Weekend Snow Forecast: A winter weather system is set to move into the Valley beginning late Saturday through Sunday evening.
A Winter Storm Watch will go into effect for most of central Indiana including Vermillion-Parke-Putnam-Owen-Clay-Vigo counties from 7 p.m. EST Saturday through 7 a.m. EST Monday, and Douglas-Coles-Edgar counties in Illinois from Saturday evening through Sunday evening.
These locations will see the highest snowfall totals ranging from 6-8″.
Rain will be possible at first mainly after 3 p.m. EST on Saturday as temperatures will still be in the upper 30s. As colder air rushes in, this changes into a wintry mix of mainly snow through the overnight.
By daybreak on Sunday, light accumulations will be possible as the heaviest of snow will come Sunday 7 a.m. – 2 p.m. EST. Precipitation clears by Sunday evening.
Accumulations will vary widely from north to south. Highest snowfall totals will be north of I-70 in the 6-8″ range from places like Paris, IL through Vermillion, Parke and Putnam counties in Indiana. This is where the forecast confidence is highest.
Confidence is lower through the I-70 corridor, from Effingham through Casey, Terre Haute, Brazil and Bloomington, IN, where temperatures will push the freezing mark on Sunday causing rain to potentially mix in cutting down overall snowfall potential. Look for a 3-6″ snowfall range, with Terre Haute on the higher end of that scale. Keep in mind that if we see more rain mixing in, snowfall totals will be much less than the projected 3-6″.
Lower amounts stay south where more rain will mix with snow, reducing overall accumulation. Southern Martin-Daviess-Knox counties (in Indiana) and southern Lawrence-Richland-Clay counties in Illinois we see snowfall totals from 1-3″.
**These snowfall predictions are based off of Friday afternoon weather models. Updates to come could impact these projections as we get closer to the actual event. Check back with us for the evolution of this system over the next 36-48 hrs.**
