MIDWEST — Drier air will filter in from north to south today, though it may not make it south of I-70 until later on. Dewpoints will drop into the lower 60s across the northern half of the region this afternoon, marking a nice change of pace from the muggy conditions that have persisted recently.
Northern Areas See Comfortable Drop in Humidity by 5 PM
Model data valid for 5 p.m. today shows dewpoints falling into the 50s and lower 60s across the northern portion of the region, a noticeable improvement in comfort levels compared to recent days. This drier air mass is pushing south, gradually easing the muggy conditions that have dominated the pattern.
The transition zone sits roughly along and north of the I-70 corridor, where dewpoints are expected to drop into a more comfortable range by late afternoon.
Muggy Conditions Persist South of I-70
South of I-70, dewpoints remain elevated in the upper 60s to low 70s, keeping conditions feeling sticky and humid through the afternoon. This area has yet to see the drier air mass arrive, meaning residents south of the transition zone should expect the muggy pattern to continue a bit longer.
Progress Expected as Drier Air Continues Pushing South
Forecasters note that while the drier air hasn’t yet reached areas south of I-70, its arrival represents real progress in breaking the recent humid stretch. As the drier air mass continues advancing southward through the day and into tonight, more of the region should begin to feel the more comfortable conditions already in place farther north.
