Bill's Tropical Moisture to Trigger Storms, Flooding in Mid-Atlantic, New England

Tropical Depression Bill is continuing to move through the eastern third of the country and leaving a drenched countryside in its wake.

The storm has a history of producing Flooding Rain Across North Texas, South-Central Oklahoma.

According to AccuWeather Meteorologist Steve Travis, "Bill will track along the Mason-Dixon Line through the weekend and produce heavy rainfall across Washington, D.C., Baltimore and Philadelphia."

"The heaviest rainfall will mainly be confined to areas right along Bill's track. Generally, 1-3 inches can be expected, causing concern for flash flooding along the path of the storm," Travis added.

The reason for the exacerbated rainfall is the slow-moving nature of the storm. "Any place along the path of Bill to the Atlantic Coast will be at risk for street flooding, rapid rises along small streams, travel delays and disruptions to outdoor activities." These impacts detailed by AccuWeather Chief Meteorologist Elliot Abrams earlier this week are still indicative of what residents can expect throughout this wet weekend.

As Bill tracks eastward, portions of the mid-Atlantic are expected to heat up into the upper 80s and middle 90s by this afternoon. Tropical moisture will combine with hot air and enough instability to result in some strong-to-severe storms.

Thunderstorms look to erupt in the midafternoon hours over the Appalachians and then track eastward across the Carolinas and Delmarva. These storms will be capable of producing damaging wind gusts, some hail and flash flooding.

After drenching the Ohio Valley into the mid-Atlantic on Saturday night into Sunday, remnants of Bill will shift slightly north and bring a wet end to the weekend for New England.

Showers and embedded weak thunderstorms look to be widespread across the entirety of the region tomorrow, so an umbrella, rain boots and a rain coat will be good items to have on hand when you leave the house.

Residents who have outdoor plans for Father's Day will want to stay in touch with AccuWeather.com MinuteCast® to monitor the start and end times of the rain.

Urban flooding and travel disruptions are a definite possibility on Sunday for New York City, Hartford, Boston and Portland. Torrential downpours will cause poor visibility for motorists and low ceilings for air travel. In urban areas, this is the type of rainfall that can collect in underpasses, on lawns and in poor drainage areas along highways.

If you have travel plans, be sure to stay in touch with the forecast along your route and check in with your airline for any delays or cancellations.
