Discussion

A weakening upper-level trough in the eastern US will give way to an intensifying ridge over the western Atlantic leading to a rather typical “Bermuda-high” summertime weather pattern. After a warm front pushes northward through the region later today, the stage will be set for warm and humid conditions and southwesterly flow on the backside of the Atlantic ridge will assure it’ll be a sustained period of “Bermuda-high” type weather in the eastern states. The chance for showers and thunderstorms will be relatively low on Tuesday, but will climb to higher levels from tomorrow into the upcoming weekend.
