November 12 2020

One extreme often breeds another in the world of weather.  The recent rain event, still underway as I write this report, produced record rain and flooding in and around central Maryland. This was from a cold front and moisture well ahead of Tropical Storm Eta.

This also came after a full week of unusually warm temperatures with two record highs. The purpose of this report is to document them both.

Record Weather Reports

The heavy rain on Veterans Day produced numerous flooding.

If you followed my forecast reports, the NAM 3 Km Model did the best job in this storm. It had looked like it was overestimating the rain, but it was close to on target!

Widespread flooding was reported around Great Mills and along the river.  This peaked within 2 Feet of Record High levels.
