Areas affected...Far Eastern Oklahoma...Central and Northern
Arkansas.

Concerning...Winter mixed precipitation=20

Valid 240718Z - 241115Z

SUMMARY...Heavy snowfall, with rates up to 1 inch per hour, are
expected to develop from parts of far eastern Oklahoma eastward
across much of central and northern Arkansas over the next several
hours. The snow should be mixed with sleet over parts of central
Arkansas.

DISCUSSION...The latest water vapor imagery shows a mid-level trough
in the western U.S., with a belt of strong zonal westerly flow over
much of the central and eastern U.S. Lift is currently maximized
over the Ark-La-Tex and southern Ozarks, where a shortwave trough
appears to moving through the flow, and the right exit region of an
expansive mid-level jet is located. Within this zone, radar shows a
large area winter precipitation, which is organized into an
east-to-west band. This band is being supported by strong lift
associated with the northern edge of a 35 to 45 knot low-level jet.
As the low-level jet shifts eastward across south-central Arkansas
over the next 3 to 6 hours, isentropic lift will become maximized in
parts of central and northern Arkansas. Snowfall rates are expected
to peak near 1 inch per hour within the heaviest part of the band.
On southern edge of the band, a sleet/snow mix is expected. The
potential for heavy precipitation should continue over the next four
to six hours.
