FORECAST UPDATED: 1:15 pm EST Thursday January 16, 2014 by Alex Coffman (jcoffma@purdue.edu)

Summary: Light snowfall potential continues into the day on Friday, then more snow possible this weekend.


    Current model simulations show two separate opportunities for snow across the state on Friday. Temperatures will start out Friday morning very cold over parts of the state, with temperatures possible in the single digits in the LaPorte and Fort Wayne districts. Winds will cause single digit wind chills over the northern 2/3rds of the state, and possible near or below zero in the LaPorte and Fort Wayne districts. Any precipitation that is melted on pavement will likely freeze tonight, so slick spots could develop.


    The first snow chance across the state will be over central and southern Indiana in the morning hours. This is where the most concentrated area of snow will be. Current model projections are showing a small band of heavier snow is this area tomorrow morning. Generally, no more than an inch or 1 ½” should be expected from this, however, the heavier snow band could prompt some 2 inch amounts in the morning.


    As that band of snow moves into Ohio, another band of wrap-around moisture will move into northern and central Indiana, bringing light snow, some of it lake enhanced. I would expect snow totals to be no more than an inch, with the focus of this snow being north of Indianapolis. Along the lake, some isolated higher amounts will be possible. Also, blowing snow will likely occur because of the light fluffy nature of the snow, coupled with wind gusts over 20 mph.


    Looking into the extended forecast, Saturday will bring a better chance of accumulating snow across parts of the state. It has been difficult to determine where the most snow will be, however parts of the LaPorte, Fort Wayne, Greenfield, and the northern part of the Crawfordsville district will be where the most accumulation is expected to occur. With the cold temperatures and high snow ratios, some areas of 3-5” or possible 6” should be expected where the heaviest snow occurs. We will bring a more detailed update tomorrow when there is more certainty with the forecast.


    After that storm system, cold weather shall persist, with the continued possibility of light snow from time to time, as well as icy roads. However, no significant storm systems are on the horizon after Saturday.
