cyclone77 Posted October 16, 2011 Share Posted October 16, 2011 DVN raob sounding from 12z on the 19th from that event, 900mb-750mb layer a touch above freezing but im guessing shallow convection probably helped that. This storm had a last minute NW shift. We were forecast to be on the northwest edge of the main snow band. IIRC our original forecast was for 4-8", but we obviously blew that out of the water. Somewhere in central Missouri got close to 20" IIRC. Link to comment Share on other sites More sharing options...
cyclone77 Posted October 16, 2011 Share Posted October 16, 2011 12/6/94... Notes: -A significant ice event occured just south of the heavy snow. The ice caused significant damage and knocked out power to over 300,000 people. Man you're on a roll today lol. This happened to be the most impressive/damaging ice storm I've ever witnessed. I was in high school at the time. I remember being at school and being pissed off that freezing rain had started falling, as we were forecast to get 6-10+" of snow. We had a very brief period of large flakes mix in early on, but it was all freezing rain (at times heavy) the rest of the day and night. Lost power for a few days from that.

The thing that was impressive about the April 1982 event was how cold it was for that time of year. 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.

Thundersnow12 Posted October 17, 2011 Author Share Posted October 17, 2011 11/30-12/1/06 Yet another cutter....this was the first big snow event that I really got into and followed sine it started showing up in model land. I can still remember going down to U of I to watch my HS football team play for the state championship and thinking about this storm. Also, Rick Dimaio, the old meteorologist on FOX the night of this thing held up a sign that said "10-16" as he said thats all you need to know folks, still is my favorite weather broadcast to date. It was a sleet fest at my house in Batavia until it switched up to +SN in the early morning hours and picked up around 7-8". Thanks to the last minute northwest shift places like LaSalle/Peru up through RFD-DKB and cyclone were the big snow winners. Day 1 - Forecast valid from 1800 UTC 30 November to 1800 UTC 01 December 2006 WV loops depict organizing area of moisture over N TX, W OK, and S KS this morning ahead of positively tilted mid-level trof. Powerful vort max near base of trof over W TX panhandle at 12Z, with significant 700-300 mb Q convergence centered on PPA (downstream, over N TX panhandle) on western edge of burgeoning moisture area. Morning radar summaries depict expanding area of precipitation over W OK, with banding structures already apparent west of the nascent low near Texarkana. 12Z/30 GFS solutions dominate this outlook, as the best run-to-run continuity has emerged over the last 12-18 hrs with that platform. Some support also comes from the 12Z/30 NAM, 00Z/30 runs from the in-house WRF and MASS-KF and MASS-Grell models, and a peek at the 15Z/30 RUC output. Largely a continuation of yesterday's outlook for this period. Region of best ingredients for TSSN is on the move, appearing near the intersection of the trowal axis, and the the axis of the emerging dry slot a la Nicosia and Grumm. 700- to 600-mb frontogenesis in presence of deep moisture and elevated CAPE values hover near this area, in a storm-relative sense. 700-500 lapse rates have been less than ideal, simply because frontal inversion now exists between those levels in many instances. However, model solutions do suggest substantial elevated CAPE values above the frontal zone, even though many of those parcels originate from 600-625 mb. Example from the 12Z/30 GFS 18Z solutions include 187 J/kg of CAPE at CQB for a parcel originating at 600 mb; this pattern diminishes at CQB, but persists at 00Z/01. These ingredients for elevated instability, with ample moisture and significant forcing progress across NE OK and into SW MO by 06Z/01, into the C75 region of IL by 12Z/01, and into the LP of MI by noon tomorrow. Convective snow anticipated. stuff I pulled out of the Eastern thread.. 12z NAM run on the 30th with snow amounts for IL, heaviest amounts ended up being northwest of these area due to the late northwest shift and more WAA. O'Hare 16.3 Peoria 12.8 Rockford 11.7 Midway 11.6 Pontiac 11.4 Joliet 8.1 Bloomington 7.2 Kankakee 5.0 "STL mentions local amounts of 18+ possible in the afternoon update." on the 30th..less than 18 hours away from onset... 12z Friday positions from the Plymouth site: UK has a 996 low over Lafayette Euro 993 over Danville GFS 995 Champaign, maybe a tad south of there NAM 2 lows? 983 over Effingham and 994 east of Indy NGM 994 over Bloomington IN from Gilbert's forecast.. "6 AM-2 PM...heavy snow. Best bet is 6 AM through noon. Snow will fall at the rate of 4"/hour at the height of the storm. North winds at 20-40 MPH will gust to 45 MPH. Visibilities near zero with blizzard or near blizzard conditions. Snow tapers off to light snow after noon. 2 PM-6 PM...snow ends quickly. 45 MPH northwest winds continue under cloudy skies. Ground blizzard or near blizzard conditions likely due to blowing and drifting of the snow."

cyclone77 Posted October 18, 2011 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. Link to comment Share on other sites More sharing options...
