If you look at a barometer you will see that hot weather almost
invariably comes
with high (not low) air pressure.
It is just the opposite here in the far north. High pressure areas
produce clear skies here, but the high air pressure is due to the
cold of the high pressure area, which often originates in the north
over land or ice. The clear skies don't provide enough solar energy
to make things hot and therefore humid overcast and cool, except in
summer when the skies are clear in the morning during high pressures
but cumulus clouds and cooling showers can form in the late
afternoon. Low pressure often involves being in the center of humid
low pressure cyclonic winds, often originating over the oceans, and
which bring warming weather, in the winter warming back up to near
freezing, bringing overcast, clouds and snow.
