Yea seems to me that at least across the interior and away from the coast it could be cold enough to support snow. We will see how it progresses.

850 s are below 0 all the way to the coast . These set ups don't always have to JP the coast and this is a big board . So when you make a general statement like that , its just a bad post .

There is a huge PNA spike , the Euro deepens thiis up the EC.

Don't worry about temps yet .

The signal on the EPS is only 4.5 days away .

AS MENTIONED IN THE AFD YESTERDAY, WE ARE WATCHING THE POTENTIAL
FOR ANOTHER COASTAL LOW LATE IN THE WEEK. MODELS ARE GENERALLY
SHOWING A STORM SYSTEM ORGANIZING SOMEWHERE OVER THE GULF COAST
OR JUST OFF THE SOUTHEAST COAST. THERE IS A HIGH MODEL SPREAD
THOUGH WITH REGARDS TO THE TRACK AND STRENGTH OF THE LOW.
YESTERDAY IT WAS THE 12Z OPERATIONAL GEM THAT ADVERTISED THE LOW
TRACKING UP THE COAST WHILE THE OTHER OPERATIONAL GUIDANCE WAS
OUT TO SEA. TODAY, IT`S THE 12Z OPERATIONAL ECMWF THAT HAS BRINGS
IT UP THE COAST WHILE MOST OTHER GUIDANCE IS OFFSHORE WITH THIS
SYSTEM. THERE IS SOME SUPPORT FOR BOTH SOLUTION FROM THE GEFS AND
ECMWF ENSEMBLE MEMBERS BUT AGAIN THERE IS A LARGE SPREAD. UNLIKE
WITH YESTERDAY`S EVENT, THERE DOESN`T APPEAR TO BE AN AREA OF HIGH
PRESSURE ANCHORED TO OUR NORTH TO LOCK IN THE COLD AIR.

The timing of the change, coming in climatologically coldest part of year was extremely key. This happens one month from now & its a wholly different ball of wax , one with a lot of tears for us!

 

Correct N in Jan with a trough in the SE , SSTJ + PNA  ridging on the W shore of HB was just asking for trouble . It only had to be cold enough and that look at 500 that was seen at some distance materialized .

 

There is a threat this weekend and then the warm up will be another transient one by D 11- 12 you will start to see the above look come back in the means .

Looking more and more like muted mini-torches.  No real Arctic blasts, either.  Lots of 35-40 days which is just fine for me as a pack retention guy.

There is just too much trough in the SE as a result of where that GOA low is . It wants to stay around 150 so any ridging just flies through the flow has and no staying power as the ridge builds back on the WC towards  HB .

 

N at the B/L ( frigid sux )  is perfect as long as we look like this at 500 - " just cold enough " with a STJ .

 

Amazing  there is AN snow for the I95 NYC and S . We are playing with house $ .

THURSDAY NIGHT THROUGH FRIDAY...A LOW PRESSURE SYSTEM DEVELOPS
OFF THE COAST OF THE SOUTHEASTERN UNITED STATES AND THEN TRACKS TO
THE NORTHEAST. THERE IS CONSIDERABLE DIFFERENCE IN THE MODEL
GUIDANCE WITH THE GFS TAKING THE STORM OUT TO SEA WITH LITTLE
IMPACTS TO OUR AREA WHILE THE ECMWF KEEPS IT CLOSER TO THE COAST,
BRINGING ANOTHER POTENTIAL WINTER STORM TO THE REGION. ANOTHER
DIFFERENCE IN THE MODELS IS A NORTHERN LOW PRESSURE CROSSING THE
GREAT LAKES. THE STRENGTH OF THIS STORM MAY BE IMPACTING JUST HOW
CLOSE TO THE COAST THE SOUTHERN STORM MAY REMAIN. WE WILL FOLLOW
WPC GUIDANCE AND BLEND WITH CONTINUITY DUE TO THE UNCERTAINTY OF
THIS SYSTEM AND THEN CONTINUE TO MONITOR THE STORM OVER THE COMING
DAYS.

the ao/nao is forecast to rise over +3 and then fall back to negative again...This makes me think we will see a major thaw probably brief and cold will follow that...The timing looks like just after Feb. 1st...February could start out like 1983 with near record warmth...to early to say February 2016 will yield a storm like 1983...we already saw that the other day...two in one year?...

2M temps over the next 10 days compliments of your snow cover .

 

You spike D 9 - 11 as a system cuts to the lakes and then the trough comes back D 12 -15 

The EPS look at 500 has the GEFS/GEPS agreeing with the look . 

 

D 1- 8 look to be a few AN . 

 

The warm up looks transient .
