IWX favoring the foreign solutions early on.
Friday through Monday...
Some lake effect is likely to linger into Friday, possibly briefly
shifting into NW Indiana for a period until the low level ridge axis
finally passes through Friday night in response to the next area of
low pressure taking shape. While models remain in agreement on a
baroclinic zone establishing itself across the area over the
weekend, timing and ptype issues persist, leading to an uncertain
forecast for those likely travelling home from the holiday weekend.
EC/GEM brings in precipitation during the day Sat with temp profiles
cold enough for all snow through Sat night before shifting east. GFS
delays precip till at least Sunday and maybe not till Monday, which
would suggest more of a mix to possibly all rain. The current
forecast leans towards the faster solution at this time with likely
pops Sat/Sat night. As would be expected this far out, confidence in
finer details is not overly high but worth watching.
