Figure 1. Minimum temperatures for DEOS stations throughout Delaware for November 19, 2014.

Temperatures around the First State were more like January than November this morning. In fact, several official National Weather Service observing stations reported record low temperatures:

  • Wilmington New Castle County Airport: 19 degrees (Previous record: 22 in 1997)
  • Dover Air Force Base: 21 degrees (Previous record: 24 in 1959)
  • Georgetown Sussex County Airport: 19 degrees (Previous record: 24 in 2005)

Typical low temperatures for November 19th range from 36 to 38 degrees across Delaware, but today’s temperatures were nearly 20 degrees below normal in some parts of the state. Around the Delaware Environmental Observing System network, temperatures were in some cases even lower. Below is a list of stations that saw low temperatures dip below 20 degrees this morning:

The current cold weather pattern we are in is unusual, but not unprecedented. The lowest recorded temperatures in Delaware on this date occurred in 1936 at several locations up and down the state, with Wilmington Porter Reservoir coming in the lowest at 15 degrees on November 19, 1936. Temperatures are expected to remain unseasonably cold for the remainder of the week, with signs of a milder weather pattern coming early next week.
