Area forecast discussion, Jun 15, 3:07 PM CDT, 6 hours 36 minutes before
Area Forecast Discussion National Weather Service Norman OK 307 PM CDT Sat Jun 15 2019 .DISCUSSION... Storm development is expected to continue in the high plains of eastern NM and CO and then near a dryline in the Panhandles into west TX. These storms will move towards the area moving into western portions of the fa this evening. Other storms could also develop near a boundary in northern OK late this afternoon and evening. All the storms are expected to develop into one or more thunderstorm complexes that move across portions of the area this evening into early Sunday. These storms could become severe beginning late this afternoon and continuing into the overnight hours. Initially, large hail and strong winds will be the main threats but the potential for damaging winds will increase later this evening with the potential for large hail decreasing. Heavy rain/flooding will also be a concern in some areas tonight. What happens Sunday will be impacted by what occurs later today into early Sunday. Showers/storms do appear likely Sunday afternoon/night due to a shortwave moving across OK. Storm development may also be aided by any lingering boundaries and/or MCVs from tonight's convection. Enough recovery of the airmass over the area could happen that some strong/severe storms could develop late Sunday afternoon/night. Another round of showers/storms will be possible Monday evening into early Tuesday and then again Tuesday night into early Wednesday mainly from convection developing in the high plains and then moving into the fa. However, a frontal boundary could be just south of the Red River at least on Monday which some storm development near the boundary could be possible in S portions of the fa as well. There could also be other lingering boundaries, etc in/near the fa from the previous night's convection early next week. Off and on rain chances will continue across at least portions of the fa into next weekend. Heavy rain/flooding and strong to severe storms will also remain possible next week. && .PRELIMINARY POINT TEMPS/POPS...
