TWCCraig Posted April 17, 2013 Share Posted April 17, 2013 - Southern hemisphere is running .4 below normal - besides so much data has been falsified there is most likely a hidden agenda like with every other political issue - 1. Looking at NCDC data (which is only through February) the southern hemisphere is running 0.52 above normal 2. Regarding falsified data, it depends on where you get your data, satellite measurements indicate warming. Link to comment Share on other sites More sharing options...

Snow_Miser Posted April 17, 2013 Share Posted April 17, 2013 No one's sure but it is a fact that CO2 is a heat trapping gas. It's also a fact that solar activity, a past factor that has driven climate change on decadal and centennial time frames increased dramatically during the 20th century.

Allsnow Posted April 18, 2013 Share Posted April 18, 2013 Its a normal spring so far I feel it's kind of late landscaping wise. This will be our first week cutting and we will not be doing everyone. The trees I would say are still about 50% bare, with the rest starting to flower. Obv way behind last year, but last year was not normal. Link to comment Share on other sites More sharing options...
nzucker Posted April 18, 2013 Share Posted April 18, 2013 I feel it's kind of late landscaping wise. This will be our first week cutting and we will not be doing everyone. The trees I would say are still about 50% bare, with the rest starting to flower. Obv way behind last year, but last year was not normal. I agree that we're a little behind. Here in Dobbs Ferry, most of the maples don't even have the red pre-buds not to mention actual flowering; this means we're at least two weeks from leaf-out. Considering that the maples usually leaf out in the 4/20-4/30 time frame, and have been completely leafed out as early as 4/15 in warm years like 2010, things are delayed a bit. A few magnolia, Bradford pears, and apples are blooming but they're not out in large numbers yet. Two more days of relative warmth with 61F and sunny tomorrow should bring these flowering species into peak color, but warmer years have seen them peak in the first week of April. The landscape is just beginning to liven up at this point, a process that usually has been in motion for two weeks in the recent milder years. To add to the delayed spring, many colder areas of the suburbs (such as Orange/Putnam Counties and the LI Pine Barrens) could see freezing conditions Sunday morning as a 1036mb high pressure crests over the region with 850s around -5C for NYC metro. For Southern Westchester, at least a light frost is likely. Here is the 18z GFS at 90 hours showing the frosty morning: Link to comment Share on other sites More sharing options...
Guest Pamela Posted April 18, 2013 Share Posted April 18, 2013 The green-up here is usually between May 1st and May 10th...last year's was the earliest I can recall, taking place by mid-April...this year's looks to be within the normal range...when I lived in Plainview...it averaged about 5 days earlier.

earthlight Posted April 18, 2013 Share Posted April 18, 2013 We had major budding here this week. As William said the big green up usually doesn't come until the first week of May...so I don't think we are behind schedule just yet. Link to comment Share on other sites More sharing options...

A lot of my front lawn is in the shade for 90% of the day so that might have something to do with it. The same spots that are the last to lose the snow pack are usually the last to turn green.

IsentropicLift Posted April 18, 2013 Author Share Posted April 18, 2013 Maybe this will spark some discussion.... Has a PDS watch box ever been issued anywhere in the northeast? Should PDS watch boxes be issued for standard severe thunderstorm watches such as in the case of a derecho like the mid-atlantic saw last year? Are thunderstorm watch boxes and warnings over used and has this led to a state of complacency? Link to comment Share on other sites More sharing options...

Are thunderstorm watch boxes and warnings over used and has this led to a state of complacency? Yes there have been PDS boxes in the Northeast There have been many PDS severe thunderstorm watches for widespread damaging wind potential I don't think they are over used, I just don't think the public totally understands what they mean which is pretty sad.
