1130 PM CST Wed Jan 17 2018

.SHORT TERM...(This evening through Thursday)
Issued at 220 PM CST Wed Jan 17 2018

While remaining cold tonight there will be an improvement as
temperatures should stay above zero with the help of a developing
southwesterly wind. This will lead varying temperatures from hills
to valleys with the coldest readings in the valleys.

Southwesterly winds will increase Thursday as surface high
pressure settles to the southeast and low pressure takes shape
over the high plains. This will help to push temperatures upward
but the warming trend will be initially muted due to the existing
snow cover.

.LONG TERM...(Thursday Night through Wednesday)
Issued at 220 PM CST Wed Jan 17 2018

The warming trend will persist late week into the weekend as
southerly winds persist and even increase. A return of low level
moisture will begin as early as Friday night into Saturday
resulting in increasing cloud cover and perhaps some drizzle.
Temperatures will warm into the lower and middle 50s on Saturday.

Meanwhile a deep low pressure trough will push into the western
U.S. and across the Rockies this weekend resulting a deep
southwesterly flow. As deepening surface low pressure tracks from
the central Plains toward the Midwest and associated cold front
swings eastward expect showers and thunderstorms to develop from
west to east on Sunday. Instability looks to be marginal but
favorable shear profiles and synoptic scale setup could support
stronger storms. Forecast confidence on the details is low at this


.AVIATION...(For the 06Z TAFS through 06Z Thursday night)
Issued at 1119 PM CST Wed Jan 17 2018

VFR are expected through the forecast period. Surface high
pressure will remain over the Lower Mississippi Valley through the
period as an upper level ridge begins to build into the Northern

Winds will begin to veer and gradually increase late tonight into
the day on Thursday. Will likely see gusts over 20 kts over
western portions of the area from mid morning through sunset.
