Not only was March quite warm around here, evidently it was toasty all over the world.

Overall, it was the warmest March on record worldwide, according to the government's National Climate Data Center. The combined land and sea-surface temperature, 56.3 Fahrenheit, was 0.06 degrees above the previous record set in 2002.

The climate data center, whose records date to 1880, also reported that the January through March period was the fourth-warmest such period ever.

That Eyjafjallajokull volcano in Iceland may be creating havoc with air travel, but so far it doesn't appear to be posing any threat to weather and climate.

In 1991, the spectacular eruption of Mount Pinatubo in the Phillipines spewed so much ash into the upper atmosphere that the volcanic veil resulted in a worldwide cooling.

So far, said Rutgers University volcano expert Alan Robock, not much in the way of sulfur dioxide has been ejected into the atmosphere by the Icelandic volcano, which blew for a second time yesterday.

This should be the last summery day for awhile, with temperatures cresting in the low to mid-80s, followed by thundestorms, followed by April. But this has been yet another historic run of weather.

The official high yesterday, 89, missed the record in Philadelphia by a degree. And believe it or not Philadelphia was a regional cool spot.
 
In New York, the temperature hit 92 in Central Park, the earliest 90-plus reading ever, and it smashed the old standard of 89, set in 1929.
 
Newark hit 92, a record; Boston, 90, a record, but perhaps the most impressive show of April warmth has occurred atop Mount Washington in New Hampshire, a summit that prides itself on having the worst weather on Earth.
 
The Mount Washington Observatory reported a high of 50 yesterday. Yes, that was a record – and it represented a cool-down.
 
On April 3, the thermometer hit a new summit for the date, 56 smashing the old record by an astonishing 14 degrees. For the 24-hour period, the temperature was about 30 degrees above normal.
 
In Philadelphia, the 1929 heat spell was more impressive, with two 90-plus readings. However, as mentioned in The Inquirer today, this was the warmest first week of April ever.
 
The final average temperature for the seven days came in at 64.5, beating 1929’s 61.3.

Exactly two months ago, the region was between snowstorms that left unprecendented amounts of snow in such a short period -- almost four feet in six days.

This afternoon, the official Philadelphia temperature has hit 89, just a degree shy of the all-time record, set back in 1929. Today, Philadelphia is one of the warmest places in the nation.

While Feb. 7, 2010, and April 7, 2010, may bear no similarities, the winter and spring do share a weather bond of sorts, according to Bruce Terry, a meteorologist with the government's Hydrometeorological Prediction Center, outside Washington.

On an afternoon more typical of July in northern Arizona, the official temperature in Philadelphia is challenging a record for the second consecutive day.

At 3 p.m., the thermometer at the airport was reading 89.1 degrees, or 0.9 degrees shy of the all-time high set in 1929. Yesterday's high, 87, tied the record for the date.

And that air out there is bone dry. The relative humidity at 3 was a very un-Philadelphia-like 20 percent -- about what it was at Grand Canyon, Ariz.
