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

**********8PM Update Monday**********

Total snow for today was 2.9" - on the LOW side of our 2-5" Forecast, but still within that. Boston on the other hand, and areas around there - THEY are the winners. Approaching 6-7'+ of snow on the ground up there!!

*********************************

Rest of the night should start to clear out a bit, any light snow/sleet/ice will end by midnight. Temperatures will go down in the Highs teens/low 20's.

TOMORROW - Clouds will continue to clear out, Highs around freezing, WATCH for ice that may have formed overnight.

WEDNESDAY - Mostly Sunny, Highs in the High 20's to very low 30's.

THURSDAY - Next possible storm? Could evolve into a biggie, but for now 2-4" ish of snow late Thursday through Friday morning. Watch this carefully though because we could be in for a big storm.

Next storm after that would be for the weekend, and also could be a BIG one.

INTENSE, BRUTAL and coldest air of the season coming starting Thursday into the weekend. Highs could possibly barely reach the 20's, with lows well below 0°. We shall know specifics later, but seriously cold air coming.

********************************

Have a great night guys!!!

**********10:45 AM UPDATE ON WINTER STORM LINUS [#LINUS]*********

VERY VERY HAPPY WITH THE FORECAST THAT DILLON AND ME PUT OUT LAST NIGHT, VERY HAPPY. 7.58" SO FAR, NO RAIN YET JUST SLEET AND ICE AND SNOW. 

The storm ended up coming in a tad weaker and was not able to push that Arctic HP as much away, therefore cold air lasted longer.

SO WHATS NEXT?

We have a Secondary low trying to/succesfully ish forming off the Delmarva Peninsula (Well really between Jersey Coast and Delmarva) and THIS will drain some more cold air south and fuel a redevelopment of precipitation as the two fronts collide LATER THIS AFTERNOON.

SO...SLEET, ICE, SNOW will CONTINUE for the next few hours AND THEN a POTENTIAL HEAVY BAND OF SNOW WILL DEVELOP AFTER LUNCH AS THE BACKSIDE OF ALL THIS MOISTURE WRAPS AROUND and the Secondary low moves NE. 

REST OF TODAY - Snow/Sleet/Ice continuing and then turning back to an all snow solution after lunch for a TIME. SNOW COULD BE HEAVY. Additional accumulations of 1-4" ARE POSSIBLE as that heavy band comes through, WE WILL UPDATE ACCORDINGLY.
Temperatures in the High 20's in NYC to Low 20's in Westchester and PROGRESSIVELY colder as you get N/NW/NE of NYC. IMMEDIATE COASTAL AREAS - MORE OF A RAIN/SLEET MIXTURE.

FLASH FREEZE IN EFFECT FOR THIS EVENING, TEMPERATURES DROPPING 20-30° FOR SOME TO LOW TO MID TEENS OR UPPER SINGLE DIGITS. ALL STANDING WATER, MELTED PRECIP, UNTREATED ROADS, ETC WILL FREEZE

All precipitation will taper off this evening into nighttime and gradually clear by midnight.

PLACES SOUTH OF YONKERS, COASTAL CT, LONG ISLAND...YOU WILL HAVE A POTENTIAL COMPLETE MESS OF ICE ON YOUR HANDS AS TEMPERATURES RAPIDLY DROP AND MOISTURE MOVES IN, PRECIP KEEPS FALLING. BE CAREFUL

Additional Snow accumulation map below.

ANY QUESTIONS? IF SO POST IT BELOW IN THE COMMENTS OR MESSAGE ME OR DILLON.

********11PM UPDATE ON WINTER STORM [LINUS?]*********

Snow Has started moving into the area, the ACTUAL system still WAY back in Western PA. The storm looks to be tracking a TAD south of what was thought - GOOD for snow lovers. Models continued to trend south a tad as well, only like 5-10 miles...but any trend is a good trend south.

IT WILL STILL be a close call with rain/snow line - WE ARE EXPECTING A POTENTIALLY SERIOUS ICE SITUATION FOLKS! Looks like at this point we cannot get out of that! UP TO A HALF AN INCH of Ice COULD ACCUMULATE ON TOP OF 5-8" OF SNOW! BE CAREFUL FOLKS!

So, Looking like a GOOD 6-9 hours of SNOW before we start thinking about changing over to wintry mix.

PERSONAL OPINION FROM DILLON AND I - BAD IDEA FOR SCHOOLS ON TWO HOUR DELAY, GOING TO BE VERY VERY ICY AND BAD ROADS/CONDITIONS TOMORROW. LETS HOPE THEY CHANGE THEIR DECISION.

BACK TOMORROW MORNING WITH UPDATES.

STILL HANGING ONTO SNOW ACCUMULATION MAP FROM BEFORE.

*********************QUICK Sunday Afternoon Update!**************

The GFS and the NAM have continued their northward trend since yesterday, meaning that there is the chance of less snow and more mixed precipitation especially during the height of the storm on Monday. However, this means SIGNIFICANT ICING is becoming increasingly likely, which is much worse than an extra few inches of snow. For now, though, Remy and I will keep our forecast from last night and will re-post the snow/ice map we made yesterday as the European and Canadian models from midnight are sticking with significant snowfall for the area. Based on some of the data right now, the GFS and the NAM may be too warm with the storm, and they might head towards a solution closer to the European and Canadian models later in the day. Our current snowfall map is more of an average between the four models. We will follow this storm throughout the day and post again later on this afternoon around 5:00 PM when the next model runs come in.

Here is yesterday's snow map, which (for now) still applies:

********EVENING UPDATE******

I am happy to say that the snow amounts that I forecasted came out more or less right on target! I knew that there was too muhc cold air here that it would be all rain today  silly weather sites  

SO,.. Here is the deal! Forecast for the rest of the night and tomorrow:

TONIGHT - Snow/Sleet will turn to Sleet and then ALL rain by 9pm for pretty much everybody south of Albany. Peoples North of Albany and Concord, NH expect it to stay an icey/sleety/snowy mix until late tonight before changing over to all rain. Temps will rise to mid to HIGH 30's.

TOMORROW - WOW MUCH WARMER! I dont think nearly as warm as some are saying (61*!) BUT we will definately get up into 50's, and possibly break that 60* mark, but probably only for folks SOUTH of I287/Thruway.

MONDAY - First cold front moves through Sunday night finish up its passage Monday, temps in the mid 30's, partly cloudy.

GETTING INTO TUESDAY We have an Alberta Clipper that will MOST LIKELY affect us Tuesday afternoon into evening. Since Alberta Clippers are fast and hard to predict until they are basically on our doorstep, we will get into this Monday night!

Latest Radar image below!

****MIDDAY UPDATE FOR THE STORM****

Snow Still falling at a good clip here in Irvington, expect it to stay as a Snow/Sleet mix for the next several hours for ALL areas NORTH of I95/I84 before changing over to an Icey rain to all rain by nightfall. Unless you are FAR north, WELL north of Albany, do not expect it to stay as snow past dinner time.

TOTAL daytime accumulations 1-2" and MAYBE 1-3" in the hills, Elevation dependent. 

Warm air starting to surge in as you can see on the image I have posted below..expect temps to go up into the mid to high 30's as it changes over to rain. Tomorrow HIGHS in the low to mid 50's. Rain. MORE ON THIS TONIGHT.

Have a great day!
