Enough rain will fall on Maine and neighboring Canada into Wednesday to caused localized flooding problems.
A storm system tapping into some tropical moisture from Debby will continue to bring drenching rain to the region into the middle of the week.
Flash and urban flooding is in store, along with the potential for small stream flooding.
Unlike folks in the Ohio Valley and much of the mid-Atlantic, much of New England has experienced above-normal rainfall over the past several months.
The greatest rainfall departures in New England are over much of Maine. Rainfall since April 1 in the Pine Tree State ranges from 125 to 175 percent of normal.
This means the ground was already rather wet in the region and primed for flooding problems prior to the slow-moving storm's arrival.
During the 24-hour period ending at 9:00 a.m. EDT Tuesday, parts of the state have received between 1 and 2 inches of rain. Some areas have the potential to receive double and perhaps triple that amount before the storm weakens and moves away later Wednesday.
The heaviest rain moving forward with the current storm will stretch from northern and central Maine into potions of New Brunswick and Nova Scotia.
According to Severe Weather Expert Henry Margusity, "While the bulk of the rainfall has to do with a southward scoop of air high in the atmosphere capturing a storm at the surface, the scoop has also tapped into a small amount of moisture from Debby, still hovering near Florida."
Debby seems to be sharing some of her assets with folks up in Maine and neighboring Canada in this water vapor image taken early Tuesday, June 26, 2012.
Fortunately, it appears the bulk of Debby's moisture will stay south of New England.
Flash and urban flooding may continue to be a problem moving forward into July. While a broad area of heat will build from the central Plains to the East Coast, New England may once again resist the swelter in the form of clusters of drenching, gusty thunderstorms.
Dry and sunny conditions will continue in San Francisco for the official start to winter and the Christmas holiday.
Sunshine will return in full force for the weekend, the official start to winter, and Christmas in Los Angeles.
Big changes are on the way for parts of the Western and Central states late this week and into this weekend.
Similar to the days prior to Thanksgiving, the worst weather will focus on the days prior to Christmas as millions of travelers take to the roads and skies in the U.S. and southern Canada.
Warm air is forecast to surge into much of the eastern half of the nation by the weekend and will be accompanied by heavy rain and flooding risk in some locations.
