With the issuing of WSW's for Chicago and the N IN lake effect belts, I figured that this event has become thread-worthy. The main storm system isn't that notable, with the warm ground leading to at most an inch or two of accumulation for some higher terrain areas away from the lake. However, after the main system passes through we could have a significant lake effect event for so early in the year, especially on Sunday night into Monday. LOT and IWX have highlighted for the potential of at least several inches of snow wherever a main band sets up for any length of time. Combined with wind and the fact that leaves are still on the trees from the previously very warm autumn, this could be a potentially significant early-season event. Especially considering the possibility that one of the bands may set up into downtown Chicago and points south of the city, and the fact that this really has only become a thing within the last 24 hours.

Fortunately there are several indications that we are about to end up in a much more active pattern potentially starting next week. And with a still well-above average Gulf, could get interesting here for storms. The fact that, unless something stupid happens, we are going to have a Gulf like that with no TCs to cool it down before storm season kicks up is going to make things interesting for moisture availability the next couple months imo.

Yeah no complaints about the forecast for the next week. Consistent upper 60s and sunny, the perfect October combo. Much better than the June in October weather of last week. And with a hint of a more active storm pattern incoming for the second half of the month for those who are going to go "but it's so boring!"

I guess we are doing June in October again. This could be forecast for the week of Father's Day or the 4th. Not so much for October 1st. At least the days are nice though. Just to think, we have the same daylight as ~March 10th rn, where we can have a foot of snow on the ground and 20 degree highs.

Drought monitor is starting to look pretty rough to the S and E of the forum. Widespread D1 with pockets of D2 and even an area of D3 (!) in OH and S IL.

The next week+ looks like almost an exact repeat of last September's consecutive 80s streak, with maybe just slightly less intensity. Will be interesting to see how many consecutive 80s we have, which after today's date is more and more impressive the later we get into the month. And how much we recover the anomalies for the month. We bottomed out around -9 a couple days ago, so we'll see if we get close to or above average for anomalies after this stretch.

Looks to be a very cool start to the month for the entire region. Some very impressive cold anomalies showing up for later next week considering the time of year and how far out this is. Definitely a difference from the last couple of Septembers where we were in the 80s and 90s well into the month.

Woah, I did not realize it has been that dry down there this month.

Yeah I'd be alright with this weather for the next 6 weeks, with the occasional rain chance so we don't dry out.

It's been a couple years since we have had our late August first cool wave. Definitely will feel nice (smoke not withstanding) after this humid summer.

Yeah MKX is really highlighting the potential for multiple rounds of rainfall pretty much every night from tonight through Tuesday next week, depending on where the mesoscale boundaries and such line up. This could get interesting fast around here, as thanks to last weeks rain we can't really tank a couple inches of rain again. And anything E of the Rock would be a huge concern given all the flooding in Milwaukee and fact that the rivers have mostly just fallen out of flood stage. These types of events with a stationary boundary sitting across the state have really hurt in the past (2018,2007). Hopefully it will not be to that level at all, but considering what happened lsat week I'm not all that confident to say the least.

It is going to be a long night for S WI for rain/flooding. Already a rare FFW out for Milwaukee and West Allis (On State Fair weekend no less!) with 2.5"+ hrly totals. And WPC just put out a pretty strongly worded MPD for the area.

Yeah I'm definitely worried for some potentially significant flooding somewhere in S or SW WI. While it hasn't been as wet as most of IA over the last 30 days, it's still been wet enough to cause concerns even without some of the more extreme totals that models have put out. SW to NE is a bad direction for precip maxes in regards to the drainage network in this part of the state. And 6-10 inches of rain in a night would be very bad news for really any drainage around here.

It always amazes me how much of a difference there is for # of 90s pretty much every year between Chicago and Madison. Madison is only at 8 for 90s so far this year. Obviously the UHI is a major part of that, but still such a stark difference over only ~85 miles in latitude.

Huh, I did not realize the SPC outlook for 8/18/05 looked like that. Crazy it has been 20 years since then. I was too young to remember it personally though. I can't and frankly don't even want to imagine what it will be like when we get another Stoughton or Oakfield level tornado in the Madison area, and we have had a couple close call setups where that would have been possible the last few years.
