- Rain chances increase Sunday, especially north of I-40 (40-70% chance).
A cold front across the area will result in a wide range in
temperatures.
- Localized fire weather potential will continue for the next few
afternoons in areas with minimal rainfall.
- An unsettled weather pattern continues over the next week with
multiple periods of showers and thunderstorms. There is the
potential for both severe weather and heavy rainfall hazards in
the mid to late week period.

(Through Sunday)
Issued at 1026 PM CST Sat Feb 28 2026
A midlevel shortwave intersecting a surface cold front will continue
to promote scattered showers and isolated thunderstorms tonight. As
forcing weakens, lingering precipitation will die off by dawn.
Overall, total accumulation will be minimal, with most locations
seeing little to none. Low temperatures will vary significantly,
ranging from the upper 30s to low 40s in the far north (north of the
cold front), to 50s near and south of the front. The front is
expected to settle near the I-44 corridor overnight tonight.
During the day Sunday, the front will retreat back north, with mild
air surging northward as well. Afternoon highs will again vary quite
a bit. North of the front (roughly Highway 412), highs will be in
the 50s to low 60s. South of the front, upper 60s to upper 70s are
expected. Shower and thunderstorm activity will reinvigorate during
the afternoon and evening hours as another mid level shortwave
trough approaches. Rainfall will probably be limited, but the
chance for more widespread measurable rain will be higher than
Saturday, especially if some of the more aggressive CAMs like the
HRRR are correct. Overall, forecast PoPs will range from 40-70%
north of I-40 to 20- 40% south of there. Heavy rain and severe
weather are not expected. Limited fire weather potential may
develop during the afternoon, especially across southeast OK where
the threat of rain is lower.

(Sunday Night through Saturday)
Issued at 1026 PM CST Sat Feb 28 2026
An active weather pattern will remain in place for the remainder of
the forecast period. The big picture seems to be in good agreement
amongst most modeling guidance, which is that we will have moist
southwest flow and periodic mid level disturbances passing through.
These features will kick off several rounds of showers and
thunderstorms. With that said, Monday and Tuesday appear to be
relatively slower days, with less meaningful storm activity.
By midweek that will begin to change with a more robust trough axis
providing better forcing to an already moist and unstable airmass.
According to EPS climatology, much of the week will feature PWAT
values in the 95-99th percentile relative to climatology. A more
widespread precipitation event is expected Wednesday-Thursday, with
potentially locally heavy rainfall and isolated severe thunderstorm
activity. Then for Friday and into the weekend a deeper western
trough will further increase the moist southwest flow and upper
level diffluence over the area. This is likely to keep periodic
showers and thunderstorms in the region.
With all of this said, this is the type of pattern where you can
have good confidence in the big picture but low confidence in the
details. The model guidance shows significant uncertainties in
the exact timing and location of each of the features that were
mentioned, so the forecast details will likely shift around in the
days ahead. Separate from the rain/storm threat, it's worth
mentioning that the airmass in place will also remain warm through
the extended. Most days will see temperatures above normal, some
well above normal. Tuesday will likely be the warmest day with 70s
to low 80s being expected. For areas that do not see meaningful
rainfall, fire weather will continue to be a concern through
midweek.

Mainly VFR conditions will prevail through the day today. Shower
and thunderstorm chances will increase later this afternoon at the
northeast Oklahoma sites and this evening at the rest of the
sites. A shallow frontal boundary will oscillate across the area
today before moving south by this evening. The boundary will
likely get hung up in the higher terrain of northwest Arkansas
overnight. MVFR conditions will become common at the northeast
Oklahoma sites later this evening and overnight, with MVFR
conditions delayed at the other sites until near or just beyond
the end of this forecast period.

(06Z TAFS)
Issued at 1026 PM CST Sat Feb 28 2026
VFR conditions will prevail through much of the TAF period, with
expanding showers during the latter 6 hours leading to prevailing
MVFR conditions at least at the NE OK and far NW AR sites. While not
prevailing, similar conditions will be included in a PROB30 at MLC.
The chance of thunderstorm impacts during that same time frame is
non zero but low enough to leave out of the TAF for now. Existing
widely scattered showers with embedded thunderstorms near MLC and
FSM may impact these two terminals during the first few hours of the
TAF period. Will continue with the PROB30 group containing a
thunderstorm mention for MLC given the current proximity and
continued CAM output showing a higher chance there than at FSM. It
is more likely that the activity will remain south of FSM during
this time frame but will include a VCSH mention. Some uncertainty
exists regarding the development of a more cohesive batch of
thunderstorms by mid afternoon tomorrow that would be most likely to
affect the NE OK and W AR sites, with the HRRR continuing to be
bullish in this regard. Will continue with the PROB30s at these 7
sites late afternoon into very early evening. Winds will be gusty at
times from the north to northeast following the frontal passage at
the NE OK sites.

Corridor of high based showers and and isolated storms ongoing
across E OK will continue eastward through the afternoon with
rainfall amounts remaining light but isolated lighting hazard risk
for outdoor activities. Cold front moves through NE OK into far NW
AR late overnight with a continued axis of elevated convection
possible from SE OK through NW AR though overall coverage is
likely to remain low.

.LONG TERM...
(Tomorrow through Saturday)
Issued at 1150 AM CST Sat Feb 28 2026
The cold front evolution Sunday through Monday will have a large
impact on local conditions with expanding cloud cover and rain
chances along and north of the front with continued unseasonably
warm temperatures south of the boundary. An expanding area of
convection appears likely by mid morning Sunday north of the front
across S KS with and ESE motion keeping higher rain chances across
far NE OK into NW AR from afternoon through evening. This scenario
will reinforce the frontal zone and further sharpen the
temperature gradient across the region.
The frontal zone will attempt to lift northward Sunday night into
Monday and likely become more aligned SW to NE with widely varying
temps expected again across the forecast area. Precip chances will
gradually wane as weak ridging aloft develops downstream of the
evolving southwestern CONUS troughing.
Unseasonably warm temperatures return area wide Tuesday as the
warm sector spreads northward. Shortwave trough is currently timed
to eject across the central CONUS Tuesday night into Wednesday
with an increase in shower and storm chances with the associated
frontal passage. The degree of moisture return will be the focus
for any uptick in severe weather potential as wind fields will be
strong with the wave passage. The unsettled pattern continues into
late week with more pronounced troughing across the western CONUS
and multiple periods of showers and storms likely across the
Plains late week into next weekend.

VFR conditions should prevail thorugh the period, except during
on-station impacts from showers and thunderstorms. MLC is the most
likely site to see a thunderstorm overnight given recent CAM
output and an overnight PROB30 group will be maintained at that
site. Additional development most likely during the afternoon
tomorrow will have the highest chance of affecting the other
sites, with a lesser chance at MLC prior to tomorrow evening.
As such, PROB30 groups will be included for the other sites
tomorrow afternoon. Winds will shift from a southerly direction to
a northerly direction behind the cold frontal passage tonight at
the NE OK sites, with gustiness expected. A wind shift will also
occur at the far NW AR sites but less gustiness is expected there.
