NorthShoreWx Posted February 25, 2015 Share Posted February 25, 2015 Radiated nicely early this morning and we got down to 10 (9.8). That is sort of like another single digit night although I recorded 10. Link to comment Share on other sites More sharing options...

Isotherm Posted February 25, 2015 Share Posted February 25, 2015 After today ...averaging 21.6 here for the month...coldest Feb on station record is 22.5 in 1979 and coldest month overall is 20.5 in Jan 1977. Through today I have a mean temp of 22.3F, mean max of 32.9F and mean min of 11.7F. I've had 12 days with minima temperatures below 10 degrees, 2 of which were sub zero. Lowest -5F, the coldest I've recorded on my station since installing in 2007. On the 20th I had my lowest mean temp I've recorded: 8.9F. High was 17.6 and a low of 0.1. Departure of -11.5 thus far. We have some good radiational cooling nights coming up Fri and Sat nights which should be well down into the single digits. Link to comment Share on other sites More sharing options...
tdp146 Posted February 26, 2015 Share Posted February 26, 2015 The sharper satellite image today does a better job of showing the ice build up on the area waterways. Significant ice floes on the Long Island Sound can be seen more clearly today. The ice between Nassau and the Bronx is also very impressive. There are probably some great photos to be had looking east from the Throgs Neck Bridge. Screen shot 2015-02-25 at 1.17.45 PM.png Great South Bay is pretty locked up. You can see where "new" old inlet from sandy is actually keep the back end of the GSB open. I would imagine the ice will reach its maximum this weekend before slowly easing into March.

chietanen Posted February 27, 2015 Share Posted February 27, 2015 NYC is currently in third place for the coldest February with a strong cold finish expected in the daily departures for Friday and Saturday.

cjr231 Posted February 27, 2015 Share Posted February 27, 2015 That 24.0 is going to look so out of place for 2015 when its placed on that chart. Similar to the 1934 drop off. Link to comment Share on other sites More sharing options...

chietanen Posted February 27, 2015 Share Posted February 27, 2015 The current February average temperature in NYC is 35.3. The 1901-1930 30 year average for February was close to 30.8. The chart below illustrates the steadily rising February temperatures in NYC since then. Screen shot 2015-02-21 at 8.50.45 AM.png Hypothetical question, but is it safe to assume that this airmass, had it occurred in 1934, could have possibly been even colder than as it occurred in 2015?

SnowGoose69 Posted February 27, 2015 Share Posted February 27, 2015 Assuming NYC finishes this month at exactly 24.0, had December simply averaged 33 or less it would have ended up in the top 10 coldest winters easily. Link to comment Share on other sites More sharing options...

NorthShoreWx Posted February 27, 2015 Share Posted February 27, 2015 that's not how it works Perhaps, but wouldn't that line be more accurate if wasn't a straight linear regression? If we did a regression on NYC snowfall data though about the early nineties, it would probably project out to less annual snowfall than Atlanta by about now. It doesn't work that way either. These lines are curved. Link to comment Share on other sites More sharing options...

These lines are curved. Agree. Most of the warming occurred in the early part of the 20th century for NYC, from the 1900-1940 period. If we started the regression toward the mid point of the 20th century, the warming trend would be significantly less. Link to comment Share on other sites More sharing options...
FreeRain Posted February 27, 2015 Share Posted February 27, 2015 that's not how it works No, not at all. One could start a regression analysis using data at any starting point. The above graph uses 1900 as a starting point. As I said, if one uses 1981 as a starting point then the temperature trend line for Feb. in NYC would be decreasing.

FreeRain Posted February 28, 2015 Share Posted February 28, 2015 Why would you use 1981 as a starting point when when the poster was asking me about what the average temperature was in NYC from 1901-1930 compared to today? Why would you use 1981 as a starting point when when the poster was asking me about what the average temperature was in NYC from 1901-1930 compared to today? All the top ranking cold years were in the late 1800's and early 1900's. What? I never said that one should use a starting point of 1981 if one is talking about drawing a trend line from 1900 to present. Link to comment Share on other sites More sharing options...
Guest Pamela Posted February 28, 2015 Share Posted February 28, 2015 The chart below illustrates the steadily rising February temperatures in NYC since then. Your verbiage not only implies...but clearly states, that temperatures have been steadily rising since then...which implies that the increase in temperature is continuous from then until now (the use of the word "since" is elemental to this conclusion); which it clearly is not.
