Area Forecast Discussion National Weather Service Norman OK 247 PM CDT Sat Jul 4 2020 ...New LONG TERM... .SHORT TERM... (This evening through Sunday) Issued at 1214 PM CDT Sat Jul 4 2020 Thunderstorms chances will exist this afternoon in southwestern Oklahoma near a surface boundary moving slowly south/southwest. This boundary will intersect areas of very high temperatures and surface moisture by mid-afternoon. This evening thunderstorms are expected to move southeast from southeastern CO across the panhandles and may enter northwestern Oklahoma before dissipating Sunday morning. A short-wave trough entering southern California this afternoon may travel through the weak prevailing flow toward the panhandles and northwestern OK by Sunday afternoon. This may bring more thunderstorm coverage to west central and northwestern Oklahoma Sunday afternoon. && .LONG TERM... (Sunday night through next Friday) Issued at 244 PM CDT Sat Jul 4 2020 A shortwave trough is expected to move southeast across the Oklahoma and Texas Panhandles Sunday into early Monday. This combined with weak easterly flow should promote generous thunderstorm develop to our west. Some of the storms may move across mainly western Oklahoma and western north Texas during the evening and overnight hours. With the synoptic boundary south of the area on Monday, most of area should remain dry into Tuesday. However, with rather warm and humid conditions, isolated showers and thunderstorms will remain possible, especially across southern Oklahoma and western north Texas. A southerly wind will increase Wednesday in response to a system moving across the northern Rockies and Plains. A model or two also has a weak system moving across the central Plains by late Wednesday into Thursday. At this time, it appears any convection associated with this feature will remain north of Oklahoma. Models differ on how fast to build another mid and upper level ridge over the southern and central Plains with the GFS faster. This will bring a return of very hot weather by the end of the week. Heat Advisories may be required. The EC is slower which may allow a better chance of rain, mainly across the eastern third/half of Oklahoma during the late week/weekend. && .AVIATION... (18Z TAFS) Issued at 1214 PM CDT Sat Jul 4 2020 Light winds less than 12kts are expected except for a bit higher gusts this afternoon in western OK. VFR conditions are expected, but there is a chance for thunderstorms in northwestern OK overnight and again Sunday afternoon. && .PRELIMINARY POINT TEMPS/POPS...
