Downpours, Storms Slide Into East
UPDATED 3:45 PM EDT, October 19, 2011
UPDATED By WeatherBug Meteorologist, Andrew Rosenthal
The East Coast, Ohio Valley and Great Lakes are having a soggy, stormy mid-week, with more to come through Thursday. A few dangerous thunderstorms across the Carolinas and Mid-Atlantic could trigger brief tornadoes and damaging winds later this afternoon and tonight.
There are two discreet storm systems driving these downpours and thunderstorms. The first storm system is a tropical disturbance that has been inundating the Southeast and Carolinas with heavy rainfall. One to 3 inches of rain has already added up in rain gauges across the Carolinas, and another inch or more of rain will be fall along the storm`s path through the Interstate 95 corridor. The heaviest rain will fall through tonight along the New England coast from New York City to eastern Maine, where as much as 3 inches of rain could accumulate.

Meanwhile, a second area of low pressure is cruising north from the Ohio Valley into the central Great Lakes, bringing another round of heavy rain to cities along the Great Lakes as it pulls moisture from the tropical low. Cities such as Chicago and Detroit could see rain gauges adding 2 or 3 inches by Thursday morning. A Flood Watch
has been hoisted for northern Ohio, including Toledo.
This combination of the tropical moisture and cold front being whipped eastward by the Ohio Valley low will bring plenty of moisture and energy into the Mid-Atlantic, increasing the risk of some strong to severe thunderstorms later this afternoon and evening. These storms will take aim from the Carolinas to the Washington, D.C., area, where gusty winds to 65 mph are possible, as well as a few tornadoes. The weather pattern later today is very similar to last Thursday, when tornadoes tore across northern Virginia.
