Severe storm spotters are a VITAL part of the warning process! Spotters provide, potentially live saving information to their communities and surrounding locations - and to National Weather Service (NWS) forecasters using the reports to help issue warnings and keep the public updated during severe weather

1) Begin by attending a virtual spotter training class. These are scheduled between March and mid-April. Classes are FREE and take about 1.5 to 2 hours to complete. Anyone can attend a class, but you must be at least 18 years of age to sign-up to be a SKYWARN spotter. The training, taught by NWS meteorologists, is comprised of all of the information that spotters need to be effective and stay safe.

Topics covered in the spotter training class include:

  • Thunderstorm development and features
  • Types of Thunderstorms - especially those that impact Illinois
  • Tornadoes and other rotations
  • Non-tornadic severe weather (Damaging wind, hail, and flooding)
  • Resources for Spotters
  • Spotter Safety
  • Effective Spotter reports

IF you can not attend one of the local spotter classes, there are two online training modules you can take to introduce yourself to the basic spotting concepts. CLICK HERE to access the online spotter training modules.

2) After you have completed a spotter training class, and if you are interested in reporting directly to the NWS Lincoln office you can sign-up to become a SKYWARN spotter. You must be at least 18 years of age to sign-up to be a SKYWARN spotter. CLICK HERE to access the form to sign-up to be a SKYWARN spotter.

3) Report to the NWS Lincoln office as soon as possible, when you witness rotations, flooding / heavy rain, high wind or wind damage, large hail, or damage caused by lightning.

  • Select the "How to Report" tab on this web page for a list of various ways to report to the NWS Lincoln office
  • Select the "What to Report" tab on this web page for a complete listing of what to report.

What Should Spotters Report? 

Important points to remember during severe weather:

  • NWS Lincoln covers 35 counties in central, eastern and southeast Illinois.  Because of this large coverage area, it is important to maintain efficient and effective communication.
  • Take the time to be sure of your observation
  • Take the time to formulate your report before calling.  
  • If you are mobile, make sure you know where you are at all times
  • If the event you're reporting is in the distance (tornado, funnel cloud, etc...) PLEASE report the approximate direction and distance the feature is from you. DON'T JUST GIVE US YOUR LOCATION!! 
  • Remain CALM.  Speak slowly and clearly. 
  • Please do not relay second-hand reports from TV, scanners, etc.

Frequently Asked Questions


Q. What is a storm spotter?

A. The National Weather Service's (NWS) primary mission is to save lives and protect property through the issuance of warnings for hazardous weather. The WSR-88D Doppler Weather Radar is a great tool for detecting and tracking potentially severe storms and essentially all strong and violent tornadoes. However, NWS meteorologists also depend on real-time reports from trained spotters to know exactly what is occurring on the ground under a storm. The NWS trains people to identify severe storms and tornadoes and report them via organized communications networks (primarily local and county emergency management, law enforcement and amateur radio).


Q. What is the difference between a storm spotter and a storm chaser?

A. A storm spotter is volunteer, or paid county or municipal employee who is spotting as a community service. Most spotters work as part of an organized network and are in communication with their community or organization, which is in turn in communication with the NWS. Some spotters are "mobile" spotters in vehicles, but most spot from fixed locations, such as from home, work, or around the community. The purpose of spotting is to alert community officials and the NWS and assist them in warning the public. Schools, hospitals, and other facilities are encouraged to have spotters to alert people in their care of impending severe weather.

Storm chasing involves following a developing thunderstorm to view or photograph severe weather phenomena. Chasing may be done for educational purposes or scientific research but is mostly done for personal fulfillment.

Q. I want to be a storm chaser. What should I do?

A. College of DuPage in Glen Ellen offers storm chasing field trips that are open to students and the public. There are private firms, mostly in the Great Plains, that offer storm chase tours/vacations. Many can be found through an internet search.

Q. How do I become a spotter?

A. Attend a basic severe weather spotter class. Classes are held throughout the area, they are free and open to the public. The class takes about 2 hours. Most classes are held weekday evenings. The training is generally done from March into early April - before severe weather season. The training consists of a slide and video program which teaches potential spotters about severe storm structure, and how to identify cloud features and other environmental clues to identify severe storms and tornadoes. Communications systems are explained so the spotter knows where to report, and how that information is used by the NWS and local officials.  A complete schedule of classes can be found on our website from about February through April. 

Q. Is there a minimum age requirement to become a spotter?

A. Because of the complexity of severe thunderstorm structure and development, and the potential danger involved, spotting is recommended for adults. However, people of all ages attend spotter training classes.  Those ages 10 and up are likely to get the most from the class. Youth who are interested in attending a spotter training class are welcome to attend with a parent or other adult.  

Q. Does the NWS issue a certificate or spotter ID number?

A. The NWS Lincoln office does not issue spotter ID numbers. Certificates are available on request. Some county emergency management agencies issue IDs and/or certificates. Please check with your local officials.

Q. Does the NWS have any training material?

A. In the past, the NWS has been able to hand out copies of the Basic Spotters' Field Guide. However, due to limited budgets, the NWS has made the Field Guide available online. You can find it at: Guide_New.pdf  A pair of online spotter training modules are also available as a good introduction to severe storm spotting. These modules are free - all you need is an account on the COMET MetEd web page. For more info or to take the modules go to :
