Snow and Ice Forecast for Monday
Thunderstorms Monday for the Southern Plains
Daytime heating and increased moisture ahead of a dryline will allow instability to build across western Oklahoma and the Texas Panhandle. The dryline will push slowly into West Central and Central Oklahoma. This will provide lifting for the development of scattered thunderstorms along and ahead of the dryline. Hail and damaging winds will be the primary hazards with these storms, but an isolated tornado or two cannot be ruled out. Storms will become more linear later in the evening with damaging winds becoming the primary hazard. These storms will slowly move to the northeast with the threat diminishing overnight.
