Sweltering heat, humidity to be kept at bay across northeastern US through midweek

The heat and humidity that stifled the northeastern United States over the weekend will remain absent from the region through the first days of summer.

"Summer will start off with much lower humidity than the weekend, so even though it will still be warm, it will not feel nearly as steamy outside,” AccuWeather Meteorologist Brian Thompson said.

The first day of astronomical summer, which marks the longest day of the year north of the equator, begins on Wednesday.

Temperatures will hover near seasonable levels after surging well into the 80s and lower 90s over Father’s Day weekend and into Monday.

Average temperatures for late June range from the upper 80s F in the southern part of the mid-Atlantic to the lower 80s in the central Appalachians and middle to upper 70s in New England.

Less humid Northeast 6.20 AM

"In addition to the less humid days, the nighttime hours will be cooler and more comfortable for sleeping,” Thompson said.

Conditions will also be comfortable for those completing construction projects or yard work, going for a run or taking part in other summer activities, even during the hottest part of the day.

Sunscreen should be liberally applied as the sun’s rays are the strongest during the days surrounding the start of summer.

The lack of significant moisture will limit soaking showers and thunderstorms over the region when compared to recent days.

At most, a spotty shower or thunderstorm will roll through a few locations for a brief time through Wednesday.

Conditions will likely fluctuate between dry, seasonable and comfortable spells and stormy, hot and humid periods into the beginning of July.

Another surge of muggy air will nose into the region late in the week.

The next uptick in heat and humidity will fall well short of the levels achieved this past weekend.

“There will be another surge of humidity coming in on Friday, but it doesn't look like it will last as long as the most recent humid stretch,” Thompson said.

Should moisture from a brewing tropical system get drawn northward at late week, the risk of downpours will increase in conjunction with the rain and storms associated with an approaching system.

A more significant push of cooler, drier air could sweep across the region during the early part of next week.
