Not sure about MDT but I think York, Lancaster....southern LSV....get near 60. No where near the upper 60's the Euro had but I think it beats lower 50's as well.
Edit-I should add why I think it gets near 60 in the southern LSV. It is already in the 60's in SW PA and up to near Martinsburg, WV. If the "CAD" gives way in the LSV I think it sky rockets quickly. Could be totally wrong LOL but there is no cold air coming to temper the jump if it happens re: S/W PA.
