No huge changes to our initial snowfall forecast ideas, but the Winter Storm Watch for Central Indiana has been replaced by a Warning by the National Weather Service in Indianapolis.
We’re still expecting snow to arrive Tuesday afternoon and be heavy between the hours of 6pm Tuesday and 3am Wednesday…. when snow rates of one to two inches per hour are possible.
This will make road conditions deteriorate very rapidly Tuesday evening. School delays and closures are likely Wednesday due to this storm. Despite the fact we’re 24 hours away from the first flakes, there is still uncertainty on the exact track and how far north the snow/sleet/freezing lines will travel.
For now we’re still anticipating the heaviest snow totals to occur north of I-70, where six to 10 inches looks likely. If Indianapolis remains all snow then focus on the top range of the forecast… meaning seven inches would be most likely. We are concerned about the threat of icing (quarter inch or more) along and south of Bloomington-Columbus-Cincinnati line.
Like with any winter storm this map and forecast are subject to significant changes. Check back Tuesday morning for an update.
Snow will depart by Wednesday afternoon and bitter cold air returns for the later half of the week. We’re already keeping tabs on another potential snow maker for the weekend, and we’ll sort of the details after we get through this first storm. Thanks for reading the blog – Sean Ash
