Ed Lizard Posted January 20, 2013 Share Posted January 20, 2013 That stinks. Sounds similar to the deluge we had in late December. Since solutions of both GFS and Euro seem very variable between runs, I think you guys have to stay glass full optimistic. Link to comment Share on other sites More sharing options...
Ed Lizard Posted January 20, 2013 Share Posted January 20, 2013 Can't stay up for PPV AccuWx 6 hour EC maps, on the free PSU e-Wall version, the low moves in 24 hours from near Cincinnati to just East of Boston, with no obvious signs to this amateur hobbyist of a secondary. It is mostly snow in BOS per PPV text... GFS not super well supported by ensemble means Link to comment Share on other sites More sharing options...
PB GFI Posted January 20, 2013 Share Posted January 20, 2013 It's not a bowling ball scenario....I see no closed h5 low bowling its way east....it's called a re-developer Sighhhhhhhhhhhhhhhhhhh, Its a bowling ball in the sense that it comes under the PV ......................................

rcad1 Posted January 20, 2013 Share Posted January 20, 2013 The 12z models should be interesting. Especially since now the the 06z gfs has Come further North. Starting to womder if this is the beginning of a bad trend for NYC hopefully the12z euro Comes in South of the 0z!!!!!!!!! Link to comment Share on other sites More sharing options...
weathermedic Posted January 20, 2013 Share Posted January 20, 2013 Guys, don't write this event on or off just yet; this is what Upton said this morning about the potential event for Fri: MODELS ARE SIGNALING POTENTIAL FORA MORE SIGNIFICANT LOW PRESSURE SYSTEM TO END THE WEEK/START THEWEEKEND AS A RESULT. BUT BECAUSE THE ENERGY FOR THIS SYSTEM IS STILLIN THE BERING SEA AND NOT EXPECTED TO WORK INTO THE WEST COASTTILL MIDWEEK THERE IS AN ENORMOUS AMOUNT OF UNCERTAINTY ON DETAILSAT THIS TIME. THIS IS BORNE OUT BY THE STILL WIDE RANGE OF MEDIUMRANGE OPERATIONAL MODEL AND ENSEMBLE MEMBER SOLUTIONS Link to comment Share on other sites More sharing options...

WintersGrasp Posted January 20, 2013 Share Posted January 20, 2013 As it is modeled now, this is a mixing scenario for NYC. Primarily snow and all frozen but most likely 3" of snow followed by sleet Link to comment Share on other sites More sharing options...
PB GFI Posted January 20, 2013 Share Posted January 20, 2013 The trend north needs to stop. Have no room for error anymore HR 90 850`s are minus 18 . 24 hrs later it scours it all out ? Wait until this thing is in the plains Tues AM and sees all that low level cold air , its in the Bering Sea , plenty of time to sort . It doesnt mean it cant scour it , but it exits off NJ . 5 DAYS AWAY . way early to call for accum . wait until Tues AM Thats a lot of dense cold air to displace .

I'm almost positive that the models will trend colder, and I'm also fairly confident in AT LEAST a 3-6" snowfall for our area, with 50% chance of even 6"+ Link to comment Share on other sites More sharing options...

SnowGoose69 Posted January 20, 2013 Share Posted January 20, 2013 I generally do not like SW flow events for this area which involve some sort of ridge out west, those tend to trend north as the event gets closer...you usually want to see a shallow trof along the West Coast like 12/19/08 which keeps the wave somewhat suppressed and the flow progressive...the ridging out west can allow too much digging and amplification over the Ohio Valley and as a result the system goes north.

bluewave Posted January 20, 2013 Share Posted January 20, 2013 I generally do not like SW flow events for this area which involve some sort of ridge out west, those tend to trend north as the event gets closer...you usually want to see a shallow trof along the West Coast like 12/19/08 which keeps the wave somewhat suppressed and the flow progressive...the ridging out west can allow too much digging and amplification over the Ohio Valley and as a result the system goes north. I generally like less amplified solutions like 2-22-08 for the coastal sections not to change to a mix and then rain. But the marginal NAO will allow the PV inch east while the SE Ridge creeps up just enough to warm the coastal sections with too amplified a solution.

What does cold air by itself have to do with it? Is there anything to keep the cold air in place? Most of you are too young to remember but in 1994 it was -1 in the AM and 24 hours later in 55 with rain. This 22 degree cold is hardly cold.
