730 PM Nowcast for Oklahoma/Storm Update

Around 700 PM…strong to severe thunderstorms were across portions of south eastern and south central Oklahoma. These thunderstorms were developing ahead of dryline which extended from near Luther to Washington to near Velma. The dryline had become near stationary with a slight regression back towards the west. The cold front had begun to overtake the dryline across portions of Lincoln and Oklahoma counties in central Oklahoma. The cold front was analyzed along and near a line from Stillwater to Oklahoma City to Bridge Creek and back westward towards Bessie and Erick. Strong winds were also noted across portions of extreme southwestern Oklahoma near Hollis..Altus…and Grandfield with wind gusts approaching 35 to 40 mph. Thunderstorms will continue to move towards the east northeast into the evening hours ahead of the dryline. With strong shear and sufficient instability in place…most storms will become severe quickly and will have the potential to produce very large hail…strong damaging winds and tornadoes. The cold front will overtake the dryline from north to south as the evening progresses. A few additional thunderstorms cannot be ruled out as this process occurs. Strong westerly and northwesterly winds will elevate the wildfire potential into the early evening hours. A few areas of blowing dust will also be possible across southwestern Oklahoma.
