Isotherm Posted February 7, 2015 Share Posted February 7, 2015 Last 0 degree day here was Jan 2004...last below 0 was Jan 1994. I had -1.7F last winter in early January, and before that in January 2011. I also believe January 2009 I slipped below 0. Link to comment Share on other sites More sharing options...
forkyfork Posted February 8, 2015 Share Posted February 8, 2015 If the 12z GFS is anywhere near correct, NYC will finally get to zero: nyczero.gif the extent of the -20C isotherm has been cut back with each model run... 0 isn't going to happen with 850 temps barely below -20c Link to comment Share on other sites More sharing options...
tmagan Posted February 8, 2015 Share Posted February 8, 2015 the extent of the -20C isotherm has been cut back with each model run... 0 isn't going to happen with 850 temps barely below -20c I have no idea why the NWS is calling for lows between zero and five for Thursday night for NYC.

uncle W Posted February 8, 2015 Author Share Posted February 8, 2015 There was a thaw for a few days right after that cold streak and then it turned very cold again. My father was born in February, 1918. Many years ago, when I was a kid, my grandmother told me of when she was pregnant with my dad (in Brooklyn). She told of it being very cold and then it warmed up for a bit before everything froze up again when she was eight months pregnant. She fell on the ice then and was very worried that she'd lose her baby. Thank God she didn't (lose her baby) or else I wouldn't be here. Anyway, I had once looked up the weather reports for that period and they backed up my grandmother's story. I love when that happens. my uncle was born on 12/8/1917 and passed in 1999 had to be put near the oven to prevent him from turning blue...That's the story my aunts used to tell me...My mom used to tell me about the time she was pregnant with me and fell in the snow during the blizzard of Dec. 1948...she was worried also...I grew up listening to stories about the big snow of 1947...maybe that's why I like snow so much?...

My grandma always talked about the 47 storm as the big one. She had great pictures of the snow in garden city. I always wondered about that storm. Was it a miller A or B?

uncle W Posted February 10, 2015 Author Share Posted February 10, 2015 when a model is showing record cold five days out reg flag it...it doesn't mean it ain't getting cold...I usually add 5-10 degrees as a rule of thumb... Link to comment Share on other sites More sharing options...
doncat Posted February 10, 2015 Share Posted February 10, 2015 Looks like we can string together several straight single digit lows from Friday morning thru Monday morning and maybe Tuesday...coldest looks to be Monday, flirting with 0 maybe?

doncat Posted February 10, 2015 Share Posted February 10, 2015 it could happen in Travis...add 5-10 degrees for Central Park...Yes true ...it will be a pretty impressive cold spell though. Its always bothered me that official temps can be taken in a known UHI location...to me its an artificially influenced temperature...it should be taken in a natural environment...but that's just me..rant over..lol Link to comment Share on other sites More sharing options...

JBG Posted February 15, 2015 Share Posted February 15, 2015 Central Park is more natural than much of NYC and probably has lower temperatures than many other parts of the City.Could the forestation of Central Park be limiting nighttime lows the same way it cuts the number of 90's and 100's during the summer?

Doubtful no leaves on the trees in winter. Speaking of which I took a walk through the north woods yesterday. Now that is an incredible place Link to comment Share on other sites More sharing options...
tmagan Posted February 15, 2015 Share Posted February 15, 2015 From what I can see, Central Park from the date of February 16th or later has gone below zero twice. Link to comment Share on other sites More sharing options...
JBG Posted February 17, 2015 Share Posted February 17, 2015 From what I can see, Central Park from the date of February 16th or later has gone below zero twice.So harder to get a subzero date this late than a 100 degree day after August 16?

yhbrooklyn Posted February 17, 2015 Share Posted February 17, 2015 There have been sixty 100° days and fifty-seven below 0° days in Central Park. But, there have been 35 of the former and only 8 of the latter since 1950. Link to comment Share on other sites More sharing options...

Also the 1910's stand out for an unusual amount of subzero weather, and the 1950's for 100+ weather. Link to comment Share on other sites More sharing options...

Yeah, UHI for sure, but the 50s and 10s definitely stand out. Link to comment Share on other sites More sharing options...
Guest Pamela Posted February 17, 2015 Share Posted February 17, 2015 above100.jpg From January 1, 1960 through December 31, 2014 there have been 20,075 days (not including days added for leap years)...the figure shows 23 days when the temperature reached 100 F or better. That means the mercury eclipsed the century mark about one out of every 873 days...so it is not a very common happening...even if it is a fraction more frequent than earlier in the climate record.
