I think that is the crux of the difference between some of the models. Nam and Icon are both finished up or close to it by that point vs. the wide swath of precip on the Euro.
Icon on TT does not show sleet or FRZ but the temp profiles look pretty bad with the low getting up to the M/D. Mid to upper 50's heading toward the Trainer Thursday night. 18Z RGEM is not winter precip at all for the LSV.
NO time to look at specific but GFS holds on. Mostly holds its own....NAM, Icon, are basically little to no winter weather in the LSV. Rgem sneaks some frz in at the end but not to the level of the GFS.
