Answer:
A blizzard can form when warm air combines with a high pressure system.
Explanation:
A high pressure zone is defined by cold air mass that has higher density than surrounding air mass. Therefore when a warm air current blows towards the high pressure system, the warm air mass rises over the cold air mass of the high pressure system.
The warm air begins to cool at the front between the cold air mass and warm air mass. Usually for a blizzard to occur the cold air mass is usually below freezing point temperatures. Therefore the moisture in the warm air cools and freezes into snowflakes. This is why the winds of a blizzard are accompanied by snowflakes akin to a winter storm.
