After a chilly night with some patchy shallow fog that may be dense in bottomland areas, around rivers, lakes, creeks, 76-80 highs will occur tomorrow. High/mid clouds will increase tomorrow PM as a warm front edges closer, but the humidity will still be low.
A wave of some cool rain & the potential of isolated thunder looks to pass Friday morning as the warm front approaches, followed by a mostly cloudy to cloudy sky in the afternoon with only an isolated shower or two. Rainfall coverage will drop from 65% morning-early afternoon to 15-20% beyond that. Highs will only run near 70 to the mid 70s from east to west after 50s to 60 in the morning.
Warm front will continue to lift northward Friday night.
A few storms are possible late in the night to Saturday morning with the front.
As the front continue to move north & eastward, check out the high humidity overspreading area behind it! Dew points may reach the widespread mid 70s by later Saturday & be just as high Sunday! So, I "upped" wording from "humid" to "very humid". If dew points reach or exceed 75 over a good chunk of the viewing area for many hours, then I attach the "very" to "humid".
Strong southerly to southwesterly winds will also bring oppressive nights in the 70s. However, the breezes will help cut the heat some. Even with upper 90s to lower 100s heat indices a breeze in your face makes it a little easier to take.
Some more scattered storms are possible just south of & along the warm front in our viewing area Saturday afternoon-evening, as well as Sunday to Monday. However, coverage will tend to decrease with time with 45% dropping to 35% Sunday & 30% Monday.
Severe weather risk will largely be confined northwest & north of our area where better wind fields & shear will exist. An isolated severe storm or two could occur Saturday to Monday, otherwise, it looks like garden-variety summer storms.
We will monitor.
Tuesday looks completely dry area-wide.
Storms are possible Thursday-Thursday evening (August 29). This is the evening of the Purdue-Northwestern football game at Ross-Ade, so eyes will be on future rounds of data coming in to see if storms affect its start time at 8 p.m. Notice another wave of storms in Iowa moving southeastward that may end up affecting the area next Saturday (September 1) after a drier Friday (August 31).
