Winter Weather AdvisoryJanuary 30th, 2014 at 2:46 am by Bill Steffen under Bill's Blog, Weather
We have a Winter Weather Advisory in effect until 10 PM. The advisory covers blowing and drifting snow this AM, then the snowfall that arrives from NW to SE across the area during the afternoon and evening. Snowfall totals could reach 3-4″ north of Muskegon with an inch or inch and a half southeast of Grand Rapids. The wind will be a major player today, out of the south. The GRR NWS discussion says: ” THE COMBINATION OF FALLING AND BLOWING SNOW WILL MAKE FOR VERY HAZARDOUS CONDITIONS. WHITEOUT TO NEAR BLIZZARD CONDITIONS COULD BE SEEN AT TIMES.” Both the NAM and GFS models have the wind peaking around 4 – 5 pm at 24-26 mph with gusts in the 40 mph range. That will cause a lot of blowing and drifting snow, especially on roads that run east-west. The falling snow won’t start until this afternoon. The worst will probably be from 3 – 8 pm. Both the NAM (caribou) and the European give G.R. about an inch and a half of snow starting around 4 pm in G.R. (earlier to the northwest) and ending before daybreak on Friday. Other snow totals off the NAM (caribou): Ludington 2.8″, Muskegon 2.1″, Holland 1.6″, Kalamazoo 1.3″, Lansing 0.7″. With the drifting, you’ll get more than that in your driveway. The winds are much lighter on Friday, about 6-12 mph. Saturday’s snowfall comes to 2.4″ for G.R. on the NAM (caribou). The European prints out 0.37″ of precipitation – that would be about 5″ of snow falling from late Friday night (Friday evening should be dry) into Saturday. The European also prints out 0.22″ for G.R. from the low pressure center that will pass southeast of us Tues. night into Weds. morning. That would be another 3-4″ of snow with another push of Arctic air next Thursday. We also have Gale Warnings for Lake Michigan today. It’ll be interesting to see if the wind breaks up any of ice on the Great Lakes. The GEFS has the cold weather hanging around into the 2nd week of February (and probably beyond). 233 miles now — all of Interstate 10 from Pensacola to E of Tallahassee closed due to extreme ice. Here’s snow on the ground at the Augusta (GA) National Golf Club.
Afternoon HIGH (not low) temperatures: 43 Brownsville TX, 41 Galveston TX, 35 New Orleans, 31 Mobile AL, 30 Pensacola FL, 25 Dothan AL, 27 Albany and Macon GA, 32 Savannah GA, 30 Charleston SC, 37 Jacksonville FL, 48 Monterrey, Mexico (average high 70 – they were in the upper 80s on the 26th and 27th), 49 Saltillo, Mexico. Temperatures held in the 60s down past Veracruz.
