The record low tonight is 48 set way back in 1903. At the Avoca airport, where records are determined, we expect tonight’s low to be 51. However in the normally cooler outlying areas readings will indeed drop into the mid and upper 40s under a blanket of very dry Canadian air. I’ll go with 43 up there in Lopez tonight.
Tomorrow is guaranteed to be sunny with continued low humidity. Over the weekend the humidity will trend upward with showers possible Saturday night and again Sunday night. On Monday another cold front will move through with more rain and storms followed by cooler highs in the 70s Tuesday and Wednesday next week.
