Winter might be coming to your screens tonight, but for the weather forecast, it’s anything but. The D.C. region will see two rounds of severe storms Sunday — one in the afternoon and one overnight — that could bring damaging winds, blinding rain, hail and possibly isolated tornadoes.



What to expect:

There is a severe weather threat late Sunday afternoon through early Monday morning, with the window for the biggest risk between 3 p.m. Sunday and 4 a.m. Monday.

The biggest threats are damaging winds and isolated tornadoes, the National Weather Service said.

“The severe storms will bring heavy blinding rain, strong damaging winds and there is a possibility for hail and even weak isolated tornadoes,” Storm Team4 meteorologist Clay Anderson said.

The first round of storms, expected to arrive between 5 and 8 p.m., will mainly impact areas northwest of Interstate 95.

The second round of storms, which will rake through the area overnight, will sweep through from west to east. The overnight storms are expected between midnight to 3 a.m. Monday.

Up to a half of an inch of rain is expected, posing a flood risk for areas vulnerable to heavy downpours.

“The main threat will be damaging winds … but an isolated tornado and isolated instances of flooding cannot be ruled out as well,” the National Weather Service said.

The National Weather Service’s Storm Prediction Center placed most of the Northeastern U.S. under what it categorizes as a “slight” risk for severe thunderstorms on Sunday.

Meteorologists urge everyone to keep up with the forecasts and have multiple ways to get warnings. When the storms strike, seek shelter.

“Remember: When thunder roars, get inside and away from windows,” Storm Team4 meteorologist Steve Prinzivalli said.


2 dead as severe storms ravage South

Powerful storms that killed at least two people continued to move across the South on Sunday after spawning suspected tornadoes that left several people injured and multiple homes and businesses damaged or without power.

In East Texas, the Angelina County Sheriff’s Office said an 8-year-old and a 3-year-old died when strong winds toppled a tree onto the back of their family’s car in Lufkin while it was in motion. Capt. Alton Lenderman said the parents, who were in the front seats, were not injured.

Mississippi State University’s 21,000 students huddled in basements and hallways as a tornado came near the school’s campus in Starkville. University spokesman Sid Salter said some debris, possibly carried by the tornado, was found on campus, but no injuries were reported and no buildings were damaged.

The large storm system also knocked out power to thousands and caused some flash flooding. The weather service said the system is expected to shift to the Ohio Valley and the Southeast on Sunday. More than 140,000 customers remained without power in Texas, Mississippi, Louisiana and Arkansas late Saturday.


Forecast:

Sunday’s storm system will have mostly cleared the area by dawn on Monday, bringing with it cooler air. Monday will be breezy with a slight chance of lingering showers in the morning.

Sunday: Cloudy, breezy, warm and humid with drizzle and scattered fog. Showers and thunderstorms likely after 3 p.m. Highs in the upper 70s.

Sunday night: Showers and thunderstorms. Some storms may produce strong winds and heavy downpours. Lows in the upper 50s to low 60s.

Monday: Scattered showers before 9 a.m., then gradually clearing. Partly sunny and breezy, with highs in the low 60s.

Tuesday: Sunny. Highs in the upper 60s to low 70s.
