During certain times of the year, dramatic weather changes can occur quickly. One day it’s beautiful, 71 degrees and sunny, and the next day there’s a drastic 40 degree drop in the temperature.
That happened here in Texas over Christmas in 2009. A drastic drop in the barometric pressure started to occur the day before Christmas Eve. On Christmas Eve day a blizzard blew in bringing a heavy snow/rain and sleet mix with 45 mph winds. For a native Texan, it was miserable.
Drastic weather changes can cause problems for both your horse and you. When the barometer drops dramatically prior to a big storm, some horses, as well as people, can experience ill effects.
