BrooklynSnow Posted September 13, 2011 Share Posted September 13, 2011 So I love the first feel of crisp fall temperature. And to my delight NWS is showing a potential low temp of around 50 this Friday and Saturday. What is the chance of KNYC really bottoming out at or below 50 this week? Thursday Night: A slight chance of showers before midnight. Partly cloudy, with a low around 50. Chance of precipitation is 20%. Friday Night: Mostly clear, with a low around 50.

MJO812 Posted September 13, 2011 Share Posted September 13, 2011 I will say low to mid 50's. Link to comment Share on other sites More sharing options...
Stormlover74 Posted September 13, 2011 Share Posted September 13, 2011 9/16/07 was the last time temps dropped in the 40s this early. EWR got down to 47, but Central Park bottomed out at 50. I would say unless guidance is showing 43-45 it probably won't happen. Link to comment Share on other sites More sharing options...

Quincy Posted September 13, 2011 Share Posted September 13, 2011 I say they stay in the 50s...mid-50s Friday morning, perhaps lower 50s Saturday morning as NW winds die off. Link to comment Share on other sites More sharing options...
SnowGoose69 Posted September 14, 2011 Share Posted September 14, 2011 Here are 3 setups in the last 30 years that produced record lows at NYC in September The 1986 and 1990 setups had a colder airmass. 850 temps were near 0C ove NYC. 1993 was closer with 850s of 3-5C. I think 47 or so is possible. Not sure if Friday AM will be the colder morning. The GFS says so with a low of 48 but the gradient will be weaker Sat AM. 9/17/86 - 45 http://www.meteo.psu.edu/~gadomski/NARR/1986/us0917.php 9/18/90 - 44 http://www.meteo.psu.edu/~gadomski/NARR/1990/us0918.php 9/20/93 - 44 http://www.meteo.psu.edu/~gadomski/NARR/1993/us0920.php Link to comment Share on other sites More sharing options...
NEXtreme Posted September 14, 2011 Share Posted September 14, 2011 NWS is now forecasting NYC to get down into the mid to upper 40's for two nights. Link to comment Share on other sites More sharing options...
tacoman25 Posted September 14, 2011 Share Posted September 14, 2011 The airmass is already producing record lows in the upper Midwest. We'll see if that holds as it progresses east. Link to comment Share on other sites More sharing options...
Stormlover74 Posted September 14, 2011 Share Posted September 14, 2011 It may particular away from the coast and urban areas. Just seems like getting the cities to drop is like pulling teeth this time of year. I expect to see some quite large anomalies between the far NW burbs and EWR/NYC, Could be a situation where the cities hover around 60 late tomorrow night while its already in the 40s well north and west. But both the NAM and GFS show pretty large temperature drops in the neighborhood of 20 degrees or so between 18z and 0z tomorrow. The airmass is already producing record lows in the upper Midwest. We'll see if that holds as it progresses east. Link to comment Share on other sites More sharing options...
tornadojay Posted September 15, 2011 Share Posted September 15, 2011 I would be very suprised if the city dropped below 50. With 850's pretty much the same both tonight and Friday night and the city not prone to much of any readitional cooling affects, I expect overnight lows to be similar both nights.. somewhere in the 52-54 range.
