Area Forecast Discussion National Weather Service Tulsa OK 623 AM CDT FRI JUL 1 2016 .AVIATION... CONCERNING TAF SITES KTUL/KRVS/KBVO/KMLC/KXNA/KFYV/KFSM/KROG. Scattered showers and thunderstorms will spread east and southeast across parts of northeast Oklahoma this morning and eventually into northwest Arkansas. Mainly VFR conditions are expected...but could see brief MVFR conditions in the heavier downpours. && .PREV DISCUSSION... /Issued 346 AM CDT FRI JUL 1 2016/ DISCUSSION... Diffuse surface boundary lies across northeast OK and northwest AR early this morning, with isolated convection beginning to break out north of the boundary. Short-range model guidance remains consistent in breaking out additional showers and thunderstorms within the frontal zone this morning across mainly northeast OK, potentially aided by a developing MCV associated with widespread convection across northwest OK. Eventually will see chances spread into northwest AR by this afternoon. Resultant cloud cover will keep temps several degrees below what we have seen recently. Boundary will lift north tonight and Saturday with any chances of storms retreating to near the Kansas border. Hotter temps will result Saturday with most areas remaining precip free through the day before a more substantial mid level shortwave moves out of the Rockies and pushes boundary back into the area Saturday night. Showers and thunderstorms will spread across northern areas Saturday night into Sunday with another brief cool down expected. Frontal boundary will begin to wash out early next week as mid level heights begin to rise. Hot weather will return with any thunderstorm chances shifting to the north. Some areas will likely see temps near 100 by the later half of the week. && .PRELIMINARY POINT TEMPS/POPS...
