Thunder Road Posted December 11, 2012 Share Posted December 11, 2012 Flakes starting to fly here. Down to 28°. Heard Valparaiso picked up an inch at least tonight. Campus is east of downtown and we had more like a half inch. Plenty of grass showing and sidewalks only wet, although they're slippery now. Maybe just north of downtown though? There's a several mile expanse of residential areas north of "center city". Link to comment Share on other sites More sharing options...
PatrickSumner Posted December 11, 2012 Share Posted December 11, 2012 We had light snow on and off most of the night here in Marion. Quarter to half inch has accumulated... Link to comment Share on other sites More sharing options...
Indystorm Posted December 11, 2012 Share Posted December 11, 2012 Grassy surfaces are covered white this Tues. morning here in Michiana. Roads are wet to icy in spots. Lots of accidents in the region for the first snow as usual. Bypass 20 closed from St. Rd 19 in Elkhart to Elm road in Mishawaka due to 20 vehicles involved in three separate accidents.

Powerball Posted December 11, 2012 Share Posted December 11, 2012 Well I think we can all just be grateful that we finally have several storm and snow threats to track and discuss now within the 5-10 day range. This same time last year the forum was completely dead. Link to comment Share on other sites More sharing options...

A-L-E-K Posted December 11, 2012 Share Posted December 11, 2012 amazing that we're going to see this kind of WAA over the plains in mid-december but still won't manage to see any kind of decent baroclinic zone thanks to a northern stream dislodged way into Canada. It's hard to buy into the step down theory of storm tracks when storm after storm fails to tap into any real cold air. Link to comment Share on other sites More sharing options...
daddylonglegs Posted December 11, 2012 Share Posted December 11, 2012 GFS shows temps only making it into the low 30Fs here...plenty cold enough for a deep, wet, heavy snow... There is the possibility of another huge December snow total if things go right. Link to comment Share on other sites More sharing options...

Chicago WX Posted December 11, 2012 Share Posted December 11, 2012 12 years ago today. Some snowfall totals from this storm: 13.6" at MKE, 9.5" at ORD, 8.3" at RFD, 13.5" at GSH, 12.0" at SBN, 14.0" at FNT, 6.1" at DTW, 15.1" at GRR, 14.5" at LAN, 13.7" at MKG. Blizzard Warnings were issued for Chicago and other places. And then this one followed two days later. This storm dropped 12"+ amounts in MO, with a wide swath of 6"+ amounts elsewhere. With the 9.5" I got with first storm and 6.0" with the second (both in Kankakee), it was pretty awesome. The rest of that month was cold/snowy history of course. Maybe my favorite winter month ever.

kab2791 Posted December 11, 2012 Share Posted December 11, 2012 A very nice storm indeed. I recall a Blizzard Warning for counties north of Detroit. There was a tight gradient across Metro Detroit. I remember receiving 10-12" just north of Detroit with whiteout conditions at times. There was some sleet mixed in at one point. The next storm dropped 4-6" here if I remember correctly.

hm8 Posted December 11, 2012 Share Posted December 11, 2012 Today in Southeast Michigan Weather History... On December 11, 2000, a powerful storm system moved east just south of Michigan, dumping heavy snow across all of the area, with some freezing rain and sleet near the Ohio border. Near blizzard conditions with up to 58 mph wind gusts were found across all of the area, with an outright blizzard in the Thumb. Many schools were closed for two to four days after the storm. Mail delivery the next day was spotty at best, and many businesses and government offices were closed. Specific snowfall amounts and impacts of the storm, by county... Bay: 8 to 10" in Bay City. Genesee: 12-14" fell, along with 4 foot drifts. Flint Bishop International Airport closed in the afternoon of the 11th, and ended up with 14", the third largest snowfall on record. Up to 200 cars were stranded on Interstate 75 just south of Flint during the storm. In Burton, the roof of a window manufacturing company collapsed. Huron: 16.2" in Port Hope. Lapeer: 12-16" near Lapeer (city), with 3 foot drifts. Interstate 69 was closed from Davison to Imlay City. Lenawee: 5.7" in Adrian with some freezing rain. Livingston: 10-15" with 3 to 5 foot drifts. Macomb: 12" across the county. Midland: 7 to 11" in Midland (city). Monroe: 8.5" just southeast of Milan; up to half an inch of freezing rain in Monroe with several trees downed due to ice and wind, and power outages. Oakland: 12" across the county. St Clair: 12.3" near Avoca; 14.7" in Ruby; 17.5" in Yale, 14" in Capac. In Port Huron, 12-20", closing the Blue Water Bridge to Canada.

Sanilac: 13" in Brown City. Shiawassee: 15.5" in Morrice. Tuscola: 10-14" in Vassar. In Caro, 16.3" of snow fell with 4 foot drifts. An 18 car pile-up on the north side of town required snowmobiles to rescue stranded motorists. Washtenaw: 8-12" in Ann Arbor; closing Eastern Michigan University for only the second time ever. Wayne: 6-12" across the county; three-eighths inches of freezing rain in Rockwood; At Detroit Metropolitan Airport, 6.1" fell, with 197 departures and 165 arrivals were cancelled.

weatherbo Posted December 11, 2012 Share Posted December 11, 2012 Was 19 here last night. easily the coldest of the season with the help of some snowcover and partial clearing. I was in the interior a week or so ago and in remote area with clear skies, my truck said 12. Good and bad what being so close to the lake will do for temps. Lake across the road is finally froze over. I'm tempted to go bust thru it with my yak, but would prolly be shot on site by the frothing at the mouth ice fisherman.

SpartyOn Posted December 11, 2012 Share Posted December 11, 2012 Got some nice TSSN out of that 2000 system. I worked at a local greenhouse that year and we had the lights off at one point to see the lightning flashes. The sky went blue and purple with a few flashes. Just an amazing storm!!Greatest Dec ever! Link to comment Share on other sites More sharing options...
cyclone77 Posted December 11, 2012 Share Posted December 11, 2012 Cyclone- What do you average a year in snowfall? About 33". We've had several 45"+ and many <20" seasons over the past 10-15 seasons. Got down to 16 this morning. Should pop above freezing this afternoon. Link to comment Share on other sites More sharing options...

beavis1729 Posted December 11, 2012 Share Posted December 11, 2012 Yep Alek...can't argue with that. All 28 years prior to and including the 1986-87 season had at least 9 days < 24F by Dec. 15. But that has only been accomplished in 14 of the 25 years since. That's an amazing difference. Link to comment Share on other sites More sharing options...
Chicago WX Posted December 11, 2012 Share Posted December 11, 2012 Winters are warmer no doubt about it, but dismissing UHI at ORD is kinda dumb. Alas, the 60's and 70's into the early 80's had some of coldest winters on record for Chicago (and the country) as well. There's certainly been a reversal since, overall.

Trent Posted December 11, 2012 Share Posted December 11, 2012 Urban Heat Island always makes me cringe. Most major American cities were much more urban decades ago. The proper terminology should be Suburban Heat Island as dense urban cities shrink and suburban sprawl development takes hold far from the urban core. I wouldn't be surprised if some urban rust belt neighborhoods have cooled a bit with the decline of factories and numerous buildings being razed with weed lots as replacements.

Alas, the 60's and 70's into the early 80's had some of coldest winters on record for Chicago (and the country) as well. There's certainly been a reversal since, overall. I'd say it's some combination of both factors. I'm not sure how much more built up the area around ORD is now (wasn't it already pretty built up in the 80s and prior?) so my first thought would be to put more emphasis on warmer winters in general.

I wouldn't be surprised if some urban rust belt neighborhoods have cooled a bit with the decline of factories and numerous buildings being razed with weed lots as replacements. True. In general, when I say "heat island", I mean the idea of human-impacted (urban and/or suburban) areas being warmer than rural areas. I agree with Hoosier that it's a combination of both. If you look at low temps each day across the state of IL during a 365-day period, you'll often find that the Chicago lakefront has the warmest low temp in the entire state. Many days, the lakefront will be 5-10 degrees warmer than ORD, and 10-15 degrees warmer than Rockford. That's the power of UHI. Just to be clear, this wasn't meant to be an AGW conversation. The changes in early-winter low temps by decade at ORD is an interesting (and rather shocking) statistic, whatever the reason. I've lived in the Chicago suburbs for 30 years, and it makes Decembers feel warmer than they used to be...so it seemed relevant to post in the December general discussion thread. When we had the very cold years in the early 1980s, it was pretty much all farmland once you traveled west of IMBY (Carol Stream). Now, if you take a 15-mile drive west of here, the area is all built up continuously. These changes are significant over a short amount of "geologic" time (30 years).
