Thundersnow12 Posted October 18, 2011 Author Share Posted October 18, 2011 That last minute NW bump on the 12/1/06 storm was awesome for this area. It was a nail biter all the way up until when the snow began. The snow actually backed in from the southeast agonizingly slow as it fought very dry/cold air. We went from not a flake to be seen to heavy snow a very short period of time. The winds also kicked up dramatically right as the snow arrived. It was odd to see the winds kick up at the beginning of the snow like that. Often times the stronger winds extend further west outside of the snow band. We ended up with 10-11" here. even though that kind of screwed me here, still one of my favorite events. I think Skilling mentioned TSSN possible like 3 days out or something like that.

Chicago Storm Posted October 18, 2011 Share Posted October 18, 2011 11/30-12/1/06 This event occured before I started keeping records, but the COOP site came in with 6.3" This was the only decent snow event during the month of December, with only 0.3" being recorded the rest of the month.

Chicago Storm Posted October 18, 2011 Share Posted October 18, 2011 Insane blizzard. Up until the GHD storm I hadn't seen anything like that since. We had winds pushing 50mph with the GHD storm, but I suspect the winds pushed close to 60mph with the '87 storm. There was also rounds of frequent lightning with that storm. Top gusts across the area... ORD: 64 RFD: 61 PIA: 59 MDW: 58 MSN: 58 MKE: 53 MLI: 46 Link to comment Share on other sites More sharing options...

Thundersnow12 Posted October 18, 2011 Author Share Posted October 18, 2011 probably going to start putting some mesoanalysis loops together of the GHD blizzard over the next few days. Link to comment Share on other sites More sharing options...
Thundersnow12 Posted October 19, 2011 Author Share Posted October 19, 2011 GHD Blizzard...probably my two favorite loops I could watch with this event. The phasing and then the tightening of the baroclinic zone and frontogenesis going crazy is so cool to me. Also, the 850mb loop is 6hr ahead of the PVA loop Link to comment Share on other sites More sharing options...

Thundersnow12 Posted November 5, 2011 Author Share Posted November 5, 2011 something i just did quickly looking at that Dec 1987 snowstorm for around here...what a beast, the baroclinic zone in place is nuts. Will probably do this map for the 12 hours after this. Link to comment Share on other sites More sharing options...
cyclone77 Posted November 5, 2011 Share Posted November 5, 2011 wish I was alive for that one lol thats a beast of a system. I'll never forget that one. I was only 10 but I still remember waking up around 3-4am and looking out at what looked like a white hurricane. I remember two plows coming from opposite directions on our street stopped in the road to talk to each other about two houses down. I distinctly remember the wind kicking up so hard that even with their strobe lights they were completely obscured in white. It was like a severe thunderstorm with snow that lasted for hours. It was pretty much what Alek encountered with the GHD storm. Link to comment Share on other sites More sharing options...
cyclone77 Posted November 5, 2011 Share Posted November 5, 2011 There's a great case study writeup regarding the '87 blizzard that goes into great detail about how gravity waves played a large role in the extreme wind gusts associated with this storm.

That storm puts the GHD storm to shame lol besides for amounts Yeah that was the one downside about the storm. Relatively speaking it was a quick mover. IIRC (at least in the QC) the heavy snow didn't kick in until after midnight and only lasted till about sunrise before tapering to lighter snow. Still picked up about a foot.

Ya from the sfc all the way up, its very impressive. Can't name another storm that got as deep as it did at 850mb. Link to comment Share on other sites More sharing options...
cyclone77 Posted November 5, 2011 Share Posted November 5, 2011 This is the most impressive graphic to me in the case study posted above. Look at how quickly the surface low bombed as it moved north through Illinois. Between midnight and 6am the surface low's pressure dropped from 992mb to 979mb.

Between midnight and 6am the surface low's pressure dropped from 992mb to 979mb. almost looks like an occlusion track of a meso with a supercell but on the synoptic scale. I've never seen something like that before, then turned northeast again and continued to deepen. Link to comment Share on other sites More sharing options...
