Winter? ;-)

No, positioning of upper air features/jet trajectories, changes in
stability, cloud distribution, proximity/arrival of drier air,
modifying of slow moving air, origins of air masses.....of course
winter makes it cooler, but with respect to average winter
temperatures, air cools differently if it has a strong SSW Tropical
origin than it would with a slow or moderate Polar or Polar
Continental origin.

Go and read basic meteorology texts about airmass theory and
modification of airmasses in different seasons. Then read up about
upper air theory and the broad scale distribution and propagation of
jet streams and upper atmospheric thermodynamics.
It is all very interesting, we are talking real weather here, not
climate.
