.SHORT TERM...
(Today)
Issued at 329 AM CDT Mon May 13 2024

Shower and thunderstorm activity is ongoing this morning as an
upper level wave was observed sliding east across the C Plains.
Expect showers and storms to persist as synoptic-scale ascent
remains overhead with gradually increasing instability across the
CWA through the morning hours. Storms have been strong to severe
at times across C OK and would expect at least a limited threat of
marginally severe hail/ strong wind to continue as storms
progress into E OK this morning.

The upper level wave will continue its slow eastward progression
today with reinvigorated shower/ storm potential as a weak sfc low
and associated front sweeps through this afternoon. Questions
remain regarding the impact of morning convection and how well the
atmosphere recovers this afternoon, but at least a marginal
threat of severe weather may evolve... primarily across portions
of SE OK and NW AR as the front moves through. With 35-45 kts
effective shear and 700-500mb lapse rates on the order of 6.5 to 7
C/km forecast in this area, any stronger storms may produce some
large hail/ strong winds. While the tornado threat is non-zero,
poor low-level shear/ SRH values should tend to keep the tornado
threat very low. Higher severe probs are located southeast of the
FA. Locally heavy rainfall will also be a concern, especially for
any training clusters this morning... though this threat will be
decreasing with time. Precip coverage should wane by this evening
with loss of instability.

Though there should be more sunshine today, temps will likely be
similar or slightly cooler than yesterday... generally in the mid
to upper 70s. Outside of any thunderstorm-induced gusts, max winds
should remain in the 10-20 mph range.

.LONG TERM...
(Tonight through Sunday)
Issued at 329 AM CDT Mon May 13 2024

With the trough axis passing overhead tonight, any lingering showers
and storms this evening should tend to become increasingly sparse...
with only low chances of precip overnight for far NE OK/ NW AR
zones. It is not out of question to see some showers/ isolated
thunder pop up Tuesday afternoon across NW AR as moisture wraps
around the departing system, so have maintained low PoPs here.
Although, QPF from this activity should remain quite light.

Expecting a break from precip chances Tuesday night into Wednesday
as drier air is pulled into the region. This will be short-lived,
however, as another string of upper disturbances impact the region
Wednesday night through Friday, bringing several more rounds of
precip. While this pattern doesn't look overly favorable for severe
weather, it does not take much this time of year... and at least a
limited severe threat may accompany storms during the late Wednesday-
Thursday period. Similar to yesterday and today, it appears heavy
rain potential will increase as PWATs climb to near 1.5" during this
time. WPC has included the region in a slight risk for excessive
rainfall with this activity as a result.

A cold front is projected to push into the region to finish the work
week which should bring another break in precip as the upper level
wave finally shifts east. Guidance really begins to diverge for the
weekend forecast, with some solutions suggesting a period of ridging
and dry weather... while others bring another upper low into the FA
providing another shot at showers and storms. Given these
discrepancies & uncertainty, have opted to leave NBM PoPs as they
are... which provides slight chance to chance for much of the area
Saturday & Sunday. The pattern appears to remain active as we head
into next week.

Highs will be a smidge cooler on Tuesday across far NE OK/ NW AR
under the influence of the upper low (Lower to mid 70s). Otherwise,
max temps will generally land in the upper 70s/ lower 80s through
the week, becoming noticeably warmer by the weekend in the 80s/
nearing 90 (especially if the aforementioned period of ridging
verifies). Expect lows in the 50s & 60s through the forecast period
and winds should remain tame and generally under 20 mph.

.AVIATION...
(12Z TAFS)
Issued at 607 AM CDT Mon May 13 2024

Of immediate concern is the link of thunderstorms about to reach
the NE OK terminals and expected to reach the remaining ones
through the morning hours. Expect IFR conditions as the
thunderstorms pass, with improvement to MVFR afterward. Additional
thunderstorms remain expected this afternoon, with the W AR sites
and MLC most likely to have on-station impacts. Will carry
PROB30's for such at those 5 sites, with a VCTS mention in NE OK.
VFR conditions should prevail for much of the overnight at the E
OK sites, with MVFR conditions redeveloping late in the period in
W AR.
