What to Expect

It's a beautiful start to summer and Father's Day across the Hudson Valley. Today features less wind than yesterday and plenty of sunshine to start; however, a few midday clouds are expected and a brief shower is possible. Marine conditions are better today. No weather-related advisories are posted for boaters or swimmers today.

Rain is likely on Monday with showers expected for much of the afternoon and heavy downpours possible. This could produce localized flooding with some neighborhoods seeing 1-2" of rain. Showers may linger through Tuesday morning.

Conditions improve Tuesday afternoon, with several days of dry, comfortable weather returning before another chance for showers arrives late Thursday into Friday.

Today: Nice for dad

Sunny skies are expected with less wind. Clouds will thicken later in the day, but the risk for rain is low. Temperatures are in the low 80s. There is a low risk for rip currents and sea conditions will be better for boating with wind speeds generally SW at 10 mph.

Monday: Heavy rain is possible

Mostly cloudy skies are expected in the morning, with showers possible to start. Heavy rain will develop for the afternoon. A half inch of rain is likely but isolated spots of 1-2" are possible in thunderstorms.

Tuesday: Early morning showers, then clearing out

Showers are likely in the morning but will taper off later in the day with mostly cloudy skies. High temperatures are near 80-degrees.

Rest of the week: Seasonable summer weather

Drier weather and less humidity returns by Wednesday. A few stray storms are possible at the end of the week, but it does not look like a washout. High temperatures will be in the 80s, with overnight lows in the 60s.
