Severe Thunderstorms to Add to Flooding Woes
Strong thunderstorms will continue to pose dangers over the Ohio Valley, southern and central Appalachians and the southern Atlantic Seaboard tonight and may fuel more flooding in the Northeast this weekend.
While the storms may not bring all of the bells and whistles of the past few days from the Plains and lower Mississippi Valley, they will bring areas of blinding downpours, flash flooding and gusty winds through tonight from parts of Indiana and Ohio southeastward the Carolinas and Florida.
Several disturbances are driving the thunderstorms in these areas. The disturbances continue to rotate around a giant low pressure area, still anchored over the middle of the nation.

The worst of the thunderstorms have now cleared South Florida.
A few of the thunderstorms can trigger incidents of hail into the early evening hours, but the greatest threats from the storms overnight will be that of flooding or fueling the storm in the mid-Atlantic and southern New England this weekend.
There is concern of locally strong thunderstorms with gusty winds and hail for eastern North Carolina and eastern Virginia and lower Delmarva during the day Saturday.
Meanwhile, the moisture and energy from the storms in the Ohio Valley this evening will roll into West Virginia, western Maryland and southwestern Pennsylvania late tonight and Saturday, potentially leading to severe flooding in the Alleghenies.
The same concern is raised for any storms that get going in the southern mid-Atlantic Saturday. This moisture could be funneled over the heavy snow pack in the Catskills, adding substantially to existing flooding concerns.
AccuWeather.com will continue to keep you updated on the thunderstorm and flooding problems this weekend.

The "Dead of Winter," the one-month period when normal temperatures reach their lowest levels, has come to an end for much of the United States. Some people may find it odd that the "Dead of Winter" does not encompass the darkest day of the year (the first day of winter). That is due to a seasonal lag in temperatures. More heat continues to be lost than is gained from the start of winter until this time of year.
