0Z TAF discussion below.
Some low clouds and reduced visibilities will be possible tonight,
with the best chance for these conditions in parts of SW OK and W
N TX. There is some uncertainty as to how low visibilities will
drop and how low the ceilings will develop later this evening.
Ceilings and visibilities will improve overnight into Tuesday as a
cold front moves across the area bringing drier air and gusty N
winds to the region.
.PREV DISCUSSION... /issued 320 PM CST Mon Dec 5 2016/
A mid-level low/trough will continue northeast across southern
and eastern Texas this afternoon and evening. As a result,
scattered light rain showers will be possible across mainly south
central and southeast Oklahoma through the mid evening.
Farther north, broken low clouds should continue to decrease
some through the early evening. However, some model soundings
suggest very low clouds and some fog may develop this evening as
winds decrease ahead of a cold front. Not overly confident in
fog/very low clouds, but enough potential to mention. Some of the
fog may develop by 9-10 pm.
As the initial cold air arrives tonight and early Tuesday,
any dense fog will dissipate, but low clouds may linger for
several hours behind the cold front.
A few stations in far northwest Canada and eastern Alaska are
reporting temperatures around minus 35 to 40. As another trough
moves across the northern Rockies on Tuesday, some of this air
will move quickly southward into the northern part of the country.
This airmass will reach northern Oklahoma sometime Wednesday
Rather strong northerly winds are expected to develop as the cold
air moves southward. This will produce very cold wind chill values
Wednesday night into part of the day Thursday.
At this time, it appears that snow chances will be very low.
By late Thursday into Friday morning, winds should be light with
a rather clear sky. By sunrise Friday, most places will cool into
at least the teens with some single digits possible.
Warmer and dry weather can be expected Friday through at least
