.PREV DISCUSSION... /issued 402 AM CST Mon Jan 15 2018/

DISCUSSION...
Very light snow with little accumulation is expected over north
central Oklahoma this morning when a short-wave trough embedded
in the long-wave trough passes over the eastern part of Oklahoma.
Later today there remains a chance for light freezing rain,
sleet, or snow to change to snow this evening in southeastern
Oklahoma as the wave exits that region. It still appears that the
bulk of the precipitation will be to the south and east of this
area. The cold front that will pass coincidentally will bring in
much colder air today. With north winds tonight, wind chill values
in the northern half of Oklahoma will arrive to -5 degrees F. or
less, and an advisory for that hazard is in effect after midnight.
The cold air mass will settle across Oklahoma Tuesday and Tuesday
night with that being the coldest day of the week. Maximum
temperatures in north central OK will be aroudn 20 degrees while
southwest Oklahoma will be just below freezing. Wednesday morning
will be similarly cold to Tuesday, but without much wind. A
strong warming trend starts Wednesday as the long-wave trough from
the southern plains to Hudson Bay is replaced by weaker,
downslope flow from the northwest or west for the second half of
the week. By Saturday a trough from the southwest will have
completely changed the overall pattern and temperatures are
expected to be 15 to 20 degrees above normal. Later Saturday or
Sunday there may be sufficient moisture for a chance of rain in
the eastern half of Oklahoma.
