National Weather Service Norman OK
526 am CST Thursday Dec 18 2014
please see the 12z aviation discussion below.
confidence is moderate to high that LIFR will apply at most
terminals through the entire period due to low ceilings. Some
improvement will be possible at wwr/gag...and perhaps Special Weather Statement...where
ceilings may lift to around 015 but these will drop again later
tonight. Expect light east to NE winds around 5 to 10 knots.
Previous discussion... /issued 441 am CST Thursday Dec 18 2014/
significant precipitation has ended across the region. There is still a
possibility of very light rain/snow near the Kansas/OK border early
this morning...but amounts will remain very low and impacts to
travel will not be a problem. Elsewhere...drizzle and fog
continue to impact the area. Expect this to continue most the
day...which will keep temperatures mainly in the 40s.
The next middle to upper trough will approach the Southern Plains
late tonight. Rain chances will return mainly after midnight and
before lunchtime...especially along and south of the Red River.
Drizzle and fog will also be possible during the morning. Some
brief snow mixed with the cold rain cannot totally be ruled out
early Friday morning mainly across northwest OK...but certainly do not
expect any travel problems. The wave will exit the region Friday
night ending precipitation chances. Some patchy fog will be possible Sat am
along the Red River and across portions of western OK with very
light winds and enough bl moisture still present.
Near normal temperatures will return this weekend...with a schc of
light rain/drizzle across central OK within low level moisture
fetch as another middle to upper trough passes overhead. Above average
temperatures are then expected by Monday ahead of a cold front that will
move through the area Tuesday am....drying US out.
