Hi Paul,
It sounds like an optical effect: see Wikipedia under 'Mirages, Superior M=
irage=92, which echoes/explains your grandfather=92s observations. Extrac=
t:
"A superior mirage occurs when the air below the line of sight is colder th=
an the air above it. This unusual arrangement is called a temperature inver=
sion<https://en.wikipedia.org/wiki/Temperature_inversion>, since warm air a=
bove cold air is the opposite of the normal temperature gradient of the atm=
osphere. Passing through the temperature inversion, the light rays are bent=
down, and so the image appears above the true object, hence the name super=
ior. Superior mirages are in general less common than inferior mirages, but=
, when they do occur, they tend to be more stable, as cold air has no tende=
ncy to move up and warm air has no tendency to move down.
Superior mirages are quite common in polar regions<https://en.wikipedia.org=
/wiki/Polar_region>, especially over large sheets of ice that have a unifor=
m low temperature. Superior mirages also occur at more moderate latitudes, =
although in those cases they are weaker and tend to be less smooth and stab=
le. For example, a distant shoreline may appear to tower and look higher (a=
nd, thus, perhaps closer) than it really is."

Hi All
In the old days before blizzards of weather forecasts
the appearance of the size of the land in the distance
was considered a sure weather indicator.
"The land is looming up - must be a storm coming!" my Grandfather
would say.
If from home the mountains or hills if you wish of Pictou
and Antigonish Counties could be easily seen most days
If they appeared low - fine weather - if 2 or 3 times normal height
a storm was brewing. Today as I drove along Western Shore the islands
of Tancock and Ironbound along with the smaller ones all appeared
2 to 3 times their usual size. Probably a storm on the way.
Is that a common oldtime weather indicator in other places?
Enjoy the storm
Paul
