NWS Wilmington OH

[9:14 AM] Warming temperatures and dry conditions this Memorial Day.

Dense fog advisory until 9am for Mercer, Auglaize, and Hardin Counties in Ohio.

Widespread dense fog is developing near and east of Interstate 75 early this morning. Visibility will begin to improve by around 9 AM.

[10:30 PM] A special weather statement for patchy dense fog has been issued. The close proximity of the cold front + very saturated soils is resulting in some early fog development. Will continue to monitor trends.

A county flood warning was issued for Hocking given numerous road closures and high water issues. Several other counties in the Scioto Valley and Northern KY continue to deal with high water issues and road closures. Be careful, especially as we head into the overnight hours.

[4:53 PM] Several rivers/creeks continue to overflow their banks with the renewed rainfall today. A handful of river points are still expected to remain in flood stage overnight. Remember that water.noaa.gov is great site to track the latest river observations/forecasts.

312pm: Showers and isolated thunderstorms continue to move across the region this afternoon. They will continue into the evening before tapering off overnight. Some of the rain will be heavy at times. Do not drive into flood waters!

[2:15 PM] Flash Flood Warning for Bracken, Mason, and Robertson Counties, KY until 5:15 PM.

10:20am: Rain is moving into the area from the south. Rain will continue to overspread the area today. Rain may be heavy at times. This will also keep temperatures cool today with high temperatures in the 70s expected.

It will gradually get warmer through the rest of the holiday weekend. There will be more showers and storms about the region today, but then drier on Monday with any chance of rain limited to along and south of the Ohio River.

More showers will develop today along with some thunderstorms. The environment is still favorable for some of these showers and storms to produce locally heavy rainfall. This could lead to some flooding issues mainly south and east of I-71.

Rain builds back in near the Ohio River near daybreak Sunday, expanding northward. An additional 1-2+ inches of rain is certainly possible, especially for locations along/SE of I-71. Isolated flooding issues are possible again, in addition to any ongoing river/creek flooding.

10:30am: In addition to the flood threat, there is also the potential for some strong to severe storms today in central Ohio. Remain aware of the weather today.

With all the recent heavy rainfall and additional rainfall expected in the coming days, it is important to remember to never drive around barricades and never drive through flood waters. Some water may remain on roadways for a long period of time after the rain has stopped.

Rainfall amounts the past 24 hours. 2 to over 3.5 inches of rain in spots. Some flood advisories and river flood warnings are in effect. Flood watch out for part of the area for additional thunderstorms today.

Locally heavy rainfall will still be a possibility this afternoon from central Ohio into northeast Kentucky with strengthening showers and some thunderstorms ahead of a weak cold front. Therefore, there continues to be the potential of flash flooding in those areas.
