wisconsinwx Posted January 9, 2013 Share Posted January 9, 2013 Big difference between here and Chicago. 37F right now with still an inch or so of snow on the ground in most places, and a howling wind making it feel like 30. Didn't get to 40 in the suburbs I believe, though MKE did hit 42. Link to comment Share on other sites More sharing options...

cyclone77 Posted January 9, 2013 Share Posted January 9, 2013 45 today. Snow cover is pretty much gone. Just piles and mud left. Link to comment Share on other sites More sharing options...
SpartyOn Posted January 9, 2013 Share Posted January 9, 2013 By Sat the snow should be long gone here. Classic thaw. Now the wait to rebuild the snow pack. Link to comment Share on other sites More sharing options...
frostfern Posted January 9, 2013 Share Posted January 9, 2013 18z GFS. Two clippers track too far north for any decent LES, yet again.... Then another rainstorm at 384 hrs... . Northern Ontario has a ton of snow on the ground and they're just going to keep hogging it all the whole winter it appears. Link to comment Share on other sites More sharing options...

You can get good snow on any side of the low with a clipper..... Yes they do, and usually if you are South of a clipper track it tends to not yield for your area at least not synoptically.

cyclone77 Posted January 9, 2013 Share Posted January 9, 2013 Euro delivers over an inch of rain here tomorrow and tomorrow night. Sucks it's not snow but it's nice to have some much needed moisture. Link to comment Share on other sites More sharing options...

You can get good snow on any side of the low with a clipper..... I thought that was where we wanted clippers to go, as they would bring westerly and southwesterly winds off the lake, giving us some lake effect... Unless moisture is "lacking" again.

TugHillMatt Posted January 9, 2013 Share Posted January 9, 2013 Well, one positive of this winter is that I don't have to watch a snowpack melt over the next couple days in this thaw... Link to comment Share on other sites More sharing options...

They obviously have a warm sector, but its not as substantial as a sub tropical connected mid latitude cyclone. Link to comment Share on other sites More sharing options...

An impressive amount of moisture being pumped in from the gulf for January that's for sure. Link to comment Share on other sites More sharing options...

SpartyOn Posted January 10, 2013 Share Posted January 10, 2013 It was a glorious day. Was able to accomplish many outside tasks including a siding project on my mud room. The wind was annoying but the mid winter sun felt nice on the face. Snow cover is taking a major hit around here, wont be much left by Saturday which is fine because the snow pack looked dirty anyhow. So too "positive polly" it up in here, Im hopelessly awaiting another decent snow storm. Link to comment Share on other sites More sharing options...

Im unsure of measured gust speeds, a good estimate maybe a few 30-35s. My neighbors must have got a good laugh watching me chase rouge peices of siding that the wind picked up.

Brewers Posted January 10, 2013 Share Posted January 10, 2013 30° here, but low 20's being reported W/C WI. Surfacing ridging overhead is producing ideal conditions for radiational cooling tonight. However incoming high clouds from our approaching shortwave should prevent temps from dropping too much. Link to comment Share on other sites More sharing options...
Geos Posted January 10, 2013 Share Posted January 10, 2013 Made it to 45° today. Still clear here at 29°. Tomorrow will be cooler with a wind off the lake. Rain forecast to move in at about 3pm. Link to comment Share on other sites More sharing options...

Northern Ontario has a ton of snow on the ground and they're just going to keep hogging it all the whole winter it appears. The direction of the storm track over the entire period coming up is VERY clipper prone... I can spot several in the pipe-line. LES could really start to pile up.

LES could really start to pile up. As long as the flow is west/wnw all will be good and thus yeah the LES may start to really pile up in W.MI. I personally think the models are trying to push things a bit too quick.. Again lets hope the MJO not only does a loop in phase 6/7 but as well craps out ( or atleast hangs out there for a while ) at/near the 6/7 line..

Unless moisture is "lacking" again. Heavier LES can occur in the warm sector of a clipper provided the lapse rate is steep enough and the cloud layer extends all the way through the DGZ. If the DGZ is high and the inversion level is low don't expect much to happen ahead of the front. Link to comment Share on other sites More sharing options...
frostfern Posted January 10, 2013 Share Posted January 10, 2013 Pretty much. Only exception sometimes is in those areas downwind of the lake. Sometimes there is convective snow with an arctic front tied to a clipper. It depends on how potent the upper level portion of the wave is. There are different "types" of clippers. The ones shown on the GFS look more like WAA variety, i.e. not very steep lapse rate environment south of the low and thus not much precip in that sector.

Geos Posted January 10, 2013 Share Posted January 10, 2013 I remember some clippers that have had a band of moderate to heavy snow lining the cold front! Sometimes those events can put down a quick 2-3" of fluffy snow. EURO really loops the MJO around that 6-7 area. http://www.cpc.ncep.noaa.gov/products/precip/CWlink/MJO/CLIVAR/clivar_wh.shtml Link to comment Share on other sites More sharing options...

ukrocks Posted January 10, 2013 Share Posted January 10, 2013 Got well into the 50's this afternoon. It felt like a late February day, not a mid-January day. Tomorrow could get warm, depending on the timing of the warm front. We will see, if it can squeeze by here early afternoon, we may hit 60 three straight days, Link to comment Share on other sites More sharing options...

frostfern Posted January 10, 2013 Share Posted January 10, 2013 I remember some clippers that have had a band of moderate to heavy snow lining the cold front! Sometimes those events can put down a quick 2-3" of fluffy snow. There was a really good case of "warm" sector snowstorm in February 2002. A foot of snow fell in a period of 5 hours over parts of W MI with thundersnow along and ahead of the arctic front. I recall the totals were pretty significant even in WI before it scooped up the lake moisture. The thing was associated with extremely cold 500 mb temps caused by a small chunk of the polar vortex pinching off over the northern plains and then quickly scooting east. A quick 3-5" is a lot more typical for GRR with a stronger clipper / arctic front. Link to comment Share on other sites More sharing options...
