...New SHORT TERM...

.SHORT TERM...
(The rest of tonight)
Issued at 954 PM CDT Mon May 2 2022

Currently a line of strong to severe thunderstorms continues to
move southeast through eastern Oklahoma and western Arkansas. A
cold front is also entering northeast Oklahoma bringing in some
cooler air and gusty northerly winds while a stationary warm
front continues to hang out near I-40. The storms will continue to
push to the east and southeast and will encounter an unstable
airmass south of the warm front characterized by temperatures in
the upper 70s and dewpoints in the upper 60s. The line should
maintain a severe threat into the overnight hours. Damaging wind
gusts will be the main threat, though brief tornadoes will
continue to be a possibility with strong low level shear in place.
Storms should clear the forecast area by around 1-2 AM as the
front sweeps through. Along with the severe threat, these storms
will dump very heavy rainfall in a quick amount of time, posing a
localized flooding threat particularly for low lying and other
flood prone areas.

Bowlan

.LONG TERM...
(Tonight through Monday)
Issued at 154 PM CDT Mon May 2 2022

Most of the storms will exit the area before 12z, with a more
stable and cooler airmass spreading over the area Tuesday. This
will be a short respite however as next upper system already
moving across Pac NW this afternoon. Moisture transport will re-
commence Tuesday night with at least scattered convection
returning as warm front begins to lift back north. Warm sector
expansion within sheared environment will again yield severe
weather potential, possibly significant, though this will largely
be determined by eventual warm frontal placement and timing of
upper wave, which are still uncertain. Given another round of
significant rainfall however, the flooding threat will likely be
higher by this time and another flood watch will most surely be
needed for Wed and Wed night.

Storm chances linger into Thursday to some degree, with
continuing spread in the mid range guidance lending more
uncertainty. By Friday and Saturday mid level ridging should
result in quiet period before another trough sets up to the west.
Some storm chances will return by Sun/Mon as a result with
temperatures on the warm side.

&&

.AVIATION...
(00Z TAFS)
Issued at 622 PM CDT Mon May 2 2022

Mature line of strong to severe thunderstorms will sweep through
the northeast OK sites through 01-02Z and into northwest AR/southeast
OK 03-05Z. Expect widespread MVFR cigs, with localized IFR conditions
with the heavier thunderstorms. Breezy northwesterly winds will
develop behind the line of storms as the cold front surges southeast.
Should see some improvement in cigs by late Tuesday morning and into
the afternoon.

much of Eastern Oklahoma.

	AREA...Primarily Northeast Oklahoma.
    ONSET...Ongoing.

SEVERE THUNDERSTORM.
	RISK...Critical.
	AREA...Eastern Oklahoma and Northwest Arkansas.

SIGNIFICANT WINDS.
	RISK...Limited.
	AREA...Eastern Oklahoma and Northwest Arkansas.
	ONSET...Ongoing.

DISCUSSION...
A few scattered strong thunderstorms will be possible across
southeast Oklahoma and western Arkansas over the next few hours
near and south of a warm front draped across the area. The threat
of more widespread severe thunderstorms will increase over the
next couple of hours and storms move into the region from the
west. A line or broken line of storms will move into northeaster
Oklahoma in advance of a southward progressing cold front this
evening. Damaging winds will be the primary threat, though strong
low level shear will allow for a tornado risk to persist mainly
across northeast Oklahoma through about 10 PM. The line is
expected to quickly move southeast across the CWA and gradually
weaken throughout the night. Additional locally heavy rainfall on
top of what fell this morning could also lead to some flash
flooding of low lying and urban areas especially. The heaviest
rainfall totals are expected across northeast Oklahoma and
northwest Arkansas.

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

.DAYS TWO THROUGH SEVEN...Tuesday through Sunday.
TUESDAY...Thunderstorm Potential.
WEDNESDAY AND THURSDAY...Severe Thunderstorm Potential...High Wind Potential...
          Heavy Rain Potential.
FRIDAY THROUGH SUNDAY...High Wind Potential.

EXTENDED DISCUSSION...
Thunderstorm chances will diminish early Tuesday with the next
storm system impacting the area on Wednesday. Storms will increase
early Wednesday with a limited risk of severe weather. Conditions
will become increasingly unstable and favorable for severe
weather during the day Wednesday. Storms which initially develop
west of the region Wednesday afternoon will spread eastward
overnight with a risk of severe weather and flash flooding. Storm
chances lessen on Thursday with dry weather expected over the
weekend.
