My own predictions -the GOP will take over the Arkansas legislature this year, and will likely continue to narrow the gap in the Kentucky House while shoring up their majority in the Kentucky Senate. This is a conservative prediction, mind you -it is entirely possible that the GOP can take over the Kentucky legislature outright, and thus be in position to redistrict the state chambers next year.
As for West Virginia -there is no chance in hell that the GOP can take over this year (needless to say), but they will gain substantially in the legislature there in both chambers much like their counterparts in Arkansas did in 2010 who faced similar daunting odds that year.
I will not comment on the other states, except that the outlook does not look bright for Democrats anywhere in the region -especially in North Carolina.
If Republcians were going to take over the Kentucky House, 2010 would have been the year. Same with West Virginia. Not every year is going to be 2010 for Republicans.
Not everything moves exactly in tandem with the national climate. (In fact, this is probably the biggest mistake people make with respect to downballot predictions).
