uncle W Posted January 25, 2013 Share Posted January 25, 2013 it's a cold week but far from the coldest weeks ever... I looked at over 25 cold spells for at least one week in NYC since 1876...Hoping my math and dates are correct I came up with this top 15...ave temp...month/day/year...02.5......12/29/1917-1/4/191808.8......2/8-14/189910.9......2/3-9/189512.2......1/6-12/196812.3......1/11-17/189312.6......12/28/1880-1/3/188112.7......2/12-18/197913.5......2/4-10/193413.5......1/22-28/188813.6......1/9-15/188613.6......1/10-16/191213.9......1/15-21/199414.1......2/1-7/188614.6......1/15-21/193514.6......1/23-29/1936......................Some recent years...15.5......1/20-26/196115.9......1/12-18/197716.1......1/13-19/195716.7......2/13-19/195817.0......1/18-24/2005the late December early January cold spell in 1917-18 is by far the coldest week in recorded NYC weather history...It averaged 2.5 degrees...The February 1899 cold spell comes in second with 8.8 degrees...1968 and 1979 made the top ten and 1994 the top 15...Temperatures like this for a week cause many problems...Frozen pipes and dead battery weather Link to comment Share on other sites More sharing options...
PB GFI Posted January 25, 2013 Share Posted January 25, 2013 No problem. January 2005 doesn't really stand out in peoples minds after January 2004 was so cold around here. 04 - just stuck out because it was really a brutal 3 week period , with a small bump in the middle . and that was my 1st yr in Laurel Hollow .

bluewave Posted January 25, 2013 Share Posted January 25, 2013 04 - just stuck out because it was really a brutal 3 week period , with a small bump in the middle . and that was my 1st yr in Laurel Hollow . Today we'll get the fourth -10 or lower temperature departure in a row that you were mentioning last week which has been so rare recently during winter months here. We got to 5 days in a row in February 2007 but have been having trouble getting past three since then. I guess sooner or later were were bound to get a cold wave that exceeded the model forecasts from a week out. Link to comment Share on other sites More sharing options...

Allsnow Posted January 25, 2013 Share Posted January 25, 2013 Just curious how you (or someone) arrived at that. Is that a projection based on expected temps through Saturday or Sunday and is it based on some aggregate temperature deviation or some other measure? Been wondering how this cold snap rates, historically, and how cold snaps are even ranked. Any info would be appreciated... Lonnie Quinn said it on Ch 2. I don't know how he arrived at it.

RU848789 Posted January 25, 2013 Share Posted January 25, 2013 This week won't turn out to be colder than during January 2005, but will be among the coldest since then. Coldest weeks in NYC since 2003: 1/18/-1/24......2005....17.1 1/10-1/16......2004.....17.4 1/18-1/24.......2003....18.7 1/23-1/29.......2004....18.9 2/4-2/10.........2007....20.9 1/15-1/21.......2009....21.2 Looks like this one week cold snap will probably be the coldest since 2004, which is decent, but I assume it's maybe top 25-30 or so, as it's well behind #15 in uncle W's list. Allsnow - gotta agree with the others that Lonnie Quinn is a moron, lol. Unless he's calculating "coldest" in some other way. One would think average temperature over a given timeframe is the best measure, but maybe they're just looking at coldest high temps for a stretch, or something, since it seems like the low temps are more affected by the UHI than the "low" high temps per day (based on my gut instinct, not any data).

It looks like we may come in at around 21.4 from Monday to Sunday, but we'll check it when we get the final numbers. That would be close to the coldest weeks in 2007 and 2009. 2/4-2/10.........2007....20.9 1/15-1/21.......2009....21.2 Link to comment Share on other sites More sharing options...
