Dry, comfortable weather returns Thursday into the weekend.
Overnight
Increasing clouds with mild overnight temperatures. Dry conditions continue as moisture begins to increase ahead of the next storm system.
Tuesday
Clouds thicken during the morning with showers developing by late morning. Thunderstorms become more numerous during the afternoon, and some may become strong to severe.

Weather hazards for the Hudson Valley at this time.
Strong to severe thunderstorms (Tuesday afternoon through Tuesday evening):
Tuesday will have the highest potential for impactful weather. Conditions may support damaging wind gusts, large hail, and even a low risk for an isolated tornado, depending on how much sunshine develops ahead of the storms.
Heavy rainfall and localized flooding (Tuesday through Wednesday):
Thunderstorms will be capable of producing rainfall rates of 1 to 2 inches per hour. Storms are expected to keep moving, reducing the risk of widespread flash flooding, but localized nuisance flooding of poor drainage areas, low-lying roads, and small streams remains possible. Rainfall totals of 1 to 2 inches are expected, with isolated amounts approaching 3 inches.
Gusty winds outside of thunderstorms:
Southeast winds Tuesday may gust over 20 mph ahead of the approaching storm system before shifting southwest behind the warm front.
Improving conditions late week:
High pressure builds in Thursday through the weekend, bringing sunshine, lower humidity, and several days of quiet, comfortable summer weather.
