Peoria, Ill. – Dangerous heat and humidity plagued Central Illinois late last week as temperatures soared into the 90s with heat index values between 110° and 115°. This extreme heat led to the death of one person in Peoria over the weekend.
A Canadian high-pressure system has settled over the Central Plains and the Midwest bringing a welcomed change to the weather pattern to the region. With high-pressure to the west, northerly winds have brought in cooler and drier air to Central Illinois. This area of high pressure is expected to remain over the region through much of the week keeping the region dry and comfortable throughout the week.
While temperatures will gradually warm throughout the week, they will remain near to below average through Thursday. During this time, dew points are expected to remain in the 50s and 60s resulting in rather comfortable weather across the region. It will also give us an opportunity to turn the AC off and open some windows at night.
By the weekend, temperatures will climb back into the upper 80s and 90s with dew points returning to the lower 70s. While this will bring back some uncomfortable heat and humidity, it won’t be as oppressive as the heat we saw last week.
Even though the weather is great this week, we look to return to a warmer and wetter pattern early next week.
