.AVIATION...
Still dealing with mostly AC deck near and to the south of our
I-20 terminal airports this evening and even some 3kft ceilings in
the vicinity of the MLU airport but these ceilings should continue
to shift southward as we go through the overnight hours. While we
cannot rule out a brief MVFR ceiling at the MLU airport over the
next couple hours, VFR conditions should prevail through the next
24 hours.

Mostly north winds near 10kts overnight should remain north to
northeast near 5 to 10 kts across the region for Wednesday.

.PREV DISCUSSION... /issued 409 PM CST Tue Jan 16 2018/

DISCUSSION...
Our much anticipated winter weather snowfall event has wrapped up
late this afternoon with cloud cover still in place south of I-30.
The final winter weather advisory across our southern sections has
been cancelled early due the snowfall exiting our southernmost CWA.
Our remaining hazard products for tonight include an areawide Wind
Chill Advisory and a Hard Freeze Warning as temperatures plummet
immediately after sunset. The hazard products both take effect at
8 PM tonight and continue through 10 AM Wednesday. Although snow
has ended, very little if any melting occurred this afternoon so
expect most secondary roads to remain troublesome overnight along
with any refreezing of lingering moisture on bridges and overpasses
where black ice may develop. These travel concerns will carry over
into Wednesday as well with temperatures still struggling to get
above freezing. Therefore, road conditions overall may not fully
improve until Thursday when temperatures are expected to climb
into the lower to mid 40s areawide.

This warming trend will allow for a mid January thaw by Friday
and through the weekend with 50s for highs on Friday and 60s
during the weekend with lower 70s not out of the question. The
chance of rain will return to the forecast by Friday night over
our western half and expand farther east on Saturday as scattered
showers develop ahead of an approaching cold front. This Pacific
front will not bring a considerable air mass change, but expect
widespread showers and isolated thunderstorms on Sunday through
Sunday night with frontal passage. A dry and mild forecast will
follow suit for early next week with temperatures running very
near or just slightly above seasonal averages for late January.
