After Smashing November Monthly Records, A Breather From the Fall Heat Wave is Arriving

November 4,2016
Only a few hot holdouts in the Deep South and Gulf Coast are left after a fall heat wave smashed not only hundreds of daily records, but also some November monthly records. Heat relief, an odd thing to say in early November, is now moving in.
Thursday, November monthly record highs were tied in Atlanta (84 degrees) and Mobile, Alabama (87 degrees).
Dozens of daily record highs were tied or broken Thursday in the mid-Atlantic and South, including:

  • Jackson, Tennessee (87 degrees)
  • Atlantic City, New Jersey (81 degrees)
  • Georgetown, Delaware (83 degrees)
  • Pensacola, Florida (85 degrees)

Fortunately, relief is gradually arriving, as a cold front continues to slide southward. Let's break down where more records may fall, and when the relief arrives.

  • Cooler air will arrive in much of the East, and the Southeast will be a tad cooler but still warmer-than-average.
  • Highs 10-20 degrees above average will warm the Plains, Midwest and South. 
  • 60s and 70s will surge as far north as the Canadian border with North Dakota.
  • Cooler 40s, 50s and 60s will be the rule in the Northeast.
  • 70s will replace the recent record heat in the Tennessee Valley, as 80s are pushed into the Deep South and Gulf Coast where a couple of daily record highs are still possible.
