The Deluge Has Ended

After nearly 4.5″ of rain in parts of southeastern Connecticut the heavy rain has come to an end. Here’s a look at some of the rain totals across the state – many of which are quite impressive!

  • Westbrook – 4.71″
  • Norwich – 4.46″
  • North Haven – 3.49″
  • Bridgeport (ASOS) – 3.15″
  • North Grosvenordale – 3.12″
  • Hampton – 3.08″
  • West Hartford – 2.22″
  • New Hartford – 2.06″


The rain was focused along a warm front that managed to sneak into southern Connecticut. The winds were out of the south and east in Groton, Westerly, and Westhampton Beach while Providence, Willimantic, and New Haven had northerly winds. An impressive theta-e gradient as well with mid 50s for temperatures and dew points in Groton and low 40s elsewhere in Connecticut.

The Yantic River managed to reach moderate flood stage with 4.5″ of rain through the basin while other rivers in northeastern Connecticut reached minor flooding benchmarks.



Not a surprise to see minor flooding given the setup with a strong low level jet on top of a stalled warm front near the south coast. A nice surge of high precipitable water air moved in overnight all in a region of strong quasi-geostrophic ascent and even a bit of elevated instability. Classic “sultan of sandbag” signal for southeastern Connecticut, Rhode Island, and southeastern Massachusetts.
