Weekend Downpours Present High Water Risk
In a summer known for its lack of heat and an abundance of quick hitting thunderstorms, the weekend ahead will play true to form; namely, moderate temperatures and a few tropical downpours.
Thursday’s warm sun and low humidity values gave way to a late day hazy sky. Pullman Square concert goers and County Fair midway walkers were treated to a very pleasant night for socializing.
But the haze and cloud cover of the evening is the first sign of an important weather change. Rain clouds are already moving toward Valhalla and the PGA golf tourney in Louisville late Thursday night and those showers and downpours will spread into Central Kentucky along I-75 by Friday dawn.
Those initial showers will likely arrive in Eastern Kentucky before noon then into Southern Ohio and West Virginia on Friday afternoon. Localized downpours can back up some storm drains and a few lightning strikes can flicker the power grid in the late afternoon.
Friday night concerts (Live on Levee, Pinch Reunion, county fairs) will still be at risk for a shower as fog forms in the humid air just after dark.
However by Saturday the heavens will be primed for new downpours as the risk of street flooding returns.
It remains to be seen if the rains fall hard enough to support small stream flooding.
Saturday outdoor events will be rain challenged with likely 3-5 hours of daytime rain and the constant specter of showers.
Sunday’s air will not be as moist, but with breaks to sun exciting the moist air, a shower or thunderstorm is likely in most areas, once or twice.
