KEY MESSAGE 1...Dry and seasonable conditions continue through early next week, with frost possible this weekend.
Surface high pressure remains to the north through Saturday with dry and seasonable conditions expected to continue. Tonight's low temperatures will be in the upper 30s to 40s. For Friday and Saturday, surface high pressure extends southward from Canada with dry cold fronts bringing in cooler air. High temperatures stay in the 50s to low 60s while overnight lows plummet into the 30s for most. The exception will be east of the I-95 corridor where low temperatures stay in the low 40s. Frost is possible Friday night and Saturday night.
High pressure will continue to build southward into the region Sunday through Tuesday. Dry conditions and seasonable temperatures expected each day with light north to east winds. A backdoor cold front could try to push into the region Tuesday into Tuesday night, but will have very little to no moisture with it to produce any precipitation. A surge of cooler temperatures will follow behind the front for the day on Wednesday.
