Besides heavy rainfall, there is a threat for severe storms on Friday. Gulf moisture will interact with slow moving or stalling front, causing strong to severe storms to develop late in the day. Forcing will increase at night, as the low level jet kicks in. Large hail and perhaps gusty winds may accompany the storm clusters that evolve across Ozarks. The tornado threat will be greatest across SW Oklahoma and W. Texas during the afternoon hours, due to veering winds in that location. Southwesterly winds are expected locally which is not condusive for rotating thunderstorms.
