No. An updraft (updraught) is an upward moving current of warm air.
polar creep
No. Usually, when warm air moves against a stationarymass of cold air, the warm air will gently move over the colder air and a light, long lasting rain shower will take place. If a moving mass of cold air violently shoves warmer air upward, then the rains are usually more intense.
It is a Cold Current.

Tornadoes usually weaken if cold or dry air starts feeding into the updraft of the thunderstorm that drives the tornado. This causes the updraft, and thus the tornado, to lose power.

The canary current is a cold current.
Tornadoes get their energy from the rotating updraft of their parent thunderstorm. If cold or dry air gets into the updraft it will weaken it (warm, moist air rises more easily), causing the tornado to dissipate.
Hail is formed when a thundercloud has a strong updraft, a lot of water, and a large cloud layer with below freezing temperatures. The updraft takes the water up through the cold cloud layer causing it to freeze into hailstones.
Tornadoes often weaken as a result of cold or dry air entering the updraft of their parent storm.
It is generally thought that tornadoes dissipate when cold air chokes off the thunderstorm updraft that powers them.
How a tornado ends is not fully understood. It is thought, however, that cold air coming out of a thunderstorm (called outflow) undercuts the mesocyclone, the rotating updraft that drives the tornado. This chokes off the supply of warm air that feeds the updraft.
