  • Hoping the cooler weather will bring enough of a cold snap to shut down the 2011 allergy season?
    There might be a bit of a wait.
    The National Weather Service points out that the average first frost in Kansas City is Oct. 28, more than two weeks from now.
    That’s drawing on readings dating back to 1888. Lee’s Summit readings date to 1962 and show an average first frost on Oct. 17.
    The average wait for a hard freeze – 28 or below, when annual plants die and perennials begin to go dormant – is Nov. 6 for Kansas City and Oct. 28 for Lee’s Summit.
    Last year was pretty close to average: The first 32-degree day in Kansas City was Oct. 29, and the first 28-degree day was Nov. 5. The earliest frost so far in this young century was Oct. 6 in 2000, and there was hard freeze the next day. Otherwise, the frost has come no earlier than Oct. 13. The earliest first frost on record is Sept. 22 in 1995, and the latest is Nov. 24 in 1931.
    Also, as fall progresses, the Missouri Department of Conservation points out that the fall colors of the state’s abundant oaks, hickories, maples and ashes usually peak in mid-October.
    It is expected to be cooler this week with a chance of some rain. This morning’s light rain broke a three-week rainless streak. There’s a chance of rain Tuesday evening and Wednesday. Otherwise, the week is forecast to be sunny with highs generally in the 70s and lows in the 50s.
