After seemingly endless days stuck in a wet and cool weather pattern, springtime warmth is poised to return to the northeastern United States this week.Despite starting May with above-average temperatures, most locations so far are experiencing a month well below average.
For example, while the mercury hit 74 F in Albany, New York, on May 1, weeks of cool weather have dropped the average temperature for the month to 4 degrees Fahrenheit below normal. They even recorded a trace of snow as recently as May 9.
Areas across New England the higher elevations of the mid-Atlantic woke up to late-season frost just a couple of weeks ago, putting some agriculture in peril.
Some residents of the higher elevations of New England received several inches of snow just in time for Mother's Day.
Luckily, relief from the chill is in sight.
“Spring will return with a vengeance midway through the week,” said AccuWeather Meteorologist Brett Rossio.
“The morose weather pattern over the last couple of weeks will finally break down as a Bermuda High Pressure System sets up shop off the East Coast.”
The Bermuda High is a semi-persistent weather feature over the western Atlantic that is responsible for the calm, sunny climate of the Southeast and Caribbean.
As the most recent soaking nor’easter moves out of New England, the Bermuda High is expected to inch over the Eastern Seaboard.
“This will rotate a warm, southwesterly flow into the eastern third of the continental U.S.,” explained Rossio.

“Temperatures will soar 10-15 degrees above normal for this time of year - they will reach the low 90s for many.”
In Philadelphia, the favorable southwesterly wind will help temperatures increase from around 70 on Monday to near 90 on Wednesday and Thursday, despite average highs in the mid-70s.
The warmest weather of the week is poised to push through the region on Thursday, with highs in the low 80s reaching as far north as Bangor, Maine. New York and Boston could come within a few degrees of the record highs of 90 and 91, respectively, both set in 1936.
The mercury is expected to exceed 90 for the first time this year on Thursday in Hartford, Connecticut; Newark, New Jersey and Philadelphia.
There may be a slight cooldown at the end of the week as winds turn more from the north and west, but temperatures are likely to remain several degrees above normal into the weekend.
