The winds will rise over the mountains. If the air is unstable, the air will continue to rise, forming cumuliform cloud on the windward side with rain or snow.
If the air is stable, cumuliform could could still form but the air sinks down the lee side of the mountain and then rises and falls again establishing a series of waves downwind from the mountain. The tops of these waves are often marked by lenticular cloud.
If the cloud on the windward side has produced rain or snow, the air descending on the lee side warms more rapidly than it cooled rising on the windward side. This warm wind is known as the foehn or chinook

The winds will rise over the mountain, becoming cooler and losing moisture in the process. Usually, that produces rain or snow on the side facing into the wind.
As the air mass then falls over the top, it is much cooler, and if the air on the other side is significantly warmer, then there will be cold, brisk winds entering all the canyons and channels on the other side.
As warm air rises over a mountain, clouds are formed which can veil the mountaintop.
Mountains can be a truly miserable place if you are unprepared. A good day on a sunny mountain can change to tragedy with a mere shift of wind and weather.
There was such a tragedy out west recently, I believe it was Mt. Shasta, about four people died.
Airplane pilots and mountaineers should be REQUIRED to learn about weather hazards appropriate for their occupations.
Air also moves faster through various impediments, given a constant pressure behind the air mass. I think that is called the Bernouili effect (my spelling not always perfect). That means the winds are generally much FASTER on a mountain and in canyons, often ferocious.
Sometimes the winds are so ferocious they will freeze you fast or maybe even blow you and your tent clean off of the mountain.
If there is lots of powdery snow around (or even packed snow, if the winds are fast enough), lots of wind can produce a total WHITEOUT, so that you cannot possibly see where you are going, cannot see a person connected by rope a short distance ahead, maybe not even your hand in front of your face.
At least 98% of women are definitely not mountaineers, and the men will have to carry them out if they go.
The percentage is pretty high for men, too.
An inexperienced group may never return, so never go unless more than half of your group is experienced.
Train on small mountains first.
The tops of some mountains, such as in Guatemala, have a curious feature: You can go a distance of 12 feet and leave a wet area having vegetation, also raining cats and dogs, and on the other side everything will be barren and arid. To a similar or lesser degree, one often sees this on other mountains and mountain ranges.

When strong winds hit mountains, they reduce velocity because they are dispersed in several direction. For examplle, a typhoon generating a wind velocity of 200 kph in the ocean would hit land at only 140 to 160 kph because it passes through mountain ranges that reduces its velocity. For the mountains, of course the winds break or uproot some trees and could cause flashflood and soil erosion if the winds are part of a storm associated with heavy downpours.

Precipitation can happen. Orthographic precipitation to be more specific. (That's precipitation that happens at mountain ranges.)
