Labor Day could be a washout across parts of the East, but that may only be the beginning.
AccuWeather.com meteorologists are becoming increasingly concerned that rain from what is now Tropical Storm Lee near the central Gulf Coast will slowly head north along and in the wake of a slow-moving frontal boundary next week.
This could mean a rainy week mid- to late-week period for some from the Southeast north to the mid-Atlantic. In the worst-case scenario, renewed flooding could occur in areas hit hard by Irene.
Many locations that could be impacted by inches of tropical rain want nothing more to do with the wet stuff from Mother Nature (at least for now). Allentown, Philadelphia, Newark and New York City are all coming off their wettest months on record.
Beginning with the upcoming holiday weekend, very warm and humid air will trigger a few gusty thunderstorms ahead of the front over the Northeast, as indicated by Expert Senior Meteorologist Alex Sosnowski.
By Monday, as tropical moisture is introduced into the front, a steadier rain with a few thunderstorms is expected from the Tennessee Valley and interior parts of the Southeast all the way north to New England. This includes cities such as Atlanta, Charlotte, Washington, Philadelphia and New York.
It will also surely impact outdoor plans, such as barbecues and ball games, for those off work to enjoy the "last holiday of summer."
Beyond that, it remains a bit difficult to pinpoint where the heaviest rain from Tropical Storm Lee will end up next week. "All that tropical moisture has to go somewhere," points out Expert Senior Meteorologist Carl Babinski.
Since upper-level winds in the atmosphere will be weak and Lee could be cut off from the jet stream, the area of rain will be slow-moving and is expected to occur this weekend over the central Gulf coast.
Moisture ride seep northeastward along the front. If this happens it could mean days of rain for some across the East Coast next week. Even a few inches of rain could lead to more flooding given the wet ground and high river and stream levels.
Should the core of the moisture from Lee stay farther south, the big cities of the Northeast would be spared from the heaviest rain.
Also complicating the situation will be Katia, which still has a chance to impact the East by late next week. Right now, the most likely outcome for this potential hurricane will be a path between the East coast and Bermuda.
The consensus of the meteorologists at AccuWeather.com believe the path of Katia may be similar to Hurricane Earl from last year, the center of which never touched U.S. soil.
"At any rate, given how the tropics have gone so far this season, the situation in the East next week is bound to be complicated," added Sosnowski.
