Winter Storm Warnings for Suffolk and Winter Storm Watch for Nassau for tomorrow (Thursday). The most recent NAM run is showing potential for huge snowfall amounts for all of Long Island. The official NWS forecast is calling for 6 to 12 inches for Suffolk and 5 to 8 inches for Nassau. If the new NAM is right, amounts could increase to 12 to 18 inches. Wind gusts over 40 mph will create blizzard conditions. The GFS is showing 6 to 10 inch amounts, and the Euro is showing 4 to 6 inch amounts. The NAM does a very good job with winter storms inside of 72 hours. More data will be gathered this morning and fed into the models, which should help the models converge on a solution by tonight. A 50 mile shift in track means all the difference. Snow should begin on Long Island between 1 AM and 4 AM and end between 6 PM and 10 PM Thursday. Also, accumulating snow will take place in every state along the east coast from Florida to Maine with this storm, an extremely rare event. Expect school closings tomorrow and, if the blizzard scenario unfolds, Friday as well. Extremely dangerous wind chills Friday into Saturday with 30 mph wind gusts. Temps near zero Friday night and close to -5 on Saturday night.
