.SHORT TERM...
(Through Wednesday)
Issued at 1025 PM CST Tue Jan 27 2026

High clouds continue to move across the region tonight, but
satellite trends indicate they will eventually scatter from the
west after midnight and mostly east of the area by early
Wednesday morning. Some moistening of the boundary layer has
occurred generally along and south of I-40, where current temp/dew
point spreads are now just a few degrees, with a bit drier
conditions persisting to the north. Given light winds and the
eventual loss of higher clouds, appears that at least patchy dense
fog is likely, and with temperatures falling into the teens and
single digits, the potential for enough freezing fog to induce
additional travel issues is high enough to warrant an advisory,
which will run from 09-16z.

With continued light boundary layer flow most of Wednesday, any
fog or low clouds could take some time to dissipate, but most
areas should eventually see enough sun to bring temperatures back
above freezing Wednesday afternoon, similar to what was observed
today.

.LONG TERM...
(Wednesday Night through Tuesday)
Issued at 1025 PM CST Tue Jan 27 2026

Milder conditions Wednesday night with more consistent south
winds ahead of an approaching shortwave moving through the
Rockies. This system may result in a few light rain or snow
showers across mainly far northeast Ok and northwest AR Thursday,
but POPs remain below mentionable for the most part and do not
expect any impacts from any snow. A cold front will move through
in the wake of this system later Thursday with cooling effects
beginning Thursday night. A much more substantial push of cold
Arctic air will then arrive by Friday, with temperatures dropping
back into the single digits or even a bit below zero by Saturday
morning, with anticipated wind chills likely necessitating cold
weather headlines at that time. A few flurries also likely with
this cold surge, but again nothing impactful in the way of
precipitation.

After a very cold day Saturday, temperatues should begin to
modify, though this will continue to be tempered early next week
with expected lingering snowpack. By next Tuesday moist air from
will increase from the south and result in a chance of rain as an
upper system approaches from the west.
