Fall is just around the corner – it officially begins on Sunday, September 22, at 4:44 p.m., the Autumnal Equinox for 2013 – though many consider Labor Day to be the unofficial gateway to autumn. In many areas it already feels like fall, and in some, it has felt like fall for much of the summer.
You’ve already read our long-range outlook for the coming winter (right?), but what about the coming season? Will fall be furious or fabulous? Here’s what we think.
Cool, dry conditions should take hold during the opening days of fall, followed by a spell of biting cold and some unsettled weather in November and December.
Most regions should see some extremely pleasant days, punctuated by rain, through much of September and October. Halloween will be unseasonably cold this year for the Eastern states and provinces – so dress those little ghouls and goblins up in something warm. Farther west, we expect some light snow over the Rockies, and east into Texas, with rainy conditions in the Northwest, for Halloween.
As you may have seen in our hurricane season forecast, a very late-season tropical cyclone may adversely influence the weather around Florida and the Bahamas during mid-November. Around that time, the entire East Coast will see stormy conditions, and even some snow in the Mid Atlantic region.
Thanksgiving could coincide with a wintry storm moving across the Central and Eastern States, including up to six inches of snow for the Great Lakes region. Elsewhere, the holiday weekend will be blustery and cold.
As fall begins to blur into winter, we are red flagging December 16—19 as dates for major weather disturbances which could deliver widespread wintry precipitation.
