High pressure will build into the region, which will keep the weather dry through the upcoming week. Warm conditions are also expected during this period, with daytime highs solidly in the 70s and a few 80 degree readings possible at times, especially Monday and again Friday into Saturday. A cold front will track through the region Monday night; however, it is expected to come through dry and only suppress the temperatures a few degrees through the middle of the week before they rebound again.
Winds will pick up a bit out of the southeast Wednesday night into Thursday, leading to possible marine concerns (Small Craft Advisories) on Lake Michigan, especially south of Two Rivers.
