I think an Advisory is prudent for the entire CWA and depending on how the band looks in the AM, that’s where a warning gets triggered.

I think 3-6” is a lock for the entirety of Cook County. The higher amounts will be in the northwestern part of the county and some lucky spots on the lake where LES is most persistent.

Not bad

Extremely disappointing performance from the American guidance.

Yea I think the 18z euro is pretty much a best case scenario with this type of set up, that is, lacking any more prominent synoptic features.

Assuming the Euro doesn’t cave, shaping up to be US vs foreign models. Fun.

Ouch

This seems like one of the rare occasions this early in the season where the lake shore can outperform the burbs. I think the timing of the front is key for the metro area as the more precipitation we can maximize outside of peak daylight hours, the more significant accumulations can be. Temps are certainly not as marginal as the last event.
