Discussion

The month of June has been very wet throughout the Mid-Atlantic region and it appears that the final days of the month, and the beginning of July, will very likely bring more substantial rainfall to the entire area. Philadelphia is officially closing in on 9 inches of rain for the month and the wettest June of all-time is not out of the question given this type of pattern. By tomorrow, we’ll start to get under the influence of an approaching unusually strong upper level low pressure trough and its associated surface cold front. The central and eastern US have had multiple unusually strong upper level troughs to deal with during the past several weeks contributing to many severe weather and heavy rainfall events. By Friday, the surface cold front will reach the east coast and strong upper level low will become established in the upper atmosphere over the Great Lakes and Northeast US. As a result of this unfolding late week weather pattern, showers and thunderstorms will become even more numerous on Thursday and Friday with heavy rainfall and severe weather almost certain to be included in the mix. That strong upper level low will then tend to spin around for a few days over the Great Lakes and Northeast US as the surface cold frontal system grinds to a halt near the coastline; consequently, the threat for showers and thunderstorms will continue on Saturday, but that won’t be the end of the wet period. In fact, surface low pressure may form along the front later in the weekend maintaining the threat for showers and thunderstorms on Sunday and Monday with additional heavy rainfall and severe weather possible. The bottom line, the next week to ten days looks quite wet in the Mid-Atlantic region and flooding may very well become a major concern given the already saturated grounds.
