The temperature reached 56 degrees, eclipsing the former record-high of 55 set in 1931.
That came four days after this area endured wind chills that reached 42 degrees below zero.
Area residents took advantage of the pleasant weather Sunday by taking walks, riding bicycles, washing cars, cleaning out garages and pickup up sticks.
Plenty of dog walking took place as well.
“Went for a walk with my dog and then came home and sat outside while watching the birds,” Karen Wagner wrote on the Reflector’s Facebook page. “It was a great day after the previous few days of frigid weather.”
"Walked our hyper 15-month-old black Lab for 45 minutes, since she’s been cooped up the past five days,” TJ Thomas wrote. “What a gorgeous day!”
“Played with the dogs outside,” Amber Hernandez wrote. “(I) don’t recommend it — just finished washing them and mopping floors.”
Hernandez and other area residents might face extra mopping this week, considering the weather forecast.
Building warmth will be accompanied by soaking rain and locally strong thunderstorms from the southern Plains to the Ohio Valley spanning Wednesday through Thursday.
The same storm set to unleash snow and ice across the North Central states will pump in warm, moist air on its southeastern side.
The warmer weather will mean lower heating costs when compared to last week and the need for fewer layers for anyone stepping outside. Highs will be near-record levels across the Ohio Valley around midweek.
"Heavy rain and thunderstorms will be a concern with this system across the Ohio and mid-Mississippi valleys," said AccuWeather Meteorologist Brandon Buckingham.
The rainfall, along with recent snowmelt, will lead to significant rises on streams and rivers which can cause inundation in low-lying, unprotected locations.
Reduced visibility and a heightened risk of hydroplaning at highway speeds will threaten motorists on stretches of interstates 30, 40, 55, 64, 65, 69, 70, 71 and 75.
Secondary roadways may be closed due to high water.
“Conditions could be right for severe storms to develop, as well,” AccuWeather Meteorologist Faith Eherts said.
Damaging winds, frequent lightning and torrential downpours can accompany the strongest storms. If all of the right ingredients come together, an isolated tornado or two can also occur.
Today, the sun will rise at 7:36:27 a.m. and set at 5:52:31 p.m.
On Wednesday, the sun will rise at 7:35:19 a.m. and set at 5:53:47 p.m.
