For some reason they take the initial measurements in Celcius and then report the inter-hour ones as the nearest Fahrenheit value. So sometimes the real value is higher and sometimes it's lower. Really pretty dumb and unnecessarily confusing.
With SE flow this is just perfect for storm lovers. Always fun to see these storms pop to the south and move over the lowlands.

Downstream (to the northeast of the approaching mid-level low),
forcing for ascent is generally forecast to contribute to
considerable thunderstorm development Tuesday afternoon into Tuesday
evening. Forecast soundings indicate that CAPE may remain limited
to 500-1000 J/kg or less, but beneath 30-70 kt southerly flow in the
500-300 mb layer, strong deep-layer shear will be at least
conditionally supportive of isolated supercells posing a risk to
produce severe hail and locally strong surface gusts.
