Seven Day Forecast

Good Morning! With clear skies and light winds this morning, temperatures are certainly on the chilly side. We'll see a lot of sunshine today, and it will be a bit warmer. High near 42*, with a north wind at 5-10 mph. A few clouds will move in through tonight, but overall, it sky will be clear. Low near 28*, with a northeast wind at 0-10 mph.

Clouds will be on the increase Friday, and it will be windy as well. Rain will develop over western North Dakota, and will spread into our area during the night. Drier conditions move in for Saturday, with temperatures warming into the 60s. Highs will remain in the 60s to near 70 through the middle of next week. A storm system will move in for Wednesday, and will bring showers and thunderstorms to the area, along with slightly cooler air.

Have a great Thursday!

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.
