In the Grip of Cold and Snow

In the Grip of Cold and Snow:
October 18-22, 2020 will be noted in the history books of Minnesota as one of the coldest and snowiest 5-day periods in October.

Despite an abundance of cloud cover over this period, temperatures have been exceptionally cold for this time of year, running from 12 to 18 degrees F below normal, especially daytime highs. On the 20th of October this week Orr, MN reported the coldest temperature in the nation with a reading of 9°F.

But the widespread significant snowfall has captured most of the media and public attention, starting a very early snow shoveling and snowplowing season. Several new daily snowfall records were set at long-term climate stations by the storm over October 20-21 including:

Sunday Night Soaker

Sunday Night Soaker:

That rainfall came Sunday night over October 11-12. Over a hundred of the state’s climate stations reported a rainfall between 1-2 inches, mostly coming at night. Portions of Washington, Dakota, Rice, Nicollet, Blue Earth, Pine, and Kandiyohi Counties received over 2 inches. For many long term climate stations new record daily rainfall amounts were reported, including:
Hastings 1.90”
Cloquet 1.88”
Milaca 1.80”
Lakefield 1.45”
Floodwood 1.44”
Windom 1.12”
Winnebago and Jordan 1.43”
Long Prair[e 1.29”

Portions of western Minnesota were left out of this beneficial rainfall and only reported less than a tenth of an inch.
