Mid-level dry air
Similar to
goal post sounding but with more moisture (higher
precipitable water in sounding)
The dry air aloft will entrain into the
downdraft and cause
evaporative cooling. This increases
the negative buoyancy and can result in microbursts and macrobursts
If supercells develop they are most likely to be high precipitation supercells
Most common severe weather:
winds > 58mph, small hail near the 3/4" threshold, tornadoes possible
(depends on low level shear
and CAPE)
Sounding most commonly found east of Rockies
