1052 PM CST Mon Feb 21 2022

...New AVIATION...

.SHORT TERM...
(The rest of tonight)
Issued at 922 PM CST Mon Feb 21 2022

At mid evening...southerly low level flow continued to transport
moisture back into the region ahead of a cold front currently
positioned across Southeast Kansas. This moisture was allowing for
60+ deg dewpoints to pool along and south of Interstate 40...while
mid to upper 50 dewpoints were common elsewhere over the CWA. Also
at the surface...a warm front type surface boundary was located
near the northern portion of the 60 deg dewpoints from Pittsburg
co into Sebastian co. The combination of the mentioned above along
with an increasing low level jet....strong shear values and 400+
m2/s2 low level helicity values have allowed for continued
destabilization across the CWA. Thus...with showers and storms
entering Southeast OK...a tornado watch has been issued for much
of East Central and Southeast Oklahoma as well as Northwest
Arkansas through 4 4AM.

Overnight tonight...thunderstorms are expected to expand in
coverage across the CWA as an embedded mid level wave lifts
northeast within the southwesterly flow aloft...while at the same
time the cold front makes its way into Northeast Oklahoma. The
strong shear values...50-70KT low level jet and 50s/60s dewpoints
will continue to aid in storms having the potential to become
severe. Large hail and damaging winds look to be the primary
threats. However with the surface boundary mentioned
above...storms rooted along/interacting with the boundary will aid
in a continued tornado potential into the overnight hours. Latest
CAM /short- term guidance continues to show max updraft helicity
values over an area from Pittsburg co to Madison co overnight.
Thus...these locations will have the higher tornado potential.
Also possible overnight...will be the potential for bows/line
segments which could develop quick spin- ups along the leading
line. Severe potentials will remain likely through much of the
overnight and then start to weaken late tonight with the majority
of the severe potential ending around sunrise Tuesday. Precip
looks to taper off from west to east late tonight/early Tuesday
morning and exit Northwest Arkansas by mid/late morning.

The cold front looks to be a little south of Interstate 44 early
Tuesday morning with falling temperatures and gusty northerly
winds behind the frontal passage. Thus...lows temps tonight look
to be around 14z with low 30s in Osage co to mid 50s/lower 60s
ahead of the front in Southeast Oklahoma and much of Northwest
Arkansas. For the evening update...have adjusted pops/wx based on
latest trends/short-term guidance and also adjusted timing of the
cold front late tonight. The rest of the forecast seems in good
shape at this time.

&&

.LONG TERM...
(Tuesday through Monday)
Issued at 107 PM CST Mon Feb 21 2022
The showers and thunderstorms are set to exit the area Tuesday
morning as the cold front moves to the south and east. The
temperature forecast for Tuesday is tricky with temperatures
generally falling or remain steady across much of the area.
However, the cold air will become more noticeable Tuesday night
into Wednesday morning with lows in the teens and twenties Wednesday
morning.

With these cold temperatures in place at the surface, the next couple
of rounds of precipitation Wednesday and Thursday will be problematic.
The first round of precipitation will commence on Wednesday morning
as isentropic lift associated with the southwesterly flow aloft
combines with a subtle shortwave to produce a wintry mix of freezing
rain and sleet that will spread to the northeast across the region
through the day Wednesday before tapering off Wednesday evening. The
next round is expected Thursday morning into Thursday afternoon as
a mid-level shortwave moves out of the Southwest United States and
across the Plains. Again this will primarily be a mix of freezing rain
and sleet, especially Thursday morning. The freezing rain may change
over to rain by Thursday afternoon across southeast Oklahoma into
west-central Arkansas. Some light snow may also be possible Thursday
afternoon across portions of northeast Oklahoma and northwest Arkansas
as the event begins to wind down. The confidence in the sleet and
ice accumulations meeting Winter Storm or Ice storm criteria is
high enough that a Winter Storm Watch has been issued for all of
eastern Oklahoma and western Arkansas from 12z Wednesday through
00z Friday. During the two day period some locations could see
around 1/2 inch of ice while others areas could see around 1 inch
of sleet accumulations. Still difficult to actually pinpoint precip
types and amounts but significant impacts to travel are expected.
Power outages could also be problematic with northerly winds of
10 to 15 mph during this time. The precipitation is expected to
come to an end Thursday evening as the mid-level disturbance exits
to the east.

Warmer temperatures are expected Friday and into Weekend. However,
there will be another chance of a light wintry mix across southern
portions of the area as another mid-level shortwave sweeps across
the area.

&&

.AVIATION...
(06Z TAFS)
Issued at 1047 PM CST Mon Feb 21 2022

Numerous showers/storms are ongoing across southeast OK into
northwest AR and expect areas of reduced cigs and visibilities for
through the night for these sites. In addition, could see some
brief gusty winds for KTUL/KRVS through around 09Z along the northern
edge of the heavier precipitation. The strong cold front is
beginning to move into northeast OK and will sweep through the
entire region by 12-13Z with precipitation tapering off with the
frontal passage. MVFR cigs may persist through the morning with
improving conditions expected by the afternoon.

	ONSET...Ongoing.

DISCUSSION...
Thunderstorms will continue to spread northeast across much of
eastern Oklahoma and northwest Arkansas overnight tonight ahead of
a cold front moving into the region. Sufficient instability and
wind shear are expected to support severe storms with the greater
potential over east central and southeast Oklahoma as well as
northwest Arkansas. Large hail and locally damaging winds are the
primary hazards. A tornado potential also remains possible with
the possibility of quick spin ups along the leading line of
storms through the overnight hours. Locations with the higher
tornado potential are forecast to be across southeast Oklahoma
into northwest Arkansas. Additionally, an axis of heavy rainfall
is likely to develop with the heaviest rainfall forecast across
parts of southeast Oklahoma into northwest Arkansas where a flood
watch is in effect tonight. Isolated storms may continue into
Tuesday morning before spreading farther east as the strong cold
front moves further into the region.

Also, overnight, breezy south winds will become gusty northerly
winds behind the cold front late tonight. The cold front is
forecast to be across northeast Oklahoma early Tuesday morning.
This wind shift could impact any ongoing fire suppressions.

SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT...
Activation of the Regional Spotter Network Likely.

.DAYS TWO THROUGH SEVEN...Tuesday through Sunday.
TUESDAY...Thunderstorm Potential...High Wind Potential...Dangerous Wind
		  Chill Potential.
WEDNESDAY AND THURSDAY...Winter Weather Potential...Dangerous
						 Wind Chill Potential.
FRIDAY...Dangerous Wind Chill Potential.
SATURDAY...Winter Weather Potential.
SUNDAY...No Hazards.

EXTENDED DISCUSSION...
Impactful winter weather is expected across eastern Oklahoma and
northwest Arkansas Wednesday through Thursday. A mixture of
freezing rain and sleet will impact travel conditions and there
will be potential power grid issues across locations with the
heaviest icing accumulations. The heaviest accumulation periods
currently appear to be Wednesday during the day and again
Thursday during the day. Precipitation is forecast to end from
west to east Thursday afternoon and evening. In addition to the
winter weather, gusty northerly winds and sharply colder
temperatures will overspread the region on Tuesday. Very cold wind
chill values will develop Tuesday night and continue at times
through Friday night.

An upper level disturbance may bring another round of light wintry
weather on Saturday.

EMERGENCY MANAGEMENT PLANNING STATEMENT...
Severe weather potential will increase tonight with a quick
transition to winter weather impacts Wednesday through
Thursday. Anticipate travel impacts through the winter event and
understand power interruptions are possible within any corridor of
heavier icing amounts.
