.DISCUSSION...
Issued at 1146 AM CDT Sat Apr 25 2026

Recent hi-res model guidance has the main round of convective
initiation occurring along an OK warm front this evening,
northwest of McCurtain Co, OK. These storms are expected to move
southeastward into the Ark-La-Tx this evening and continue through
the overnight hours. An increasingly unstable environment will be
building this afternoon, which increases the concern for severe
weather impacts, especially in our northwest zones. Large hail
(possibly exceeding 3 inches), damaging wind gusts, and some
strong tornadoes will all be possible for the region. SPC's
outlook highlights our northwestern zones as being the highest
risk for severe hazards due to the favorable environment and the
storm mode leaning toward supercells. The storms are expected to
morph into more of a QLCS as it moves into Deep East TX, northwest
LA, and southern AR later in the night with the loss of daytime
heating. A marginal risk still exists for much of these areas due
to the risk of severe wind gusts that this line could still be
capable of. Due to this event occurring in the evening and
overnight hours, be sure you have multiple ways to receive weather
information and be woken up, if necessary.

There may still be some lingering convection from Saturday night
that bleeds into Sunday morning and clear by midday. The sfc
southerly flow that has been funneling in moisture over recent
days will continue to help keep us warm, with many places seeing
afternoon highs in the mid to upper 80s for the first half of the
work week.

A continuously active pattern will keep rain chances in the
forecast through the end of the week. SPC has a portion of the
forecast area included in 3 of the next 4 outlooks, highlighting
the potential for more severe weather to be included with the
additional rainfall. More detail will come with future forecasts,
but expect a warm and rainy next few days. The added rain will
hopefully work to help the drought conditions across the region
and bring high temperatures back into the 70s by the end of the
week.
