SnowTober. Balmy Winter. Summery March. Earthday Snow. Nothing to See Here….
April 23, 2012
Cue Twilight Zone Theme. Then look for the Fox News announcement that the Global warming scare is over.
Video above discusses today’s record breaker, mentions unusual jet stream pattern. Sound familiar? It would if you had seen last week’s video.
Note also the Meteorologist from Arizona’s mention of record heat in his neck of the woods….
It’s been 84 years since there’s been a Nor’easter like this one.
On Monday morning, parts of Pennsylvania and New York were dealing with a springtime surprise — a late-season storm that put some areas under a foot of snow and cut power to thousands of residents. Even more snow was expected in the higher elevations of Pennsylvania and New York state, south of Buffalo, and northeastern Ohio.
The last time a big snowstorm hit so late in the season was 1928, according to Aaron Tyburski, a National Weather Service meteorologist in State College, Penn.
The current storm is not as widespread as the ’28 blast, which dumped 1 to 2 feet of snow on central Pennsylvania and south-central New York, the meteorologist told The Times on Monday morning. This one is “more localized and elevation-dependent,” he said.
The higher elevations of Pennsylvania had 6 inches of snow by Monday morning, with 12 inches reported in some areas, Tyburski said. The snow was expected to continue through Monday night, with those higher elevations receiving 6 to 8 more inches.
A number of America’s TV meteorologists and other broadcast weatherpersons have been accused by peer-reviewed climate scientists either of being greatly uninformed about the science of the basics of manmade global warming, or, at the very least, of shying away from any mention of it during broadcasts for fear of losing ratings by driving their audience away with worrisome news.
Instead, complain these scientists, U.S. TV weather journalists, feeling the need to provide some explanation for the unusual weather, often escape into a simplistic nearest-cause answer, blaming the extreme weather on “the jet stream,” while avoiding the science that connects the jet stream’s behavior to manmade global warming … as well as ignoring other larger global patterns that also project such extremes.
Weather and climate scientists have long known that jet stream patterns directly affect weather extremes.
Now, as the world’s global average temperatures continue to rise, the climate scientists also have new concrete examples of how that temperature affects the jet stream — which in turn brings more weather extremes.
When the Arctic is less cold in winter, they explain, there is less temperature difference with the warmer air to the south, which means the jet stream (which divides the two regions) is weaker, loopier, slower… and so, for one thing, weather systems don’t move as fast, get stuck over one region for days on end, unrelenting.

With that, Blakemore embedded my video from last week on the newest Jet stream research – see below if you missed it.
Two major Nor’easters this season: one in October, one in April
What’s crazy about this Nor’easter is that it is only the second significant Nor’easter of the 2011 – 2012 snow season. The other major Nor’easter occurred October 30 – 31. It’s pretty bizarre to have your only two significant Nor’easters of the season occur in October and April–and none in November, December, January, February, and March. I talked to a weather disaster expert in the insurance industry last week, who told me that NOAA’s National Climatic Data Center will probably end up classifying last year’s October 30 – 31 Nor’easter as 2011’s fifteenth billion-dollar weather disaster.
Record April heat in Phoenix and Las Vegas
As is often the case when a major Nor’easter is affecting the Eastern U.S., the jet stream is contorted to bring a strong ridge of high pressure over the Western U.S., accompanied by record-breaking heat. Phoenix, Arizona hit 105°F yesterday, its tying its record for hottest April temperature (previous 105° April temperatures occurred on 4/20/1989 and 4/29/1992.) Las Vegas, Nevada hit 99°F yesterday, the hottest temperature on record for so early in the year, and tied for the hottest April temperature on record. The mercury climbed to a scorching 113° in Death Valley yesterday, a record for the date, and the hottest temperature measured in the U.S. so far in 2012.
