In the history of Philadelphia snowfall, this date remains in a class by itself.

It was on Oct. 10, 1979, that 2.1 inches of snow was recorded officially at Philadelphia International Airport.

No other season has come close for a first snowfall.

Fay, Gonzalo, Hanna, Isaias … Those would be the next names in an Atlantic tropical-storm season still stuck on Edouard.

The Atlantic, Gulf of Mexico, and Caribbean have been dead quiet since Edouard had its 15 minutes as a major hurricane in the open Atlantic and then spun into obscurity last month.

Based on climatology, the sun is setting on the season. On average, only one hurricane, a storm with peak winds of at least 74 m.p.h., forms after Oct. 7, according to the National Hurricane Center.

The  final results are in, and the Arctic ice cover reached its sixth-lowest extent this year in the era of satellite recordkeeping, dating to 1979, according to the National Snow and Ice Data Center.

While 2014 nudged last year to No. 7 on the list, the overall seasonal loss between the high and low points – March 21 and Sept. 17 – was the least since 2006, the center said.

The total areal coverage, 1.94 million square miles, was significantly higher than the 2012 nadir – 1.32 million square miles – but the center said that overall ice is vanishing at the rate of 13.3 percent per decade.

As widely reported, some of the tree species around here and elsewhere in the Northeast got a brisk start on the season with early splashes of color.

In its weekly update, the Pennsylvania Bureau of Forestry noted that the oaks have been taking their good old times, compared with the early-changing maples, dogwood, and ash.

“This should result in a longer than normal autumn display,” that’s providing some nasty thunderstorms don’t come along with leaf-removing gusty winds.

In John Bolaris’s post this morning he suggests that the region might be in for a cold and stormy October.

That certainly could well happen, but four other outlooks we’ve seen come down on the warm side for the month, with one other on the fence.

Based on the questionable history of longer-range outlooks, we are prepared to say that we are unashamedly clueless about what’s going to happen. Those who speculate have our admiration.

In its report last week the U.S. Drought Monitor expanded its “abnormally dry” zone to include all of Bucks and Montgomery Counties, portions of Philly and Chester County, the Delco delta, and all along the Main Line.

That map will be updated Thursday, and we wouldn’t be surprised to see the yellow spread a little more, even with a shower or two tonight.

For the month, officially Philadelphia has had 1.69 inches of rain, or under 45 percent of the normal 3.65 inches, at the National Weather Service’s station at Philadelphia International Airport.

Despite the lifting of a hiring freeze several months ago, the National Weather Service still has over 500 vacancies -- a 14 percent shortage -- according to the weather service’s union.

As a result, union officials say, meteorologists – including the bosses in some forecasts offices --  are working on overdrive and overtime, and combat fatigue might be having an impact on forecast quality.

In the Eastern Region, which covers the densely populated areas from the Carolinas to Maine and from Ohio eastward, 81 positions  -- 15 to 18 percent -- are unfilled, said David Solano, the regional union official and a hydrologist at the weather’s service river-forecast center, in State College

The coastal storm now pulling away has been a not-so-gentle reminder that the seasons very definitely have changed. Now comes some more-pleasant reminders.

The U.S. Forest Service has begun posting its foliage updates, based on eyewitness reports, although what we’re seeing on the site right now doesn’t tell us a whole lot.

The Pennsylvania Bureau of Forestry map is well-detailed and for our money is one of the best foliage sites out there.
