Temperatures tonight will be dropping down into the upper 30s here in Louisville with mid 30s possible in the suburbs and outlying areas. This presents a threat for patchy frost in those areas that get cool enough. So far a Frost Advisory hasn't been issued but one may come out later today for the overnight hours into Thursday. After this frosty start we'll start a warming trend that will take us into the 70s by the weekend! Check out the full details of the extended forecast in the video below.
