A brief weather forecast and a Happy New Year!

Well, 2010 is almost over and in a few hours, 2011 will begin.  It's been a wild year for weather across the world.  From blizzards to hurricanes, and from floods to droughts.  For us here in northern NJ, 2011 will begin with some warmth.  High pressure is anchored to our south and will serve to push some warm air in from the Gulf.  For the next 3 days, as the High Pressure slowly moves east, we will see temperatures continue to climb to the upper 40's.  The average for this time of year is around 31 degrees!  That is certainly some welcome news to those whose streets have yet to be plowed in NYC or those of us with 7ft piles of snow on our lawns!  However, all good things must come to an end and, for this heat, it will end on Monday.  A cold front will push through the region on Sunday bringing with it rain and some wind.  This could cause some flooding in areas where drainage sewers are still blocked by snow mounds so be aware.

Until then, I wish everyone a Healthy and Happy New Year!

Final Snow Totals and Post-Blizzard Recap

Ok so that was a wild storm! Here, in Belleville, NJ, we received 24.8" of snow! That would make it one of the top 5 snowstorms for our area! Elsewhere we have seen snow totals around the same depth.

Elizabeth: 31.8"
Lyndhurst: 29.0"
Clifton: 25.0"
Bloomfield: 24.5"
Newark Airport: 24.2"

Union County appears to have gotten the worst of this storm, with many towns reporting snowfall amounts of 30"+.

This storm wasn't just about the snowfall.  The wind was also a major factor.  As we all know, it's the wind that separates a blizzard from a major snowstorm.  The definition of a blizzard courtesy of the NWS:
 A blizzard means that the following conditions are expected to prevail for a period of 3 hours or longer: 
  • Sustained wind or frequent gusts to 35 miles an hour or greater; and
  • Considerable falling and/or blowing snow (i.e., reducing visibility frequently to less than ¼ mile)
Wind gusts were reported at Newark Airport as high as 51 mph.  In Long Island, Nassau and Suffolk Counties reported wind gusts as high as 68 mph!  Power has been knocked out to 1,300 PSE&G customers in NJ as a result of downed power-lines.

This storm has completely disrupted travel plans across the area.  All three major airports have been and remain closed.  Newark and JFK Airports will reopen at 6 pm, while LaGuardia Airport has yet to announce a time to reopen.  Trains have been suspended as well until the tracks can be cleared.  If you are traveling by car, many roadways were closed for cleanup this morning but have been reopened since.  I suggest if you don't need to be on the road than stay off the roads.

I leave you now with a cool time lapse video of the Holiday Blizzard 2010.  This was taken by Michael Black from Belmar, NJ, where they reported 32" of snow.   Holiday Blizzard 2010 Time Lapse

NJ Under Weather State of Emergency and snowfall totals....

12:00AM: 
                Acting Governor Stephen Sweeney has declared a Weather State of Emergency for tonight and tomorrow.  He is advising all non-essential employees to stay indoors.  No word yet on whether state offices will be closed for Monday.  "It is vital that police and public works crews are able to do their jobs. I urge all residents to take this declaration and this storm seriously, and to stay safe, stay home and stay off the roads. We will continue to monitor this storm with the help of our State Police and transportation officials," Sweeney said in a press release Sunday.


One of the measurements taken at 11:40pm
I had just ventured outside to take another measurement and, believe me, it is not safe outside!  Again, I took several different measurements around the area.  The highest non-snowdrift depth was approximately 21.3" and the lowest non-snowdrift depth was 17".  The average snowfall depth so far is 19.4".  The timeline for this storm remains the same.  The Low Pressure center is approximately 100 miles east of Atlantic City and is slowly moving North-Northeast and will continue on that track overnight.  The snow should begin to taper off between 4am-5am; however, the blizzard conditions will remain issued until 6pm Monday afternoon.  This is because the winds will maintain strength tomorrow and continue blowing snow throughout the day causing reduced visibility.  With 19.4" already on the ground and another 4"-5" to go, we could be waking up to snow depths over 2 feet!  Be careful overnight!

Blizzard 2010 UPDATE 7:50pm

22" snowdrift outside of my house!
Well, the last few hours brought quite a change to the area.  It is tough to measure the actual snowfall total in a storm like this because of snow drifts.  Snow drifts can be very extreme.  With winds gusting as high as 50mph in the area, these snow drifts can certainly pile up quite high.  I had measured a snowdrift just a few minutes ago of 22" in the front of my house.  In order to best eliminate the anomalies of the snow drift, I took 12 measurements around my street and took an average of my observations.  Currently, it appears there is 10.5" of snowfall on the ground for the suburbs of Newark, NJ.  



Now, with that said, there is already 10.5" on the ground and about 10 more hours of heavy snowfall with rates upwards of 1"-2" per hour.  This, combined with the observed location of the heaviest snow bands, it appears we should expect higher snow totals than the previously forecasted 15"-18".  The NWS also has increased their snowfall totals for the area to 24"-26".  I would have to agree with this forecast as the radar indicates the snow bands are set up over Essex, Bergen, and Passaic Counties.  It is very possible for another 10"-15" of snow to fall before this storm is all said and done Monday morning.

Blizzard 2010 UPDATE 3:50pm

This update is simply to adjust storm totals for the area... 
More accumulations were expected during the afternoon hours prior to the blizzard conditions developing.  That was why snowfall totals were initially increased to 20"-24".  Unfortunately, only a couple inches were accumulated up to this point across the region.  This in accordance with the location of the heavier snow bands will result in lower accumulations across the region.  This doesn't mean the storm is a bust by NO means.  We should expect 15"-18" of snow for NE NJ. Everything else previously discussed about this storm is on pace to occur.  We have already had wind gusts at 30 mph and that is expected to increase to 45-60 mph later in the evening.  

During a snowstorm like this one, you hear a lot of talk about banding.  These are the areas in which the heaviest snowfall occurs.  These areas are typically steady throughout a single event and become, for lack of a better term, ground zero for the highest snow totals.  These are not easy to forecast and therefore, snowfall totals are constantly in flux throughout a major snowstorm like this one.  That is why, the more we better understand where this snow band will set up, the better we can forecast the exact storm totals.

Blizzard 2010 UPDATE

Ok well that didn't take long...
Update 1:10:
      It looks as though the storm is taking a more westward track.. As a result, the heaviest snow bands should impact NE NJ as well.. In my previous post, I warned that the heaviest bands will be over central and western LI but could shift west. Well, it did. As a result, snow totals will be increased across the area.  It wouldn't be surprising to see almost 2 feet of snow across the NYC Metro! NE NJ should see anywhere between 20"-24" of snow by Monday morning.  Below is a snow fall forecast courtesy of New York City NWS.

And So it begins...

12:00pm.... Well, light snow has begun to move into the area and already there is a dusting of snow on the ground.  As I expected, blizzard conditions were posted yesterday afternoon and they continue through Mon morning.  The latest model runs indicate the possibility of 45-60 mph winds could occur throughout the NYC Metro making travel very dangerous, if not impossible.  The heaviest snow bands should develop over Nassau and Suffolk counties and, depending on the exact track of the Low, could enter as far east as NYC.  As a result, those snowfall totals could be as high as 18"-20".  For NE NJ, there will be a steady rate of heavy snow from late this afternoon through 3am, before tapering off by Mon morning.  Snowfall totals for the area will be anywhere from 8"- 14" by the time this storm has passed.

I will have further updates throughout the day so keep checking in.... Happy Blizzard '10 everybody

Today was born to us, a Christmas storm... UPDATE 1:40 pm

UPDATE 1:40pm:  OK, so after analyzing the 12Z model runs, it looks like every model is in consensus that this storm is going to be a monster.  I expect blizzard watches to be posted by tomorrow morning.  This is setting up to be a classic northeast snowstorm! I'm much more confident in my previously forecasted snow totals of 10"- 12" with locally higher amounts in stronger snow bands.


12:00pm: A week ago, the GFS model forecasted an incredible snowstorm for Christmas Eve into Christmas morning.  As meteorologists, we look at this with much skepticism and call it wish-casting.  As the days progressed, the GFS was holding firm.  The NYC Metro area was going to get slammed.  Then reality began to sink in as other models were able to pick up the storm.  However, on Tues and Wed, the rest of the models shifted the storm 100 miles east, making this storm nothing more than a few clouds and wind for our area.  This was the case until Thursday night, when the GFS once again shifted the storm 100 miles west.  The question arose, "Was this an initialization error or is the GFS picking up on something all other models aren't?" After the next model run a few more models were shifting west until we came to last night and this morning where all of the models are now predicting this storm to ride the coast.  So what does this mean for NE NJ?

Well, for starters, it means we will be getting a whole lot of snow and a whole lot of wind.  The Low pressure that will be disrupting our post-Christmas travel plans is currently dumping several inches of snow across the southeast.  Between now and Sunday afternoon, it will begin to push along the east coast.  As it does it will phase and strengthen, doing something we meteorologists like to call "bombing out." 

Light snow will begin moving in from the south Sunday morning.  By Sunday evening, the heavier snow bands will begin to move into our area along with increasing winds.  Wind overnight could gust as high as 35-40mph causing white out conditions while making driving nearly impossible.  The big question remains, how much snow will we have when all is said and done?

The NWS is currently forecasting 6"-8" for NE NJ with higher amounts further east.  This is a good estimate; however, I believe it's a bit conservative and cautious.  I'm calling for snowfall totals to be 10"-12" or greater for areas in NE NJ with higher snowfall totals further east.  This isn't a storm to be taken lightly.  We currently have Winter Weather Watches posted all across the Tri-State area and those watches will be upgraded to Warnings by 8pm. 

Only time will tell, but I'm rather confident that this will verify.  So get your shovels and sleds out, because the only bad thing about this storm is that it's happening over winter break and school's already out for the holidays.  Stay warm and make sure you dress in layers if you will be outdoors during the storm.

I'M BACK!!

Ok everyone, I'm sorry I haven't posted in a while but life got a little hectic. After a wild hurricane season, we are off to one of the coldest and stormiest winters in a while, especially along the west coast and Europe. There is the potential for an East Coast snowstorm Sunday-Monday; however, I am not all that confident in that scenario. I will have more on this storm and the wacky weather in the West Coast and Europe later in the day! For now, I just wanted to say I'm Back!
