New SHORT TERM, LONG TERM, SPOTTER INFORMATION STATEMENT
SHORT TERM
(Tuesday through Wednesday)
Issued at 1248 AM CDT Tue Apr 29 2025
Southwest flow aloft ahead of a low across the desert southwest will allow for moisture and instability to increase areawide. At the surface, a frontal boundary across central Oklahoma into northwest Arkansas will gradually shift south throughout the day serving as the focus for convection late this afternoon into this evening across portions of south Arkansas, northeast Texas and southeast Oklahoma. A few storms may be severe across McCurtain county this evening. Otherwise, temperatures today are forecast to average in the mid to upper 80s.
Showers and thunderstorms to linger into the overnight hours across the I-30 corridor northward as upper-level impulses within the overall southwest flow regime continue to interact with a surface low across central Texas and attached surface boundary extending into Oklahoma.
On Wednesday, atmosphere to continue to destabilize as the upper- low across the desert southwest begins to swing east into the Texas panhandle by midday. Forcing ahead of the approaching low will allow for an increased southerly jet across the ArkLaTex setting the stage for a potential severe weather event across mainly northeast Texas, southeast Oklahoma, and adjacent counties of southwest Arkansas at the time of peak heating late Wednesday afternoon and evening. Additionally, as the surface low across central Texas tracks northeast along the front, moisture will increase in the warm sector aiding the overall destabilization process. Supercells capable of producing large hail, damaging winds, tornadoes, and a locally heavy rainfall threat can be expected within any supercells that are capable of developing.

Conditions forecast to improve on late Wednesday evening into the overnight hours as surface and upper low translate northeast into Missouri. However, frontal boundary to remain stalled across the heart of the ArkLaTex serving as the catalyst for continued convection through Saturday. With near zonal flow aloft, not expecting much in the way of organized severe weather from late week into the early part of the weekend, but an unsettled weather pattern characterized by increased cloud cover and periods of showers and thunderstorms can be expected through Saturday.
The combination of weak upper-ridging and a surface high building across the region on Saturday afternoon will drive the frontal boundary south allowing for a drier air and cooler temperatures across the region through the weekend. Temperatures on Sunday to climb into the upper 70s to lower 80s with overnight lows on Sunday night in the upper 50s to lower 60s. /05/

For the 29/06Z TAFs, CIGs and VSBYs will continue to drop from VFR to MVFR/IFR values as low cloud decks become more widespread overnight. Areas of rainfall will be possible across far northwestern ArkLaTex airspace during the day today. Southerly winds will increase to maximum sustained speeds of 10 to 15 kts, with gusts of up to 20 kts possible.
