Pressure and weather in Yonkers
Yonkers rises steeply from the east bank of the Hudson opposite the Palisades, immediately north of the Bronx, with the river on one side and the hills of southern Westchester behind. The Hudson is a genuine weather feature here rather than scenery: the valley channels wind along its axis, and the tidal river moderates temperatures near the water enough that riverside neighbourhoods stay a degree or two warmer than the higher ground inland during a winter storm — often enough to change snow to rain within the city limits. Nor'easters running up the coast between December and March are the dominant pressure events, and the deepest of them can move the barometer thirty millibars or more in under twenty-four hours. Late summer brings the tail end of tropical systems curving north, which produce the year's fastest falls, and the dense urban fabric adds a strong heat island effect on still summer nights.
What this means for you
Coastal storms and tropical remnants give the lower Hudson Valley two very different kinds of steep pressure fall each year. Watching the current barometric pressure through both seasons will tell you whether rate of change or absolute low matters more in your case.
