Area forecast discussion, Jul 3, 6:14 PM CDT, 2 hours 44 minutes before
Area Forecast Discussion National Weather Service Norman OK 614 PM CDT Wed Jul 3 2019 .AVIATION... Scattered storms may continue a few more hours before dying down with the setting sun. There is some indication of lower clouds building over eastern Oklahoma overnight, but chances are low for it to impact any of our TAF sites. Scattered storms may be possible again tomorrow afternoon, though chances will be very low. Day && .PREV DISCUSSION... /issued 257 PM CDT Wed Jul 3 2019/ DISCUSSION... A weak mid and upper level shear axis will translate east through Thursday, with overall height rises in its wake by Friday. Therefore, after this evening/overnight, the coverage of storms will be lower than the past several days. Meanwhile, a small cluster of thunderstorms, just north of the OKC area, has been building slowly southward this afternoon. The cold pool with this activity will likely foster more development into central Oklahoma through the mid evening hours. Other isolated storms may develop during peak heating along and east of the aforementioned shear axis. The stronger storms will be capable of producing strong to near severe wind gusts along with high rainfall rates. Most of the storms should decrease/dissipate near sunset. Over the weekend, a shortwave trough may move along the northern periphery of a mid level ridge. This will result in a better chance of storms across at least northern Oklahoma. The trend going into next week is for hotter temperatures with little or no chance of rain. && .PRELIMINARY POINT TEMPS/POPS...
