DISCUSSION...
Will cancel the Winter Weather Advisory before the
issuance of this forecast package. There will still
be some light snow or snow flurries into the early
evening hours. However, little if any additional accumulation
is expected. Will leave the Wind Chill Advisory in place
as is.

The much advertised arctic cold front has blasted through
the area Today and is currently across southern Arkansas
into north Texas. As mentioned before light snow or snow flurries
will continue into the early evening hours across portions of
far northeast Oklahoma and northwest Arkansas before fading.
Additional light snow will be possible this evening and into
the overnight hours across southeast Oklahoma into west-central
Arkansas with forcing occurring behind the cold front. Any accumulations
are expected to be light in nature and will not be issuing a
Winter Weather Advisory for this activity at this time. The
evening shift will monitor closely and issue and an Advisory if
needed.

The big story over the next couple of days will be the bitterly cold
temperatures. Lows tonight are expected to be in the single digits to
mid-teens. The winds will make it feel more like zero to minus 20 below
across a good portion of eastern Oklahoma and western Arkansas.
Therefore, a Wind Chill Advisory has been posted for almost all of
the area with the exception of Choctaw county in extreme southeast
Oklahoma. Temperatures are set to be even colder Tuesday night into
Wednesday morning with temperatures ranging from around five below
zero to around 10 degrees as the 1043 mb surface high settles over the area.
The coldest temperatures will be across far northeast Oklahoma and
far northwest Arkansas where some snow will still be on the ground

A warm up will commence on Thursday and continue right into the weekend
as the surface high shifts to the east of the area. By Saturday, temperatures
are expected to be in the 60s across a good deal of the region in advance of
the next cold front that will work through the area on Sunday
with chances of showers and even thunderstorms.
