Issued at 349 AM EST Sat Jan 31 2026 - Quieter next 7 days with some moderation in temperatures We have had some light snow after midnight which makes the 18th straight day of at least a trace of snow at the NWS Grand Rapids office. During those 18 days we have measured 32 inches of snow. To say the least, it has been active. Today will also mark 14 straight days being below the freezing mark (32f). If you are tired of the cold and active winter weather the next 7 days are an improvement. We will see highs work back into the 20s and we will push towards the freezing mark on a few days as well. We will have much better driving conditions overall as some sunshine and moderating temperatures will allow for road crews to apply salt which will be more effective. Two main system are in the pattern, both of which are clippers, one on Sunday night/Monday and the other Thursday night/Friday. - Clipper system moves through Sunday night into Monday The first clipper will move through Sunday night into Monday with a shearing upper wave and moisture that is not all that deep or sustained in time. There will be enough lift and moisture however to produce some snow across the entire forecast area ranging from a half inch near Lansing and Jackson to an inch or two along the Lake Michigan shoreline. Delta T`s are just enough around 13C to aid in lake enhanced snow across Western Lower Michigan. The highest snow totals will be found from Grand Haven north up the shore due to southwest flow and the fact that the colder are will be found there. This will not be a significant snow, especially given what we have experienced the past two weeks. That said, the Monday morning commute will likely be affected from the Grand Rapids area to the north and west. - Another clipper system moves through Thurs night and Friday A stronger clipper system is forecast to move through the region Thursday night into Friday. The early week system a 1010mb low passing well off to our north over Ontario. The end of the week system as a 997mb low moving through Lower Michigan. The heaviest snow with clipper systems are usually near the track of the low. This system is 6 days out and as such there are model differences. The GFS tracks the low north of us, while the ECWMF takes the low on a further south track right through Southwest Lower Michigan. The GFS track would bring us some snow but amounts would be light. The ECMWF track would bring several inches of snow to the bulk of the forecast area. Suffice it to say we will be watching trends with this system. && .AVIATION /06Z TAFS THROUGH 06Z SUNDAY/... Issued at 1150 PM EST Fri Jan 30 2026 Snow is moving across southwest Lower Michigan with MVFR and areas of IFR but trends will be for improvement as the snow diminishes after 06Z. VFR can be expected by 12Z and continue into Saturday afternoon. WInds will be northwest to north AOB 10 knots. && .GRR WATCHES/WARNINGS/ADVISORIES... MI...None.
