Area forecast discussion, Jun 14, 10:45 PM CDT, 1 hour 56 minutes before
Area Forecast Discussion...UPDATED National Weather Service Norman OK 1045 PM CDT Fri Jun 14 2019 .AVIATION... 15/06Z TAFs. VFR conditions expected through most of the forecast period, although IFR/MVFR conditions appear possible across northern Oklahoma terminals first 3 to 6 hours of forecast with TSRA skirting OK/KS border. Some MVFR cigs possible farther south into central portions of Oklahoma toward 10-12Z then mix to VFR before noon. LLWS will be included through 12Z with strong low level jet over the region. Numerous TSRA possible toward end of forecast period and especially beyond tomorrow night into Sunday. && .PREV DISCUSSION... /issued 1004 PM CDT Fri Jun 14 2019/ UPDATE... No significant changes were made to the forecast. DISCUSSION... There remains some uncertainty on the southern extent of the MCS currently across Kansas. Zonal flow aloft will tend to keep most of the convection to the north. Nevertheless, with a strengthening low-level jet (~50 knots), some southern growth into Oklahoma is possible. Damaging wind gusts will be the primary hazard. In addition, a lone thunderstorm across the Texas panhandle may affect far western north Texas before dissipating. Mahale PREV DISCUSSION... /issued 638 PM CDT Fri Jun 14 2019/ AVIATION... 15/00Z TAFs. VFR conditions expected to prevail through most of the forecast period. TSRA expected to mainly affect northern Oklahoma terminals, generally in the 02Z-08Z time frame with main impact being damaging wind gusts. Could see more isolated TSRA farther south toward KCSM and KOKC. Farther south, elevated warm layer has greater chance of suppressing any TSRA this forecast period. Frontal boundary expected to switch winds to northwest at KWWR with s/sw winds prevailing elsewhere. PREV DISCUSSION... /issued 341 PM CDT Fri Jun 14 2019/ DISCUSSION... Convection now developing in eastern Colorado is the beginning of what should become scattered thunderstorms across the southern High Plains region by this evening. Strong instability suggests that any storms that form could be quite severe, with very large hail and very strong winds. It is expected that these storms will coalesce into one or more storm clusters, and move east tonight. In this phase, strong winds will be the main threat. In our forecast area, it is most probable that a storm cluster will follow the Oklahoma/Kansas border area tonight. Storms should diminish in the morning Saturday, leaving a partly cloudy day with relatively warm temperatures. Storms are expected to form again tomorrow evening, and severe storms will be possible again, similar to today, but farther east than today. As an upper-level wave passes over Oklahoma on Sunday and Sunday night, even more widespread strong/severe thunderstorms are expected. In the wake of the departing upper wave, Monday should be relatively dry (meaning lower rain chances, not lower humidity). The upper-level pattern doesn't change much next week, and difficult-to-time minor waves in the upper flow will cause occasional similarly-difficult-to-time chances of storms. && .PRELIMINARY POINT TEMPS/POPS...

Hazardous Weather Outlook...UPDATED National Weather Service Norman OK 830 PM CDT Fri Jun 14 2019 OKZ004>048-050>052-TXZ083>090-160130- Harper-Woods-Alfalfa-Grant-Kay-Ellis-Woodward-Major-Garfield- Noble-Roger Mills-Dewey-Custer-Blaine-Kingfisher-Logan-Payne- Beckham-Washita-Caddo-Canadian-Oklahoma-Lincoln-Grady-McClain- Cleveland-Pottawatomie-Seminole-Hughes-Harmon-Greer-Kiowa-Jackson- Tillman-Comanche-Stephens-Garvin-Murray-Pontotoc-Coal-Cotton- Jefferson-Carter-Johnston-Atoka-Love-Marshall-Bryan-Hardeman- Foard-Wilbarger-Wichita-Knox-Baylor-Archer-Clay- 830 PM CDT Fri Jun 14 2019 This hazardous weather outlook is for portions of northern... western...central...and southern Oklahoma...and western north Texas. .DAY ONE...Through Tonight... .Thunderstorms... There is an Enhanced Risk of severe storms over far northwest Oklahoma, and a Slight Risk for the rest of northern Oklahoma. A Marginal Risk extends to the south of the Slight Risk area. A complex of thunderstorms is expected to enter northwest Oklahoma late this evening. Thunderstorms may continue to move across northern Oklahoma through the overnight hours into Saturday morning. Wind gusts up to 70 mph and hail up to the size of golf balls will be primary hazards with any severe storms. Locally heavy rain that could reduce visibility and produce minor flooding will also be possible. .DAYS TWO THROUGH SEVEN...Saturday through Thursday... .Thunderstorms... Severe storms will be possible again Saturday afternoon and night with a Slight Risk generally west through north of I-44. A Marginal Risk covers most of the rest of the area. Very large hail up to the size of baseballs and damaging winds will be the main threats. On Sunday, a Slight Risk covers most of the area. What happens Sunday could be affected by the storms that occur Saturday night so there is some uncertainty. Large hail and damaging winds will be the main concerns with severe storms Sunday. Thunderstorm chances will continue off and on next week, with strong to severe storms remaining possible. Locally heavy rain and flooding will also be a concern this weekend into next week.
