Rain and thunderstorms spreading to the East on Tuesday will put the brakes on the warmup following Easter weekend.
Most of the East, with the Northeast's I-95 corridor being the exception, will end Easter weekend on a milder note.
An even milder day will unfold throughout the East on Monday with highs in the 70s dominating the South and mid-Atlantic and 60s prevailing across upstate New York and New England.
Some communities in upstate New York and New England will crack the 70-degree mark, while others in the Deep South hit 80 F. However, air flowing in from the cold ocean will keep many mid-Atlantic and Northeast beaches cooler.
Further warming will occur on Tuesday east of the Appalachians, but advancing showers and thunderstorms will signal an end to that trend.
After spreading into the Midwest--rattling Chicago, St. Louis and Indianapolis in the process--on Monday, showers and thunderstorms will continue to track to the East and central Gulf coasts Tuesday through Tuesday night.
Odds favor the storminess waiting until later Tuesday reach the I-95 corridor. Boston and Portland should even remain dry through the daylight hours.
It is not out of the question that one or two thunderstorms become strong enough to unleash damaging winds and/or hail from Baltimore and Washington, D.C., southward.
The majority of Tuesday's showers and thunderstorms will instead prove to be disruptive to travelers and those with outdoor plans.
Even though severe weather will be limited, lightning remains a danger from any thunderstorm. If you hear thunder, remember that you are close enough to be struck by lightning.
The wet weather later Tuesday could impact the Major League Baseball games between the Los Angeles Angels and Washington Nationals in Washington, D.C., and the St. Louis Cardinals and New York Mets in New York City.
Showers will either reach Boston during the late innings or after the game between the city's Red Sox and New York Yankees at Fenway Park.
Other outdoor activities and sporting events may be forced inside, delayed or canceled.
While widespread heavy rain is not expected, enough rain could fall to trigger localized flash flooding issues across northern New England where rivers are running high and the ground is saturated from recent rain and melting snow.
Some snow may return to the mountains of northern New England Tuesday night if advancing cold air catches up to the rain. There may even be enough cold air in place for wet snowflakes to fly Wednesday morning in the higher terrain of New York State and northwestern Pennsylvania.
The cooldown in the wake of Tuesday's showers and thunderstorms will be far less dramatic than what was experienced earlier this week, preventing more places from seeing yet another round of wet snow or snow pellets.
Across the East, the cooler air will be noticed the most by residents and visitors to the Northeast on Wednesday. In addition to temperatures tumbling, brisk winds will blow and create lower AccuWeather.com RealFeel® temperatures.
