Area Forecast Discussion
National Weather Service Norman OK
822 PM CST Tue Jan 16 2018

.UPDATE...
Another cold night in store. Several locations are already near
forecast lows, so have dropped overnight lows a couple of degrees
across much of the area. South winds return across the west
overnight, which may result in temperature trend leveling off or
even rising a degree or two late. Otherwise, no oter changes at
this time.

PREV DISCUSSION... /issued 348 PM CST Tue Jan 16 2018/

DISCUSSION...
Another cold night is in store lows generally 10 degrees or less
and minimum wind chill values between -5 and +10. There may be
some potential for wind chill values below -5, but the area and
time covered would be small if it occurs, so will not issue a wind
chill advisory.

Temperatures will warm through the week and become quite warm (by
January standards) by Saturday. A mid-level longwave trough
approaches the area and brings some shower/thunderstorm chances
Saturday night and Sunday. There is not much cold air to tap into,
so do not expect much chance of winter precipitation. Showers will
be most likely in the east as western areas may stay dry with a
large dry slot predicted wrapping into this system.

Along those lines, Sunday will likely have near-critical fire
weather conditions in the west where it will stay dry, and winds
will increase as this system moves through.
