The Frost Advisory has been expanded to include the central counties all but the southeastern counties of the state. NWS La Crosse has elected not to issue an advisory mainly due to the normalcy of frost through the middle of May in those areas. Temperatures will drop into the lower 30s during the morning hours on Sunday. This could damage plants that have already been planted or are outside. If you are able to bring them inside, it would be a good idea to do so, otherwise cover them up. Temperatures should warm into the upper 30s and lower 40s by mid morning.
