Another lovely spring-like Saturday has come and gone. Temperatures reached the 60s with a good deal of sunshine late in the day. It's hard to believe that Long Island will see a pattern change and a shift to more winter-like temperatures next week. Along with the cold snap comes a chance for snow by Tuesday.

A cold front is expected to pass through Long Island through the night Saturday night, leaving the mild temperatures to start the weekend as a distant memory. MacArthur Airport reached a high of 63 degrees Saturday, while some Island locations reached the 50s.

A colder airmass makes its way to the region starting Sunday. With normal highs close to 50 this time of year, highs on Sunday may only return to about 40 during the daytime. A quick moving storm system passes well south of Long Island, keeping the area under mostly cloudy skies. Monday is the first peak of the cold with highs only in the mid 30s and a little sun. Winds stay pretty gusty throughout this time period.

A storm forms off the southeast U.S. coast early Tuesday and heads northeast, gently hugging the shoreline a few hundreds miles out to sea. It deepens into what some meteorologists call a "bomb" or a "monster" by Tuesday night off Montauk Point. While its center passes well offshore, the strengthening storm expands and spits precipitation over the area on its "west" or "left" side. This precip hits Long Island Tuesday night into early Wednesday.

With the cold airmass in place, it's all snow. The actual storm track offshore provides for higher chances of heavy snow for the East End as opposed to New York City. Snowfall numbers should become more accurate starting Sunday. The proximity of the storm track raises other concerns like gusty winds, coastal flooding, and beach erosion.
