FORECAST UPDATED: 1:00 pm EST TFriday January 16, 2014 by Blake Cotcamp (bcotcamp@purdue.edu)

Summary: Lake-effect snow to affect the northern districts on Friday, with a chance for some light snow showers over the central and southern parts of the state. A system arriving on Saturday has a chance to bring more significant snowfall totals.

As the clipper system that affected the state on Thursday moves out of the region, colder air will spread across Indiana beginning early Friday morning. With this cold comes the likelihood of some lake-effect snow over the northern districts and some potential snow showers over over the central and southern portions of the state. This lake-effect snow in the will affect the northern districts and snowfall totals could range from 0.5-1”, with higher chances for accumulation in the northern parts of the Fort Wayne and LaPorte districts. Temperatures will be in the low 20’s during the day with winds gusting from 20-25 mph, which could produce some blowing snow in the northern districts.The central and southern parts of the state will experience smaller snowfall totals that could range from a light dusting to no accumulation at all.

The bulk of the colder air will move out of the state by the end of Friday, as another clipper system moves into Indiana on Saturday. This system has the potential to produce significant snowfall over the northern portion of the state, ranging from 4-6 inches in the Fort Wayne and LaPorte districts, and 2-3 inches in the Crawfordsville and Greenfield districts. However, the models are still in disagreement over the track of this system, and a more northerly track of this clipper would result in much lower snowfall totals. The beginning of next week looks to have near-average temperatures in the mid to upper 30’s and should remain dry until another clipper system is forecasted to move through Indiana on Tuesday.
