Weather synopsys: Sunday January 30



(Click Image To Enlarge)
5:35pm a major winter storm is brewing promising heavy snow and ice across much of the country including the Northeast from Monday night through Wednesday. This storm system will create thunder snow along with near blizzard conditions in Buffalo on Wednesday morning during the height of this storm with heavy rain and or ice south of the NY/PA boarder including coastal sections of the Northeast and Midatlantic. Initially, snow will break out late on Monday night and will continue through Tuesday - this first round of precipitation will produce a general 3"-6" snow accumulations through the Northeast from Buffalo to Long Island. Then precipitation will begin to tapper off to light snow on Tuesday evening; snow will begin to mix with freezing rain and sleet early morning on Wednesday south of the NY/PA boarder and along the coast. The storm's peak impact on the region will be felt during the morning hours on Wednesday lasting through early afternoon before dissipating late in the evening. Total snow accumulations in Buffalo, NY will likely exceed 15 inches and locally over 20 inches due to the high snowfall rates with this storm - when you factor in wind gust in excess of 30 miles per hour we're looking at a good chance of a bonnafied blizzard in Buffalo during the morning rush. The forecast gets more complicated as you head towards the coast as warm air south of the storm track will mean a variety of precipitation - we could be dealing with a period of significant icing in New York City before the precipitation changes over to rain late Wednesday morning. The exact track this storm will take as it heads east is not set in stone, a deviation to the south will mean less snow in Buffalo and colder temperatures along the coast yielding heavier snow in New York City. Regardless, this storm will have a major impact over the region with massive disruptions and delays possible.
