Two storms will combine to bring clouds, areas of rain and thunderstorms to the mid-Atlantic into the end of the week.
A storm aloft dropping in from the Midwest and a surface storm near the North Carolina coast will combine forces.
Temperatures in the upper 60s and 70s and the sunshine that was experienced at midweek across the region will be replaced with clouds, showers and highs only in the 50s to low 60s by Friday.
"The weather has certainly been up and down in the Northeast this April, and that trend is expected to continue," said AccuWeather.com Meteorologist Evan Duffey.
As typical this time of the year, a roller-coaster weather pattern can bring large swings in the weather over the course of a few days.

Pittsburgh, Washington, D.C., Baltimore, Philadelphia, and Allentown, Pennsylvania, will experience a sharp turnaround in weather conditions as the end of the week approaches.
The coastal storm will cause a stiff wind to develop from northeastern North Carolina to southeastern Virginia and Delmarva by Friday. Seas will build offshore with locally rough surf possible on the beaches.
The heaviest and steadiest rain with this surface storm will remain off the coast, eliminating the threat of a washout either day. However, clouds, showers, and pockets of drizzle will occur across the region into Friday.
Farther inland across the eastern part of the Ohio Valley, Appalachians and mid-Atlantic, the storm aloft will bring the risk for heavier showers and thunderstorms into Thursday night.
These storms are not expected to be severe but could bring drenching downpours and even small hail in some cases.

According to AccuWeather.com Meteorologist Elliot Abrams, "little or no rain should reach Philadelphia or New York City, but an increase in cloudiness [and] a decrease in temperature appear likely."
The majority of the showers will stay south and west of New England during the dual storm event.
Any outdoor activities such as baseball games or outdoor picnics from southern and western Pennsylvania and southern New Jersey to Virginia and northeastern North Carolina could be disrupted.
Folks will want have sweatshirts and jackets handy along with an umbrella for Friday. A thick cloud cover will help to bring the coolest day across the region this week. There will also be a risk for a few showers across the region.
High temperatures will likely remain in the 50s across New England with 60s near the Appalachians.
"Temperatures on Friday will be around 10 degrees below normal," said Duffey.
While Friday will be the worst of the two days along part of the mid-Atlantic coast, the weather will begin to improve farther west. In fact some sunshine is in the offing for the Ohio Valley to part of the lower Great Lakes region.
If possible, outdoor activities in the mid-Atlantic should be put on hold until the weekend. The coastal disturbance is expected to pull away from the coast on Saturday.
"The clouds will give way to sunshine and it will start to turn warmer," added Abrams.
Chilly mornings over the weekend will give way to comfortable afternoons. Those heading outside later in the day Saturday or Sunday across New England will feel temperatures in the mid to upper 60s while people farther south in the mid-Atlantic will have temperatures in the 70s.

A warming trend is in store for next week.
