A Blizzard Warning goes into effect at 1am and continues until 7pm for much of Central Indiana. The last time a Blizzard Warning was issued for our area was Feb. 13-14, 2007! Expect heavy, wet snow and blowing and drifting. Winds could gust to 30 mph creating white-out conditions. The combination of sub-freezing temps and howling winds could drop wind chills to around 10 degrees. Travel will be treacherous, so if you have to hit the roads, you’ll want to do so tonight, or you might have to wait until the storm winds down Wednesday evening.
This is a potent storm packing a lot of moisture and computer models seem to be honing in on colder temps. With sub-freezing temps and the rain/snow line staying in far Southern Indiana, we’ll likely see “all snow” here in the Indy Metro. That, combined with liquid amounts in excess of 1″ could mean 10″+ of heavy, wet snow. Right now, it looks like the jackpot totals of up to 15″ might be in areas like Shelbyville, Columbus, and Greensburg. Snow totals will drop as you head to the north and west, with a half foot possible for Crawfordsville and Kokomo and up to a foot for Carmel and Fishers. This forecast isn’t set in stone, but we could be dealing with one of the biggest December snowstorms on record. The biggest was 13″ on December 20th, 1973.
Temperatures may start out in the low 30s first thing in the morning, but colder air wraps into the storm during the day Wednesday, which means temps falling into the upper 20s during the day. Winds sustained out of the northeast around 20-30 mph with gusts to 40 are possible.
The cold sticks around for your WTHR 7-day (the snow pack makes it harder to warm up since the sun’s energy goes into melting the snow rather than warming us up.) Another storm approaches late Friday night and Saturday. At this point it looks much weaker and could bring anywhere from a coating to a few inches of additional snow, subject to change.
Stay safe and grab your snow shovels!
