SACRAMENTO, CA - Many people are asking the same question, "Where is the rain?"

The Central Valley has been under the influence of a high pressure system for some time now. It's so strong it's keeping other weather systems from impacting the area and bringing us some much needed rainfall/snowfall.

So, what is a high pressure system? It's an area where the atmospheric pressure is higher than the surrounding area. The characteristics of a high pressure system are winds that move outward and away from the center. When this happens air from above sinks to the surface to take its place. It's this sinking air that's constantly moving toward the surface that increases the atmospheric pressure. It also does a good job of inhibiting cloud development.

This is why high pressure systems are generally known for pretty good weather. Low pressure systems are just the opposite. They are areas of rising air and generally produce clouds and/or storms.
