Area forecast discussion 
National Weather Service Norman OK
540 am CST Friday Dec 26 2014

the 12z aviation discussion follows....


a cold front located near kavk-kgag at 11z will move slowly southeast
today and tonight. Wind shifts near the front at some sites will
be far more complicated than the single shift indicated in the
tafs...perhaps a couple of hours of variable directions and
speeds before switching fully to N/NW. Ceilings in the MVFR
category will follow the front...and also precede it at some sites
as warm and humid air is drawn north ahead of the storm system. Expect
areas of -ra...-rasn...and -sn tonight and early Saturday. A few
patches of very light precipitation may also occur during the day
today...with minimal impacts on aviation. Areas of br or fog will
be possible in southeast OK early Saturday...but should stay east of


Previous discussion... /issued 347 am CST Friday Dec 26 2014/

a cold front now over extreme northwest Oklahoma will move slowly
southeast today...bringing colder weather behind it. There may be
a little snow in the northwest...and rain elsewhere. Rain ahead of
the front will be mainly light warm-air advection rain...perhaps
drizzle. None of the precipitation is expected to amount to much.

Tonight...the front will continue to trudge southeast...passing
through Oklahoma City and vicinity early this evening...and
finally moving southeast of our forecast area around sunrise on
Saturday. Light Post-frontal rain or snow will bring a chance of
light snow accumulations to much of the northwest half of
Oklahoma...including Oklahoma City. At this time...amounts look
like they will be around half an inch or less. Of course...if snow
bands form and move slowly...a few stripes of more significant
snowfall will occur. In central Oklahoma...snow will probably melt
rather than accumulate. Travel problems are unlikely...but cannot
be completely ruled out...especially in far northwest Oklahoma.

Little or no precipitation is expected from Saturday night through
Thursday. even colder airmass is expected to begin
affecting Oklahoma early next week...probably during the day on
Monday. The cold weather is forecast to remain with US at least
through the first week of January.
