A Winter Weather Advisory went into effect at noon today until for central Indiana. This will equal a messy evening commute.
At 2:30 pm, all precipitation types were falling across Central Indiana, with sleet and freezing rain the flavor of choice in the Indianapolis metro area. Ice accumulations of a .10″ to .20″ becomes the concern for the I-70 corridor and snow amounts appear to be less than an inch by 8pm.
With some places not climbing to the freezing mark this afternoon, untreated roads will likely get icy… especially north of Indianapolis where there is a higher chance of staying sub-freezing.
Farther north, and especially northwest, moderate/heavy snow and sleet continue to fall over Lafayette and Kokomo…and thunder remains a possibility in this dynamic atmosphere. Areas of mostly snow will see 3″+, while cities like Bloomington, Columbus, Seymour and Bedford deal with a cold rain and temperatures elevating into the mid-30s.
We've made adjustments to our snow/ice zone map, but still believe a quick accumulation of snow/sleet is possible in the Indy metro before a transition to freezing rain occurs.
Remember a few degrees can change conditions dramatically over any given area, and the precipitation will occur in a narrow window between now and 7pm.
Tomorrow and Wednesday we warm into the 40s.
Thursday, the 50s with thunderstorms.
Flooding will be a big concern, along with a few strong storms, so we'll keep a very close eye on the forecast as we get closer to this event.
The National Weather Service in Chicago has issued a Winter Storm Warning for heavy snow from 10 a.m. EST Monday morning to 10 p.m. EST Monday evening for Benton and Newton counties in northwest Indiana as well the Chicagoland area.
Snow will develop by mid-morning and taper off later in the evening. Accumulation potential has increased for some locations to receive totals greater than 6 inches. Exact snowfall amounts will be updated throughout the morning.
Snow will fall heavily, with snowfall rates possibly reaching two to three inches per hour for a time, especially early this afternoon. This will cause snow-covered roads with near zero visibility at times, making travel very hazardous across the region.
Travel through Chicago O'Hare and Midway airports could also be significantly impacted.
A Winter Storm Warning for heavy snow means severe winter weather conditions are
expected or occurring. Significant amounts of snow are forecast that will make travel dangerous. Only travel in an emergency.
