.DISCUSSION...
Issued at 1100 PM CDT Sun Jun 21 2026

A Flood Watch is in effect for portions of W, N, and C AR until 7PM
Monday. Recent CAM trends have been fairly consistently be producing
a swath of heavy rainfall along or near the I-40 corridor. Exact
placement remains variable but confidence in a 2-4" in QPF swath
with localized 6+ inch totals is growing. The highest rainfall
totals will be where convection along an outflow boundary in S MO
stalls in N AR, and an approaching MCS from KS/OK overlap.

Mesoanalysis still supports a QLCS threat in W AR. MLCAPE between
2500-3000J/kg along the AR/OK border dropping off to around 1500-
2000J/kg closer to the Little Rock metro. 0-3km SRH values between
100-150 m2/s2 as well as an increasing LLJ would support a
conditional QLCS type tornado threat in bowing segments of the line.
Point soundings show a decent layer of dry air aloft with DCAPE
values >1000J/kg values would support depending rear inflow jets
with potently damaging winds as the line enters the state.
Relatively meager lapse rates and quick storm motion likely limits
the hail risk to only the strongest of updrafts overnight. The
most likely area for impactful severe weather would be in the
Wstrn 1/3 of the state before this line loses most of its punch
and transitions to a primary hydro threat.

Areas to the S of the line on Tuesday morning have a chance for
scattered rain and t`storms. Recent CAM/HREF runs suggest that the
heavier rainfall amounts will generate a stronger cold pool boundary
making moisture recovery into S AR difficult with weak low level
flow; this should limit PoPs to areas that do not receive any
rainfall with the event Monday morning.

Through at least the midweek upper NWrly H500 flow will promote
several shortwaves and associated MCS to form off the Rockies daily.
Exact placement and impacts would have to be determined in a later
forecast as mid-range model solutions are still quite wide in scope.
Moisture return begins Tues. with return of Srthly sfc winds.
Dewpoints in the low to mid 70s will creep into SW AR and have
apparent T`s approaching 100 with an increase in deeper moisture.

High temps and apparent T`s will continue to rise into the late week
as Srthly flow continues to bring balmy conditions across the
Natural State. Long range signals continue to show a more active
pattern due to the elongated ridge across Central CONUS. Several
rounds of rain are possible through at least Friday before a sfc
high begins to build over the Red River Valley next weekend
returning drier conditions towards the end of the month.

(06Z TAFS)
Issued at 1222 AM CDT Mon Jun 22 2026

Convection is starting to initiate both over northern Arkansas
and over parts of OK. Convection will continue to fill in through
the night. Line of strong thunderstorms will make its way across
the state bringing gusty winds and reduced visibility. VFR
conditions initially will deteriorate to MVFR and possibly IFR as
the convection approaches and passes over each terminal. Winds
will average under 10 knots except in and near thunderstorms
where winds will be much gustier.
