NWS Norman, OK wrote its last area forecast discussion before the first event at Jun 22, 1:19 AM CST, 4 hours 16 minutes earlier.
Area Forecast Discussion National Weather Service Norman OK 219 AM CDT Fri Jun 22 2018 .DISCUSSION... Main concerns will be with MCS overnight tonight and then with position of residual boundary and severe weather potential Saturday. South winds will increase by late in the day in response to developing surface low across the high plains. To the northeast of this surface low, showers and thunderstorms are expected to develop this afternoon. This activity is then expected to develop into a complex of storms, which will then move south and east toward Oklahoma this evening. Models are indicating a quick moving MCS will move into northwest Oklahoma early this evening and then toward central Oklahoma by late evening and then potentially exiting southeast Oklahoma before sunrise Saturday morning. Main impacts will be very strong, damaging straight-line winds as well as very heavy rainfall as PWs look to be in excess of 1.5 to 2 inches. Although overall flood threat may be minimized with expected speed of the system. Next round of storms is expected to develop Saturday afternoon near boundary left behind from overnight MCS. Where exactly this might be will be hard to determine beforehand. However, most likely location would be somewhere between I-40 and the Red river, with central into eastern parts of Oklahoma having the highest chances. Very unstable airmass is likely to be in place with models showing favorable wind fields for supercell thunderstorms. Any storm that remains in proximity to the boundary would have some tornado threat as well as very large hail and damaging winds. Again, heavy rainfall will also be a concern. A larger-scale trough then approaches the plains by late Sunday into Monday. Initially, main impacts look to remain to our north. However, as trough move east and northeast through the plains, surface front may make a push south into area, providing another chance for storms by Monday night. Upper ridge may try to build out into the plains by latter part of next week reducing the rain chances and bringing in even warmer temperatures. && .PRELIMINARY POINT TEMPS/POPS...
