Please visit the National Weather Service Interactive Weather Information Network (IWIN) for more information on the warnings.

For each watch, probabilities for particular events inside the watch (listed above in each table) are determined by the issuing forecaster. The "Low" category contains probability values ranging from less than 2% to 20% (F2-F5 tornadoes), less than 5% to 20% (all other probabilities), "Moderate" from 30% to 60%, and "High" from 70% to greater than 95%. High values are bolded and lighter in color to provide awareness of an increased threat for a particular event.
