What happened

The episode as NWS OUN wrote it up.

A rather nebulous upper air pattern existed across the Southern Plains on the 30th, with 30-40 knots of quasi-zonal flow at 500 mb. However, plentiful solar insolation/surface heating in the vicinity of a dryline fostered widely scattered thunderstorm development by the late afternoon. Strong instability and sufficient organizing wind shear lead to a few of these storms displaying supercellular characteristics and producing reports of large hail initially, owing to steep lapse rates and weak low-level shear (among other factors already mentioned). By the mid-evening, as low-level shear and storm-scale interactions began to increase, a few tornadoes occurred across portions of south-central into southwest Oklahoma. The most significant of these was an EF-1 tornado near the community of Hollister (Tillman County).

What forecasters said that day

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

.SHORT TERM...
(This evening through Wednesday night)
Issued at 300 PM CDT Tue Apr 30 2024

Daytime heating this afternoon will support the chance for isolated
to widely scattered thunderstorms along a diffuse dryline as
convective inhibition weakens across western Oklahoma. Effective
bulk shear will be modest (~35 knots) for supercells. The expected
hazards will be damaging wind gusts and hail; however, if any
supercell can sustain themselves into the evening, there will be a
short window of opportunity for a low tornado threat as the low-
level jet strengthens with an attendant increase in low-level
storm relative helicity. Thunderstorms should weaken with the loss
of daytime heating as convective inhibition strengthens.

Additional thunderstorms are expected to develop across Kansas in
association with a cold front, which will likely move southward into
north central Oklahoma tonight. Warm air advection associated
with a low-level jet may result in continued development in this
zone. Given the heavy rainfall they experienced with the last
event, we opted to issue a Flood Watch for north central Oklahoma.

For tomorrow, the uncertainty is on how far southwest the outflow
boundary from the morning thunderstorms will progress. This
boundary may serve as a focus for redevelopment tomorrow
afternoon. Another scenario is that convection may continue to
move to the southwest through the day and never fully dissipate.
In addition, the dryline should retreat farther to the west, into
the Texas and Oklahoma panhandles. Both of these boundaries (and
any associated intersection) will result in a chance for
thunderstorms tomorrow afternoon. Strong to severe thunderstorms
will be possible.

Tomorrow night, there is evidence that any ongoing thunderstorms
may consolidate into one or two complexes that will move across
the area.

.LONG TERM...
(Thursday through next Monday)
Issued at 300 PM CDT Tue Apr 30 2024

There remains uncertainty on where the cold front will be
Thursday as it will depend on what happens Wednesday night. The
cold front will likely get another southward push on Thursday with
another chance of showers and thunderstorms.

The aforementioned cold front will likely lift back to the north
on Friday with persistent southwest flow into the upcoming
weekend. As a result, there will be continued periods of showers
and thunderstorms. Flooding will likely become a hazard in some
locations given the recent rainfall across the area.

.AVIATION...
(18Z TAFS)
Issued at 1218 PM CDT Tue Apr 30 2024

VFR and MVFR ceilings are expected this TAF period. A frontal
boundary is expected to move into parts of northern OK overnight
which will cause winds in this area to shift towards the E and NE.
Isolated/widely scattered storms are possible late
afternoon/evening but chances too low for any particular TAF
sites. However, current thoughts are highest chances would be
SW OK/western north TX and in N OK. More widespread storms will be
possible overnight into Wednesday morning in north
central/northern OK with the boundary.

.Heavy rainfall...
Heavy rainfall could lead to localized flooding this evening and
overnight across northern Oklahoma.

Elevated to near critical fire weather conditions are possible
over a small portion of northwest Oklahoma this afternoon due to
warm temperatures, breezy southwest winds, and low RH values as
the dryline advances across the area.

.DAYS TWO THROUGH SEVEN...Wednesday through Monday...

.Thunderstorms...
Thunderstorm chances increase Wednesday and Thursday with severe
weather possible both days. Thunderstorms are also possible

Path length: 6.4 mi

Property damage: $50,000
Reported by: NWS Storm Survey
Coordinates: 34.362, -98.832

This tornado was first observed by a storm chaser at 932 pm CDT and likely formed near County Road E1830 just east of County Road N2320. Over the next 40 minutes, the tornado meandered slowly eastward along E1830 Road then turned northeast reaching near N2360 Road and E1820 Road. The tornado then turned and moved west-northwest along EW1820 Road finally dissipating near N2340 Road. The tornado occurred in a very rural area of Tillman County, although two farm homes were damaged near the easternmost point of the tornado path. A few barns were also damaged, otherwise the damage was primarily to trees and a few power poles.

Although the damage is rated as EF1, velocity data from the nearby KFDR radar gives strong indication that the tornado may have been much stronger than observed damage would indicate. The maximum observed rotational velocity from KFDR reached 114 knots.

A strong anticyclonic tornado developed between Loveland and Grandfield near the intersection of county roads E1890 and N2370 Roads. Trees were snapped near the beginning of the path, but no other damage was observed or accessible in this very rural area of Tillman County and the remainder of the path is estimated from differences in NDVI satellite imagery. As with the tornado northeast of Hollister, velocity data from nearby KFDR radar indicates that this tornado was likely stronger than the observed damage indicates with the rotational velocity observed from KFDR up to 71 knots.
