.SHORT TERM...(Today through Monday)
Issued at 135 AM CST Sun Dec 15 2019

Looks like the NAM has decided to join the plethora of other models
with taking an upper level shortwave trough  out of the southern
Rockies tonight, sliding it east across IA/IL Sun night/Mon. Light
pcpn results, but looks to stay just south of the local area
(previous NAM runs suggested snow as far north as I-90).

Temperatures going to stay on the coldside into the early part of
the new work week as northwest flow a loft influences the region.
Highs in the teens/20s with single digits above/below normal

.LONG TERM...(Tuesday through Saturday)
Issued at 135 AM CST Sun Dec 15 2019

Quiet with little in the way of pcpn chances on the horizon.

The weekend cold will persist for the early part of the new work
week as an upper level trough/northwest flow continues to pull
Canadian air southward. The GFS and EC remain in good agreement with
upper level short/long wave ridging to build in for the later half
of the week, with moderating to mild temperatures resulting. The
mild temps could stick around into Christmas - which could do away
with the current snow cover (putting at hit on a white Christmas).
The CPC 8-14 day outlook suggests above normal temps through the end
of the month.


.AVIATION...(For the 06Z TAFS through 06Z Sunday night)
Issued at 1032 PM CST Sat Dec 14 2019

VFR conditions have returned to LSE and RST and will stick around
the next 24 hours, with some passing mid and/or high clouds at
times. Winds from the northwest up to 10 knots the rest of tonight
will become lighter from a more southerly direction later Sunday.
By late Sunday afternoon and evening, some thicker clouds in the 5-
8k ft range are expected to slide in from the west.
