Saturday Night: Mostly cloudy, warm, and humid. Overnight lows will only cool to the upper 60s to low 70s. Areas of patchy fog may form in some areas as the air cools during the night. Isolated rain is also possible during the overnight. Winds will be out of the SE between 5-15 mph.

Sunday: Widespread severe weather will develop in Central Oklahoma and Central Kansas in response to strong upper level energy and a dryline advancing east. These storms will be supercells which could contain large hail, damaging wind, flooding rains, and tornadoes. The storms will move east and eventually merge into a complex that will affect NE Oklahoma and potentially NWA Sunday night. Sunday will be hot in humid again with highs in the 80s and 90s. Winds will increase out of the south between 15-25mph.  A few isolated showers and storms are possible during the day before the main threat comes in overnight.

Monday/Tuesday Severe Weather: The leftover boundaries from the Sunday night's storms will continue in the area on Monday with peak daytime heating and another upper level jet stream disturbance... another round of strong to severe storms is possible including strong storms capable of tornadoes in Northwest Arkansas and the Fort Smith area. The timing would be evening into the overnight. Severe storms will also be possible on Tuesday before the threat ends as cooler and drier air moves in around midweek.
