YORKTOWN, N.Y.-Yorktown residents awoke Sunday, Feb. 18, to see 7 inches of snow on the ground.

Three days later, all of the snow had melted and residents were having visions of summer as record-high temperatures washed over the area.

At 79 degrees, Wednesday, Feb. 21, was the hottest February day on record in Yorktown, according to climate historian Dr. Jerome Thaler. The previous record was 74 degrees, which was set last year.

Thaler and his son, Daniel, have been documenting weather events in Yorktown for a half-century. In 1964, Thaler started as a “Cooperative Observer” for the National Weather Service by setting up a station at his Yorktown Heights home. Today, Daniel maintains a weather station in Shrub Oak.
