The brief dose of April-like chill will gradually be replaced with rebounding temperatures this week in the northeastern United States with the late week featuring nearly perfect conditions for outdoor plans.
After ending the weekend with temperatures 10-20 degrees Fahrenheit below normal with interior snowflakes, the return of milder air is on the horizon.
The chill will begin to ease early in the week as the system responsible for the influx of arctic air departs into eastern Canada with even warmer weather to follow for late in the week.
"As an area of high pressure builds in from the west by the end of the week, the clouds and rain will be replaced by sunshine," AccuWeather Meteorologist Brian Thompson said.
The high will have to wait until after another storm system moves through Tuesday and Wednesday, putting the brakes on the early week warming trend.
Rain will spread from the mid-Atlantic to southern New England Tuesday into Tuesday night with fresh cool air to follow for most of the Northeast on Wednesday.
The stage should also be set for frost concerns in the coldest spots of the central Appalachians Wednesday night.
Once the high returns later in the week, residents will finally have an opportunity to enjoy outdoor activities that the recent chill and Tuesday's rain put a damper on.
Aside from a spotty shower in northern New England and near the border of the Virginias, dry weather will dominate late this week underneath a mostly to partly sunny sky.
"Since cool spells are so dependent on cloud cover and precipitation this time of year, just the return of sunshine will bring a sizable jump in temperature from Wednesday to Thursday," Thompson said.
That is especially true in terms of AccuWeather RealFeel® temperatures.
"The high will move offshore by Friday and Saturday, and the warm southwesterly flow on the back side of the high will give temperatures another boost," Thompson said.
Widespread highs in the 70s are expected across the Northeast on Friday, which will be a dramatic change from the highs that were held to the 40s near the eastern Great Lakes and around the 60-degree mark along the I-95 corridor on Sunday.
When compared to Sunday, RealFeel® temperatures will likely be 25-40 degrees higher on Friday due to more sunshine and a lack of gusty winds.
Jackets will not be needed for sporting events, yard or field work or any other outdoor plans. The weather in most communities on Friday night will be ideal for residents to start the weekend with a campfire, grilled dinner or at one of the baseball games in Philadelphia, New York City, Boston or Pittsburgh.
Whether the warmth persists through the weekend in the Northeast will depend on how far north a storm set to bring yet another round of downpours to the south-central U.S. tracks.
"Beyond this week, the trend in temperature will be upward," AccuWeather Long-Range Meteorologist Ed Vallee said, "though clouds and some rain may hinder any sustained warm-ups."
"As the last week of May approaches, the opportunity for a more sustained warm-up may be in the cards."
A cool shot may then send temperatures back toward normal by the first week of June, according to Vallee. Highs in the 70s are typical across the Northeast to start June.
Wednesday night of this week should also mark the last occurrence of frost this season in the central Appalachians.
"With the moderation upcoming, the threat for freezes will also come to an end for much of the country," Vallee said. "There may be a few instances where clear skies and light winds may allow for some frost along the Canadian border, but this threat will diminish toward the end of the month."
