Snow showers will mostly clear out by mid-morning on Sunday. Isolated lake effect snow will be possible throughout the day. Finally, Sunday night snow chances will clear and then we are left with bitter cold temperatures. Highs Sunday afternoon will only top out in the upper 20s. Lows Monday morning will drop into the single digits for some. Highs will slowly warm back into the 30s for the middle of the week, but then another round of snow and bitter cold moves in Wednesday into Thursday.
If you are traveling to other parts of Indiana, expect a lot precipitation, as well.
“That area between, say, a line from Knox to Goshen, and then north of U.S. 24…that’s kind of our ‘uncertain zone’ at this point,” said Meteorologist Chris Roller with the National Weather Service of Northern Indiana. “Northeast Indiana could get more of a wintry mix, making the snowfall totals lower.”
“I got a 1-3 inch snowfall total in Warsaw, about 1-2 inches in Fort Wayne,” Roller said.
Central portions of Indiana can expect mostly rain on Saturday, although Roller doesn’t rule out the possibility of it changing to a light snow on Saturday night.
Southern Indiana will be dealing with flooding, as areas along the Ohio River could get 2-3 inches of rain this weekend.
The temperatures are the other key ingredient to this weekend’s weather system. Roller says even if your area only gets rain for most of Saturday, the temperatures will drop low enough to make roads slick.
“One of those things where you’ll want to drive around with some caution Saturday night and into Sunday.”
It will be windy across the entire state on Sunday, making feel-like temperatures in the upper 20s or low 30s for the southern half of the state, and in the teens for the northern half.
