.SHORT TERM...
(The rest of tonight)
Issued at 843 PM CDT Thu May 2 2024

Scattered showers and storms have developed this evening
across northeast Oklahoma in the vicinity of a cold front
that currently stretches from near Miami to near Oilton.
Scattered showers and storms are expected to persist through
much of the night as the front pushes to the south and a
mid-level shortwave moves across southeast Oklahoma. A few
storms could become strong to marginally severe with large hail
the main concern. Have updated pops slightly for the remainder of
tonight. Otherwise, current forecast for tonight is on track.

&&

.LONG TERM...
(Friday through Thursday)
Issued at 111 PM CDT Thu May 2 2024

The unsettled pattern will remain through the rest of the period,
with near daily shower and storm chances into the next week. some
severe potential will exists across the region, but particulars
will depend on the evolution of previous day's convection so the
details will be ironed out with future forecasts.

Friday looks to be the most tame day of the forecast period, with
most locations staying dry as a dryer airmass filters in behind
the cold front this evening. Lingering showers and storms will
remain possible across southeast Oklahoma and into the terrain of
western Arkansas where the front will stall through the day
Friday. Moisture will begin to return Friday evening as the weak
boundary moves back northward. Another complex of showers and
storms forming across western Kansas Friday evening could make its
way into northeast Oklahoma Saturday morning in a decaying state,
but periods of locally heavy rainfall will be possible,
especially across northeast Oklahoma Saturday morning. Another
disturbance is progged to advance northeastward across the
Southern Plains Saturday night into Sunday, bringing widespread
rain chances to the area through much of the day Sunday. Showers
and storms should increase Sunday morning across eastern Oklahoma
and move eastward into western Arkansas Sunday afternoon. Again,
severe potential will be low given the background environment but
anytime there are storms in May there is potential for some
embedded strong to severe storms.

As we head into next week, strong zonal flow aloft develops as a
lead shortwave trough ejects out of the Rockies and into the
Central and Northern Plains. At the surface, a frontal boundary
will then drop southeastward and likely set up camp somewhere
across the Southern or Central Plains while a dryline extends
southward across western to central Oklahoma and into Texas.
Periodic ripples in the flow aloft are forecast to advance across
the Plains states throughout the rest of the week. This, combined
with the strong flow aloft and continued low level moisture
advection into the region will create a scenario with at least
daily isolated to scattered storm development within the warm
sector. The large instability and persistent strong deep layer
shear would support severe weather with any storms that develop.
Mid level capping will limit the coverage of storms through the
first part of the week, likely confined to areas of increased
synoptic forcing where any speed max can increase convergence
along the dryline. More widespread, organized severe potential
will be probable during this time, but those details will come in
the coming days with better agreement on timing and location of
the various vort maxes that track through the region.
Nevertheless, be prepared for another round of springtime storms
across the Plains next week.

.AVIATION...
(00Z TAFS)
Issued at 627 PM CDT Thu May 2 2024

Cold front moving into northeast Oklahoma early this evening,
currently located near a Pawnee/Welch line. Scattered thunderstorms
will continue this evening ahead of boundary with a modestly
unstable air-mass in place. PWATs around 1.4 inches will produce
brief heavy rain, likely reducing visibilities below 1 mile in
the stronger storms. Front stalls late tonight into Friday morning
with lower IFR ceilings developing at most locations, including
the potential for patchy dense fog in NW AR. Ceiling heights will
slowly rise through day Friday with VFR conditions forecast by mid
afternoon.

Organized severe weather is not expected, but a few of these
storms could become severe briefly with hail and wind the main
threats. Locally heavy rainfall from these storms could lead to
flash flooding.

A complex of storms could organize tonight and move east across
southern Oklahoma. There is a limited risk of severe wind from
these storms if they were to move into southeast Oklahoma before
weakening.

SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT...
Local Spotter Activation May Be Needed.

.DAYS TWO THROUGH SEVEN...Friday through Wednesday.
FRIDAY...Thunderstorm Potential.
SATURDAY THROUGH WEDNESDAY...Thunderstorm Potential...Heavy Rain Potential.

EXTENDED DISCUSSION...
The unsettled weather pattern continues through the middle of next

significant severe weather will be from Monday onward as the flow
aloft strengthens. The potential for flash flooding will exist
with any pockets of locally heavy rainfall that occurs, especially
this weekend.
