Radar does not scan for cloud patterns.
In the case of finding a tornado it looks at wind speed.
If a winds are moving very fast towards the radar and winds moving fast awaay from it in a small area, it means strong rotation and a possible tornado.
A a radar is better: it can detect a tornado at a distance. A barometer would be of no use unless the tornado came dangerously close.
Satellites equipped with cameras and sensors are commonly used to observe cloud patterns and movements from space. Additionally, ground-based instruments like radar, lidar, and weather balloons provide detailed information on cloud characteristics and behavior within the atmosphere.
A radar can detect rotation within a supercell thunderstorm, which is a key ingredient for tornado formation. When a tornado forms within a supercell, the radar can detect the rotation associated with the tornado, providing valuable information for forecasting and warning purposes.
Tornadoes are tracked and predicted using advanced radar systems, such as Doppler radar, which can detect the rotation and intensity of a storm. Meteorologists also analyze weather patterns, atmospheric conditions, and historical data to forecast when and where tornadoes are likely to occur. Additionally, the National Weather Service issues tornado watches and warnings to alert the public about potential tornado activity.
The Magellan spacecraft mapped the cloud-shrouded planet Venus with radar.
A tornado is considered a tornado when a rotating column of air descending from a thunderstorm cloud reaches the ground, causing damage and visible debris swirling in a vortex. The National Weather Service confirms tornadoes based on eyewitness reports, damage assessment, and radar data.
A a radar is better: it can detect a tornado at a distance. A barometer would be of no use unless the tornado came dangerously close.
If a tornado is spotted or is detected by radar, then a tornado warning will be issued.
Given the timing of this question, a tornado warning has been issued for St. Louis, but so far no funnel cloud has been reported. Just strong rotation indicated by radar.
A tornado warning means that a tornado has been spotted or indicated by weather radar in your area. This is a time to take shelter immediately and follow safety precautions to protect yourself from the approaching tornado.

Doppler radar can be used to make such predictions.
Much of the time, yes. However if radar detects strong enough rotation in a storm, indicating a tornado is likely to form soon, that may also prompt a tornado warning.
