Updated at 610 AM CDT Mon May 4 2026 - Gusty south winds and warm temperatures continue Monday. - Thunderstorm chances return by Monday evening through Tuesday night. Some severe weather potential will exist Monday night and Tuesday. - Below normal temperatures briefly return mid-week. && .SHORT TERM... (Through Monday) Issued at 1135 PM CDT Sun May 3 2026 Gusty south winds will continue Monday, along with above normal temperatures. Afternoon highs will generally be in the upper 70s to lower 80s despite increasing high level cloudiness. Dew points will also steadily increase as low level moisture increases during the day. && .LONG TERM... (Monday Night through Sunday) Issued at 1135 PM CDT Sun May 3 2026 Shower and thunderstorm chances increase Monday evening into early Tuesday, with the best chances across far northeast Oklahoma where elevated convection may develop. If storms do occur here, elevated instability will be sufficient for some hail. Isolated storms may also develop late Monday afternoon or evening along the dryline across southwest Oklahoma, with some potential for these storms to move into parts of southeast Oklahoma by late Monday evening as they weaken. A strong cold front will move across the area late Monday night and Tuesday, with additional shower and storm development possible near the boundary, especially late Tuesday afternoon and evening from far southeast Oklahoma into western Arkansas. This will be the most likely location for a severe storm Tuesday. Additional elevated showers and storms may develop north of the boundary and persist into Wednesday before ending. Much colder temperatures will prevail north of the frontal boundary Tuesday and Wednesday, followed by a warming trend beginning Thursday. Temperatures will warm back above normal by Friday into next weekend. Rain chances will return next weekend, with a hint at MCS potential at that time with west to northwest upper level flow continuing. && .AVIATION... (12Z TAFS) Issued at 617 AM CDT Mon May 4 2026 VFR conditions will prevail with gusty south winds today. By this evening, the consensus of the CAMs is to develop isolated storms off the dryline and move them into eastern OK this evening. Inserted prob30 groups at these TAF sites for the evening hours to cover. Guidance also has storms in the vicinity of NW AR after midnight tonight and have inserted prob30s to cover potential there. Confidence in how this evolves was not great enough to go higher than prob30 mention for now. MVFR cigs are expected behind a front by 12Z at KBVO, and ahead of the front across NW AR.
