Good Wednesday morning! We're starting off the day with a little patchy fog in a few spots across Long Island, but otherwise, we're looking at another beautiful day of weather. Once the morning fog clears, expect mostly sunny skies with a few passing clouds and temperatures climbing close to 70 degrees this afternoon. That's well above our normal high for early November, which is in the upper 50s. It will be a warm, dry and comfortable afternoon, perfect for getting outside, taking a walk, enjoying the fall foliage or getting some outdoor work done. After nearly two weeks of dry weather, though, some changes are on the way as we head toward the end of the week.

Long Island Today forecast

For tonight, clouds will gradually increase as our next weather system approaches the region. It will remain dry overnight, with temperatures dropping into the 50s by early Thursday morning. Thursday will feature plenty of clouds, although we could see a few breaks of sunshine early in the day. A few spotty showers may develop during the afternoon, but it won't be raining all day. Temperatures will remain unusually mild for November, with highs in the upper 60s to lower 70s. If you have outdoor plans Thursday afternoon, keep an umbrella handy, especially later in the day.

Long Island tomorrow forecast

Our weather turns wetter Thursday night as showers become more widespread across Long Island. Skies will remain cloudy, with overnight temperatures settling into the 50s. Friday is shaping up to be the wettest day of the week as a storm system and cold front move through the region. Expect periods of rain, with some moderate to locally heavy downpours possible, especially during the morning hours. We can't rule out a few thunderstorms during the day, either. Right now, we're watching the potential for 1 to 2 inches of rainfall, a

llthough the exact amounts will depend on the track and timing of the storm system and cold front. After nearly two weeks of dry conditions, this rainfall could be beneficial, but heavier downpours may also produce ponding on roads and reduced visibility for drivers. Friday's temperatures will remain mild, generally in the 60s to around 70 degrees. If you're traveling during the morning or afternoon commute, allow some extra time and be prepared for wet roads.

Heading into the weekend, we may still have a few leftover showers around Saturday morning as the storm system slowly moves away from Long Island. However, the good news is that conditions should improve as we go throughout the day, with clouds giving way to increasing sunshine during the afternoon. It will be a little breezy at times, with high temperatures reaching the 60s. If you have outdoor sporting events, fall festivals or other activities planned for Saturday, the afternoon is looking like the better time to be outside. Just keep in mind that some fields and grassy areas could still be wet or muddy following Friday's rainfall. Saturday won't be a complete washout, and we should see some nice improvements as the day goes along.

Sunday is shaping up to be a beautiful November day across Long Island, with plenty of sunshine, dry weather and high temperatures near 60 degrees. It will be a great day for outdoor activities, whether you're heading to a sporting event, taking a walk, enjoying the fall foliage or catching up on some yard work. You'll probably want a light jacket or sweatshirt during the cooler morning hours, but the afternoon should feel comfortable in the sunshine. Overall, the weekend is looking better as it goes along, with a few lingering showers Saturday morning followed by a brighter afternoon and a dry, sunny Sunday. The main weather concern remains Friday's potential for heavy rainfall, so we'll continue watching the storm track and rainfall totals closely. In the meantime, enjoy today's beautiful, warm November weather before our next round of rain arrives!
