The National Weather Service in Wilmington, Ohio, has issued a Dense Fog Advisory, effective until 8:00 AM EST this morning, for parts of Ohio and Kentucky, enveloping the Ohio Valley in a blanket of low visibility. Motorists in affected regions, including Ohio's counties such as Mason and Bracken, and Kentucky locales stretching from Boone to Lewis, are advised to exercise caution due to reduced visibility that could potentially drop to less than a quarter mile in some areas, according to the National Weather Service.
In addition to the foggy start, conditions are set to change throughout the day with high pressure bringing mostly sunny skies, a welcome departure from the grey, as winds from the southwest drive up temperatures to the upper 50s; however, the warmth comes at the cost of strong gusts that are expected to be more noticeable than not with wind speeds picking up between 10-20 mph and gusts possibly reaching 30-35 mph—a sharp contrast to the near-stagnant air embroidered by this morning's fog.
Looking ahead, Ohio will witness a slight reprieve in temperature, with clear skies and calm winds allowing lows to fall to the low and mid-30s by daybreak. By Tuesday, however, Ohioans will be facing a different climate story as the high-pressure camped to the south facilitates a return flow that heralds warmer nights and days, pushing low temperatures into the 40s Tuesday night. High temperatures, reaching the mid to upper 60s, are expected on Wednesday as the low-level jet stream carries moisture ahead of an approaching cold front.
As the week progresses, the region is bracing for diverse weather phenomena. High pressure is expected to set the stage on Thursday with a more temperate climate, only to give way to another front by Friday, which is not likely to come through dry, foreshadowing rain ahead of a noticeable chill for the weekend. By Sunday, the mercury is forecast to dip even further, with daytime highs varying from the mid-40s in northern areas to the lower 50s in southern Ohio and northern Kentucky, leaving the night waltzing in with the possibility of lows teetering on the upper 20s to near 30 degrees, set to be the coldest readings of the forecast period.
