Soaking, dreary rain to spread up eastern US early this week

Rain threatening to cause flooding in the Carolinas into Monday will also put many outdoor plans in jeopardy in the Northeast through the first half of this week.

Rain coats and umbrellas will be deemed necessities on one or two days from the Carolinas to New England.

Outdoor plans may have to be postponed or altered, while travelers can face slower conditions on roads and flight delays. Even worse, areas of flooding may occur.

The greatest risk for flooding will spread from the southern Appalachians on Sunday to more of the Carolinas on Monday and Monday night.

Carolina flooding April 23

A total of 2-4 inches of rain is expected to fall from Charleston, South Carolina, and Wilmington, North Carolina, to Raleigh, Winston-Salem, Charlotte and the neighboring foothills.

Low-lying and poor drainage areas may flood, while streams may rise and inundate adjacent land and roads. Motorists should prepare for possible road closures.

Localized rain amounts of around 6 inches would lead to more significant flooding and greater hazards to lives and property.

In addition to the flood risk, the coastal plain of the Carolinas may face isolated strong thunderstorms with damaging winds on Monday.

There should be fewer incidents of flooding as the rain spreads across the mid-Atlantic and Northeast through the first half of this week. However, disruptions to outdoor plans and travel will be plentiful.

The steadiest rain will target the I-95 corridor, but dreary conditions should extend back to the eastern slopes of the Appalachian Mountains.

NE April 23

The rain will reach Washington, D.C., by Monday, New York City later on Monday and Boston by Tuesday. The rain will not taper off in the mid-Atlantic until Tuesday night and Wednesday. New England will have to wait until Thursday for dry weather to return.

MLB games set to be played in Baltimore, Philadelphia, New York City and Boston could face delays or postponements.

Due to the slow speed of the storm, persistent onshore winds will howl onto the mid-Atlantic and New England coast.

“Easterly winds can gust close to 40 mph along the New Jersey coast,” AccuWeather Senior Meteorologist Tom Kines said. Such winds will whip all of the mid-Atlantic coast on Tuesday before spreading to the New England coast at midweek.

Minor coastal flooding and beach erosion could ensue at high tides.

As the winds drive in air from the chilly ocean, below normal temperatures will accompany the rain.

Washington, D.C., and Philadelphia will join other communities in the mid-Atlantic that will have highs held to the 50s on Monday. Highs in the middle to upper 60s F are more common.

“Tuesday will be a blustery and soggy day for much of the Northeast’s I-95 corridor,” AccuWeather Senior Meteorologist Tom Kines said. “The combination of rain and a raw wind will make it feel more like early March than late April.”

AccuWeather RealFeel® temperatures may stay below 40 F all day in Boston on Tuesday, when a high near 60 F is more common.

A different story awaits for residents who live west of the Appalachian Mountains. Any rain from this storm will tend to be brief and near- to above normal temperatures will hold in Pittsburgh; Buffalo and Syracuse, New York; and Burlington, Vermont.

Above-normal temperatures will return to all of the Northeast later this week as the storm departs and warmer air surges in.
