Discussion...
busy upper pattern will result in precipitation chances through the weekend
and into next week. The cold air in place will slowly erode with
time...and wintry precipitation types will gradually transition to liquid
by late in the weekend or early in the next work week.

An upper disturbance in the west-northwest flow aloft will sweep through the
plains today and tonight...and will offer light snow chances for
mainly areas south of I-40. Most precipitation is expected across far southeast
OK...with 1-2 inches possible across Pushmataha and Choctaw
counties. Have issued an advisory for those counties effective from
noon to midnight. As previously mentioned...precipitation chances will
remain ongoing..especially by late Saturday and Sunday as
warm advection gets underway in response to the main upper system
coming ashore to the California coast. Freezing/frozen precipitation by late in
the weekend will mainly be nocturnally driven as warmer daytime
temperatures ensue. Early in the work week...temperatures are
expected to warm significantly...especially by Tuesday as surface
features respond to the approaching trough. The cold front will
move through the region Tuesday night...with showers and
thunderstorms expected along/ahead of the boundary. Will leave a
mention of snow late Tuesday night across NE OK should any
lingering precipitation interact with the colder air. Once this system
pushes through...a period of settled weather appears likely for
the latter half of the work week.
