Thunder and lightning, and rain, are the highest chance the National Weather Service gives for each day at this spot. Thunder only comes with lightning, and the NWS publishes no separate lightning chance, so one figure covers both.
Severe storms, tornado, hail and damaging wind come from the Storm Prediction Center, as the chance of each within 25 miles. SPC issues tornado, hail and wind chances for today and tomorrow only, one combined severe chance for day 3, and 15% and 30% areas for days 4 to 8, so later days show what SPC has issued and nothing more.

The national outlook, day by day
Loading the latest outlook...
From day 3 the Storm Prediction Center gives one combined chance for all severe weather, so the tornado, wind and hail maps cover today and tomorrow. Days 4 to 8 show only areas with a 15% or 30% chance.
How to read this map
The overall map uses the Storm Prediction Center's five risk levels, from Marginal (level 1) to High (level 5). Areas with only ordinary thunderstorms are shaded light green and have no level.
The tornado, wind and hail maps show the chance of that hazard happening within 25 miles of any point. A 5% tornado chance sounds small, but it is far above a normal day.
