Chicago's recent round of beautiful weather with unlimited visibilities and cool
temperatures -- among them the coolest highs in five weeks -- have seen overnight
lows as chilly as 49 degrees in far west suburban Rochelle and 51 degrees at nearby
DeKalb. Normal lows this time of the year are in the low 60s. As cool as those Chicago
area readings have been, minimum temperature in recent days across the North Woods
of Wisconsin have dipped to truly autumn-like levels, including 40 degrees at Ashland,
41 degrees at Merrill and 43 degrees at Superior and Antigo. The cool readings are the
product of northwest steering winds that have guided Canadian air across the Midwest.
Thunderstorms on the west side of this cool air pummeled sections of Nebraska on
Monday. They towered to 51,000 feet and unleashed nearly 5 inches of rain on Butte --
on the Nebraska/South Dakota border.
WEATHER BEING MONITORED IN THE ATLANTIC COULD BE TROPICAL TROUBLE
Two areas of disturbed weather are being monitored by tropical weather forecasters at
the National Hurricane Center. Either or both may develop into tropical depressions in
the next day or two.
