Locally heavy rains possible through Friday night.

.AVIATION... (00Z TAFS) Issued at 635 PM CDT Thu Sep 4 2025
VFR conditions should prevail through the evening and most of the overnight periods. Scattered showers and thunderstorms are expected to increase in coverage across NE OK during the early morning hours, possibly impacting NE OK terminals through most of the morning with showers and the occasional rumble of thunder. The better rain chances should shift north by the afternoon, so have left out of mention for now, but showers could linger in the area through much of the day behind the passage of a cold front. Lighter showers or mist could also affect NW AR sites during the morning... have opted to mention the chance for some mist and somewhat reduced vsby to cover this threat. Cigs should mostly remain VFR, but some signal for a few MVFR cigs are there, especially within any heavier showers or storms. With the frontal passage will also come breezy northerly winds with gusts in the 20-25 knot range during the daylight hours tomorrow across NE OK and NW AR.
