.AVIATION...
CONCERNING TAF SITES KTUL/KRVS/KBVO/KMLC/KXNA/KFYV/KFSM/KROG.
Complex aviation forecast tonight. Periods of low cigs and
possibly low vsbys as well can be expected tonight at the TAF
sites. An upper storm system lifting northeast over the region
will bring rain mainly to KFSM tonight. A cold front will push
into the region from northwest to southeast on Tuesday in the wake
of the exiting system, finally bringing a return to VFR conditions
to all sites by afternoon.

.PREV DISCUSSION... /Issued 247 PM CST Mon Dec 5 2016/

DISCUSSION...
Upper low currently across south central Texas will continue
lifting northeast and weaken as it moves through southern Arkansas
overnight. Rain chances associated with this feature will mostly
be confined to southeast Oklahoma and northwest Arkansas tonight.
Attention turns to the arctic airmass that will impact the region
by midweek. Initial push of cooler air will move into the area
overnight...with the main surge to enter northeast Oklahoma
Wednesday afternoon. Moisture profiles suggest limited chances for
any accumulating precip associated with the broad upper trough
that will pass Wednesday and Wednesday night. Have cut down on qpf
and snow totals from previous forecast...and will have the best
chance for snow across far northeast OK and northwest AR. Once
this airmass settles over the plains...very cold temperatures that
hav not been seen in quite sometime can be expected
Thursday...and especially Friday morning where widespread
overnight low temperatures in the teens are expected. Airmass
loses its grip over the plains for the start of the weekend...and
a quick warmup will ensue. Precip chances will increase some for
the last half of the weekend across southeast Oklahoma and
northwest Arkansas as moisture increases ahead of the next system.
