A warm and comfortable Monday is ahead for Aurora. Although temperatures will be very warm, the humidity should lower enough to give the area a break from the tropical conditions that have dominated the month.
A cold front pushed through the area on Sunday night. The front will lead to more of a dewpoint change than a temperature change. A Canadian high pressure with drier air will push in behind the front.
With a mostly sunny day, temperatures should warm into the upper 80’s. Early morning dewpoints will still be in the upper 60’s but should come down to the lower 60’s during the afternoon. The heat index should also be in the upper 80’s, making the air feel much more comfortable.
The break from heat and humidity will be short lived. Temperatures are likely to again reach the upper 80’s on Tuesday. The high pressure will move off to the east, allowing the humidity to creep higher.
Early indications are that the heat will build back north, bringing a warm front back into the area for the second half of the week. This is the same pattern that the area was under over the weekend. Temperatures around 90 degrees and very high levels of moisture could lead to waves of showers and thunderstorms with heavy rainfall.
The National Weather Service warns that warns that some rivers are near flood stage, including the Fox River, from heavy weekend rains. Never try to cross a flooded roadway.
