Mid week storm talk continued

i hear ya. im not saying they are wrong. i already stated i'd rather not touch a freezing rain forecast unless i was forced to. in this instance with this low track i still tend to think that there is a greater shot of ice being 'less than' rather 'greater than' forecast. wasnt the 12z nam colder than it had been though? if so i'd be nervous it was one of it's burps in the short range. it is not very consistent lately.

It looks like the 6Z NAM was the coldest run.

Paraphrasing the NWS link that was provided in that thread, it said to take a "very small twig" and measure the full width of ice. I assume you could do this with a larger branch and than subtract the diameter of the branch.

really? i thought it was only one side...

Yeah I thought it was take the top and bottom and then average or something like that. No clue.

Meanwhile - I think NinjaWarrior should be 5ppd until he/she posts their location. And it should be mandatory to become a member. :thumbsup:

I think the 06Z nam was also pretty cold when I looked at the soundings. The 18Z nam looks very much like yesterday's 12Z run and really shows an unstable layer. Note how the temperature line above the inversion tilts back to the left faster than the curved dashed lines near it. That's a more impressive unstable layer than during our thundersnow event. The surface temps are a little above freezing all the way to HGR on the 18Z nam though I suspect back there the temps might still be right at freezing. Still heavy rain falling at 32 degrees rarely produces freezing rain as the droplets will not be supercooled because the cold layer probably won't be deep enough.

it is... maybe just confused with ellinwood's phrasing.

The best way to measure ice accumulation is to break off a very small branch/twig from a tree. Use a ruler to measure the thickness of ice in tenths of an inch. There may be one side of the branch or twig with a greater thickness of ice than the other side. In this instance, please report the average thickness of ice buildup.

Heh you guys are right. I read it wrong. Sorry, I'm exhausted right now :arrowhead:

I'm an addict, lurking in the central threads, taking hits off of their excitement and end-of-days advisories. Lucky bastards.

A friend of mine had to travel to O'Fallon, IL for work this week. When he landed this morning, I sent him the forecast from St. Louis NWS office for there. 0.75-1.00" ice tonight, 12-18" snow with 40 mph winds tomorrow and tomorrow night. He didn't seem too pleased.:P

I'll be curious to see what the DPs do before the precip gets here tomorrow evening. Since the temps probably wont get far above if at all past 32, I know we'll be in trouble out here in the western burbs with a DP of about 27 or lower. If it's above that, I think we'll be OK in general.

18Z NAM IAD forecast (at 18Z Tues): 0.2C/-0.9C

18Z GFS IAD forecast (at 18Z Tues): 1.9C/1.8C

Can someone direct me to a thread where I can cry. Watching TWC,browsing accuweather and hearing all the hype about this storm has depressed me.Id kill to be in the midwest. Im on the verge of a maryland winter cancel.Looks like our next few threats currently shown wont materialize.Next thing you know it will be mid February with nothing to show for it.Thats why I always had reservations about hinging the whole winter on February like most on here always seem to do.

I might be one of the few, but I'm grateful for what I get snow wise. The storm last week was a pleasant surprise in a rather hit (and mostly) miss winter. I'm more concerned about travel the next few days, me getting to work and getting my wife to the doctor's for an antepartum checkup this week.

I suspect you are at your seasonal average or close as I am.

Can someone tell the people in the NY thread an "ice storm" in the New York and its immediate burbs, probably is not going to be like they think it is. I'm sorry, I have a heard time believing Manhattan is going to be encased in a half-inch of ice. Maybe it will happen, but seems doubtful consider they are surrounded by three bodies of water, and sit atop a mega heat island.
