With SoCal seeing a heat advisory and warning for the first time ever in winter, I decided to look at the list of weather events that trigger storm watch. I knew heat advisories and warnings do not as we had them in the summer. But it was interesting to see the wind chill warning does? This doesn't make sense. Why wind chill when heat is much more likely to put a strain on the grid and trigger brown and blackouts? Wind chill itself is just how it feels to a person, not how bad the weather is. If the wind is strong enough to play a roll in the wind chill, then the wind advisory or warning itself is already a trigger. Extreme cold by itself is not a cause for storm watch.
