We have an unusual upper air setup currently over eastern North America with a cutoff low anchored over the Appalachian Mountains with a circling ridge transporting intense Plains heat into northern New England. Quebec and the Maritimes.

So, while it’s mid to upper 90s in NORTHERN New England with a threat of monthly or even all-time record heat, it’s only in the 80s from DC to Boston. In fact BOTH Atlanta and New York City have yet to reach 90 this year.

One contributing factor to enhance the intense heat is the is the lack of rain. Dry ground leads to drier air and drier air makes for warmer temperatures.


The cool pool further south will trigger, showers, storms and somewhat cooler temperatures.


Not often is it Quebec or New Brunswick that sees the warmest air over the entire eastern side of North America but that was the case Thursday with Bathurst, New Brunswick reaching an astonishing 37.2C (99F).

Located on the typically fresher north shore of the St Lawrence River, Sept-Iles, Quebec recorded it’s hottest day in recorded history yesterday when the thermometer touched 36.6C (97.9F) while Îles-de-la-Madeleine and Mont-Joli set new June records according to Patrick Duplessis.

Quite the sharp thermal gradient.

Some northern Maine towns could push 100F today while it remains in 70s over the interior Mid-Atlantic.


Of course, when you’ve record heat, you’ve usually got snow somewhere else.
