Discussion              

A very unsettled weather pattern continues for the Mid-Atlantic region during the next couple of days that will include the chance for severe thunderstorms and torrential downpours.  Any storm later today and tonight can produce hail, damaging wind gusts and even an isolated tornado. Torrential rainfall can produce localized flash flooding conditions. Low pressure will push to the Great Lakes today and a cold front will edge its way into the eastern states and this frontal system will not clear the area until mid-week. Later today, the upper-level support of low pressure over the Great Lakes will tend to become “negatively-tilted” and that will enhance upward motion in the region resulting in an increasingly unstable atmosphere and the potential of those severe thunderstorms. Weak high pressure should improve overall conditions by Thursday, but unsettled weather returns going into the weekend.
