Monday Night Update - Snow Coming tomorrow!

-
Updated:0230z/22:30/10:30PM
---------------------------------FORECAST-----------------------------------
TONIGHT - A few scattered showers possible, maybe some snow flakes coming down. Lows at or below freezing for most.
TUESDAY - Alberta Clipper here it comes! Cloudy morning will give way to a light snow by early afternoon lasting through to the evening hours most likely. See maps for details. Highs in the low 30's in the morning getting up to around 40° but watch out that will quickly drop back to 30's in the evening and nighttime.
WEDNESDAY - Sunny highs low 40's
THURSDAY - a few clouds otherwise nice, highs in the high 40's..possibly making it into the 50's with southerlies and down sloping.
--------------------------FORECAST DISCUSSION------------------------
Winter just keeps wanna coming! But dont worry! Serious signs of a pattern change to a more spring like feel starting after April 10-13th...FOR NOW wink emoticon.
An Alberta clipper will affect the area tomorrow. NOW, couple problems with this, FIRST it will be snowing during the afternoon mostly when the sun is at its strongest, secondly temps will be marginal. SO...right now the accumulations on the map are for GRASSY, UNPAVED surfaces...driveways..etc. MAIN Roads will probably not get messy with this. A general 1-3" for the NYC northern Suburbs, more to the West. See map for details. This being said, looking at the progs Dillon and I are worried about some "thumping" as there will be good dynamics with this system, strong northerlies aloft ramming the warm air into cold creates strong uplift and will enhance the snows. High lapse rates indicate this as well. Not a big storm, but not a little Clipper..
Still worried about snow for Easter Weekend. Now whether it changes to rain after snowing a bit is a question that needs to be answered...but do not put away your shovels yet. GFS is still hanging onto a snow situation as it has been for 4-5 runs now...so definitely something to watch for. The Euro has been sticking with a Lake Cutter, but the latest run (12z) showed a big fungdungle of a mess going on that has no clear "idea" to it, more like many ideas in one....so maybe a trend to something else we shall see what happens tonight.
Another couple storms after that possible next week...rain or snow or both cannot be figured out yet it is too far out.
HAVE A GREAT NIGHT!
