Tuesday Evening Winter Storm Update

Updated: 0030z/19:30/07:31PM
*****Emergency Alert for the Period NOW until Tomorrow Morning*****
Guys Obviously this front thump of snow has overachieved in everyway. Currently recording almost 5" at my house, and a friend in White Plains has the same recording. White Plains Airport is at 4.9" officially as of 7pm.
Please, please be careful - now we are changing over to an Ice/Freezing Rain/Sleet Mix and it will stay like this for the next SEVERAL hours before changing to plain rain around or after midnight.
Anymore Accumulations should be between 1-3" of this mess, maybe a bit more.
FORECAST
TONIGHT - ICE/freezing rain/sleet/snow continuing before changing over around midnight to rain. Additional Accumulations 1-3" if not more. Temps around freezing.
TOMORROW - Rain and dense fog, rain may be heavy at times in the morning, but doubtfull. The GROUND will be below freezing so WATCH out for Ice!!!!! GONNA be a really MESSY morning.
A lull in the precipitation as cold front comes through and storm pulls away, our second wave forming.
TOMORROW NIGHT - Rain turning to ice to all snow by midnight and continuing, temps in the mid to high 20's.
THURSDAY - Snow in the morning through afternoon tapering off in the evening. Could be significant accumulations. Temps in the high 20's.
FRIDAY - Frigid watch for rapid freezup highs in the low 20's.

FORECAST DISCUSSION
A rapidly deepening low pressure system will continue to move across Southern Canada and take over with rain after midnight tonight. As it pulls out tomorrow a wave will form off the bucket loads of moisture along the frontal boundary (cold/warm air) Where this frontal boundary will determine the exact trend of the heaviest snows, but it seems that the Arctic Air coming behind it will be enough to suppress the axis of heaviest precipitation along NYC to Philly. We would once again be on the northern edge of the heavy (ish) snows. Right now I am calling for 3-5" with a possibility of going down and up. Dillon thinks 1-2". What should be noted is that as the storm intensifies, much like today, the snow ratios will bump up especially from the air rapidly cooling. We can expect 12:1 ratios and maybe 15:1 if lucky. Also keep in mind that the heaviest snows are NYC to Philly - NYC is less then 30 miles away. It would really not take MUCH for us to get in the heavier snows again. An example is that Yonkers has a Winter Storm Warning for 4-8" of snow, and here in Irvington we have no warning and just 2-4" of snow. Not far to move!. however as of now this is the forecast. You could say Dillon scored a "coup" I still have my doubts though!
This second half of the storm should continue into Thursday afternoon and evening. Initial first call snow map is below.
Guys, even if we do not get 8-12" with the next batch of snow - it will be very icey, very dangerous tomorrow into Thursday afternoon. This is NOT a storm to take lightly, especially because of its long duration.
Ok thats it for now! Be back later if need be
