.DISCUSSION...
Issued at 141 AM CDT Fri May 15 2026

Quiet conditions are ongoing across the CWA early this Fri
morning...with some light SRLY winds already noted. These SRLY winds
will increase into this afternoon as the pressure gradient tightens.
Temps will warm further from Thu as a result...even as some
increased cloud cover develops. This increased cloud cover will be
result of a weak upper wave passing over NRN sections of the state
into the afternoon hrs. This upper wave may also trigger some
isolated/widely scattered convection...with some low end POPs
mentioned again today as a result over WRN/NRN sections.

A similar situation may occur again for Sat as well...with SRLY SFC
flow continuing...and a weak upper wave passing over the AR/MO border
before the midday timeframe. Flow aloft will increase from the SW on
Sun...with SRLY/SERLY SFC flow increasing further. Most of the upper
energy looks to remain west of AR on Sun into Sun night...so have
dropped POPs to just slight chance across WRN sections with no
significant forcing mechanisms expected.

A more unsettled pattern will exist for the work week next week.
Upper level energy will attempt to move close to AR starting
Mon...but the cold front will hold off until mainly Tue and Wed.
This front will drop south into the state slowing as it drops south
and becomes parallel to the upper flow. Additional upper waves look
to pass overhead...keeping chances for convection in the forecast
nearly every day next week. While this setup tends to result in
areas of heavy rainfall with multiple rounds of convection
possible...uncertainty does exist on how far SE the front
drops...and the upper energy moves. Given the ongoing drought
conditions...a bit hesitant to get into the details regarding how
much rainfall may occur. This will be ironed out over the next few
days...and hopefully many areas can see additional beneficial
rainfall.

Will also need to at least mention some potential for seeing strong
to SVR convection with the more active pattern as well. Given the
mid/late May time-frame...deep moisture return...and stout upper
level flow...a threat for seeing SVR convection may exist.
However...details on timing of upper waves and other uncertainties
will need figured out in the coming days on any SVR threat potential
next week.
