DISCUSSION...
For the immediate short term, radar imagery and latest surface
observations indicate and area of snow flurries or brief period
of light snow moving southeast across western and central sections
of the fcst area in association with passage of an upper level
positively tilted shortwave trof. The precipitation should end by
around sunset. Surface winds will also diminish by early this
evening, and will allow the current Wind Advisory to expire at 6
PM CST today.

Short and medium range models continue to suggest an overall
pattern that features an upper level ridge of high pressure over
the western states with an upper level trof situated across the
eastern states. Our forecast area is in predominant northwest flow
aloft, which is generally dry this time of year. This particular
pattern is progged to persist into early next week. Both short and
medium range models are in reasonable agreement through early
next week and were accepted.

For tonight, the combination of clearing skies, invasion of drier
air, and diminishing winds will result in lows falling into the
teens to lower 20s. On Wednesday, plenty of sunshine and a return
of light west winds should help max temperatures warm to near
normal values for late January.

The next cold front and associated minor upper level shortwave
trof embedded in the northwest flow aloft pattern will move across
the OK and TX Panhandles late Wednesday night, with cooler
temperatures in store on Thursday. A near repeat performance is
then anticipated for late Friday night and early Saturday with
passage of another cold front and corresponding slightly cooler
temperatures for Saturday.

A brief warming trend is expected on Sunday, followed by yet
another cold front early Monday, which will set the stage for
below normal temperatures later Monday into Tuesday. Retained low
pops offered by superblend consensus models for northwest sections
of the fcst area on Monday as a slightly stronger upper level
shortwave trof traverses the srn high plains.
