Do you know any mets at TWC? They certainly knew there was less than a 1 percent chance of parts of the area receiving 3+ feet.

I do know a few mets there....but I'll admit TWC is a bit of a different animal than a local weather forecaster. I could totally see corporate there putting up more extreme graphics.

 

But pretty much every TV met I know has almost total autonomy on their own forecast graphics. Maybe there are some bad stations that force them to put bad graphics out, but I personally don't know any of them.

12-18" may be to low after this 18z Nam run..............:lol:

I have been thinking the snow amounts have just been too high up here.  NAM is giving me almost 2" again.  Even cutting those down by 1/3 but figuring a 1 to 15 ratio gives me a friggin lot of snow.

This is what I figured.

Thank you.

Dude, they need to get a Kev on there...he'd make them billions.

URGENT - WINTER WEATHER MESSAGE
National Weather Service Gray ME
330 PM EST Fri Jan 18 2019

...SIGNIFICANT WINTER STORM EXPECTED THIS WEEKEND...

A significant storm will move northeast on Saturday night,
spreading snow across the region. By Sunday, this system will
track along the southern New England coastline and through the
Gulf of Maine. This will result in heavy snow across the region
with widespread areas with double digit snowfall. Along the
coastline, a brief period of sleet may fall during the day Sunday.
Needless to say, driving conditions will be treacherous starting
Saturday night and especially Sunday when snowfall rates will
increase.

...WINTER STORM WARNING IN EFFECT FROM 7 PM SATURDAY TO 1 AM EST
MONDAY...

* WHAT...Heavy snow expected. Total snow accumulations of 14 to
18 inches expected.

* WHERE...Portions of central, northern and southern New
Hampshire and south central, southwest and western Maine.

* WHEN...From 7 PM Saturday to 1 AM EST Monday.

* ADDITIONAL DETAILS...Travel could be very difficult to
impossible. Patchy blowing snow could significantly reduce
visibility. The cold wind chills as low as 20 below zero could
cause frostbite on exposed skin in as little as 30 minutes.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Winter Storm Warning for snow means severe winter weather
conditions will make travel very hazardous or impossible. If you
must travel, keep an extra flashlight, food and water in your
vehicle in case of an emergency.

It will still fall in that range, GYX above agrees with it.

I would be apt to say these numbers are inflated due to inherit issues within the modeling dynamics.  For one, the icing is (from my understanding) interpolated over time period and does not capture what happens during intermediate time steps.  

Not to mention, the upper air temperatures aloft have been in question as to how much warm air will be overrunning.  Because the thermal soundings are in question, the ice accumulation rate forecasts will be questionable at best.  I would expect these numbers to fall as modeling time intervals become more refined.  

For sure.  Model is just pointing out where it is .  I think it ends up N of there those as I can't by any appreciable icing at the coast occurring.

18Z NAM is bringing more sleet over Northern MA, which is interesting.  I'd be more apt to say with this profile that it would likely be switching back and forth.  There will be some fine details needed to be worked out before I start making definitive yes all snow or mixing in my neck of the woods (north of Fitchburg, MA).

Yeah I agree.  Any mid level fronto bands will Punch better snow growth too.  I could see a wide swath of 12-18".  13-15:1 ratios on 1" QPF.   But I bet any 700-850mb frontogenesis in NNE gets up to 20:1 ratios.

Maybe during the snowburst it's 20:1, but less likely for the whole event.  Since moving to Maine (46 years ago this coming Wednesday), I've measured exactly one storm of 10"+ that cracked the 20 mark, a low-wind featherbomb in Dec. 1981 (thus Ft. Kent) that produced 15.5" from just 0.68" LE, ratio 22.8.  Next highest was 18.3 from a similar storm when I lived in Gardiner, 13.9" from 0.76" LE in early Feb. 1993.  (Lesser storms are different.  I've twice gotten 4.5" of freaky flakes from 0.10" LE, once in BGR and once in Gardiner.)

Like the little BN hook on that 12/1-forward temp map, as it reaches my place where I'm -2 compared to my 21-year average.
