.DISCUSSION...
Issued at 122 PM CST THU DEC 25 2014

After a mild and breezy day temperatures will remain above normal
tonight and again tomorrow ahead of an approaching trough and
attendant cold front moving in from the west. Very late
tonight/early morning Friday isentropic ascent ahead of the trough
should foster the rapid development of cloud cover leading to spotty
DZ/-SHRA by the afternoon. Tomorrow night as the cold front moves in
from the northwest POPS increase for some light rain showers that
will eventually mix with light snow. QPF amounts for the CWA are in
the 0.08-0.15 inch range so what snow does develop is not expected to
amount to much... a dusting or so. The system quickly clears from
west to east Saturday morning with partial clearing and near normal
high temps in the 30s.

The CWA remains quiet on Sunday before much colder air begins to
advect into the region on Monday. At this time the NWP consensus
maintains very slight chance POPS behind a cold frontal passage
Monday evening into early Tuesday morning amounting to perhaps a
dusting to quarter inch of fluffy snow.  The northwest portion of
the CWA has the best chance for seeing light snow.  Otherwise
Tuesday through the rest of the periods should be dry with
temperatures well below normal.

.AVIATION...(For the 18Z TAFS through 18Z Friday Afternoon)
Issued at 1139 AM CST THU DEC 25 2014

VFR conditions will persist through much of the period. Tight
pressure gradient across the region will allow higher momentum winds
to transfer to the surface resulting in gusty surface winds
continuing through the daylight hours. The gradient will relax and
winds decreasing with loss of diurnal heating. Mid and high Clouds
will increase as cold front approaches the terminals by 12Z. MVFR
ceilings will begin to build in by late in the prevailing TAF period
and will be dependent on the timing of the frontal passage.
