Snow winding down, heavier storm possible this weekend
The last batch of snow will continue to dive southeastward this evening. But a bitter northwest wind and temperatures in the teens will keep roads snow covered and slick. A fresh 4″ to 6″+ snow pack and a clearing sky overnight will drop lows to near or below zero by sunrise Friday morning.
Wind chill values will be below zero for much of the evening and early Friday. Despite a bright a sky, daytime highs will remain nearly 20 degrees below normal tomorrow.
Friday and most of Saturday will remain quiet and mostly sunny. But long-range computer guidance remains steadfast on putting Central Indiana in a heavy snow swath Saturday night and much of Sunday.
At the very least snow is likely Sunday, and significant accumulation (much more than today) is a "possibility" based on the persistent forecast guidance.
This is all sets us up for a dangerous cold snap next week. A potentially record-breaking air mass could deliver temperatures in the -10 to -15 range and wind chills of -25 to -40. This would be the coldest temps in some 20 years for Central Indiana.
Another snow event is possible on the heels of the bitter blast later next week. No doubt an active start to January and 2014! Be safe if you're traveling this evening
