Areas affected...central and eastern Oklahoma into far west-central
Arkansas

Concerning...Heavy snow=20

Valid 240322Z - 240715Z

SUMMARY...Moderate to heavy snowfall to increase in coverage through
the evening. Rates 1"/hr will be possible.

DISCUSSION...Snowfall has increased in coverage across portions of
central Oklahoma over the last hour, with some reports of moderate
snow south of the Oklahoma City metro. Correlation coefficient in
recent radar imagery shows a transition zone of primarily snow and
sleet south of I-40 from roughly northern Pontotoc County north and
east to northern Le Flore County near the Arkansas state line.=20

Initially, drier air was in place with larger dew point spreads but
moistening has been observed with rising dew points and implied
saturating profile which will has lead to an increase in snowfall
rates over the last hour. Moderate to locally heavy snowfall can be
expected to expand in coverage over the next few hours across
central/northeastern Oklahoma with occasional rates around 1"/hr.

Through the evening into early Saturday morning, increasing 850-700
mb frontogenesis will increase across a zone from south-central
Oklahoma into eastern Oklahoma/western Arkansas across a strong warm
advection zone. As moistening continues to occur further east amid
this favorable ascent zone, snowfall rates should increase, with
likely rates around 1"/hr along the I-40 corridor around 06-09z.
