Area Forecast Discussion
National Weather Service Norman OK
515 PM CST Wed Feb 6 2019

.DISCUSSION...
00Z TAF discussion.

&&

.AVIATION...
LIFR conditions will continue this evening before gradual
improvement late tonight into Thursday morning as a cold front
brings drier air into the area. Will also see a prevailing period
of tsra at most locations from mid-eveing into the overnight with
some freezing precip across north before it ends after 09Z. VFR
conditions expected area-wide by 15Z/16Z.

&&

.PREV DISCUSSION... /issued 347 PM CST Wed Feb 6 2019/

DISCUSSION...
The nearly stationary front remains...well...stationary...across
southeast Oklahoma, north Texas, and the eastern Texas Panhandle.
The few locations where clouds have cleared have temperatures well
above the upper 20s and 30s that cover the majority of our
forecast area.

Freezing drizzle and dense fog have been common across central
and northern Oklahoma today, and this is expected to continue into
the evening. Meanwhile, strong thunderstorms are also expected
across much of Oklahoma and north Texas this evening into the
overnight hours. Elevated instability will be quite strong, so
large hail is likely to be a problem under the stronger storms
through about 2 am.

The storms may help reduce the dense fog, so the current Dense Fog
Advisory is timed to expire around the time that storms should
become more numerous. In any case, the arrival of the reinforcing
cold front after midnight will clear out the fog. Unfortunately,
the warm and moist air above the low-level cold air will continue
to produce drizzle and rain, so freezing rain is expected over
parts of central and northern Oklahoma after midnight, especially
behind the new front. This freezing rain prospect is the reason
for the southward extension of the Winter Weather Advisory that
was done earlier today.

During the morning on Thursday, upper-level support will diminish
(as the upper wave passes overhead), and moisture will also
diminish across Oklahoma and north Texas. This should bring a
definitive end to the fog, drizzle, rain, freezing rain, and
storms by about 9 am, possibly earlier. It will, however, be quite
chilly and breezy. Wind chill values will approach advisory
levels in northwest Oklahoma.

After several dry days, there will be another chance for rain,
mostly over the eastern 2/3 of Oklahoma, Saturday night through
Tuesday, as moisture and additional upper-level systems arrive
again. Temperatures over northern Oklahoma will be near freezing
again during part of this time, so some light freezing rain will
once again be a possibility.
