A clipper system moves across the region today and will bring a fresh round of snow to a large part of the state. We expect a coating to 2 inches in most places, and some locations in northern and northeastern Indiana may see closer to a 1-3 inch range. Still, this is not expected to be a big deal, as the system moves fast, and the available moisture is limited. Winds will not be much of a factor during the event. By evening, most of the state will be done with the light snow, and by midnight all action will be off to the east and south.
Behind this front is a reinforcing shot of cold air that holds through most of the rest of the week. We can see some subzero temps tomorrow night into Wednesday morning as skies clear, and we see highs doing no better than mid-teens to mid-20s through Thursday. Friday we may get back closer to normal for this time of year. The week will be dry, and we do expect sunshine to be a big player, much like we saw yesterday. Sunny and cold will describe most of this week.
Strong southwest winds bring moderating temps back for the weekend. We go above normal Saturday, and stay there Sunday as winds strengthen ahead of our next front. That front brings rains from .25”-.75” to 90% of the state from midnight Sunday through midday Monday. The map above shows a snapshot of action from Sunday night. Rains in Michigan and northern Indiana are a little overdone, in our opinion, on this map, and we are going with a more conservative approach to this system However, the geographic spread show here matches our thoughts.
Temps cool slightly behind that front for early next week, but we do not see cold arctic air returning. Instead, temps stay near normal for most of next week. South winds are back at midweek, suggesting that another strong system is in the works out in the plains. Indeed, in the extended 11-16 day period we see a massive system coming together in the 4 corners region late Friday, the 26th, and then it slowly churns eastward. This significant storm looks to move into our region around the 28th, and will have liquid equivalent precipitation potential of half to 1.5”. Currently, the track of the heaviest action is well south of us, crossing the Deep South, but a system like this needs to be watched as it evolves. The map above shows one solution of where this front can be Sunday morning, 1/28. Behind it we likely see cold arctic high pressure returning for the finish of the month and start of February. The cold air should come in stages…the initial push behind the front for the 29th and 30th, and then a colder shot behind a clipper we think could emerge around the 31st into the 1st.
