JSTWX Posted February 1, 2011 Share Posted February 1, 2011 question how do you measure ice? do you just chip away and measure the height? there's no approved method to do so. Basically measure the thickness on a flat surface or from the edge of a tree branch. Kinda tough... Link to comment Share on other sites More sharing options...
hckyplayer8 Posted February 1, 2011 Share Posted February 1, 2011 question how do you measure ice? do you just chip away and measure the height? You have a picnic table? Tape/staple small ruler to the side of it. Link to comment Share on other sites More sharing options...
MAG5035 Posted February 1, 2011 Share Posted February 1, 2011 Just got out of a chat room with ctp.... reasoning is too much confusion to change the warnings at this point.... everyone knows it's going to be nasty with the current headlines. Yea it's probably complicated enough dealing with the thermal profiles in the region and hammering down where the worst ice is gonna fall and etc. Learned from my dad that coming over Brush Mountain into Bellwood (mountain to Altoona's east) it was 28 up top and 32 down here in the valley.. which is what I have on the basic thermometer here at home. Does lend support to the 925 subzero layer remaining anchored in place as per the NAM at least locally. The NAM initialized around -2 here and about -4 or so at UNV with the 0 line coming down near or just west of JST. While the 850 0 line remains near the NY border, the +2 line buckles south to near the MD border at hour 12, leaving 0-2ºC 850 temps in the Altoona-State College corridor with 925s at -4 at both cities. Hour 15 modifies at 850 a couple degrees but 925 still about the same. The 925 level never really even sniffs 0 for pretty much all of the precip event. So with a marginal cold layer from at least 925 to the ground it probably allows some sleet to mix in occasionally from say route 22 or so north. Any little bit of sleet taking up QPF would help, cuz that central area between AOO and UNV looks to be ground zero for the ice accretion in the local area.

hckyplayer8 Posted February 1, 2011 Share Posted February 1, 2011 Just no give in the GFS. I'm guessing with nearly everything against it, the NAM is just too cold. Link to comment Share on other sites More sharing options...
NortheastPAWx Posted February 1, 2011 Author Share Posted February 1, 2011 Should I expect more IP, more ZR, or a mix of both? Link to comment Share on other sites More sharing options...

sauss06 Posted February 1, 2011 Share Posted February 1, 2011 Just no give in the GFS. I'm guessing with nearly everything against it, the NAM is just too cold. and the gfs is rain, not FRZN Link to comment Share on other sites More sharing options...
Alleghenies-16693 Posted February 1, 2011 Share Posted February 1, 2011 I think I live where CAD was invented, at the junctions of Locke, Canoe and Short Mountain - separated by the Frankstown Branch, three miles north of Williamsburg. We have 3/8's going into this next round, DP and temp 31 - going down. Link to comment Share on other sites More sharing options...
Voyager Posted February 1, 2011 Share Posted February 1, 2011 more ZR imo.. He's nearly 1,000 ft higher than me. I'm about 825 or so. What do you think here? My guess is more zr than ip, but by what ratio? Link to comment Share on other sites More sharing options...

I have a feeling the nam is going to be a little too warm around here.... Im still in the mid 30s, with a dp in the mid 30s. Link to comment Share on other sites More sharing options...

My guess is more zr than ip, but by what ratio? he's probably more IP to start..maybe an hour or two of IP then frz....you look like a ton of frz and little IP imo...like 90%-10% Link to comment Share on other sites More sharing options...
PottercountyWXobserver Posted February 1, 2011 Share Posted February 1, 2011 I was getting like a freezing mist/drizzle up here not to long ago, hopefully that was just a dud and its snow when the heavier precip rolls in. Temperatures have really cooled off now down to 23.1°F with a Dew Point of 19°F. Winds are light to breezy out of the NE-ENE Link to comment Share on other sites More sharing options...
EasternUSWX Posted February 1, 2011 Share Posted February 1, 2011 fwiw the RUC also comes in colder...places in md don't get above 32 til precip is gone It's too warm to start with has us like at 33-34 right now. Link to comment Share on other sites More sharing options...

EasternUSWX Posted February 1, 2011 Share Posted February 1, 2011 Been sitting at 32 for over an hour now almost 2 hrs. When is it going to start falling is the question, or will it not fall. We shall see. Link to comment Share on other sites More sharing options...
2001kx Posted February 1, 2011 Share Posted February 1, 2011 been watching the chicago cam (wrigley field) i keep seeing something falling from the stadium but dont know what it is. some one walking by stopped and pick some of it up and kept it...whatever it was. anyone else see that? http://www.cubworld.com/category/a_cubworld_cam/ Link to comment Share on other sites More sharing options...

We shall see. has you're dp been falling...i've held steady at 30 but my DP is all the down at 22 so when the precip arrives i'll be knocked down a few degrees.

DP is steady at 28. I just went for a little walk. Funny thing is even though it's 32 and it was daylight none of the ice on the trees melted and it's still hard as a brick.

MAG5035 Posted February 1, 2011 Share Posted February 1, 2011 some intermittent freezing rain starting up here. Ice is still on the pines from this morning so never really got too warm. Temp is 31.9ºF on the Lacrosse wireless thermometer, gonna take the handheld out to get a followup temp and also a dewpoint. Link to comment Share on other sites More sharing options...
dcfox1 Posted February 1, 2011 Share Posted February 1, 2011 Temps here went from 25 most of the morning to 30 this afternoon, now dropped to 29. My Wx station is unusually right on with Millersville Univ obs. I moved my vehicle to the bottom of the hill and it has already started to refreeze at the bottom.

PottercountyWXobserver Posted February 1, 2011 Share Posted February 1, 2011 I feel bad for St. Louis they got totally screwed. They saw a little sleet then got the dry slot from hell, they aren't even going to be close to their 8-12" predicted! Temperatures are dropping like a rock here, I'm down to 21.8°F with the Dew Point steady now at 19°F, so my temperatures might settle down and hold steady soon.

EasternUSWX Posted February 1, 2011 Share Posted February 1, 2011 It's time to break out 2 thermometers. My one is at about 20 feet above the ground. I am going to put one at ground level as well. Link to comment Share on other sites More sharing options...
