Showers Tomorrow - How Much & When? Plus, More On That Cool Weekend

It's a busy day on the KDLT Weather Blog. You probably read Cody's post introducing you to a cool weekend ahead... and tonight we talk more about the rain coming and how that will eventually lead to a chilly weekend.

First off - after some more lighter/scattered showers & thunderstorms tonight to the West and to the East by tomorrow morning, we are looking for the main threat of rain and thunderstorms to move in late Tuesday night into early Wednesday:

You can see the showers there by 12:30am - at least according to our new Futurecast computer model. Add or subtract an hour or two from that time, and that is about when you can expect showers and thunderstorms. It seems as though this storm system will slow down and leave us with some decent amounts of accumulations:

That up to 1 inch mark is basically centered around the Mitchell area - but has the potential to shift around a little bit. In general we are looking for most people to pick up around a quarter of an inch, with locally heavier areas picking up closer to 1" of rainfall.

Then we have the chilly weekend. You saw some first glimpses of the cooler air overhead for the weekend in Cody's post below, but look at this image showing possible morning lows for this weekend:

Middle 40s are becoming a little bit too common, but that is a sign of things to come - unfortunately. Our average overnight low for southeastern South Dakota dropped to 51 today, and will continue to drop for a while.

Enjoy the rest of your Labor Day holiday and have a good rest of your week!
