Forecast Discussion

A cold front will stall over the state this morning before slowly exiting this afternoon. The proximity of the front along with a warm, moist flow at the surface may allow for a few isolated rain showers or thunderstorms this morning. Convective activity will taper this afternoon and evening as the front departs and a weak dry slot works in ahead of a secondary cold front approaching from the west. As the secondary front approaches, clouds will once again thicken and lower before resettling as summit fog on Tuesday. As the front moves in Tuesday, showers and thunderstorms will spread in, with the greatest activity occurring after midday and then continuing overnight. Some thunderstorms on Tuesday could bring violent winds, small hail, or heavy periods of rain.
