Last Monday was the first time in 222 days that there were no flood
warnings in Illinois, according to Dan Smith, regional coordinator
for the Illinois Emergency Management Agency. The past week's
weather has been one of the best in memory.
As late as Saturday, the 10-day weather model showed temperatures
as high as 98 degrees for the weekend. Fortunately the latest
National Weather Service model shows temps going back into a normal
August range of 85-88 degrees by the end of the week.
Unfortunately, this drop in forecasted temperatures is due to an
upper-level trough that will bring a cold front into the area late
on Thursday or early on Friday. This convection can cause rain in
our area Friday, Saturday and Sunday.
The chance of precipitation for Friday is 20 percent, with a 30
percent chance of showers on Saturday and a 50 percent chance of
rain on Sunday. The National Weather Service does not believe any of
the rains will be heavy, but they could put a damper on festivities.
Because of the weather pattern activity, there is a chance that
the forecast will change again, and possibly the rain will be
minimal this weekend. But the chances of a completely dry art and
balloon fest are not promising at the time of this report.
LDN will keep you up to date on the weekend's weather with the
latest information as it is received.
