Our latest bout of snowfall has certainly reached Greater Lafayette; heavy snowfall already affecting our northern half of the viewing area will continue to track due east, while another wave of organized snow continues to inch its way eastward across the southern half of the viewing area.
According to the Strom Prediction Center of America, this system “should continue to yield snowfall rates up to one inch per hour as the band advances east. However, rates should gradually diminish later this evening and with eastward extent.”
Current model data suggests that we’ll see our heaviest snowfall in Lafayette around 10:00 P.M. ET, though expect the snowfall to gradually intensify as that hour draws nearer. The last of the snowfall should exit Tippecanoe County about 2:00 A.M. ET before exiting east of our region around 2:30 A.M. ET or 3:00 A.M. ET.
By the time it’s all said and done, portions of northwestern counties could be left with as much as 4” of total accumulation. Considering how quiet it has been around the area as of late, this is no slouch of a system. I’m expecting between 1.5” and 2” for Lafayette and West Lafayette but less than an inch for parts of our southernmost counties.
Unfortunately, this isn’t the last of the snowfall on our extended forecast, there appear to be two more low pressure systems in our cards with snow chances written all over them. The first low will supply snowfall to the area expected to be hit hardest this evening, our northwestern counties, beginning late Tuesday evening. This round will last through sunrise on Wednesday and will drop an additional 1“-2” of accumulation. Another low heads our way Thursday evening into Friday morning, possibly packing another snowy punch.
