High pressure is associated with air that is subsiding, that is to say, falling. Under such conditions the air warms and dries and as it reaches the surface flows away or out of the high pressure area. It is therefore generally accompanied by fair weather - few clouds. Low pressure on the other hand is associated with rising air. When air rises it cools and water vapor condenses to form clouds. The winds about a low pressure center also tend to flow into the low so that if there is a large water source (gulf of Mexico, or the Atlantic ocean) in its path then additional moisture is fed into and subsequently upward forming clouds and rain. Low pressure centers form as waves along frontal zones separating two different air masses. Behind a cold front there is high pressure and fair weather.

There is a story that someone mailed a barometer back to a company and complained that it was broken because it was reading too low. Their house was lost in a hurricane that day. The lowest pressure often read is at the center (eye) of a hurricane. High pressure usually means good weather. If you gently tap an aneroid barometer and note that the needle rises, expect better weather. The opposite is also true.

It depends on whether you need rain or not. Low barometric pressure is associated with storms and rain. High brometric pressure is associated with good weather.
Some parts of Texas had droughts this past summer. The residents there would have welcomed a low reading on a barometer.

it truly is what i believe from journey that dates decrease back to the days of the dinosaurs . I capture better fish when I fish the day earlier a climate replace strikes in, and the day of the replace- this is a falling barometer- after the replace comes by and the skies are sparkling and no clouds in sight is the worst time to fish- this is a turning out to be barometer. My fulfillment has continually been better at the same time as clouds are contained in the sky and espresso. however on prolonged sessions of settled climate, at the same time as that's summer season time warm, besides the actual incontrovertible fact that that's bluebird skies, there'll be a good chew happening at circumstances. that's straight away after the elements replace that the fishing sucks. yet in all honesty, the subsequent fisherman would have the different studies.

It's not a matter of which is "better". It's what might happen to weather as the barometric reading changes from one to the other.
Generally, high pressure brings clear weather, while low pressure is often accompanied by clouds, low ceilings and precipitation.

High. Low means a storm is brewing.
