Ultra-Hot Weather to Leave Northeast, May Not Return

By Alex Sosnowski, Expert Senior Meteorologist
Accuweahter.com reports, a pattern change coming late this week may not only chase away ultra-hot weather in the short term, but it may keep long spells of 100-degree temperatures away for weeks to come.
A strong cool front, plowing through the Great Lakes Wednesday, will make steady progress through the Northeast Thursday into Friday.
The front will erase the hot, humid conditions again building over the region at midweek. Highs in the 90s will soon be a thing of the past, being replace by highs in the 70s in the mountains and over much of New England to the low to mid-80s over much of the Interstate 95 mid-Atlantic corridor.
A southward dip in the jet stream, which appears will have some staying power in the weeks ahead, could not only bring very comfortable conditions through the weekend but may also take the edge off the extreme nature of the heat in the long term.
While the pattern during the first couple of weeks of August will still produce its share of 90-degree days, they may be more infrequent and less likely to come in packs of three days or more.
New York City has averaged around 5.5 degrees above normal for July. Through July 27, the Big Apple has averaged 81.8 degrees. If this temperature holds, it would be the warmest month on record. Thus far, July 1999 holds that mark with a 81.4-degree average temperature. Records in New York City date back to the mid-1800s.
It is a similar story for many other cities in the I-95 corridor. Washington, D.C., has averaged 83.3 degrees so far this July. The hottest month on record for the city was 83.0 degrees during July of 1999.
While temperatures may continue to average above normal for much of the Northeast during the first half of August, the departures are likely to be less severe, compared to that of July.
The pattern change upcoming may still favor bouts of high humidity and rounds of showers and thunderstorms, but that is a subject for another story.
