As many of you know we were expecting a light to moderate snow event for NYC North Jersey and the whole area with a general 1-3 inches, but mother nature had different plans as has been the case an awful lot this winter.
The plan was an arctic cold front will come east , while a weak coastal low would enahnce precipitation along the mid Atlantic coast and NE, not a major snow but a swath of light to moderate snow.
The problem was that we were counting on heavy precipitation to cool down the lower atmosphere wich did happen last night and thus we if you woke up at 6 am there was a coating to 1 inch on the ground, butit was night time so it was easier to cool it down, and it cooled down to 30-32 with just some light precip. But the problem was, that the coatal low was a tad SE of where it was supposed be and so was the heaviest snows.
In February we start getting a much higher sun angle so its hard to get stickage unless its a big storm with heavy precip, like down in Philly metro they were able to overcome the sun angle with heavy precipitation and they got a widespread 1-2 inches there because the heavy snow held down temps around 32 so it was able to stick to the grassy surfaces easier. Theres not much of a cold air mass in place so as soon as the precipitation ended down there temps rose into the mid 30s
Meanwhile in NYC/North Jersey there was only light to moderate precipitation so once the sun came out temps were able to rise above 32 rather quickly so not only couldnt the snow stick, but the snow on the ground was able to melt as temps rose to 33-34-35 and eventually 36 and 37 for a time again, we were counting on heavy precipitation to keep the temperatures down as there really wasnt a cold air mass in place to begin with. So instead of getting 1-3 inches we got a coating to an inch that melted away as soon as the sun came up despite the fact that snow was falling, the only reason snow was falling was because the upper atmosphere was very cold and the snow flakes were able to make it to the surface.
Here is the current radar and you can see the coastal low and its precip field going NE rather quickly, BUT the arctic cold front is still over PA and theres some decent snow squalls and rapidly falling temps with this snow shield, so IF everything goes right and this precip makes it this far east we could see a quick 1-2 inches on grass with very windy conditions and rapidly falling temperatures, ill be keeping an eye on this, I do think there will be some snow showers later this afternoon tonight as the cold front comes through but we have to keep an eye on temps, timing and intensity as it comes east.
