Monday Evening Upcoming Storm(s) Weather Update

Updated: 0100z/20:00/08:00PM
FORECAST
TONIGHT - Pretty much clear, lows in the low teens to single digits maybe in far northern and northwest areas of NY and New England.
TUESDAY - Clear skies will give way to thickening clouds, temperatures in the high 20's to right around 32°, Snow and sleet developing in the LATE afternoon (SEE SNOW MAP), 1-3" (could change, but we doubt it) into the evening and nighttime.
TUESDAY NIGHT - Snow/sleet changing over to ice/sleet/rain and finally all rain by Wednesday morning, nighttime temps around freezing...WATCH out this could be a SERIOUS ice situation as ground is frozen, and a lot OF cold air around...
WEDNESDAY - Ice/wintry mix changing over to all rain in the morning (around rush hour probably maybe a bit sooner/later) will continue throughout the morning, may be a bit heavy at times... Should be a lull in the precipitation during the afternoon as the Initial [storm] moves out then starting again in the evening. Temps in the high 30's to low 40's.
THURSDAY - We have a BIG potential to waking up with NEW snow on the ground and snow falling, as a new wave forms off the back of the Lake Cutter and comes through Wednesday Night through Thursday afternoon/evening...We WILL have cold air in place and this could be a BIG storm...we will keep you posted.
FRIDAY - COLLD Rapid freez up Thursday night, Highs in the low to mid 20's, mostly sunny.
FORECAST DISCUSSION
We have a VERY wild week ahead! A bit of a break today and most of tomorrow before our next storm arrives. A lake cutter will form and move across the area. Since the Center of the Low pressure will be FAR to the N and W of us, it will be a mostly rain event - HOWEVER, we have plenty of cold air in place so watch out for a big THUMP of snow Tuesday evening into the night 1-3" locally 2-4" before a changeover to rain/sleet/ice into Wednesday morning then all rain Wednesday. NOW the interesting part - a brief lull in the precipitation HOWEVER, bucket loads of moisture with this system, and the models have been insistant on another wave forming along the Arctic Frontal Boundary. Cold front will come through Wednesday night, new shot of colder air, and a new wave will form to the SW of us and move ALONG that frontal boundary towards us. THIS would be our all snow event, or Rain to ALL snow event starting Wednesday night and lasting through Thursday Afternoon likely. At this point accumulations could be anywhere from 5 to 10" although that could change. WHEREVER this front boundary sets up is where the axis of heaviest snows will be. If I take an average from ALL the 6 models with snowfall maps, that gives NYC metro area and northern Suburbs 6-8" snow. A wet heavy snow too.
So keep an eye out for our posts - wild week ahead. More cold for Friday as well with a flash freeze Thursday night.
***THE SNOW MAP IS ONLY FOR TUESDAY NIGHT THROUGH WEDNESDAY MORNING***

HAVE A GREAT NIGHT!
