Pressure “systems” (lows and highs) are constantly changing all over the world. Lows are areas
of low pressure with the lowest pressure at the center. Highs are areas of high pressure with the
highest pressure at the center. The way these move from day to day causes the changes in the
weather. Lows usually bring wet, cloudy weather. Highs bring sunnier, dry weather.
