A Frost advisory is in effect this morning, with overnight frost expected through mid-week in the Region. Daytime temperatures gradually get milder this week. The National Weather Service also says the steady, soaking rain across the Region over the weekend was much needed. Some local rainfall totals include nearly two-and-a-half inches in Hobart, Hebron and Munster through Sunday morning. The latest Drought Monitor Map from the USDA shows moderate drought conditions continuing for most of Northwest Indiana.
