.SHORT TERM...(Tonight through Friday)
Issued at 200 PM CDT Mon Oct 16 2017

Models in lock-step with zonal/ridging in the upper level flow into
Friday. A couple weak ripples move through in the middle part of the
week, but moisture is lacking and not expecting a pcpn threat.
Mostly, its about a return to above normal temperatures. NAEFS 850
mb temp anomolies continue to hover around +1 to +2 through Friday.
Looking for highs from the mid 60s to mid 70s, with Friday still
looking like it could be the warmest of the bunch. Overall, a nice
break from the cool, wet conditions of the past many days.

.LONG TERM...(Saturday through Monday)
Issued at 200 PM CDT Mon Oct 16 2017

Both the GFS and EC take a trough from the west coast due east,
sliding it through the Upper Mississippi River Valley Sat night/Sun.
Its associated cold front leads the system into the region with
decent low level moisture return and a little instabilty to play
with it. Both models develop convection along and behind the front,
focusing on Sat night-Sun morning for the higher rain threat. The
GFS is suggestive of a few ripples working their way out of the mean
trough Fri night-Sat, which could result in pockets of
showers/storms. EC more subduded with these chances.


.AVIATION...(For the 18Z TAFS through 18Z Tuesday afternoon)
Issued at 1221 PM CDT Mon Oct 16 2017

Main concern will be some windshear this evening/overnight at KLSE
and KRST. Expect southwest winds around 40kt within 1500-2000ft agl,
tapering off after 08-10z. Otherwise, high pressure will be in
control through the period with VFR conditions.
