Area Forecast Discussion National Weather Service Tulsa OK 254 PM CDT Mon Aug 14 2017 .DISCUSSION... Remains of late night MCS have pushed in AR with a lingering band of convection noted across parts of eastern OK. Old frontal boundary to our south will lift north tonight and become diffuse although still may see widely scattered overnight convection in the very moist atmosphere. Convective focus is expected to shift to our northwest later Tuesday/Tuesday night as upper flow becomes increasingly southwesterly and frontal boundary develops across the central Plains. A stronger wave is forecast to move into the Plains by Wednesday...with the frontal boundary and associated convection making a run toward the forecast area later in the day and into Wednesday night. Thursday should be mostly quiet...although the ECMWF/GFS continue to suggest potential MCS activity both Thursday and Friday nights in the northwesterly upper flow. Mid-level height rises/expansion of the ridge looks to finally set back in later in the weekend and persist well into next week...along with hot/humid/more August-like conditions. && .PRELIMINARY POINT TEMPS/POPS...
