Heavy rain is hitting Nassau and Suffolk Counties and the National Weather Service has forecast that the rainfall will continue through Searly Monday with possible flooding. The flood watch remains in effect Monday morning's commute, according to the weather service. The heavy rain and flooding along with strong winds have caused power outages in our area. Local roads are also closed due to fallen trees and down power lines. Get more information on our weather page.

The jetstream has aligned itself in a zonal pattern across the northern United States. That means it is lined up in a west to east fashion and the result is a very fast moving weather pattern. There are several areas of low pressure that will affect Long Island over the next 5 days making it an active weather week.

A developing low pressure system in the Gulf Of Mexico will move up the East Coast on Wednesday bringing a wind-swept rain to Long Island. The storm has been brewing in the Gulf over the past several days and has gathered plenty of tropical moisture. The available moisture will result in locally heavy rain across all of Long Island, especially Wednesday afternoon and Wednesday evening. 2"-3" of rain will be possible with up to 4" falling in some areas.

It seems lately on Long Island that when we see rainy weather, it lasts for days. This has certainly been the case since the end of summer because of a blocking pattern in the atmosphere. This blocking pattern does not allow much east to west motion of weather systems causing us to sit under the same weather systems for long stretches of time. The past week or so, we lucked out under the nice part of the blocking pattern with high pressure. Sunny skies, comfortably cool nights, and warm days all made for a classic run of fall weather.

Several lines of strong thunderstorms affected Long Island today. The first band hit eastern Suffolk County with torrential downpours and high wind gusts during the early afternoon. That line of storms caused localized flash flooding across the east end. The second line of storms moved in along a cold front just in time for the evening rush hour. That line of storms wreaked havoc on the evening rush by causing flooding that snarled traffic on the LIE and Grand Central Parkway. A lightning strike also knocked out LIRR service between Penn Station and Jamaica.

A large ridge in the jetstream is allowing unusually warm air northward into Long Island. Today, Islip tied a record high of 79 degrees. But not only was it warm, but it was humid as well. The humidity made it feel more like the low to mid 80's, especially across the north shore. The one side effect to the humid conditions will be dense fog in spots tonight, so watch out for low visibility late tonight and early tomorrow morning. And if you like the warm weather, you are in luck. Expect a similar day on Tuesday with highs in the upper 70's.

Humidity increased quite a bit today across Long Island as a southerly breeze took over. Dewpoints climbed through the 60's and are hovering near the 70 degree mark, which is a very uncomfortable level. With the humidity in place and a slow-moving cold front heading our way, scattered thunderstorms will be possible over the next 24 to 36 hours. Most of the storms today have been confined to areas just north and west of Long Island. But as we move through the evening a few storms will be possible.

We are kicking the weekend off in fine style across Long Island this Friday evening. The weather is picture perfect with clear skies, light winds, low humidity, and comfortably mild temperatures. We'll enjoy another comfortably cool night tonight as temperatures will fall into the 50's in many areas.
Saturday will be gorgeous again with sunny skies and high temperatures in the mid 80's during the afternoon. Humidity will increase, so it will certainly feel warmer than it has over the past 48 hours. But overall, Saturday will be the best day of the weekend for outdoor plans.

We enjoyed a great day across Long Island with sunny skies and low humidity. A refreshing northwesterly wind added to the comfortable feel of the day. Heading into tonight, we will enjoy one of the coolest nights we have had in quite some time. Low temperatures will be in the 50's across most of Long Island. Friday will be another great day with sunny skies, low humidity, and highs in the low 80's. The weekend will feature increasing humidity, so get out and enjoy the wonderful weather on Friday!
