Long Island will remain mild today and tonight, with temperatures feeling more like early spring than winter. That changes quickly on Thursday as a cold front moves through. Rain showers today will taper off overnight, and as colder air rushes in Thursday, temperatures will drop during the day instead of rising. While areas well north and west of the city may see a light coating of snow, Long Island is expected to stay mostly rain with little to no snow accumulation. By Thursday night into Friday, it will feel much colder than earlier in the week, with temperatures returning to more typical winter levels. Wind will be a major factor for Long Island late this week. Thursday and Friday will be windy, with frequent gusts between 25 and 35 mph, making it feel much colder than the thermometer shows. Wind chills could drop into the single digits late Thursday night into early Friday morning. Looking ahead to the weekend and early next week, a few weak weather systems may pass nearby, bringing a small chance of light rain or snow, but nothing heavy or widespread is expected. The bigger story will be the cold: temperatures trend downward through the weekend, with below-average highs by Sunday and even colder air settling in early next week.
