Background: Cumulative rainfall in the upper Pecatonica River basin through mid to late September:

Plot of cumulative rainfall in inches at three Wisconet stations. Althree show a steep rise on Sept 18-19, with a little more gradual increase to between 4 and 6 inches total by Sept 21. Curves are then flat until yesterday and today.

On the flip side of the rain is the drought. We've seen a slight expansion in Exceptional Drought on this week's Drought Monitor, and a broader expansion of extreme drought across northern Wisconsin.

Wet morning in southern Wisconsin, with many of our stations reporting more than an inch of rain since midnight. If you've got your wipers on - make sure you've got your headlights on! It'll help other drivers see you.

We'd certainly like to see more rain than this across northern Wisconsin, but we'll take every drop we can get to try and alleviate some of the drought conditions. New drought monitor comes out tomorrow morning.

Here comes the rain again...but it's once again missing the extreme and exceptional drought in northern Wisconsin. Expansion of the extreme and exceptional drought areas seems likely.

Stop us if you‘ve heard this one before: We’re dealing with dense fog this morning across northern and northwestern Wisconsin. We’re in the middle of Wisconsin fog season, so pay attention to where the main foggy areas are - because they’ll likely be like that for the next couple months.

It’s a tale of two halves of the state. The west side is mild, the east side is cool. Still dealing with a little fog in the eastern half of Wisconsin, so keep that in mind as you’re out and about this morning.

Break out the flannel…we’ve got low-40s all the way to the Cheddar Curtain. And with near 100% relative humidity and calm winds this morning, there may be patchy areas of fog, so take it easy on the roads if you’re headed out to the apple orchard for some fresh cider donuts.

Another couple freezes last night, with Fence dropping to 28°. Frosty across much of northern Wisconsin this morning. It’s a little warmer here in Stevens Point, where we’re at the Wisconsin Emergency Management Association for the next couple days.

With the rain coming to an end, here’s a look at how much we’ve measured across Wisconsin in the last 72 hours. The highest totals have been in southern Wisconsin, where a few of our stations have reported more than 4 inches.

We’ve picked up quite a bit of rain in southern Wisconsin in the last 24 hours, with Soldiers Grove leading the way at more than 4“ so far. Heavy rain events also help us identify rain gauges that might be having some issues - like Porter, which appears to have a clog.

Tomorrow has been upgraded to a Level 3/4 risk for flash flooding by the Weather Prediction Center. These are fairly rare. We only see these about once or twice a year in Wisconsin. The heaviest rain concerns are over far southern Wisconsin tomorrow. Don't drive through flooded roads!

A wet weekend for southern Wisconsin - with many places expected to receive 2-4" of rain, especially along and south of I-94. A Flood Watch is in effect for southwestern Wisconsin tonight through tomorrow at 1 pm. Watch for flooding in low-lying areas. Turn around, don't drown!

Parts of southern Wisconsin could see 2-3 inches of rain this week, with some areas seeing more rain than they've seen in the past month! Unfortunately for the extreme drought area, the rain totals are looking lower, with up to an inch possible. We'll take what we can get.

We may see some storms develop across northern Wisconsin tonight along and ahead of a cold front moving out of Minnesota. The strongest storms may produce gusty winds and hail. A Level 2/5 risk of severe weather is in place for extreme northwestern Wisconsin. Not expecting much rain, unfortunately.

We've seen some improvement to the Drought Monitor this week (mainly over east-central Wisconsin, where we saw 2-5" of rain last week!).

32% of Wisconsin is abnormally dry, 18% is in moderate drought, 27% is in severe drought, and 15% is in extreme drought.

Well that's a ton of birds. 103 million plus. They were mainly flying 1500-2000' above ground and in the dark, so if you're wondering why you may have not seen them, that helps explain it.

Pretty damp start to Tuesday, which is a good thing because we've been needing the moisture. It also fits the vibe of the first day back after the holiday weekend.

As we were mentioning yesterday, our drought conditions may lead to lower quality fall colors this year.

With ongoing drought and warm conditions expected to persist this fall, there are concerns that our fall colors could be less impressive and long-lasting than normal. Are you already seeing colors in the trees?

It looks like fall out there, with a lot of low clouds and goldenrods popping everywhere, but it doesn’t necessarily feel like fall, with high dewpoints still throughout the state. Still waiting for that fall cold front to come through and really bring us into the season.
