Seven Day Forecast

Tonight the clouds will continue to roll in. Low near 25*, with an east wind at 10-20 mph. Light snow will develop into the morning. Some areas could see accumulations of less than an inch, with higher amounts further to the southeast towards the Twin Cities. High of 36* with a east wind becoming northeast at 20-30 mph.

The rest of this week should remain mostly dry. However on Saturday there is a chance to see some rain showers. Highs will return to mild conditions. Warmer air will surge in for the weekend. Expect highs this weekend back into the 60's, and could continue into next week.

Differences Between the new and old systems

  • Wind speed is now calculated for 5 feet off the ground. Wind speed was previously based on observations at 33 feet.
  • The calm wind threshold was lowered to 3mph.
  • A consistent standard for skin tissue resistance is now in use.
  • Measurements are based on how wind affects the human face, typically the most exposed portion of the body.
  • The table incorporates the theory that heat is lost from the body depending on its surroundings
  • The sun's impact is not factored into the wind chill temperature formula.
