Hot start to week with pleasant air arriving for holiday

Sean Ash

Our latest round of splash-and-dashers will continue to push east into Ohio and set much of central Indiana up for a relatively dry evening. Dry in the precipitation sense, but the Muggy Meter remains sky high and oppressive with dew points in the 70s.


As a result of the sticky air, air conditioners will continue to work overtime tonight into Monday. Highs tomorrow will near or go above 90 degrees. We’ve yet to hit that magical number this season thanks in large part to the wet June and abundant soil moisture that’s lead to high levels of evapotranspiration (humid air heats and cools slower than dry air).


Much of Monday will be dry, but we’ll need to monitor a complex of severe storms in Illinois late tomorrow for local impact.


Western and northwestern Indiana (including Lafayette and Peru) are under a Slight Risk for severe weather…primarily for late tomorrow. But this is highly conditional on how long the aforementioned complex will hold together, and where it will track. At this point I’m not overly optimistic this feature will have a high impact on the viewing area.


It should be noted one potential outcome is for this feature to weaken before impacting the viewing area and the convective boundary setting south of the region Tuesday. This would mean most would miss out on rain and storms. It’s too early for a high level confidence on any given output though.


However, we feel confident on a pleasant set up for the 4th of July thanks to a seasonably strong Canadian high pressure system. You should notice a big difference in the air mass Wednesday, despite warm highs in the 80s. Thursday and the 4th of July are about as good as it gets for July…with comfortable humidity and highs in the 70s! The pleasant air should linger into the weekend though the air mass will modify and allow highs to get back into the 80s.


Have a nice evening – Sean Ash
