STORM WATCH: THURSDAY P.M.

While we are not expecting severe weather or widespread flooding on Long Island thankfully, Thursday will just be a day to have the rain gear and use caution traveling. Showers will develop mostly after 2 p.m. Thursday with a round of steady, at times heavy rain through the first half of Thursday night. A thunderstorm also cannot be ruled out. Travel can be slowed Thursday evening from times of moderate to heavy rain and visibility will be low in any scattered downpours.

Rain totals through late Thursday night look to be around one-inch or a little less but can exceed one-inch where heavier downpours occur. Highest amounts will be in Nassau and western Suffolk Counties, with lower totals likely in eastern Suffolk County. Scattered ponding of water is possible. Scattered periods of rain can linger into early Friday morning.

FUTURECAST

Here is a look at the latest future radar for Long Island showing the timing of the rain that arrives on Thursday.

MULTIPLE RAIN CHANCES AHEAD

Beyond Thursday, Friday through the weekend still look unsettled with off and on rain chances. There will be some breaks at times but expect a hit or miss shower or two on Friday with more clouds than sun at times. The timing of any steady weekend rain will become clearer through Thursday, but plan on scattered off and on rain showers on Saturday and Sunday for now. At this moment, it looks like a steady round of rain will be likely midday on Saturday, tapering off in the evening. It should be a drier start to Sunday, but scattered rain chances will increase into the afternoon.

BOAT AND BEACH

Anyone heading to the beach should check the latest rip current statements before getting in the water. Check out more of the local beach weather forecast and tides here.
