.PREV DISCUSSION... /Issued 341 AM CST Sun Jan 14 2018/

DISCUSSION...
Warmup today expands further, with all sections rising into the
50s.  Comfort will be short-lived as arctic cold front late
tonight and Monday morning brings much colder air.  Highs Monday
expected to remain below freezing across northern half of forecast
area, with only far southeastern Texas Panhandle rising above 35
degrees Fahrenheit.

Have retained low pops for light snow Monday and Monday evening,
primarily across northwest parts of the Combined Texas and
Oklahoma Panhandles.  Shortwave trof in northwest flow may
produce light precipitation during the day, with upslope flow
increasing during the evening.  Do not expect accumulating snow
due to limited moisture and lack of isentropic lift.

North winds following frontal passage persist late Monday night
and Tuesday morning, producing wind chill values below minus 5
degrees in eastern sections.  Cold conditions continue Tuesday,
with only western sections rising into the mid-30s.

Airmass modification gets underway on Wednesday, as mid-level flow
loses its meridional component.  By Thursday, high temperatures
return to values near normal.

Warmer still Friday and Saturday with maxima mostly in the 60s as
lee trof develops.  Strong shortwave trof on Saturday may produce
strong winds.  No pops other than Monday and Monday evening.  03

FIRE WEATHER...
No elevated or critical fire weather conditions are expected
through Thursday, as relative humidity values remain above
necessary thresholds.  Elevated fire weather conditions may
develop on Friday and Saturday as dry southwest winds increase. 03
