Tornado Watch 836

The weather watch probability tables are a non-operational product currently under

evaluation at the Storm Prediction Center. For each watch, probabilities for particular

events inside the watch (listed below in each table) are determined by the issuing

forecaster. The "Low" category contains probability values ranging from 0-20%, "Moderate"

from 30-60%, and "High" from 70-100%. High values are bolded and lighter in color to

provide awareness of an increased threat for a particular event. You may provide

feedback on this non-operational product by writing an e-mail to spc.feedback@noaa.gov.
