I'd rather we had a gradual return to normal instead of a sudden switch to below normal weather. Oh well, I guess that's not happening. Why can't we ever have a normal spring and fall?
Cold coming next week looks expansive with huge negative anomalies for the Plains and interior west and into parts of the Midwest
I'm surprised that nobody has mentioned the new record high of 103 in Birmingham, Alabama, given that the violent evisceration of a monthly record by 9 degrees for a location with more than a century of data is probably unprecedented--though I'd love to see examples to the contrary.
Edit: I honestly wouldn't be shocked if this measurement were an error; it's just that extreme. Perhaps it will be revised down.

Reason: Additional Considerations
Large Canadian high pressure will build in from the west tonight.
This should allow for mainly clear skies, except for the far
southeast New England coast where some ocean effect clouds are
expected. It is a bit uncertain whether winds will completely
decouple, but there is probably a few hours toward daybreak where
that at least happens in the typical low-lying spots.
Given the dry and relatively cool airmass that will be in place,
expect overnight low temps to bottom out in the lower to middle 30s
in many locations. Based on these temperatures opted to go with
Frost Advisories for most of our region, except for Boston and the
far southeast New England coast. There remains uncertainty on the
extent of frost, which will depend on the how quickly winds
diminish. Nonetheless, do expect to see some frost especially in
those typical low-lying areas. A few of the normally coolest
locations may drop below freezing too, but did not have enough
confidence to issue any Freeze Warnings at this time, but later
shifts will have to monitor closely.

March 2012 had similiar anomalies in my region, with many locations beating monthly records by 10+ degrees.

Ah, the "summer in March". A case could still be made, given the considerably lower standard deviation of temperature associated with the time of year and region in which Birmingham's record was set, that the anomaly is significantly more extreme than those set in March 2012, though those are some numbers I'm neither equipped nor willing to crunch.
In any case, the boiling Autumn of 2019 in the Southeastern U.S. is certainly on the extreme end of weather phenomena, even if it won't be remembered like snowstorms and cold snaps.
