Area Forecast Discussion National Weather Service Tulsa OK 1151 AM CDT FRI JUL 1 2016 .AVIATION... CONCERNING TAF SITES KTUL/KRVS/KBVO/KMLC/KXNA/KFYV/KFSM/KROG. VFR conditions expected to prevail through the period, with any category reductions restricted to thunderstorm activity. Scattered thunderstorms may affect mainly the NE OK and far NW AR terminals this afternoon, with potential continuing to be covered with a VCTS mention due to areal coverage expected. Winds will shift from a northerly direction to a southerly direction by tomorrow morning. && .PREV DISCUSSION... /Issued 952 AM CDT FRI JUL 1 2016/ ..UPDATE... DISCUSSION... The early morning convection in northeast Oklahoma to the west of Highway 75 continues on its downward trend that began within the past hour or two, with generally light to occasionally moderate rain remaining. Additional thunderstorms should develop along and north of the boundary that currently stretches across east central Oklahoma and into northwest Arkansas, with a very limited potential for strong winds in the strongest storms. The experimental HRRR is handling the expected conditions fairly well to this point. Changes to the POP grids this morning have been to show a lull in the activity for the late morning hours, with a previoualy forecast upswing during the afternoon. No other significant changes have been made to the going forecast. PREV DISCUSSION... /Issued 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. TSA Watches/Warnings/Advisories... OK...None. AR...None. && .TSA Watches/Warnings/Advisories... OK...None.
