Thurs. AM – Flurries winding down…cold start to today…models still show significant rain Friday night. The GRR NWS forecast discussion did a nice job of highlighting the impacts from the coming weather. I’ll add the possibility of icy roads Sunday morning as temps. may be a little below freezing and the ponding from the rain will likely freeze up. It’s going to be cold this morning as skies become clear to partly cloudy with light winds. We could see a brief period of light snow Thurs. night (a dusting) and there could be a little freezing drizzle to cause a few icy spots (in addition to the snow that’s already on the side streets/rural raods) Friday AM. When the rain starts the ground may be cold enough to produce some icy spots even if temperatures (taken at the 5-foot level) are a little above freezing. This will be a significant rain – maybe 1/2 to 1″ and there’s no place of the water to go…it’ll soak into the snow (and then freeze when it get’s cold enough. That may cause a problem for snow that’s on roofs or hanging from gutters (knock the snow off your gutters if you can). The water will pond on the roads (clear drains and downspouts if you can) and may freeze Sat. night, making for some very icy spots for the church commute Sunday AM. We’ll flip from above freezing to below freezing several times next week and that will also cause icy spots. We’ve got news/weather stories on impacts tonight, watch us at 5, 6, 10, and 11. Here’s current Michigan temperatures, and a national weather map. Here’s the NAM model 84-hour snowfall and GFS model snowfall thru 120-hours (not much).
Model update: The NAM and Euro have highs of around 14 today, I’m with the more optimistic GFS at 18. We still have flurries around this AM. Do we clear out and get really cold Thurs. AM? The Euro. has -6, the GFS +5 and the NAM +11 – I’m siding with the Euro. The models have a dusting to an inch of snow Thurs. night. Rain Fri. night/Sat. AM totals 0.60″ on the GFS and 0.69″ on the Euro. The Euro. has temps. rising to at least the low 40s during Fri. night and the GFS takes us to 40…I’ll stay on the cool side with all the snow we have. Watch for the rain puddles to freeze Sat. night. There could be some real icy spots late Sat. night/early Sun. AM. Sunday is a bit cooler, Monday back to highs in the low 40s – GFS is cooler, in the low-mid 30s. The models are hinting at more Arctic air sometime around the 18th-22nd.
