Looking forward to a wetter Sept here in the N sub, Going through my modelling method, Early Sept looks to have a rather stubborn SE ridge with LP's moving across the N. A boundary may hang out across the S sub during this time. As we move into the 2nd week, I'm expecting that ridge to breakdown, and we should start to see much cooler wx start to arrive, especially by mid month. The 2nd half of the month looks like a rollercoaster in the jet. End of the month happened to catch my eye as a very significant storm may develop in the W sub. We'll see how this works out. Definitely need good rains up here, and I think Sept will deliver.

On the bright side we might get some epic LES this winter if the lakes stay warm during cold snaps 

Great point you bring up there. Wouldn't hate some LES hits and possible svr chances (depending on how warm the warmth surges are) this winter

I recently pulled the seasonal stats for Chicago during past strong and super El Niño episodes. Dating back to 1950, there have been seven seasons that have featured an El Niño of strong to super magnitude. To shed a full light on the situation, I pulled stats both met winter (DJF) and the full October–April snowfall season.

The clearest signal is snowfall. Every one of the seven strong/super El Niño seasons featured below normal snowfall during both the DJF and October–April periods. In several of those seasons, snowfall was significantly below average.

When it comes to precip, it's more of a mixed signal. Both the DJF and October–April periods feature a mix of very wet, near-average and dry seasons.

Temps lean warmer, particularly during met winter. DJF temps ranged from slightly below normal to well above normal, with warmer outcomes more common. During the longer span October–April periods there is more variability, with most seasons within +/- 1° of average, while a couple were well above average.
