IMPROVING WEATHER

Strong storms generally stayed west of Long Island this evening and the chance for strong storms is now over for the evening. A few showers and a very brief downpour cannot be ruled out, but that's it for the rest of tonight.
Overnight, clouds and a few showers will be possible and Thursday morning will be our next chance for any heavy rain and thunderstorms after this evening.

FUTURECAST

Here is a look at the hour-by-hour weather conditions projected for Long Island through midweek.

EXTENDED FORECAST

TONIGHT: STORM WATCH -- Mainly cloudy, with the chance for scattered showers and a few strong-to-severe thunderstorms through mid-evening. Not all of Long Island will get strong storms. In fact, the chance appears to be a bit more isolated as of Tuesday evening's forecast. That said, strong wind, downpours, frequent lightning, hail and a low risk for a tornado remain possible until that scattered storm threat ends. Use caution while traveling if bad weather hits where you are. The chance for any pop-up stronger thunderstorms will diminish after 8 p.m. or 9 p.m. Then, expect a mainly cloudy sky overnight, with some patchy fog and spotty light rain or drizzle from time to time. Lows in the 60s into Wednesday morning. Wind: east-northeast 5 to 15 mph.
WEDNESDAY: A changeable weather day, with a mostly cloudy and the chance for a couple of passing rain showers. Breaks of sun possible. Highs around low to mid-70s. Lows near 66.
THURSDAY: STORM WATCH -- A round of showers and thunderstorms in the morning. Then, partly sunny in the afternoon, with a pop-up shower or storm chance. It will not be a washout of an afternoon, but a brief heavy drenching thunderstorm will be possible. Highs around 83. Lows near 67.
FRIDAY: Mostly sunny to partly cloudy. Highs around 82. Lows near 64.
SATURDAY: Sun and clouds. Highs around 76. Lows near 60.
SUNDAY: Sun and clouds. Highs around 75. Lows near 60.
MONDAY: LABOR DAY -- Sun and clouds. Highs around 76. Lows near 60.
