Friday: Rain Moving In

It's going to be a very very rainy night tonight - and we may have some showers linger into Halloween.

Here's the setup: We have warm air advecting into the Tri-State today. That warm air will send our temperatures soaring to the lower 70s. Middle 70s should be off to our south, but nonetheless it will be a warm day.

The upper trough over the Plains won't move in until tonight, and that means the rains won't become steady until tonight, either. There will be what we call "Warm Air Advection showers" this afternoon, as the warm air rises, moisture condenses and cools and that should produce rain showers.

Tonight, in comes the front. That will bring rain both pre- and post-frontal. The post-frontal rains will be extended due to lift, which will be enough for 1-2" of rain across the Cincinnati Tri-State area tonight.

After this, I expect rain to end west to east on Saturday. There have been some indications that rain showers may linger into Halloween Night - but I am not buying into them, and I'm keeping Halloween Night dry for the trick-or-treaters.

Past that, models want to bring a shortwave trough through Northwest Ohio Monday. I don't think Cincinnati sees anything from this - so I'm keeping the forecast dry from Saturday night, through next week.
