Arctic Air ExpandsDecember 6th, 2013 at 3:00 am by Bill Steffen under Bill's Blog, Weather
First check out the huge storm surge from the 60 mph winds from a deep low pressure system pushing water towards the shoreline of Germany and Denmark. There has been a tremendous band of lake-effect snow going across Lake Superior. It crossed Houghton County, where they had 9″ of new snow and very strong winds that were putting large drifts across roads. Gusts included 63 mph at Keweenaw Pt., 62 mph at Goetzville, 54 mph on the beach at Charlevoix and 45 mph on Mackinac Is. The Superior snow band was coming onshore north of Sault. Ste. Marie were very heavy snow was falling on the road to Wawa. An ice storm was downing tree limbs and power line from extreme N Texas across SE Oklahoma, NW Arkansas and all the way up in central Ohio with rain to the southeast and snow to the northwest of the freezing rain. Indianapolis had 4″ of new snow.
As you can see on the map, it’s really cold over much of the Central and Western U.S. Look at some of these chilly high temperatures: -9 Glasgow and Miles City MT, -5 at Dickinson ND, 1 at Watertown SD, 6 at Scottsbluff NE and Colorado Springs CO, 9 at Minneapolis, 12 at Goodland KS, 15 at Dalhart, TX, 18 at Spokane WA, 41 at Las Vegas NV, 50 at Tucson AZ and 57 at Phoenix AZ. Denver had a high of 56 on Wednesday and only 8 on Thursday.
Overnight Model update: Both the European and GFS give G.R. 0.08″ of snow Sunday night or 1-2″ of snow. The NAM is higher at 2.7″. the GFS has another 0.16″ from Monday to Thursday…or probably about 4-5″ for the 4 day period – with drifting – it gives us winds as high as a steady 29 mph on Tuesday. The European has the coldest temperatures Weds. evening. The NAM high temperatures for the next 3 days are 27, 22 and 28. The European would have an additional 1-2″ of snow Tues. to Thurs…enough to keep the roads slick at times, esp. with drifting.
