Cool and Dry PatternDecember 22nd, 2012 at 3:07 am by Bill Steffen under Bill's Blog, Weather
S. Haven early Friday by Rick at ReportIt. This was close to the time that the S. Haven Lighthouse weather station recorded a gust to 71 mph. That’s almost up to Hurricane (75 mph) strength! You can see the wind pushing the spray to the south. The satellite loop shows both high clouds passing by. You can also make out the snow on the ground from the lake-effect band from Holland to Indiana. 33 degrees and some sun, so a little snowmelt going on. Snowcover: trace in Grand Rapids, 1″ at Muskegon, Ionia, Lansing and Hesperia, 2″ at Hart and Big Rapids, 4″ at Scottville, 6″ at Houghton Lake, 7″ at Lake City, 8″ at Beulah, 4 to 12″ around the Traverse City area, 12″ S. Ste. Marie, 14″ Gaylord, 15″ Marquette, Grand Marais. The wind has calmed down and should be west at 10-15 mph today and down to 5-10 mph for most of Sunday. We’re into a cool and dry pattern. The NAM (caribou) gives G.R. highs of 33, 35, 33 over the next 3 days. The GFS is 32, 32, 28. The GFS would give G.R. around 1/2 inch of snow Thurs. and the European has a half to one inch Christmas Eve Night, another inch on the 26th and 11 degrees early Thurs. AM. Both models have about 1-2″ of snow next Saturday. The GFS (it’s the GFS) has a shot of Arctic Air around 1/3 with temperatures down in the single figures. Note: It’s hard to get to zero in G.R. without a solid snowcover. Speaking of snow cover, early Friday Traverse City had 10″ on the ground, with 12″ at S. Ste. Marie, 15″ at Marquette and 16″ at Grand Marais. Cool high temperatures on Friday: 63 Orlando, 61 Tampa, 46 Atlanta, 9 Grand Forks ND, 8 International Falls MN. The past 3 days Las Vegas has had highs of only 48,47 and 50. Oymyakon, Russia has had low temperature the past 4 mornings of -65F, -66, -63 and -61. Cannonsburg Ski Area is going to try and open on the 26th. Congratulations to Pando on their 50th year – they are hoping to open on the 26th as they make snow. Ski resorts north of U.S. 10 are generally open now with fresh natural snow.
