The first weekend of fall is certainly looking like it with plenty of cloud cover and seasonable temperatures so far. We'll add some rain back in for Sunday.
Normally if we are talking about rainfall amounts in a storm of 0.5-1" that is not a big deal at all. We wouldn't be concerned in the slightest about flooding or road hazards. But, given the current situation with already very saturated ground we will once again be worried about flooding through Sunday.
A large upper trough out in the western U.S. will be sliding east, pushing this Plains system through our area to end the weekend. This will be a cold front with showers and some storms, rainfall amounts shouldn't be that much, but still enough to lead to areas of flash flooding. This has prompted the National Weather Service to issue Flash Flood Watches for most of the area. There are still many river flood warnings also in effect.

If you do have outdoor plans for Sunday it will be wise to have the rain gear ready. Temperatures should be able to get back into the low 70s but there will still be wet weather in the forecast. For the parade and festivities in Warrens for the Cranberry Festival it will be wise to pack the rain gear and the same is true if you are headed over to Green Bay! The most widespread rain looks to fall early in the day with some scattered showers through the afternoon and evening. Again, not much in the rain gauge but enough to cause issues with flooding. It will also be increasingly breezy with winds shifting to a more westerly direction.
The early part of next week will then turn decidedly cooler for a few days as the big upper trough slides east, into the Upper Midwest. In addition to cooler air, it will bring some clouds and shower chances. Forecast models seem to be in agreement that most of these will move through in about a 24 hour period, with the most noticeable impacts on Monday. The day will also come with some strong winds, along with a mix of clouds and sun. Scattered showers will be around, with highs only in the lower 60s making it one of the coolest days we've seen in a while. The fall-like feel will carry into Tuesday, but as this trough slides east, any shower chances exit. Tuesday will start to see a bit more sunshine with highs again in the 60s. The second half of the week should warm up again as the jet stream lifts back north. High pressure will be taking hold, bringing some beautiful early fall weather to the area. Wednesday through Friday currently look to feature quite a bit of sunshine and temperatures rising back to above normal levels. So, hang in there...there is light (literally!) at the end of this tunnel (forecast)!
Have a great rest of the weekend!
