High pressure will build southward out of southeastern Canada and eastern Great Lakes region Saturday through Tuesday. Dry conditions are expected each day. There could be some areas of frost Saturday morning. Temperatures will start out chilly Saturday with highs 5 to 7 degrees below average and highs generally in the upper 50s to lower 60s. By Sunday, temperatures will be more seasonable. Monday will encounter highs approaching or reaching the 70 degree mark. By Tuesday, temperatures may be knocked down to seasonable once again. Highs in the middle 60s.
