You shouldn't, they almost certainly will favor the non-Euro models. At this point the Euro's just about on its own, along with its ensembles. The GEM is somewhat of a compromise of the north and south models, but nothing looks favorable for Milwaukee and Madison pretty much but the Euro.
If nothing else, maybe this can be one of those elusive thunderstorms to wintry precip/snow transitions. Doesn't happen often, but with how dynamic this storm is, could happen.
I doubt severe here, but if you've been monitoring the hi-res and local RPM models, still seems like a squall line might pack a punch tomorrow evening from Chicagoland up to nearly Lake Winnebago.
Money is in line to get a garden variety storm or two this evening. We weren't really even expecting precip here or nearby until yesterday's forecast, so a thunderstorm or two would be a nice entrance into spring weather.
