Sunday AM – Still a few slick spots, nothing you can’t handle. Watch for an icy spot on sidewalks, driveways and parking lots that have not been salted. We continue to see scattered light snow showers and flurries, mainly west of US 131. The Sun. AM European data has a general light snow starting Sunday night (not much until after midnight, so many roads still OK early Sun. evening. The model gives G.R. 0.22″ of precipitation from late Sunday night through Tuesday, so a general 2-4″ snowfall. It stays cold thru Weds…moderates for Thurs. into next weekend. The European takes the temp. back up to 45-50 briefly over the weekend. The GFS plot also has 45 for next Sunday…then colder after that. From the Detroit (White Lake) Sunday morning forecast discussion: “..A CONTINUED MODERATION INTO NEXT SUNDAY AS A SIGNIFICANT STORM SYSTEM EJECTS FROM THE WESTERN TROUGH INTO THE AREA. THERE IS SOME SUGGESTION THAT THIS MAY BECOME THE DOMINANT UPPER PATTERN FOR THE REST OF THE MONTH WHICH WOULD BRING A MILDER (AND STORMIER) PATTERN TO THE REGION AS COMPARED TO OUR RECENT BOUTS OF RELATIVELY PERSISTENT ARCTIC AIR.”
Season Snowfall: 63.2″ Muskegon, 40.1″ Grand Rapids, 39.6″ Kalamazoo, 22.3″ Lansing. Here’s Matt Kirkwood’s snow condition report. Through Saturday, Grand Rapids is 5.7 deg. cooler than average for January. Here’s Ellen writing about the biggest 24-hour temp. drops ever in G.R. (note they are mid-winter to very early spring).

Embarrass MN has been below -40 five mornings this month, more than 12 deg. below avg. for the first 13 days of Jan.
High temperatures Friday were unseasonably warm in the East (see map up top). It was 61 as far north as Burlington VT and the temperature reached 70 at Washington D.C. and 71 at Martinsburg WV. Cold air dominated from the Western Lakes to the Northern Rockies, with daytime highs below zero from N. Minnesota to E. Montana. The GFS model high temps. for the next 8 days are 20, 24, 24, 23, 25, 30, 32, 37. Mostly light snow will fall from Sunday night thru Tuesday with about 2-4″ accumulation. That cold arrow comes right over Lower Michigan. Also, smoke from a fire in Greenville Mi could be seen on radar moving south (with the north wind) for 20 miles.
There was a line of low-topped thunderstorms along the cold front that produced 19 reports of wind damage in PA, VA and NC. Avon Pier NC recorded a wind gust to 77 mph.
This is the 8-14 day precipitation forecast from CPC for Jan. 20-26. The greatest chance of above average precipitation is forecast to be from Arkansas north to the Southern Great Lakes. That would likely be a mix of precipitation types. Looks like a good week for anyone on vacation in Florida.
