is Day 15 in the existence of Tropical Storm Nadine, which continues to scare fish in the far eastern Atlantic.
Nadine has been a model of persistence, but it's not even close to being a record-setter.
Dennis Feltgen at the National Hurricane Center informs that the endurance record is held by the so-called San Ciriaco hurricane, which survived from Aug. 4 to Sept. 3 in 1899.
We still have a few weeks to go around here before the trees begin to show their true autumn colors.
But in a development that may bode well for that's to come our way, to our north the leaves are showing signs of out-performing the 2011 varieties for color and intensity.
That's the report from Gale Ross at the Maine Deparatment of Conservation, where the trees are as much as 45 percent of the way toward peak color.
Temperatures are expected to fall into the 40s overnight in parts of the region, and Philadelphia should see its lowest readings since May 12.
The National Weather Service advises that under clear skies and generally light winds tonight, excellent for radiational cooling, patchy frost could whiten parts of the Pine Barrens and Poconos.
Because the area immediately near the ground tends to be colder than the air where the temperature is measured, it is possible to get frost even when the readings are above freezing.
At 10:49 a.m. tomorrow spring arrives -- in Buenos Aires and Sydney, Australia.
Up this way the equinox means the end of the astronomical summer and the beginning of fall, and it should begin promisingly enough.
The weather during most of the day should be splendid, with the sun breaking through mid-morning and temperatures heading into the low 80s.
Accu-Weather, the commercial service in State College, already has made as splash by calling for a snowier-than-normal winter along the Mid-Atlantic/Northeast coasts.
The government's Climate Prediction Center doesn't get into snow forecasts, but the winter outlook it posted this week offers some hope for those wouldn't mind a repeat or last winter, or a reasonable facsimile.
The climate center is saying the odds are tilted toward above-normal temperatures in about 60 percent of the country, from North Carolina to Idaho, in the Dec. 1-Feb. 28 period, and in Alaska.
In its 10th day as a fish storm, Nadine continues to spin rather purposelessly in the far-eastern North Atlantic, toward the Azore Islands that Columbus passed on his way to the New World 520 years ago.
Nadine was designated a named storm -- one with winds of at least 39 m.p.h. -- back on Sept. 12, and as of this afternoon, an "Oscar" isn't even a gleam in the atmosphere's eye.
Near the climatological peak of hurricane activity, that represents the longest lull between the development of fresh storms in the Atlantic Basin since Aug. 1.
Worldwide temperatures averaged 1.12 degrees Fahrenheit above 20th Century averages, good enough for No. 4 on the all-time warm list in records dating to 1880.
According to the National Climate Data Center August report, released this week, last month was ever-so slightly warmer than August 2011, but not quite as toasty as it was in 2010.
For the June through August period, the Northern Hemisphere's meteorological summer, global temperatures were the third-warmest.
Climate models still have a way to go before they can be counted on to attribute extreme weather events to global warming.
That's a point made in this Nature essay, published today. Worldwide warming isn't the only thing that could drive extreme weather.
That said, the article states that the emerging science of "climate attribution" is by no means a lost cause. It's just that the models have to get better at it.
