NWS Norman, OK wrote its last area forecast discussion before the first event at Jul 13, 5:16 AM CST, 4 hours 44 minutes earlier.
Area Forecast Discussion National Weather Service Norman OK 616 AM CDT WED JUL 13 2016 .DISCUSSION... The 13/12Z TAF discussion is below. && .AVIATION... Expect VFR conditions to continue through the TAF period. Gusty southerly winds will prevail. Winds will veer to the southwest across northwest Oklahoma later this morning before backing back to the south this evening. Isolated showers and thunderstorms could affect KGAG and KWWR late this afternoon/evening and KPNC after midnight; however, the probability is too low to include in TAFs. Mahale && .PREV DISCUSSION... /issued 402 AM CDT WED JUL 13 2016/ DISCUSSION... Isolated showers (perhaps some thunder) will be possible this morning as some weak ascent passes by the region (seen in water vapor imagery); however, anticipate any chance to end later this morning. A few storms may develop in the Texas panhandle again late this afternoon. However, these storms will have a low chance entering western Oklahoma due to very warm mid-level/700 mb temps (>15C). Elevated fire weather will be a concern the next couple days, especially across the west where some drier air may mix eastward. Relative humidity values will be near 20% across northwest Oklahoma today and across western north Texas/southwest Oklahoma Thursday. Temperatures will also be quite hot with forecast highs in the low 100s in these areas. Currently, it appears there may be greater overlap of stronger surface winds and lower relative humidity on Thursday. An effective cold front is expected to be near the Oklahoma/Kansas border Thursday afternoon. Environmental conditions will be favorable for severe thunderstorms with MLCAPE >3500 J/kg and effective bulk shear >45 knots. Expect initial storms to have supercellular characteristics near the border; however, storms are expected to grow upscale into a mesoscale convective system. The MCS/effective cold front will likely progress southeastward Thursday night as a low-level jet intensifies. In addition to severe weather, heavy rainfall will also be a hazard. Both the GFS and NAM have precipitable waters >1.80" (>90th percentile) in northern Oklahoma Thursday evening (likely enhanced by moisture pooling near the boundary). Any remnant convective boundaries may result in additional thunderstorm development on Friday. Another MCS may affect at least northern Oklahoma late Friday and Saturday. If this MCS tracks across the same area that received heavy rainfall the previous night, flooding will be a concern. Isolated to scattered thunderstorms will remain possible into Saturday, especially east of I-35, where lowered mid-level heights will be located. Both the GFS/ECMWF continue to develop a 598+ dam mid-level ridge beyond Saturday. Therefore, expect hot and dry weather Sunday onward. Mahale && .PRELIMINARY POINT TEMPS/POPS...
