WEDNESDAY OCTOBER 18 - FALL FOLIAGE - PART I
It's a rite of passage of autumn. The leaves put on a show of color. This short-lived
display of fall foliage is a natural response to the decreasing amounts of sunlight
that accompany the slide into winter.
Weather plays a lead role in just how colorful the foliage will be. Warm, sunny
days and cool but not freezing nights are ideal for producing the most spectacular
colors. Lots of cloudy days and warm nights leads to a more drab display. And an
early frost or heavy wind or rainstorm could quickly end the show.
There's not a whole lot of year-to-year variation in the peak foliage time for a
particular location. But there is a north to south variation in the peak time
because you lose sunlight hours a little more quickly the farther north you go.
Thus the peak time ranges from mid-October in the Lehigh Valley to early November
in central and southern Delaware and southern New Jersey.
