Summerlike Warmth to Ease in Northeast Next Week as Ana Brings Moisture

The combination of a cool front swinging in from the Midwest and moisture from a diminishing Ana will bring an end to the summerlike weather in the Northeast early next week.

Minor travel delays are possible in parts of the Northeast Monday and Tuesday, following several days of warm and tranquil weather.

Following a Mother's Day weekend in which many areas will experience high temperatures in the 80s under strong sunshine, increasing moisture will lead to an uptick in showers and thunderstorms from Sunday afternoon into Tuesday.

The July-like pattern will deliver AccuWeather RealFeel® Temperatures in the 90s in many cities during the afternoon hours.

At first on Sunday afternoon and evening, thunderstorms will be very spotty in nature. However, an increasing southerly flow of air ahead of the front will help to draw leftover moisture from Ana northward along the mid-Atlantic coast by Monday.

Ana became the 2015 Atlantic hurricane season's first named storm on Thursday night and is forecast to move onshore in the Carolinas later this weekend before weakening.

According to AccuWeather.com Hurricane Expert Dan Kottlowski, "Ana will gradually weaken later Sunday and Sunday night as it moves northward over eastern North Carolina and then southeastern Virginia."

Winds from Ana will generally not be an issue in terms of damage or power outages. However, there will be locally heavy downpours and isolated gusty thunderstorms. The downpours could slow the commute and bring sporadic airline delays.

"Eventually, what's left of Ana should pass near the Delmarva Peninsula on Monday," Kottlowski said.

The system could then pass near southeastern New England on Tuesday morning.

The weather from the mid-Atlantic to New England surrounding the showers and thunderstorms will be warm and humid on Monday into Tuesday, or very similar to July. Highs will be well into the 80s.

There will also be long breaks of rain-free weather in between the downpours.

According to AccuWeather.com Senior Meteorologist Dave Dombek, "While areas close to the track of Ana and just ahead of the front coming could have enhanced thunderstorms and rainfall, immediately west of Ana there may be a zone where it rains very little and stays relatively sunny."

Ana is not likely to bring beach erosion to the mid-Atlantic and New England coast, since the storm will have weakened significantly before passing nearby. Some moderate wave action will propagate northward from where the storm was stronger off the Carolinas.

Small craft venturing offshore should use caution as Ana could still generate locally gusty squalls and rough seas Monday into Tuesday.

After the remains of Ana move away and the front sweeps through, temperatures and humidity levels will be slashed.

High temperatures on Wednesday will be 10-20 degrees lower, when compared to the weekend with noticeably cooler nights from Pittsburgh and Buffalo, New York, to Washington, D.C., Philadelphia, New York City and Boston.

Temperatures in a few locations of the central Appalachians could flirt with frosty levels by Thursday morning.

Near- to slightly below-average temperatures are forecast for the latter part of next week in the Northeast, ahead of another rebound.
