Area forecast discussion, May 13, 6:11 PM CDT, 38 minutes before
Area Forecast Discussion National Weather Service Norman OK 611 PM CDT Mon May 13 2019 .AVIATION... 00Z TAFs... Scattered thunderstorms are expected to continue across parts of northwest and north-central Oklahoma through about 02z this evening but should mostly avoid the TAF sites with the exception of KWWR. After these storms dissipate, expect VFR conditions through the overnight and during the day tomorrow with winds mainly from the south. Ware && .PREV DISCUSSION... /issued 246 PM CDT Mon May 13 2019/ DISCUSSION... A few showers and thunderstorms have formed this afternoon along an apparent warm front in northwest Oklahoma. Additional development along and near the surface boundary seems probable (the boundary extends from near Woodward to Guthrie to east- central Oklahoma). The large dewpoint depressions in the far northwest may help a few storms produce strong winds, while marginally severe hail will be the main risk elsewhere. The storms should diminish toward sunset. The next significant weather feature is a large storm system that is expected to approach the southern Plains on Friday. This system will likely produce severe storms over parts of our forecast area both Friday and Saturday. The higher risk will be in the west on Friday, and over the entire region on Saturday. There is still a lot of difference in the details according to the models, but the overall pattern is supportive of severe storms and very heavy rain...which probably will cause additional flooding in areas that just dealt with flooding from previous storms...and will prolong flooding on those rivers still above flood stage this weekend.
