In our story in today's Inquirer, we took note of the snow drought and attempted to place it some perspective.

A touch of snow is possible at the Shore this evening, and after a soaking mid-week rain, the region will undergo a significant cool-down through the hoilday weekend.

But the prospect of any signicant snow in the near future is all but non-existent, and the longer-term outlooks call for temperatures to warm up a bit next week.

At the end of the first week of January, the region still awaits its first "cold snap," defined by National Weather Service climatologist Mark DeLisi as three consecutive days in which the official temperature fails to get above 35.

We came reasonably close this week, but the reading at Philadelphia International Airport nudged up to 36 by lunchtime yesterday after consecutive daytime highs of 33 and 30.

Temperatures are heading to the 50s today and tomorrow, followed by a modest cool-down. But right now the next run at the elusive cold snap isn't in sight.

Catching up from the holidays, we note of a couple of post-season hurricane items:

Global warming is real, but its impact on hurricanes would be difficult to identify and probably wouldn't be all that significant, according to an essay by Chris Landsea, science and operations officer at the National Hurricane Center.

That is a simplification of a thoughtful piece, so here is the entire essay, with embedded images.

So far this winter, the weather forecasts have been about as compelling as the Eagles' playoff preparations, not to reopen a fresh wound.

Just the other day we were saying that no one should be surprised if the next measurable snow in Philadelphia didn't arrive until Groundhog Day.

Then, late last night, parts of the region were ambushed by a light snow that left the official measuring site in National Park, N.J., buried under 0.2 inches.

Despite widspread cooling across the tropical Pacific, the worldwide temperature once again was well-above long-term averages in 2011.

According to satellite data released this afternoon by NASA's John Christy at the University of Alabama, the 2011 temperature was 0.27 degrees Fahrenheit over the 33-year average.

That made it the ninth-warmest year in the satellite period of record, but not as toasty  as 2011, 0.73 degrees above average, the second-warmest on record.

We mentioned yesterday that December was the fifth-warmest on record in Philadelphia, and that a warm start argues against a snowy winter.

It is a compelling argument, looking at the 124 years for which official snow totals are available for Philadelphia.

In the 25 years with the warmest Decembers, the average seasonal snow total is 14.7 inches, or about two-thirds of long-term averages.

After two elite snow winters, perhaps this was inevitable.

You may have noticed that no measureable snow has fallen since Halloween, and don't be surprised if it doesn't happen again before Groundhog Day.

We are about to experience the coldest overnight since last Feb. 9, but not even a respectable snow threat appears in the longer-range speculations.
