KEY MESSAGES

Updated at 1242 AM CDT Tue Apr 28 2026

- Another round of thunderstorms and severe weather is expected Tuesday.

- A cold front will usher in cooler and drier air Tuesday night, marking the beginning of an extended break from severe weather that is expected to last into the first part of May.

- A storm system is forecast to track east across Texas during the latter part of the week, increasing rain chances across the region. Locally heavy rainfall is possible across the south.

SHORT TERM

(Through Tuesday) Issued at 1127 PM CDT Mon Apr 27 2026

A cold front is currently advancing south across northwest Arkansas and southeast Oklahoma. A few storms have developed along and ahead of it, mainly to the east of the forecast area. With no new convective attempts evident on IR imagery, the severe thunderstorm watch was cancelled early. The front is expected to settle down into the lower Ark River Valley and SE OK by Tuesday morning.

Thunderstorm chances increase Tuesday morning as warm advection increases ahead of the approaching wave currently near Las Vegas. Storm coverage and severe potential will increase through the day. The front will lift north into SE OK and perhaps west-central AR as a weak frontal wave of low pressure slides along it during the day in response to the passing wave. Storms that get going near and south of the boundary will have the best chance of producing higher- end severe weather. Low level shear is sufficient for a supercell tornado threat, especially near the boundary, and this threat could start earlier in the day than usual. Otherwise, large hail and locally damaging wind will be the primary severe threats. CAMs suggest that the storms will move east and south of the region by early evening, in tandem with the now southward progression of the cold front in the wake of the passing frontal wave.

LONG TERM

(Tuesday Night through Monday) Issued at 1127 PM CDT Mon Apr 27 2026

Cooler and drier air will filter into the region Tuesday night into Wednesday, starting a period of below average temperatures that will last for the remainder of the week. Rain chances will increase toward the latter part of the week as an upper level system tracks east across Texas. With the warm and unstable air shoved well to the south, storm chances will be minimal at best. Locally heavy rainfall will be possible down near the Red River before the system moves away by the start of the weekend. A weak system will bring low rain chances again by the start of the next work week. With broad upper troughing over the eastern CONUS and surface ridging predominant over the south-central CONUS, we are looking at an extended period without severe weather that will last into much of the first week of May.

AVIATION

(06Z TAFS) Issued at 1245 AM CDT Tue Apr 28 2026

VFR conditions currently will give way to deteriorating flight conditions later this morning through the evening hours. MVFR cigs will spread into the area by early morning with increasing shower and thunderstorm chances from mid morning through late afternoon. Best chances will be across SE OK into NW AR sites. Multiple rounds of showers and storms will be possible. A cold front will finally push through the area later this evening with improving conditions into the overnight period, especially across E OK sites.
