Can we predict winter storms?
Accurately forecasting winter weather is a complicated process. It starts with a wide network of observing systems such as satellites, Doppler radars and automated surface observing systems. Computer forecast models take this information and estimate what will happen next.
What’s the difference between a storm watch and a storm warning?
A WATCH means that the potential exists for the development of severe thunderstorms or tornadoes, depending upon the specific type of watch issued. – A Severe Thunderstorm Warning indicates that severe weather is imminent in your area or is already occurring (based on either human observation or doppler radar).

How are blizzards detected?
Although blizzards are tracked by satellites, forecasters use computer models to predict their paths. The computers won; areas of the Northeast wound up buried under more than 2 feet of snow. Nonetheless, while computers can often “see” blizzards coming, they’re far from foolproof.
What are the three levels of weather alerts?
In order from least to most threatening, the four-tier approach used by NWS to alert the public of weather hazards includes: outlooks, advisories, watches, and warnings. Hazardous weather is due to occur in the next 3 to 7 days.
What are the different tornado warnings?

How do you detect snow storms?
Detecting Winter Weather. Satellite images are very useful tools for determining cloud patterns and movement of winter storms. By looping a series of satellite pictures together, forecasters can watch a storm’s development and movement.
