climate for the northeast region of the united states
Northeastern United States The climate of the Northeastern United States varies from northernmost New England in Maine to southernmost New Jersey and Pennsylvania. The climate of the region is created by the position of the general west to east flow of weather in the middle latitudes that much of the central and northern USA is controlled by. Summers are normally warm in northern areas to hot in southern areas, while in winter the subtropical high Bermuda High retreats eastward, and the prevailing westerly flow of air masses combines with the polar jet stream to bring cold and frequent storm systems to the region.[52] Annual mean temperatures range from the low 50s F from northern Maryland to southern Connecticut, to the 40s F in most of New York State, New England, and northern Pennsylvania.[52][53][54]
