.SHORT TERM...
(Through tonight )
Issued at 110 PM CDT Sun Jul 13 2025

Satellite and radar obs indicate an area of low pressure aloft
over far NE OK, moving east. This area of low pressure is embedded
within a larger scale trof axis that extends from the Great Lakes
down to W TX. Satellite imagery also indicates that the deep layer
moist plume has shifted east with the trof axis, and lies from SE
OK into west-central AR. CAMs indicate potential for scattered
afternoon storms here, with locally heavy rainfall potential. The
Flood Watch has been trimmed to cover the aforementioned area thru
00Z. At this time, there are no plans to extend the watch, and
will let the evening shift reevaluate. After 00z, the better
chance for storms and heavy rainfall looks to shift just to the
south and east of the forecast area, along with the deep layer
moist axis.

Some clearing is forecast across parts of NE OK and possibly NW AR
toward daybreak Monday. This could result in some areas of patchy
fog.

(Tomorrow through Sunday)
Issued at 110 PM CDT Sun Jul 13 2025

CAMs have been consistent today in suggesting that an MCV will
evolve from the TX Hill Country convection and then lift northeast
into our area into Monday. Expect an increase in shower/storm
coverage and potential for locally heavy rainfall, from SE OK into
NW AR. There may also be an uptick in storm organization and
severity. After a lull on Monday night in the wake of this system,
expect widely scattered storm chances on Tuesday in the same areas
along the deep layer moist axis.

A weak front will approach from the north Wednesday night into
Thursday, bringing at least low chances for storms across NE OK
and NW AR.

Mid-level ridging is expected to build over the region by the end
of the week, decreasing storm chances and increasing the heat.
Early indications are for mainly hot and dry weather for weekend
activities next weekend. There are still some credible scenarios
laid out in the ensemble clusters to suggest that the ridge may
not stay parked over our area for long and may continue to
retrograde back to the Southwest. Time will tell.

.AVIATION...
(18Z TAFS)
Issued at 1222 PM CDT Sun Jul 13 2025

Spotty showers with some low chance for thunder will persist
through the afternoon and into the evening across the region,
gradually shifting eastward with time. MVFR cigs should gradually
lift some across NE OK this afternoon as more sunshine enters the
area, while cigs will likely hold over NW AR for longer. Showers
should move out during the evening hours though some spotty shower
chances will continue across NW AR overnight. Calm winds and good
moisture around could also lead to some patchy fog development
early tomorrow morning for most sites, as well as a return to MVFR
cigs across much of the region. Winds will generally remain light,
becoming more easterly and southeasterly by tomorrow.
