Monday highs will be in the 70’s with isolated showers and thunderstorms possible. Lows will be in the 50’s.

Tuesday dry weather will return with temperatures in the 80’s.  Lows will be in the mid 50’s to low 60’s.

Wednesday temperatures will be in the 80’s, with a slight chance of showers. Lows will be in the mid to upper 50’s.

The five-day precipitation amounts will range from ½” to 1 ½” , falling Sat- Sun.

The 8-14 day outlook (September 22-28) shows increased chances for above-normal temperatures for all of the state and above-normal precipitation for all but part of the Catskills and Hudson Valley Region.

The Drought Monitor: Despite the heat and dryness, heavy downpours (locally more than 2 inches) led to some drought reduction in southwestern New York and Jefferson County. D1/Moderate Drought expanded in the Adirondacks, Lake Champlain, and Hudson Valley regions.
