 The Storm Prediction Center is a branch of the NWS and provides data to the public about severe weather as well as other hazardous weather.
 ===== Severe Weather =====
-The SPC issues probability maps for days 1 through 8, but in different forms. The day 1 always provides the probability of tornadoes, wind, hail, and the risk of severe weather. Days 2 and 3 only provide the risk and probabilistic outlook for any severe weather type. Days 4 through I provide only the probability of severe weather in general.

-  * Slight risk
+  * Slight risk - medium chance of having high winds of 60mph+, hail greater than 1", low chance of a tornado in the area.
-  * Enhanced risk
+  * Enhanced risk - High chance of high winds 60mph+, hail greater than 1", possibly larger than 2", medium risk of a tornado in the area.
-  * Moderate risk
+  * Moderate risk - very high chance of high winds 60mph+, hail greater than 1", possibly larger than 3", very high risk of a tornado in th area.
