“April showers bring May flowers” is the classic saying to help people get in the mood for a sunny spring. However, residents in the northeastern U.S. could be in for a rude awakening because of an out-of-season storm that could hit soon.

The Northeast will experience a wave of cold air coming down from Canada, mainly around Vermont, New Hampshire and northern Maine. Meteorologists believe that this sudden influx could be enough to cause a mix of rain and snow for the region by Tuesday, especially in more elevated areas of the states.

“It wouldn't be surprising to see flakes flying in places like Montpelier, Vermont, and Portland, Maine,” said CNN meteorologist Gene Norman.

Norman noted that if Portland does receive any measure of snow, it would be the latest the city has been hit since 1945.

Some other states have already been hit with some untimely winter weather.

Massachusetts was hit by sleet and snow throughout Sunday, making for an especially miserable Mother’s Day for parts of the state. This was due to the same cold front that rolled through the southeast U.S. that resulted in severe storms and flooding.

Residents of Washington, D.C., New York and Boston should also prep for a wet week as well due to a low-pressure front that could bring plenty of rain.

"Highs can be stuck in the 40s from central and northeastern Pennsylvania to New York state (away from New York City) and parts of southern New England," according to Kristina Pydynowski of AccuWeather.com.
