Hazardous Weather Outlook National Weather Service Norman OK 410 AM CDT Sun Jun 24 2018 OKZ004>048-050>052-TXZ083>090-250915- 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- 410 AM CDT Sun Jun 24 2018 This hazardous weather outlook is for portions of northern... western...central...and southern Oklahoma...and western north Texas. .DAY ONE...Today and Tonight... .Thunderstorms... There is an enhanced risk for severe thunderstorms late this afternoon and tonight for much of northern, central and western Oklahoma. A slight risk surrounds the enhanced risk and includes much of the remainder of central and western Oklahoma. A marginal risk includes much of the remainder of the area, including much of western north Texas. Location... The enhanced risk is west and north of a line from Blackwell to Guthrie to Anadarko and Hobart. The slight risk covers areas outside of the enhanced risk and north of a Holdenville to Duncan and Hollis line. Timing... Main time for severe storms later today will be from 7 pm through 3 am. Impacts... Hail up to the size of golfballs. Damaging wind gusts between 60 to 80 mph. Heavy rainfall that may cause localized flooding. The tornado risk is low. Discussion... A complex of strong to severe storms will continue to push east and southeast across parts of Oklahoma this morning. Damaging wind gusts will be possible with this activity before it moves east of the area later this morning. By late this afternoon, additional thunderstorms are expected to develop to the west and northwest of Oklahoma. Initially the storms are expected to remain more isolated and instability and wind fields will be favorable for supercell thunderstorms that will have the potential to produce all types of severe hazards, including large hail, damaging wind gusts and possibly a tornado or two, especially as they move into far western and northwestern Oklahoma. These storms will then develop into a line of storms that will move east and southeast across much of Oklahoma overnight tonight. Damaging wind gusts and heavy rainfall will be the main impacts with these storms. .SPOTTER AND EMERGENCY MANAGEMENT STATEMENT... Storm spotter groups and emergency management personnel across the risk area should prepare for severe weather operations late today and tonight. .DAYS TWO THROUGH SEVEN...Monday through Saturday... .Thunderstorms... There will be a chance for thunderstorms Monday into early Tuesday. A few strong thunderstorms are possible Monday. .Heat... Heat index values from 100 to 105 degrees are forecast through much of this week. If you will be outdoors, limit strenuous activities and take frequent breaks.
