The first full week of June is upon us in the Northeast, but Mother Nature has some tricks up her sleeve. A northerly flow through Wednesday will allow for the cooler-than-normal temperatures in southeastern Canada to end up into the Northeast, Not only will in being chilly, skies will be mainly cloudy and there will be rounds of showers that pass through.
Monday is going to feature record-breaking cool air in New England during the day. Most locations are bound to either tie or break their daily record low maximum, or record cold high temperatures. This is thanks in parts to widespread forecast highs in the 50s whereas it should typically be in the 70s. Portion of the Green and White Mountains will be even cooler with highs only in the 60s. Further south and west, temperatures will also be below average by up to 10 degrees as the cool air from the north moderates. This will translate to actual highs into the 60s and 70s across the Great Lakes, Ohio River Valley, and Mid-Atlantic.
On Tuesday, temperatures will remain well average, although it will be slightly milder than on Monday. High temperatures will be up to 10 degrees below average in the Mid-Atlantic and 15 degrees in New York and southern New England, but as much as 25 degrees below normal in northern New England. Another day of record low maximum temperatures are expected to be broken across northern New England and Upstate New York. Actual highs will range from the 50s in this region up to the 60s and 70s for remaining areas of the northeastern U.S.. In terms of low temperatures, they will not be record-breaking but they sure will be chilly for early-June with lows in the 40s and 50s. Parts of Maine and the mountains will even drop down to near-freezing — if not below freezing in a few areas.
Wednesday morning will be quite similar with widespread low temperatures in the 40s and 50s. Mount Washington, New Hampshire, one of the coolest spots this time of the year in the country, is forecast to drop down to about 27 degrees. Temperatures will rebound during the afternoon, rising into the 60s and 70s. Parts of New England and the higher elevations of New York will struggle to get out of the 50s.
For the remainder of the weekend, temperatures will return back toward normal with highs generally within 5 degrees of normal as the northerly flow becomes disrupted. That means that highs in the 70s and 80s will be commonplace across the Northeast region.
