Hail and Damaging Winds in Oklahoma, September 19, 2023

Name: Hail and Damaging Winds in Oklahoma, September 19, 2023
Start: 2023-09-19T12:14
End: 2023-09-19T21:05
Location: Oklahoma

September 19, 2023 · NWS OUN · 48 events in 14 counties and zones

As multiple low-amplitude upper waves (embedded within broad zonal flow) traversed the Southern Plains, two rounds of convection occurred across the forecast area on the 19th. The first round, from the late morning into early afternoon, included a few reports of marginally severe hail across north-central into eastern Oklahoma, owing to relatively weak instability present during this time frame.

What happened

The episode as NWS OUN wrote it up.

By the early evening, aided by sufficient deep-layer wind shear and increasing (significant in magnitude) convective instability, multiple supercell thunderstorms initiated across southwest Oklahoma. Reports of large to very large hail and wind damage were received across the aforementioned areas. A 'left-split' (supercell) thunderstorm traveled into portions of central Oklahoma, including the southern suburbs of the Oklahoma City Metropolitan area, and produced continued reports of significant hail during the late evening time frame. Additional supercell thunderstorms developed further north across central Oklahoma during the evening as well. While a few reports of large hail were also received with these storms, greater convective inhibition limited the longevity of impact from these thunderstorms.

What forecasters said that day

The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Norman, OK wrote its last area forecast discussion before the first event at Sep 19, 11:43 AM CST, 31 minutes earlier.

...New AVIATION...

.UPDATE...
Issued at 1109 AM CDT Tue Sep 19 2023

Updated POPs for late this morning through early this evening
following both trends on radar and short-term trends in model
output. The highest POPs will be focused from south central to
east central Oklahoma, but there is still definitely enough signal
for redevelopment farther west that POPs are still warranted out
there, although convection may be more scattered.

Did not adjust the high temperature, but made adjustments to the
hourly grids as these morning clouds have slowed down the morning
warming. Still think the forecast max temps can be achieved as
skies are clearing in the west, but the hourly temps should now be
closer to representative.

.SHORT TERM...
(Today and tonight)
Issued at 359 AM CDT Tue Sep 19 2023

Showers and thunderstorms will be likely widespread across our area
in the short term, potentially becoming severe by Tuesday afternoon
with the severe risk continuing into the evening hours.  Gusty south
winds coupled with this mornings low-level jet will transport gulf-
based moisture up through the boundary layer increasing lower to mid
60s surface dewpoints up from northern Texas into Oklahoma by late
morning. Tuesdays low-level moisture advection will also sharpen up
a dryline up through west Texas into the Southern High Plains.
Meanwhile, an embedded mid-level shortwave propagating through our
nearly zonal westerlies could initiate a first round of convection
after sunrise through the morning until the low-level jet weakens by
late morning.  One to possibly two troughs developing lee of the
Colorado Rockies in our westerlies will be digging across the
Central High Plains and with the first one moving into the Southern
Plains by the afternoon. This lee trough will steepen mid-level
lapse rates resulting in rapid destabilization, with moderate 2000-
3000 J/kg of surface based CAPE to work with in the afternoon as
well as moderate instability for any elevated lifted convection.
Although 925 mb winds weaken by afternoon, ample 850 mb south-
southwest flow may provide sufficient shear to maintain storm
organization.  As a result, could see severe storms develop late in
the afternoon with peak daytime heating as the lee trough digs
through. Another areas of severe storm development by late afternoon
could be along the dryline as heating/mixing may break the cap, and
this severe convection could affect western Oklahoma and western
north Texas. The primary severe hazards late this afternoon could be
up to golf-ball size hail to perhaps slightly bigger (2-inch)
associated with the dryline convection, as well as damaging
downburst winds. Could also see heavy rainfall under some of these
storms although southeasterly storm motion may be sufficient to
inhibit any slow-moving storms or training.

Could see dryline convection ongoing during the early evening hours
as a strong low-level jet returns for the night and maintaining
storm organization overnight.  There is some model inconsistencies
overnight with the GFS & ECMWF displacing the trough into eastern
Oklahoma while the NAM slows it down with a second trough trailing
through. Certainly could see convection into the overnight hours,
but decreasing instability should lower the severe threat by early
Wednesday morning.

&&

.LONG TERM...
(Wednesday through Monday)
Issued at 359 AM CDT Tue Sep 19 2023

For Wednesday, expecting the upper trough across eastern Oklahoma to
dig eastward into the Mississippi Valley Region.  Will restrict storm
POPs east of I-35 during the afternoon although confidence is very
low so will keep POPs below 20%.  Our zonal flow aloft will
transition into a weak ridge as a large amplitude trough develops
upstream over the Western U.S. while southerly low-level winds will
maintain those 60 degree dewpoints across our area with a dryline
stretched across the the Southern High Plains.  A series of
shortwaves expelled through our weak ridging will keep storm POPs in
the forecast every day from Thursday through Sunday as ample surface
moisture will also remain in place.  The ingredients will be in
place for supercell storms developing on Thursday, but for now it
looks to be a low-end severe event.  Storm POPs will stay restricted
to the eastern half of our CWA into the weekend with a cold front
possibly coming through on Sunday bringing our temperatures back
down to seasonably average.

.AVIATION...
(18Z TAFS)
Issued at 1243 PM CDT Tue Sep 19 2023

The current area of showers and storms will mainly affect the TAF
sites near and east the Interstate 35 corridor (KPNC, KSWO, KOKC,
KOUN) with the showers/storms lingering the longest at KPNC and
KSWO. Additional development of showers and storms are expected to
develop across the west this afternoon and spread east again late
this afternoon and evening. Skies will being clearing after the
last round of convection moves through overnight. Some of the
storms could be severe with hail and strong winds.
