A complex of rain and storms is in place across southeastern Indiana and southwestern Ohio. These are moving to the south and southeast. They also, brought some much-needed rain to some locations across eastern Indiana and western Ohio.
A couple of boundaries are visible via surface observations. One is the wind shift across western Indiana, the other is an outflow boundary from the morning convection.
We will be watching both of these areas for some isolated to scattered areas of rain and t’storms to develop this afternoon. The HRRR model shows some of those developing through the day. While it may be a bit aggressive with coverage, I do support the idea of developing precipitation.
Overall rain will be hit and miss once again this afternoon. However, places that get under the rain could see .10-.30”. If a couple of thunderstorms do develop some locally heavier amounts of .60-1.2” or so can’t be ruled out, especially with the high moisture content. (higher precip. around Cincy is from current cluster)
Over the weekend the upper-level ridge will be in place. This will allow hot and humid air to work in with temperatures rising into the 90’s Saturday. Heat Indexes Saturday, and in some locations south on Sunday, will be in the mid 90’s to low 100’s, so if you’re outside make sure to stay hydrated and cool.
By mid to late next week an upper-level trough will build into the forecast area. This will bring slightly cooler weather, but much better chances at rainfall.
The GFS shows some very healthy rainfall through the next 7 days. While the numbers and placement will need fine-tuned, it’s the general change to a more active pattern that I want to show you.
