Southern Ohio residents can expect a continuation of hot weather today as clear skies dominate the region. The National Weather Service reports that a mid-level ridge is shifting eastward, and a tight pressure gradient will bring forth southerly winds reaching up to 20 to 25 mph in gusts. "Warm temperatures to continue with highs in the mid and upper 70s Tuesday," a forecast discussion from the National Weather Service indicated, noting that these readings are about 10 to 15 degrees above normal.
Moving into tonight, while keeping temperatures milder than recent nights, mainly high-level clouds are expected to form, with a southerly breeze maintained. Lows are predicted to be in the lower and middle 50s, considerably warmer than the past few nights. Winds will continue to carry a breath of warmth from the south at 7 to 10 mph.
A dry cold front will move through the area on Wednesday, bringing a temporary increase in cloud coverage but no moisture significant enough to result in rainfall. After the frontal passage, "southwest winds 10 to 20 mph will shift to the northwest with gusts up to 25 mph," according to the National Weather Service. The temperatures, however, will remain on the warmer side before the front, with highs ranging from the lower 70s northwest to the upper 70s southeast.
Looking ahead, a quick-moving trough is forecasted to usher in near seasonal temperatures on Thursday, soon after being replaced by a narrow ridge on Friday that will lead to another warmup in daytime temperatures. The forecast, including some uncertainty, suggests a chance of rainfall on Friday afternoon into the early night, primarily to the north towards Central Ohio. According to the National Weather Service's long-term forecast, "Temperatures drop for the weekend to near or just below seasonal normals" as the region transitions into drier conditions.
VFR conditions are expected for aviators today and into the evening, with some high clouds in the mix. However, as stated by NWS, aviators should be aware of potential low-level wind shear developing overnight due to a 40 kt 925 MB jet moving into the area. The forecast anticipates no significant weather post-Tuesday, which should offer clear conditions for aviation operations.
