Residents across the Midwest, prepare for a cool and dry weekend courtesy of a stubborn high-pressure system hanging around the Great Lakes. That's the forecast narrative laid out early this morning by the National Weather Service. Local temperatures are expected to stay a few degrees shy of the norm, keeping daytime highs floating between 75 and 80 degrees. If you're in Columbus, Cincinnati, or any adjacent areas, consider this an opportunity to enjoy the outdoors without the typical summer swelter.
Intriguingly, a weak inverted trough is set to sneak into the upper Ohio Valley tonight, potentially bringing showers to southern regions by Sunday. It’s looking like a moistening trend that could interrupt the dry spell, so those living near the southern periphery better stay weather-aware. As explained in the forecast discussion from the National Weather Service, "Lows tonight will be in the mid 50s to lower 60s with highs on Sunday in the upper 70s to lower 80s."
Turning our gaze to the week ahead, the lazy upper trough from the west is expected to fizzle out by Wednesday, after which the region looks to be settling into a pattern of dry and steadily warming conditions. Rain chances are slim—hovering around 20% up until mid-week—mostly confined to Kentucky and near the Indiana/Ohio border, according to the long-term forecast reflections by Franks.
And for the aviators out there, you're in for smooth sailing. The same NWS forecast indicates that, beyond the possible development of some fair-weather cumulus clouds this afternoon and high-level ones drifting through, conditions look clear. That being said, watch out for some potential MVFR visibility restrictions due to river valley fog towards dawn, particularly at KLUK. The outlook otherwise leans towards the expectation of no significant weather disruptions for the next several days.
