...New SHORT TERM, LONG TERM...

.SHORT TERM...
(Through Tonight)
Issued at 205 PM CDT Mon Jun 3 2024

The strong/marginally severe convective bow echo continues to
surge eastward/southeastward in far Southeast OK and West-Central
AR early this afternoon. Wind gusts up to 60 mph and hail up to an
inch in diameter continue to be the primary hazards.
Additionally, very heavy rainfall has been observed, with radar
estimating instantaneous rainfall rates between 2-4+ inches per
hour in the heaviest rain. Nuisance flooding and flash flooding
will remain a concern until the convection pushes out of the
forecast area mid-late afternoon. Some of the heaviest rain
amounts have totaled between 1 and 3 inches, per surface obs and
Oklahoma Mesonet obs.

Latest 12z runs of the CAMs still suggest redevelopment of
another cluster of thunderstorms/mesoscale convective system (MCS)
early to mid evening across Western/Central OK as lobe of
vorticity spins up along/ahead of another shortwave trough that
will move across the Southern/Central Plains tonight. With the
boundary layer for much of Eastern OK and Northwest AR being
somewhat stable and worked over behind this morning’s/early
afternoon convection, there is still some uncertainty how this
convection will evolve this evening. Have maintained NBM PoPs,
with some minor adjustments, for tonight and into Tuesday morning.
PoPs may need to be further adjusted as the event unfolds this
evening. With the assumption of another MCS spawning this evening,
damaging wind gusts and very heavy rainfall will be the main
concerns (with large hail up to 1 inch in diameter being
secondary) as the MCS advances southeastward into Southeast OK
late this evening and into the overnight hours. North of this
feature, generally along and north of I-40 in Northeast OK, the
shortwave trough is also expected to help produce isolated to
scattered showers and thunderstorms that will gradually progress
eastward into West-Central/Northwest AR after midnight. A few of
these particular thunderstorms may be strong and/or marginally
severe as well, with heavy rainfall, damaging wind gusts and large
hail being the primary hazards. Hi-res model data have the MCS
moving out of the forecast area by or just after sunrise Tuesday.
Will continue to monitor and adjust the forecast as needed.

.LONG TERM...
(Tuesday through Monday)
Issued at 205 PM CDT Mon Jun 3 2024

Showers and thunderstorms should be ongoing across parts of
Southeast OK and into Northwestern AR at daybreak Tuesday morning,
which should continue to move eastward/southeastward as the
morning progresses. The “troughiness” mid/upper-level pattern will
persist through the daytime on Tuesday, though the majority of
Tuesday is expected to be mostly dry for most locations. However,
yet another mid-level shortwave trough will arrive over the region
Tuesday evening/night into Wednesday morning as a surface frontal
boundary also approaches from the northwest. Another MCS is
forecast to develop near/ahead of the approaching front as a
result. There is still a lot of uncertainty with how this scenario
will evolve and unfold, timing and locations included. Main
hazards with this scenario would be damaging wind gusts and large
hail.

Much more benign and stable conditions arrive by Wednesday
afternoon as northwest flow pattern aloft commences and dominates
through the middle part of the week. Wednesday morning’s cold
front may meander/stall across the forecast area during the
daytime Wednesday, perhaps even lifting northward Wednesday
evening/night. By Thursday morning, a stronger surge of surface
high pressure from the Northern Plains is expected to push the
cold front through the entire forecast area, exiting sometime
Thursday night/Friday morning. A few ensemble members and medium-
range deterministic models have isolated showers/thunderstorms
developing along the cold front as it advances southward Thursday
afternoon/evening, but with low confidence in this occurring,
decided to leave the mention of precipitation out of the forecast
for now.

Mid/upper-level ridging will build over West TX/East NM by
Friday, with northwest flow continuing over our region. A few mid-
level perturbations will have to be monitored in later forecasts
for additional thunderstorm complexes rolling through the
northwest flow aloft this upcoming weekend. Otherwise, near
seasonal to slightly above seasonal temperatures are expected this
weekend. Beyond this weekend, forecast uncertainty drastically
increases and forecast confidence is low.

This Outlook is for Northwest and West Central Arkansas as well as
much of Eastern Oklahoma.

.DAY ONE...This Afternoon and Tonight.

SEVERE THUNDERSTORM.
	RISK...Elevated.
	AREA...Southeast Oklahoma and Northwest Arkansas.
	ONSET...Ongoing.

FLASH FLOOD.
	RISK...Limited.
	AREA...Eastern Oklahoma and West Central Arkansas.
	ONSET...Ongoing.

HEAVY RAIN.
	RISK...Elevated.
	AREA...Eastern Oklahoma and Northwest Arkansas.
	ONSET...Ongoing.

DISCUSSION...
A complex of showers and thunderstorms will continue to move east
and southeast over eastern Oklahoma and northwest Arkansas
this afternoon. Severe weather potentials remain with
these storms across southeast Oklahoma and northwest Arkansas.
Damaging winds are the primary threat with a secondary threat of
large hail. Locally heavy rainfall will also be a concern with the
storms today, which may result in some localized flooding issues.
Majority of these storms should be exiting by late this afternoon.

Additional storm chances return overnight tonight for eastern
Oklahoma and northwest Arkansas, with another potential storm
complex developing and moving through the region. Limited severe
potentials along with additional locally heavy rainfall would be
capable with any storm development overnight.

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

.DAYS TWO THROUGH SEVEN...Tuesday through Sunday.
TUESDAY...Severe Thunderstorm Potential...Heavy Rain Potential.
WEDNESDAY...Thunderstorm Potential.
THURSDAY...No Hazards.
FRIDAY...Thunderstorm Potential.
SATURDAY...Thunderstorm Potential...Heavy Rain Potential.
SUNDAY...Thunderstorm Potential.

EXTENDED DISCUSSION...
Another round of thunderstorms is expected Tuesday evening and
overnight as a weak cold front moves into the area from the north.
Some of these storms will likely be severe, and locally heavy
rainfall will also be possible. Thunderstorm chances will return
by Friday night through the weekend as storms that develop in the
high plains each afternoon move southeast towards our area each
night.
