.PREV DISCUSSION... /Issued 404 PM CDT Sun Apr 30 2017/

DISCUSSION...

The closed upper low over southern and eastern Kansas will
continue to move away from the forecast area tonight. Drier air
will work into the Panhandles and allow for skies to clear and
wintry precipitation to end from west to east this evening.
Northwest and north winds 25 to 35 mph or higher with gusts to
near 50 to 60 mph will diminish quickly after sunset this evening.
Winds should decouple to 10 mph or less after sunset. Blizzard
Warning will remain in effect for the western and central Oklahoma
Panhandle and the northwest Texas Panhandle until 00Z Monday due
mainly to the strong winds causing blowing and drifting of the
snow which will result in continued near whiteout conditions until
the winds subside. Cut back highs Monday from MOS guidance numbers
as snowpack will result in much cooler temps mainly across the
northwest half of the forecast area. Issued a Freeze Warning
tonight into Monday morning mainly for the Oklahoma Panhandle and
the northwest and north central Texas Panhandle as temps forecast
to drop into the upper 20s to lower 30s. Other locations east and
south of the Freeze Warning will need to be closely monitored for
inclusion into the Freeze Warning should temps fall much more
quickly than currently forecast.

Northwesterly flow aloft Monday will give way to a shortwave
trough approaching the forecast area by Tuesday night and early
Wednesday. A cold front will push south across the Panhandles
Tuesday and Tuesday evening with convection expected across most
of the forecast area Tuesday night. Very progressive upper trough
will exit the Panhandles by early Wednesday allow for drier
conditions Wednesday through the end of the week into next
weekend. Much warmer conditions expected late this week into the
weekend.
