A strong disturbance will begin to impact the area Wednesday into Wednesday night. By Wednesday morning, moisture advection into the mid-levels will be conducive for light rain showers could start to form west. The main surge of deeper moisture will overspread the area Wednesday afternoon allowing for scattered showers and thunderstorms to form in the afternoon and evening hours.

A few of these thunderstorms could turn strong to possibly severe.

Damaging winds and the threat of an isolated tornado would be the main concern from any thunderstorms that do turn severe Wednesday afternoon and evening.The front should be offshore by late Wednesday night, and the threat of severe thunderstorm activity will shift into the coastal waters. Post-frontal overrunning rain showers will persist through the overnight hours. Fortunately, temperatures will remain well above freezing in the lower 40s when this overrunning rainfall occurs. Strong winds will develop after the front moves through especially along the coast. Winds could gust as high as 40 mph at times. Christmas day and Saturday will bring sunny skies and cold temperatures.
