late morning into the afternoon before rain begins to develop
across southeast ok and spread into northwest ar. lower ceilings

.PREV DISCUSSION... /Issued 331 AM CST Mon Dec 5 2016/
Areas of dense fog/freezing fog have developed over portions of eastern
Oklahoma and northwest Arkansas this morning. Short term trends will
continue to be monitored in case the advisory needs to be expanded
any further westward to possibly include the Tulsa metro. Visibilities
will begin to improve by mid morning with the fog lifting.
Scattered areas of light rain will likely move into southeast
Oklahoma this afternoon in association with approaching upper wave
lifting into south Texas. Precipitation will spread across the
remainder of the area this evening into the overnight hours with
the highest rainfall totals across far SE OK/NW AR.
Behind departing wave, initial cold front will move into northeast
Oklahoma late tonight pushing through the remainder of the area
during the day Tuesday. The much advertised secondary push of much
colder arctic air will move through on Wednesday. Areas of light
snow and/or light freezing drizzle will be possible behind the
front, transitioning to all snow by early Wednesday evening. Best
chance for minor snow accumulations will be across far northeast
Oklahoma, near the state line, and across northwest Arkansas. As
mentioned previously, moisture still appears to be limited in the
dendritic growth region which could keep most of the precipitation
in the form of drizzle/freezing drizzle for much of the day Wednesday.
Precipitation types will continue to be refined in the next couple
Bitterly cold conditions will develop Wednesday night into Thursday
morning behind the cold front with wind chills likely falling
into the single digits. Arctic high pressure will build directly
over the region by Friday morning and with light winds/clear
skies, lows temperatures in the teens forecast for much the area.
Cold/brisk conditions will likely continue early Saturday morning
as southerly winds begin to increase as surface high shifts east,
especially across eastern Oklahoma. Warmer weather expected
Saturday afternoon into Sunday with limited rain chances returning
Sat night/Sun across southeast Oklahoma/northwest Arkansas ahead
of next front.
