No it was cold at all elevations but has started to go inverted this morning.
Pretty wild profile right now, they are losing it at this moment. Wet bulbs are punching upper 20s now. It was low to mid 20s most of the night.
Quad top... 36F wet bulb of 26F (only 15% RH, very dry aloft above the inversion).
Mid-Mtn... 32F with wet bulb of 28F.
Base... 34F with wet bulb of 29F.
