Area Forecast Discussion National Weather Service Norman OK 244 PM CDT Thu Jul 30 2020 ...New SHORT TERM... .SHORT TERM... (This evening through Friday) Issued at 227 PM CDT Thu Jul 30 2020 Showers/thunderstorms are likely to develop across southwestern OK and western north TX this afternoon and evening a mid-level trough and surface boundary. Latest radar imagery shows a few echoes with a few cloud flashes already developing over Beckham County in western OK and tracking quickly east-southeastward at about 40 mph. With a moderately unstable atmosphere in place, little to no CIN, storms may become severe later this afternoon and evening. Large hail up to the size of golf balls, damaging winds, and heavy rainfall are possible with any storms that develop. A few thunderstorms are also possible this evening over northern Oklahoma. Precipitation appears likely, generally south of I-40, through at least 10PM with chances diminishing after midnight. && .LONG TERM... (Friday night through next Wednesday) Issued at 220 PM CDT Thu Jul 30 2020 In the wake of Friday's storm system, we should see a break from rain this weekend with below normal temperatures. Models (both deterministic and ensemble) are trending further west with their possible MCS Sunday night into Monday, affecting mainly the panhandles and parts of western Oklahoma into north Texas. Latest NBM guidance seems to represent this fairly well. The most recent WPC cluster analysis is coming in weaker and slower with the building of the upper level ridge next week. This is consistent with deterministic models which keep us in an active northwest flow pattern through much of next week. Day && .AVIATION... (18Z TAFS) Issued at 1251 PM CDT Thu Jul 30 2020 As of 18Z, a prefrontal trough axis appears to be located from near Bristow to OKC to Elk City, with a cold front situated over NW Oklahoma. Winds have already shifted to the northwest for WWR/PNC and winds are forecast to shift northwesterly for all other TAF sites by evening. Showers/thunderstorms have already developed from Holdenville to Ada, though none have been severe so far. Thunderstorms are forecast to develop near KLAW and KSPS sites this afternoon after 21Z. There is some uncertainty as to the placement and duration of precipitation. However, model guidance suggests precipitation may linger over this area until the early morning hours on Friday. && .PRELIMINARY POINT TEMPS/POPS...
