Seven Day Forecast

Today is going to be mostly sunny and cooler. Many of us will see a cloudy start to the morning, but clouds will decrease throughout the day. High around 55*. Breezy. Northwest wind 15 to 30 mph.

Tonight it will remain mostly clear and chilly. Low near 35*. Definitely one of those "make sure you shut the windows" nights before you fall asleep. Tomorrow looks to be the best day of the week with sunshine and highs in the mid to lower 60's. There is a chance of rain Wednesday through Friday. Much cooler air arrives Friday with temperatures in the 40's and cooler temperatures this weekend.

Have a great day!

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.
