Fall is shaping up to be markedly warmer than usual in much of the United States, according to an outlook released Thursday by The Weather Company and Atmospheric G2.

Most will be warm: Above-average temperatures are expected from the Great Basin to the Northeast, with parts of the Southwest, Rockies and Northern Plains being the most above average.

The few exceptions may be the immediate West Coast, as well as the Southeast, from the northern Gulf Coast to the Delmarva Peninsula. Temperatures there could be pretty typical as a whole, running slightly above or below average.

L​et's examine each of the next three months.

September heat: Compared to the previous outlook, September has trended hotter in the West and Northern Plains.

I​t's in those areas we expect the heat to be most pronounced during the month, from parts of the Desert Southwest to the Dakotas and northern Minnesota.

H​owever, much of the West, Plains, Midwest, New York state and New England are also expected to have a warmer-than-usual September.

Expansive September warmth has become more common over the years.

"​We can see a distinct warming trend that has effectively made September the fourth month of summer," wrote Todd Crawford, Vice President of Meteorology at Atmospheric G2 in the outlook.

September's warmth may be more muted, relative to average, in the Southeast. One factor behind this is September is the peak month of what's expected to be an active Atlantic hurricane season.

October even more impressive: If you thought the September map above was impressive, take a gander at the October outlook below.

A massive swath from the Southwest to the Plains, Midwest and Northeast is expected to be much warmer than average in October. Only much of Florida and parts of the West Coast and Pacific Northwest may be somewhat closer to par during the month.

Once again, the depiction of less warmer temperatures in Florida could be due to increased rainfall during a still-active month of hurricane season.

November a tad less warm: November may finally offer temperatures that are closer to usual, at least for some.

That may be the case in most areas east of the Mississippi River, as well as much of the West Coast, including California. We even have a small area of western Washington that could trend a bit cooler than usual during what is typically one of the wettest months of the year there.

But for the rest of the country, November still looks to be warmer than average. That may particularly be the case from the Desert Southwest to the Rockies and High Plains.
