    Watch or Warning?! Your title says Warning but then you only talk about a Watch. Big difference.

      Both. According to the Weather Channel there is a watch until 9pm and a warning until 4:30. It stated heavy downpours,hail, and wind in excess of 60 mph. Currently, we have heavy winds that just knocked out power and heavy rain and thunder/lightening in the valley.

      I like to always apply it to tornados. Makes it easy to remember :) a watch means conditions are favorable or just right and a tornado/storm might happen. A warning means a tornado has been produced or spotted on the ground. A thunderstorm warning would be the highest level that it’s currently happening in the cell or it’s going to. That’s just how I remember it, I’m sure there are flaws as I’m not a meteorologist and not giving definitions just my interpretation. Hope it helps :)

      Warning is worse.
      From weather.com
      Severe Thunderstorm Watch -conditions are conducive to the development of severe thunderstorms in and close to the watch area.

      Severe Thunderstorm Warning – a severe thunderstorm has actually been observed by spotters or indicated on radar, and is occurring or imminent in the warning area.
