Climate Prediction Center outlooks indicate near normal temperatures and favor slightly above normal precipitation. Large-scale atmospheric patterns favor occasional dips in the jet stream across eastern Canada and the Northeast, which could bring brief periods of cooler weather even as temperatures average near normal overall. Normal temperatures at Fort Kent and vicinity during this period are in the lower 70s for highs and upper 40s for lows.
