Snow piled up rapidly in parts of the northeastern United States on Tuesday as a blizzard began blowing in, with residents being advised to stay at home, airlines grounding flights and schools canceling classes. It scaled back those predictions on Tuesday for places such as New York City, which was due to get between 4 and 8 inches (10 and 20 cm).
Even more flights are expected to be canceled on Tuesday, when Upstate New York and other areas along the East Coast are expected to get hit with heavy snowfall.
Most of Wednesday's cancellations are morning flights. His office also warned that the Metropolitan Transportation Authority, which operates the subways in New York City, could limit or cancel rail service entirely, depending on how severe the storm is.
A high number of flights have also been cancelled at smaller regional airports, like T.F. Green in Providence, Manchester-Boston Regional in New Hampshire, and Portland International Jetport in Maine.
While South Florida temperatures won't be drastically affected by the winter blast - temperatures are expected to drop by Tuesday night - the airports were definitely impacted Monday.
The flight cancellations included more than 2,800 in the New York City area alone, where about 200 passengers were stranded at Kennedy Airport.
In Massachusetts, where the forecast called for 12 to 18 inches of snow, Gov. Charlie Baker encouraged motorists to stay off the roads and to take public transit only if absolutely necessary, saying the fast snowfall rates would make driving hazardous. "It's obviously going to be the biggest event we've had this season and people need to be prepared".
Preparations continued Monday across the Northeast for the arrival of what forecasters say will be the first major winter storm of the season, bringing with it dire warnings of blizzard conditions in New Jersey, New York and CT.

Fears over the expected ferocity of the storm led to the first meeting between US President Donald Trump and German Chancellor Angela Merkel in Washington being delayed until Friday.
Philadelphia and New York City got anywhere from a few inches of snow to around half a foot before it switched over to sleet.
