Scattered showers have developed this afternoon in a very moist and unstable airmass along and ahead of a stagnant frontal boundary draped across Oklahoma and western North Texas. At 330 PM, the heaviest showers were located along a line from Chandler, southwestward to near Noble and Blanchard in central Oklahoma, down to near Lawton and Grandfield in southwest Oklahoma. Additional showers and even thunderstorms will likely develop in this uncapped environment over the next couple of hours. While widespread severe weather is not expected, a few of the stronger storms could produce small hail and gusty winds. Additional storms are expected to fire along and behind the front this evening and overnight. These storms will pose a greater risk of large hail and perhaps damaging winds. Locally heavy rainfall is also expected, especially across the northern half of Oklahoma where the greatest storm coverage is forecast to occur through the overnight hours.
