PREV DISCUSSION... /Issued 320 PM CST Mon Dec 5 2016/

DISCUSSION...
No significant changes have been made to the forecast, other than to
reduce probability of accumulating snow Tuesday night and Wednesday.
Much colder weather is still on the way however.

Initial cold front has moved into northeast Colorado and is expected
to sweep through the Texas and Oklahoma Panhandles this evening.
Clouds and cold air advection will hold Tuesday high temperatures in
the mid-30s to mid-40s.  Post-frontal surface ridge will build
southward, further eradicating any low-level moisture.

Arctic cold front arrives Wednesday morning.  Cold air advection and
clouds across northern sections will keep max temperatures below
freezing across the Oklahoma Panhandle, with highs primarily in the
mid-30s to lower-40s elsewhere.  Have trimmed pops further with
slight chance for light snow confined to mainly northeast part of
forecast area.  No accumulations of snow are expected due to scant
available moisture and lack to upslope flow.  No pops thereafter.

Very cold morning expected on Thursday as massive surface ridge
extends into West Texas.  Winds appear to be too light Thursday
morning and Friday mornings for issuance of wind chill advisories.
Thursday highs expected to remain below freezing over most of the
forecast area.  Moderating conditions begin on Friday as surface
ridge is displaced eastward.  Saturday expected to be the warmest
day of the forecast with highs about 10 to 15 degrees above normal.
Slightly above normal highs expected for Sunday and Monday also.  03

FIRE WEATHER...

or critical fire weather conditions are expected Tuesday through
Monday.  03
