(Rest of today and tonight)
Issued at 1258 PM CST Wed Feb 12 2025
A low amplitude, mid-level trough will skirt the region tonight.
There are a few CAMs that suggest a mid-level moist layer may
result in a brief period of light snow/flurries. The timing of
this will be mainly after midnight across parts of west
central/southwest Oklahoma. If this occurs, little or no impact is
expected. Otherwise, very cold surface high pressure will build
over Oklahoma. This will result in lighter winds, which reduce the
effect of wind chill. However, overnight lows will dip into the
single digits across far northwest Oklahoma with temperatures in
the teens elsewhere. Wind chill values are expected to dip to
around -5 degrees F across parts of northern and western Oklahoma,
so we will issue a Cold Weather Advisory for this area.
&&
.SHORT TERM...
(Thursday through Friday night)
Issued at 1258 PM CST Wed Feb 12 2025
Some low clouds may linger through the early morning hours
Thursday; otherwise, another very cold day is expected with
afternoon high temperatures well below average. There will likely
be some lingering influences on high temperatures where heavier
pockets of sleet/graupel/snow fell early Wednesday morning.
A southerly wind will return and increase Thursday night. High
clouds are also expected to increase from the west with perhaps
low clouds returning to parts of south central and southeastern
Oklahoma. The increase in wind will keep temperatures much warmer
Thursday night, but temperatures will still be rather cold
(including a wind chill).
Temperatures will moderate some on Friday with return flow. By
Friday afternoon and especially during the evening/overnight,
higher dew point air (dew points in the 40s) will return.
Meanwhile, a low amplitude shortwave trough is expected to enter
western Oklahoma ahead of a broader trough to the west. This may
result in a few showers across southeast Oklahoma during the
evening and generally east of I-35 during the overnight.
&&
.LONG TERM...
(Saturday through next Tuesday)
Issued at 1258 PM CST Wed Feb 12 2025
A trough will move across the southern Plains on Saturday. An
associated surface low will push a cold front through at least
northern Oklahoma during the morning. By early to mid afternoon
the front will be across parts of south central and southeast
Oklahoma. There are certainly some model timing issues with this
front, but overall, colder and drier air will overspread the area
by Saturday night. A slower frontal timing could result in
thunderstorm development across far southeast Oklahoma, but
chances are much better to our south and east. Temperatures may
cool sufficiently across far northern Oklahoma for some light
snow, but any snowfall amounts look light.
Well below average temperatures are expected on Sunday but will
moderate some by Monday.
Another storm system will approach the area late Monday into
Tuesday. Rather cold air is expected with this system as well.
Currently, there is a low to medium (20%-50%) chance of snowfall
greater than 1 across mainly the northern third to half of
Oklahoma.

.AVIATION...
(18Z TAFS)
Issued at 1104 AM CST Wed Feb 12 2025
With the exception of northwest Oklahoma, most of the wintry
precipitation has ended and the aviation forecast is transitioning
mainly to a ceiling forecast. Expect some modest lifting of
ceilings this afternoon. Lower clouds should start to gradually
clear out across southwestern sites this evening, though
confidence is low in how quickly this occurs. North winds will
follow a diurnal pattern of gusty winds this afternoon, decreasing
in the evening.
