Other than isolated flurries to start the day, it will be a dry day for most locations. High temperatures will end up in the mid-20s to upper-20s as we creep out of the colder air. The southwest winds will increase to 10 to 20 mph. The arctic airmass which has prevailed over the past week will move away from the region so it will not be as cold for the remainder of the week.
The days ahead will bring a noticeable warm-up with temperatures trending into the low to mid-40s. Rain is possible on Thursday, then periods of rain are likely during the Friday–Saturday timeframe. Any snow we have on the ground will take a noticeable hit. Above-normal temperatures may last through mid-January.
Yesterday we reached 26° with about an hour of partly sunny skies, the morning low was 13°.

- Quiet Through Wednesday, Some Peeks of Sun Possible Residual flurries and light snow showers will come to an end today as mid level heights rise, advection of warmer 850 mb temperatures begins, and sfc winds turn S/SW. Some breaks in the clouds are possible especially near and south of I-96 based on our national blend of models as well as ECE guidance. You can also see this via the RAP13 RH layer analysis, with low level moisture (ie. 925 mb RH) dropping significantly from south to north today and tomorrow. So far this month, Grand Rapids has averaged 11% of possible sunshine. - Warmer Temperatures, Fog, and Light Rain Moving Our Way Excellent prognosis from the previous discussion to include fog potential beginning Thursday. We`ll see higher dew points (40F-45F) advect in on Thursday overtop a snowpack that is in place across the region (deepest near/west of US 131). Model guidance supports a period of light rain or drizzle Thursday into early Friday ahead of a cold front that will likely move through Friday morning. This period of warmer surface temperatures and dew points in the 40s combined with some light rain and drizzle should be conducive to fog development. The GFS is showing potential for dense fog as well. Also, as previously mentioned, this setup could cause a problem on roadways. Current pavement temperatures are in the teens to low 20s. These likely won`t change much today given highs in the 20s away from the immediate lakeshore. Pavement temperatures should warm on Wednesday with highs above freezing, but it is questionable whether pavement temperatures get above freezing before fog and light rain move in Thursday. As a result, especially secondary and rural roads could have some slippery travel Thursday. Model spread exists from Friday into Sunday with regard to precipitation chances and even, to some extent, precipitation type. However, the general expectation is that the cold front that moves through Friday will likely stall out over southeast Lower MI or just south of our border. This occurs as another 500 mb shortwave will approach the state. The ECMWF favors a LLJ to be pointed more toward Ohio and southeast Lower MI than our area, whereas the GFS is further west (and wetter) and the GEM is showing very little precipitation at all. You can see the spread in the ECE/GEFS/CMC ensemble solutions as well, indicating some uncertainty in where the front stalls and heavier precipitation sets up Saturday into Sunday. Given the superior performance of the ECE this winter, would tend to favor the more progressively eastward moving front and higher rain chances across southeast Lower MI over the weekend. There is potential for mixed precipitation (rain, snow, and freezing rain at times) to occur across mainly central Lower MI especially at night with this synoptic setup. With regard to significant rainfall (1" or more) through the weekend, odds are decreasing. The ECE shows less than a 20% chance as does the CMC. The GEFS is higher at 30% but is clearly trending toward the ECE and CMC. My observation is that the ECE typically leads the pack in showing correct trends. Good model consensus exists with regard to a more potent upper wave moving through by next Monday or Tuesday with increased odds for surface low development and another round of rain (most likely) as low level warm advection intensifies.
Wow, what a great day to get outside and ski, snowmobile, etc! Skiing here I come baby! Incredible storm and an incredible start to winter! This could be the most snow by this date in GR ever! Winter rocks!
As of today Grand Rapids has had 67.6″ that is good for 3rd place as of this date. 2000 is in 1st place with 80″ and 1951 is in 2nd place with 78.2″

Wow, Detroit is still reporting below average snowfall for the winter. Still no big synoptic snows I guess outside of the lake effect areas.
Many locations outside of the lake effect areas are below average in snow fall. They include Saginaw in Michigan, Chicago and Rockford in IL, Milwaukee in WI, Fort Wayne in IN, Toledo and Cleveland in OH, and even Rochester in NY.

Wow! A tale of two different winters.
I like the headline of this post. I shoveled yesterday again morning and I think SS mentioned this: that was the lightest, fluffiest snow I’ve seen in a long time. The sun broke through for a bit yesterday afternoon. It helped to remove some of the frozen white stuff from our driveway.
The official H/L at Grand Rapids yesterday was 23/16 there was a reported 0.3” of snow fall that bring the seasonal total so far at Grand Rapids at 67.6” There was 13% of possible sunshine and there was 15” of snow on the ground as there has been some melting from the ground up as the ground is not frozen here. The overnight low for today so far has been 17 and at the current time there is light snow falling and 21. For today the average H/L is 33/22 the record high of 60 was in 2008 and the… Read more »
