Cold Front

Earlier this week, an exceptionally potent cold front blasted through the region, and brought colder and windier conditions with it. Marathon Airport broke their record daily low temperature by 4 degrees fahrenheit. and multiple automated observation sites reported wind gusts just above 40 mph. There are a lot of observations that we continue to sort through, but we wanted to share some highlights that we have readily available. The record daily low was set on Tuesday, November 11th at Marathon Airport when it recorded 55 degrees. The previous record was 59 degrees set in 1953 and 1956. The record cool high was also set the same day at Marathon Airport when the high only reached 64 degrees. The previous record cool high was 66 degrees set in 1956. The strongest wind gust we have observed so far is at the Key West buoy when it reported a 44 mph gust, or 38 knots. The Key West Buoy is courtesy of the National Ocean Service Water Level Observation Network.
