For the 00Z TAFs, expect low cigs and areas of fog to continue across
the terminal sites through much of tonight, with gradually improving
conditions from north to south late tonight as drier air invades the
region. This will lead to VFR conditions at all TAF sites by around
sunrise Sunday and persisting through late Sunday afternoon.

Deeply saturated lower troposphere will be slow to cool overnight.
Threat for wintry precipitation appears to be greatly reduced with
light rain and fog as the prevailing weather types for tonight. Loss
of upslope flow over all but southeasternmost sections this evening
expected to limit precipitation amounts tonight. Shortwave trof
expected to arrive from the northwest, sweeping across the
Texas/Oklahoma Panhandles overnight. This feature will support the
potential for continued light precipitation mainly across east and
southeast sections, while also driving a weak cold front into the
area, causing clearing from the northwest overnight. There is a
very slight chance for isolated areas of brief light freezing rain to
develop just prior to the ending of the light rain. If this occurs,
do not expect any accumulations of ice.
Apart from some morning fog on Sunday, generally clear sky should
allow for respectable warmup on Sunday and especially Monday, when
southwest and south winds resume ahead of deepening lee trof.
Cold front Monday night expected to knock Tuesday high temperatures
back to about 10 degrees Fahrenheit below normal. Arctic cold front
arrives late Tuesday night and Wednesday morning, with single-digit
or sub-zero wind chill indices forecast for roughly the northwest
half of the forecast area. Light snow will also be possible Tuesday
night and Wednesday, especially across north-central and northeast
sections, where one to two inches look to be possible. Dry forecast
Wednesday night and beyond as post-frontal airmass expected to be
Cold conditions continue through Thursday, when highs in the lower-
to mid-30s are expected. Warmup expected for Friday and Saturday.
