Quiet behind Henri

Tropical Depression Henri is stalled out over southeastern New York, keeping the chance for a few showers in our forecast today.

Henri has weakened considerably from its time over land. The primary area of rain associated with Henri is a small area of moderate rain in the Hudson Valley area. By this afternoon, Henri should begin to pull away to the east.

There are a few scattered showers over the far eastern and far western Finger Lakes this morning associated with outer bands of influence from Henri. These showers are light and brief and will not cause any issues this morning.

As the daytime heating kicks in, isolated to scattered showers will pop up this afternoon, moving from north to south on the fringe of the circulation of Henri. A few of these may linger into the early evening before skies clear as Henri departs.

A few localized downpours will be possible from the afternoon activity, but any downpours will be brief and should not cause any flooding issues. The one exception may be Cortland County, where even a brief downpour could cause some localized minor flooding. A flash flood watch is in effect for Cortland County as a result.

Sunshine will gradually increase today as well, and highs will be around or slightly above 80 degrees.

Clear skies overnight will allow temperatures to slip back into the mid 60s tonight. River valley fog will be possible but should burn off quickly Tuesday morning. Tuesday will turn out mostly sunny with just a few stray clouds. Highs will be a couple degrees warmer than today with many areas in the mid 80s.

Wednesday, too, will be quiet and dry. Fair weather clouds will develop for the afternoon, but no rain is expected. It will be the hottest day of the week with highs topping out around 90 degrees. Dewpoints will continue to be in the 65-70 degree range, so heat index values will be several degrees above the actual temperature.

Unsettled to End the Week

The weather will become more unsettled late in the week as a couple of weather systems move through the region.

First will be a cold front Wednesday night or early Thursday. Showers will first become possible Wednesday evening with an increasing chance for rain after midnight. Showers and a few thunderstorms will continue into Thursday morning before ending by the afternoon.

There is still a bit of uncertainty with the timing of the front, which could result in a shift in the main rainy period further into Thursday. Neither severe weather nor excessive rainfall is expected.

Temperatures behind this front will not drop too far, with highs in the mid 80s Thursday and Friday. Friday looks to be dry at this point with a mix of sun and clouds.

Scattered showers and storms look possible both Saturday and Sunday, though it is too early to nail down the details. It will remain warm and muggy, with highs held to the low 80s by the potential showers and storms.

Unsettled conditions may persist into Monday or even Tuesday before a front sweeps away the heat and humidity. The first days of September look dry and cooler, with highs in the 70s and lower humidity.

    Hi Drew,
    I read your reliable forecast everyday and tell folks why, too. I am already a paid subscriber.
    I am also a painter and wonder if you took today’s photo? And which lake it is and what are the far hills? If this photo is one of your I’d like permission to paint it.
    Thank you.

      Hi Susan! The photo is not mine but I can get in touch with the photographer to see if she would be OK with that and to get you the location information!

      Thanks so much for your support!
