.DISCUSSION...

Moisture being pulled north into the area from Tropical Storm 
Imelda will lead to light to moderate rain chances in the area
through Tuesday evening before surface high pressure pushing
south out of Canada works its way into the Northeast. This
should work enough dry air into the region to lead to dry and
clearing conditions on Wednesday. This dry pattern looks to
continue through at least early next week. This rainfall combined
with recent rainfall earlier this week will lead to diminishing 
fire weather concerns over the next week or so.
