.PREV DISCUSSION... /Issued 523 AM CDT Fri Apr 28 2017/

DISCUSSION...
As T.S. Eliot said in 1922, "April is the cruelest month."

A potent mid-level low pressure center is expected to bring
accumulating snows to the northwest part of the Combined Texas and
Oklahoma Panhandles Saturday and Saturday night.  At this time
the higher elevations of Cimarron County Oklahoma look favored to
receive a significant snowfall.  We have issued a Winter Storm
Warning for snow for this western-most county of the Oklahoma
Panhandle, with a winter storm watch for adjacent counties.

For today however, the potential for a few strong to severe
thunderstorms will exist for the southeast Texas Panhandle this
evening as pooling moisture behind a cold front will be augmented
by a mid-level shortwave trof.  Rain and a few thunderstorms can
be expected tonight across the Panhandles.

Strong north winds tonight will bring freezing temperatures and
the potential for light snow to mix in with the rain in the
northwest.

As the mid-level low moves through New Mexico and tracks across
the northwest and north part of the forecast area, strong north
winds will continue Saturday and Saturday night.  Isentropic lift
will assist in precipitation production.

By Sunday morning, precipitation is expected to diminish in
intensity as the mid-level low departs.  Freezing temperatures
will likely occur across northern and western sections.  Rain
showers may occur Sunday afternoon across mainly northeast
sections.

Following one last freeze on Monday morning, more typical spring-
like temperatures are expected through Thursday.
