FORECAST UPDATED: 1:15 pm EST Thursday January 16, 2014 by Mike Baldwin (baldwin@purdue.edu)

Summary: Snow showers expected statewide during the day on Friday, accumulating snow on Saturday.

Much colder air returns for Friday behind today’s cold front, bringing snow showers across most of the state during the day on Friday. With the very cold air aloft, these could be convective in nature, resulting in snow squalls that will reduce visibility locally at times. Only minor accumulations are expected (1” max), although winds in the 15-20 mph range and cold surface temperatures will produce some blowing snow that could continue to deposit on the road surfaces in locations with fresh snowfall.

The next fast-moving storm system is expected to move through the state on Saturday, bringing accumulating snowfall over a large portion of the state.  Temperatures are expected to remain relatively cold with this event, which should produce low density snowfall that will accumulate quickly within the main snowband.  Forecasts continue to vary with the exact location of the track of the low pressure system.  Expect the heaviest accumulation just to the north of the track of the low, with snowfall totals in the 3-6” range at a maximum.  Snowfall amounts will rapidly taper off to the south of the track of the low, with around 1” of accumulation expected.  This storm will move in from the northwest, with snow beginning in the LaPorte district at around noon on Saturday, and move quickly to the east/southeast during the day.  The duration of Saturday’s snow is expected to last for 8-10 hours, with the snow exiting the southeast corner of the state shortly after midnight on Sunday morning.  Blowing snow will also be a major factor with this system, as winds are expected to gust up to 25-30 mph during, and after the snowfall.  At this point the heaviest snowfall (4-6”) is expected to fall north of U.S. 24, moderate amounts (2-4”) between U.S. 24 and I-70, and only minor accumulations are expected south of I-70.  We will update this forecast as newer information arrives, since there is still considerable uncertainty regarding the track of the low as well as the total snowfall accumulation.

Dry weather is expected for Sunday, however the long-range forecasts are indicating a strong cold front will push through the state on Monday.  An extended period of north/northwesterly winds are predicted to occur early next week, which could produce accumulating lake-effect snow late Monday into Wednesday across northeastern LaPorte and northern Fort Wayne districts.  Sub-zero morning temperatures are possible for Tuesday and Wednesday.  The next chance for more widespread snowfall is not until next Wednesday, with minor accumulations expected.Forecast text goes here
