Tornadoes and Flash Flooding in Oklahoma, May 4 to 12, 2022

May 4 to 12, 2022 · NWS TSA · 43 events in 13 counties and zones

A strong storm system slowly moved from the central Rockies into the Southern and Central Plains on the 4th and 5th. The associated surface frontal boundary located over northern Texas early on the 4th moved north into central Oklahoma as a warm front by the late afternoon, and then near the Kansas border on the 5th ahead of a cold front.

What happened

The episode as NWS TSA wrote it up.

A strong storm system slowly moved from the central Rockies into the Southern and Central Plains on the 4th and 5th. The associated surface frontal boundary located over northern Texas early on the 4th moved north into central Oklahoma as a warm front by the late afternoon, and then near the Kansas border on the 5th ahead of a cold front. The first round of thunderstorms developed over eastern Oklahoma during the morning hours of the 4th. These thunderstorms were rooted above a shallow, stable layer of air near the ground, and the strongest storms produced hail up to penny size. Another round of thunderstorms developed during the early evening hours. The storms over northeastern Oklahoma were rooted above a shallow, stable layer of air near the ground, and produced large hail up to half dollar size. The thunderstorms that developed over east central Oklahoma near the warm front were rooted near the ground. These storms were able to become supercells, given the moderately strong instability that had developed during the afternoon, combined with strong deep layer wind shear. The low-level wind shear had become strong near the warm front itself, which supported the development of a few tornadoes. Thunderstorms continued to develop across the area during the overnight hours of the 4th and early morning hours of the 5th, which resulted in locally heavy rainfall and flash flooding. The final round of thunderstorms developed during the early afternoon of the 5th, with the strongest storms producing hail up to quarter size.

Widespread, heavy rainfall during this period resulted in three to eight inches of rain across much of east central and northeastern Oklahoma, with areas of up to twelve inches. In addition to the flash flooding, this widespread, heavy rainfall resulted in major flooding along portions of the Neosho River, the Illinois River, the Deep Fork River, and Baron Fork Creek, as well as moderate flooding along portions of Polecat Creek, and the Poteau River.

.SHORT TERM...
(Today and Tonight)
Issued at 345 AM CDT Wed May 4 2022

Warm front currently aligned south of the Interstate 20 corridor
through central TX and arcing northeastward toward the Arklatex
region. Broad low level jet and associated warm advection is
ongoing supporting recent development of isolated showers across
the local region. This trend will continue through early morning
while the warm front steadily lifts northward. Guidance widely varies
in the extent of convection through early afternoon and confidence
is low in the coverage of any stronger storms / heavier rains
during this time.
A notable and more likely uptick in convective coverage is
expected to begin by mid afternoon and become widespread through
the overnight hours. The warm front is likely to advance into SE
OK and possibly north of Interstate 40 through E OK by late
afternoon. Much of the northward advance will be determined by the
extent of morning convection. Storms will develop well west of the
region along the dryline by mid afternoon, however additional
development eastward through the warm sector is also possible. The
moisture rich warm sector airmass characterized by mean mixing
ratios of 12-14g/kg will have minimal remaining inhibition by mid
afternoon while the influence from the subtropical jet streak
rotating northward ahead of the approaching upper low fosters lift
across the warm sector. Should these further eastward storms
develop, a NE storm motion would track into E OK and interact
with the lifting warm front to support a risk of significant
severe weather. The further westward storm development is likely
to grow upscale as it approaches the forecast area during the
evening and likely bring an increase in severe weather coverage as
it expands across the forecast area. Renewed convection may also
develop overnight along the advancing cold front and accelerate
eastward through any yet overturned instability. This prolonged
convective period will yield heavy rainfall and localized
excessive and potentially dangerous rainfall totals through the
overnight hours.

.LONG TERM...
(Thursday through Tuesday)
Issued at 345 AM CDT Wed May 4 2022

Storms are likely to be ongoing early Thursday well ahead of the
approaching cold front. The degree of destabilization ahead of the
front by afternoon remains uncertain given the early day storms,
however any additional redevelopment by early afternoon along the
front would pose a continued risk of severe weather before the
front pushes east of the forecast area by late afternoon.

Cooler and drier weather Friday before return flow begins
Saturday. A stark airmass change will occur over the weekend with
both temperatures and dewpoints rising well above recent levels
and more typical of early summer. This will occur as the pattern
aloft becomes highly amplified with a sharp dryline becoming
established west of the area and likely focusing the bulk of any
storm coverage through mid next week west and northward.

(12Z TAFS)
Issued at 619 AM CDT Wed May 4 2022

MVFR cigs will prevail through the period, however cigs/vsbys
will lower to IFR at times in areas of thunder that will become
more widespread later this afternoon and evening. TSRA will impact
all sites by 06z and continue through the remainder of the
period with MVFR/IFR cigs/vsbys.

...Severe Weather And Flooding Risks Today Through Thursday...

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

.DAY ONE...Today and Tonight.
TORNADO.
	RISK...Elevated.
	AREA...Primarily Eastern Oklahoma.
	ONSET...After 3 PM.

SEVERE THUNDERSTORM.
	RISK...Significant.
	AREA...Eastern Oklahoma and Northwest Arkansas.
	ONSET...Late Morning.

	AREA AT GREATEST RISK...Eastern Oklahoma.

FLASH FLOOD.
	RISK...Elevated.
	AREA...Eastern Oklahoma and Northwest Arkansas.
	ONSET...Late Afternoon.

DISCUSSION...
Thunderstorms will develop this morning with a limited risk
of severe weather and heavy rainfall primarily across
northeast Oklahoma. A steady increase in storm coverage is
expected beginning mid afternoon with storms becoming widespread
this evening through the overnight hours. A focus for
severe weather will be a warm front lifting northward into
the region. Conditions along and south of the warm front
will be highly supportive of severe weather later this
afternoon and overnight. Any isolated storms that develop
and move into this environment will pose a risk of
significant severe weather including tornadoes. A larger
area of storms is likely to spread into the region by
late evening with a risk of locally damaging winds and
possibly tornadoes continuing into the overnight hours.
The prolonged period of storms from late afternoon
through overnight will raise the potential for dangerous
flooding.

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

.DAYS TWO THROUGH SEVEN...Thursday through Tuesday.
THURSDAY...Severe Thunderstorm and Heavy Rain Potential.
FRIDAY through SUNDAY...No Hazards.
MONDAY...High Wind Potential.
TUESDAY...Thunderstorm Potential...High Wind Potential.

EXTENDED DISCUSSION...
Severe weather could be ongoing early Thursday morning
and storms may also redevelop Thursday afternoon along
an advancing cold front. While uncertainty remains in
the coverage of storms by Thursday afternoon, any storms
which do develop would pose a risk of severe weather.

Dry and mild weather prevails Friday before a notable
change occurs over the weekend. Hot and humid conditions
will develop Sunday and persist through early next week.
The early season heat often raises potential for heat
stress for any outdoor activities.

The tornado enlarged and turned more northeast as it approached the E1130 Road, where the tree damage increased with numerous uprooted and snapped trees through where it crossed Highway 48 with a damage path width of about 3/4 of a mile wide. Outbuildings were also damaged. A gas station received minor damage where it crossed I-40. The tornado continued north-northeast producing light tree damage across the E1100 Road and Highway 56, then dissipated before it reached Highway 62 northwest of Okemah.
