INDIANAPOLIS, Ind. (Jan. 11, 2016)--Good Monday afternoon. Temperatures at the 2 p.m. hour are in the teens and low 20s. Wind chills are in the single digits for many. Flurries were reported across parts of central Indiana.
A warm front will lift north across the area this evening bringing a rise in temperatures to the upper 20s and low 30s through midnight Tuesday. In fact, the highest temperature all day Tuesday will be around midnight. A clipper system will move in and bring snow showers and snow squalls to the area starting across northern Indiana this evening and then central Indiana later tonight into Tuesday. Expect the possibility of sudden changes in visibility with heavier bursts of snow and blowing snow as winds will howl gusting to 35 and 40 mph. Road conditions are already bad in neighborhoods and main roads will get bad fast with additional snowfall.
A cold front will move through Tuesday morning and drop temperatures back into the teens during the day Tuesday. Winds will gust to 35 mph with a wind chill back in the single digits Tuesday afternoon. Snow showers and snow squalls will continue into Tuesday morning's commute and last through the afternoon.
Clipper systems make it hard to predict exactly where the heaviest snow bands will be due to the fast-moving nature of the system and the squalls that take place during them. However, despite weak, warm-air advection tonight, I still believe snow-to-liquid ratios could be anywhere from 15-20 to 1 leaving central Indiana the possibility of 1-3 inches of snowfall. This ratio means that it will not take much liquid precipitation to result in heavy snow amounts. It wouldn't surprise me to see some places on the higher end of that snow range. In fact, the heavier band of snowfall may set up in and around Indianapolis based on the position of the jet stream.
As mentioned before, temperatures will fall through Tuesday morning with a temperature near 20 degrees at daybreak and teens Tuesday afternoon.
The coldest air of the season will arrive Wednesday morning as the sky clears and the winds relax. Fresh snow on the ground will allow temperatures to plummet close to zero in spots. Flurries are possible in Indy Wednesday with light snow north. Temperatures into the weekend will rise to the low 40s Friday with rain. There's a chance of a rain/snow mix on Saturday and snow chances Sunday into Monday. Welcome, winter! --Danielle Dozier
