Long Island: Black Ice, Heavy Snow Squalls, and Zero Degree Wind Chill Temperatures
See the "My Personal Weatherman" Facebook page for frequent updates.
- From the National Weather Service: "As precipitation comes to an end across the region in the next few hours concerns are for areas of black ice to develop as temperatures fall below the freezing mark this evening and tonight. Temperatures are expected to remain below freezing through the Wednesday morning commute... The main concern is the potential for snow squalls in the afternoon and early evening, potentially corresponding with the evening rush. Both the NAM and GFS remain bullish on the snow squall parameter, with the upper low barreling towards the area from Canada supporting the conceptual model. Scattered heavy snow showers have been included in the forecast. Otherwise, the first half of the day will be dry, and the arctic front will usher in windy and cold weather for Wednesday night. Winds gusting to around 35-40 mph." - The 1st image shows the projected wind chill temperatures from the NAM for 3 AM Thursday. I have included the simulated radar from the NAM for 6 PM tomorrow to give you an idea of the hit-or-miss nature and general timing of the snow squalls.
