An extreme pattern evolved this weekend just as Nate came ashore on the Gulf Coast, the 4th US hurricane landfall of 2017. A 2nd unusually deep, cold trough has dove down the Rockies and brought the first snowfall of the fall to Denver but an equally anomalous downstream ridge means summer lives on.
In these extreme cases, you get a huge variation in weather across a small area. Denver sees snow while Dallas sees record 90s!
Nate’s enhanced heat and humidity pump is sure being felt.
ON THE COLD SIDE

ON THE WARM SIDE
The thermometer read 70 degrees up as far as the Canadian border at dawn yesterday as Caribbean level humidity swept the East Coast. The strong flow stemming from the deep tropics continues to present mid summer-like heat and humidity all the way to Canada.
Hurricane Nate helps warm East, Canada: At Messena, NY, avg low is 39 but they had 70! One station in PEI, Canada broke record HIGH at 9 AM! pic.twitter.com/6FGdzQtSTW

Today's low of 68F (if it holds 3 more hours) ties the 2nd warmest October low ever recorded in Boston. Balmy stuff.

At 10:00 pm on October 9th, NYC had a temperature of 76 and a dew point of 74 (!) — have to imagine the latter is near an October record.
