVV/KOWB.
