“Afternoon high temperatures in most locations Wednesday and Thursday will be higher than what occurred during the middle of April,” AccuWeather Senior Meteorologist Mike Doll said.

From April 13-14, temperatures in the 70s and 80s were felt across a large portion of the mid-Atlantic, but cool air kept its grip on New England.

The entire Northeast will experience the warmup this go-round.

During the second half of the week, temperatures are likely to crack the 90-degree Fahrenheit mark for the first time this year in Baltimore, Washington, D.C., and Richmond, Virginia.

Philadelphia and New York City also have a good shot at hitting this mark.

Daily record highs will be in jeopardy along the I-95 corridor.

In Baltimore, Thursday’s record of 91 F dating back to 1913 could be matched or exceeded.

An uptick in humidity will accompany the summerlike temperatures, which will push AccuWeather RealFeel&reg Temperatures several degrees higher than the actual thermometer reading.

“It will definitely feel like summer,” Doll said.

The warmth will come to the delight of outdoor enthusiasts and MLB fans and players who endured many chilly games during the month of April.

However, not all locations will be rain-free during the warm spell.

Showers and locally strong thunderstorms from an approaching storm will scoot across the northern tier, mainly through New York state and New England, late in the week.

Will warmth last into the second week of May?

The same system that will trigger multiple days of severe weather over the central U.S. and help to pump the warm air into the East this week will slowly advance toward the Atlantic Coast into the weekend.

Cooler, drier air will sweep in behind the showers and thunderstorms this weekend but will be a far cry from April's unseasonable chill.

“What will be different compared to earlier in April is the warmth will not come to an abrupt end with temperatures going from 70s and 80s to 40s and 50s in one day,” Doll said.

“Instead, temperatures will lower to near average for early May next weekend as opposed to temperatures more typical of March,” he said.

Some cool nights are ahead next week, however.

"It is possible that the normally cold spots in the central Appalachians, upstate New York and New England may have some frosty mornings early next week," according to AccuWeather Senior Meteorologist Alex Sosnowski.

"Potentially a light frost could cause more trouble than last week's freeze in some locations as this week's warmth will push more buds to leaf and blossom while many people will be gathering annual flowers and vegetable plants from garden centers," Sosnowski said.

Based on how the weather has been this spring, it may be best to go by the average date of the last frost before planting tender crops and flowers in the garden, rather than how the weather was last year.
