messenger.....(you usually answer)

what do ratio's look like over the region guys? i.e GC/ 495/ SE Mass/CC

also sneaky warm layer's showing up anywhere? anything modeled....

I looked at the click sounding deal on twister for my area and it looked fine until 12z ish...after that it was a little toasty but way down low. The clown graphics which ironically have been very good this year have me on the line for a bit 1000/850mb temps. From my experience watching that line this year, the actual mix/change line is SE of it by a few clicks each time - 12/26 for instance. Logic tells me I'm still going to have issues here unless the track is over ACK and even then, it's a touch and go deal.

Ratios, I always assume 10 to 1 but that's because of where I live....will/scott/etc can better answer.

Happens to Kevin all the time without Ambien.

LOL, I actually hate the stuff, feel awful the next day.

I actually think GYX is a little gun shy after the boxing day storm. All of southern NH and Maine where 15-24 inches was forecast ended up with 6-12 at most, more common around 7 or so. Then on top of that, the White Mountains and western NH got 18-24 inches of snow, when they were supposed to get far less. That storm was a lot different than this one though.

Stuff is nuts, sleep like a log but wake up wearing lipstick, a coon skin hat and cheekless chaps.

It's amazing that it just shuts down all parts of the brain but the motor skills.

I think I'll just drink a Bushmills. If I'm interested in that other stuff, I can find that around here, too.

I wish there was a way to rig the internet so that when kev/kgay wake up in a few hours and say "here we go...game on" we can say "wtf you all

talking about...u guys dream like weenies...we're under a 570dm ridge and are expecting record highs tmrw. Get a grip"!

Well, the 18Z GFS greatly improved the precip in Maine and NH, I hope the trend continues. They should look at everything though, the Euro used to be god. I think more favor the north trend of precip right now.

18z GFS only brought the .75" line further north, They are expecting 12:1 ratios, So 6-12" is in line, We need the low to come further north into the GOM, 00z Nam made it as far as Portsmouth before it went ENE shutting the precip off from advancing further north and west.........

I am rather interested in what Mr Ekster would forecast were he on the job right now. (hint, hint)

Ratios near 10:1 unless in strong banding?

Well in areas where BL temps arent near 32F, I could see ratios higher than 10 to 1 as long as snow growth is good...and it looks like snow growth will be pretty good in most areas. It will be even better ratios in the heavy bands.

You want to get them up just text them that the Nam and GFS @00z went east 100 miles that should do it....

Why 12-1? Wow, it's 13F here right now, I know there is more to it though, but it looks like good snow growth.

Why 12-1?

A GENERAL 12 TO 1 RATIO FOR SNOW BASED ON QPF

FROM THE WETTER NAM...DRIER GFS...AND HPC. TWO FACTORS WORKING

AGAINST HIGHER RATIOS...WINDS CAUSING BREAKUP OF THE CRYSTALS AS

WELL AS AN INFLUX OF SLIGHTLY WARMER LLVL AIR LATE IN THE STORMS

PASSAGE ALONG THE COAST.

Just watched Matt Noyes, said he's not buying the models saying the R/S line makes it up to DUX/Marshfield, said it will most likely stay down by the Canal and immediate coastline.

That's because he just saw the NAM!

--

Guys up north I wouldn't give up on more QPF yet...NAM may still be holding too much back to the SW in lieu of you guys, let's see what the others show but it's probably looking good.

Yeah ratios arent as dependant on sfc temps as people think...it has a lot to do with snowflake type. Ive seen 15-1 ratios at 31-32F and ive seen 10-1 ratios at 10F. If im not mistaken BTV had 10-1 ratios in the valentines storm despite being around 10F.

NOOOOOO!!!!!!!!!!!

9:47 pm GYX update:

WARNINGS AND ADVISORIES APPEAR TO BE ON TRACK. 00Z NAM IS SLIGHTLY

FASTER AND SLIGHTLY FURTHER NORTH AND EAST WITH THE POSITION OF

THE SURFACE LOW TOMORROW. THEREFORE...WITH THE NORTHERN SHIFT AND BIAS

WITH THE MODEL(S) APPEARING TO HAVE STOPPED...WILL NOT EXTEND THE

WINTER STORM WARNINGS FURTHER NORTH AT THIS TIME...AND WILL ALLOW

THE MIDNIGHT SHIFT TO LOOK AT THE REMAINDER OF THE 00Z MODEL SUITE

TO REVIEW AREAS WHERE CURRENT ADVISORIES ARE IN EFFECT.
