April 9, 2016 Snow Event.


Bernie Video . Good video for all but mostly for weather geeks I guess.


I didn't realize an upper Low was coming over the area. My favorite feature! The lift associated with it can be impressive "in spots". Where will those spots be?? I will post the latest Vertical lift projections later.

The NWS is predicting a low of 26 F/-3 C for me Saturday night. I hope that doesn't cause leaf damage.

I see Pear and Cherry blossoms waking up now. Strange after the cold but I guess they liked the drink of downpours. Wonder if they will be killed too like the Magnolias

..........Geek Alert..........


NAM18z Vertical Velocity. Different on GFS and Euro.. It's a "detail" so take it with a grain of salt being that it will and can change even day of.

Basically the Reds and Pinks are where the snow is thumping away.. HEAVY snow, the areas where it will accumulate much easier in April. Light snow is going to be tough IMO!

So the VV is basically the "lift" in the atmosphere, the vertical wind speed. Rising air leads to precip. The stronger it is, the heavier the precip will be. Downward air leads to nothing.


So latest NAM projects Saturday 8am that the heaviest snows will be around Philly and Atlantic City. I say snow because I looked at the other maps as well.





Then that shifts north as morning goes on and at 2pm here is where it says the heavy snows will be. BTW .. it has NO SNOW in CT. Ignore the yellows there because there's no precip.


That's why you have to look at so many parameters to make a forecast. It's a tough job! And what model do you believe?

Where else would the artic air go? The NE of course!

The only consolation is that the average highs now are still around 10c so it's not like we're missing out on a bastion of warmth here...still by the end of the month the average highs will reach a comfy 15c so I want the end to be seasonable at least!

That thunderstorm band near Albany is coming towards us, weaker though.
