Liqui Moly has one as does Castrol it seems.
LM and Castrol are both much heavier A3/B4 oil grades.
In an OTC 0W-30 there is only one in the States and that's M1 AFE 0W-30. And in your PA climate, as has been mentioned there are 5W-30s that are likely as light on start-up. Three examples would be Pennzoil Ultra, Havoline and Formula Shell.
Of course if you engine has been back spec'd for 5W-20 then a 0W-20 would be the way to go.
