No, the word shadow does not have a short a sound. It has a long a sound, as in "sha-doh."
Shadows are long in the evening and morning. They get shorter the higher the sun is in the sky.

The sun is highest at noon, therefore any shadows are short. When the sun is low, at sunrise and sunset, the shadows will be long.

The shadow of the tree would be shortest at midday when the sun is directly overhead. This is because the angle of the sunlight is most perpendicular to the tree, resulting in a shorter shadow. At sunrise and sunset, the angle of the sunlight is lower, creating longer shadows.
At midday your shadow will be at its shortest as the sun is closer to being overhead and you block less of its light. As the afternoon progresses and it gets further past midday the sun sinks lower in the sky and your shadow gets longer.
A shadow is usually longer in the morning and shorter in the afternoon.
The shortest shadow on a sundial would be afternoon or Middaay

shorter
At the winter solstice, the shadow cast by the midday sun is longer than on any other day of the year, and at the summer solstice, it is as short as it ever gets.
Midday because the sun is right above you.
A shadow.
That largely depends on whether or not the sun is up. If the sun is still out a 9pm, a shadow is much longer, then.
