Dry air at the surface should help weaken an approaching disturbance and snowfield heading this direction. The air should saturate over the Indy metro area by midnight to allow precipitation to begin. Though it may start out as light rain...most precip tonight should be the frozen variety and predominantly snow.
Most places have snowfall accumulation around/under one inch, but there may be an area of 1"-2" in west-central Indiana southward to the Ohio River. Either way, much of the accumulation occurs on grassy areas and has minimal impact on roads...at least roads that are treated.
Monday will be cloudy with drizzle and occasional rain/snow showers as high temperatures struggle into the mid-40s. Gray, and at times damp, conditions linger into Tuesday.
We're still targeting Wednesday for milder air with highs near 60 and then a gusty southwest wind delivers 70s for Thursday and Friday. However this warm up also helps feed heavy storms/rainfall Friday night into Saturday.
The warm up is also brief in nature with colder air returning Sunday as highs return to the 40s - Sean Ash
