Why do surface pressure for inland stations need to be corrected before making a weather map?

They need to be adjusted for altitude, so that all stations report an equivalent sea level pressure. If the raw station pressures are mapped the synoptic features can be obscured by topography. The pressure in Amarillo is always lower than the pressure in Dallas because of the difference in altitude. By correcting both to sea level, significant information about state of the atmosphere can be seen.

What is the abbreviation for automated weather stations?
Automated surface observing system (ASOS)
What is uncorrected barometric pressure?
Uncorrected barometric pressure is essentially BP at sea level. When you see a weather report (Weather Network etc.) the BP you see is corrected for elevation.
Where do weather stations get their information?
meteorologists predict the weather in specialized weather labs and tell the weather stations.
How do you know if the air pressure is the same or different in different places?
Atmospheric pressure is measured by weather stations in many areas, using devices called barometers to monitor the changing pressure. Air pressure varies within weather systems and by altitude (elevation).
What is the difference between surface pressure and sea level pressure?
Surface pressure is simply the air pressure at ground level, anywhere on Earth. Sea level pressure is an adjustment made so that we can compare pressure at stations of different elevations. Sea level pressure is surface pressure if it were taken at sea level. Small differences in air pressure are important in meteorology, which is why we measure pressure precisely. The problem is that pressure is a function of elevation to first order, and weather differences to second. That's why it must be adjusted to be meaningful. Otherwise we would think that Denver, CO is always under an extreme low pressure system.
Which of these are lines on a weather map that connect weather stations that have the same air pressure?
isotherms

Automated surface observing system (ASOS)
Where can a person buy La Crosse brand weather stations?
Weather stations display information such as time, temperature, air pressure and weather predictions. La Crosse is an excellent brand of weather stations that can be purchased at places like Best Buy, Sears and on Amazon.
What is uncorrected barometric pressure?
Uncorrected barometric pressure is essentially BP at sea level. When you see a weather report (Weather Network etc.) the BP you see is corrected for elevation.
Do weather stations normalize air pressure reports to account for altitude?
Yes, all pressure reports you see are what's called "sea level pressure".

The lines of constant pressure shown on the surface pressure diagram are called?
Line of constant pressure shown on the surface pressure diagram are called isobars. Isobars show areas of high pressure and areas of low pressure. The surface pressure diagram can be used to predict weather patterns.
How do meteorologists predict thunderstorms formation?
the monitoring of low/high pressure systems (which are responsible for the storms) by weather stations

How does pressure affect your weather?
Generally with high surface pressure, there is sinking air and clear skies. With low surface pressure there is rising air with clouds and precipitation given sufficient moisture.
What is the surface pressure on the sun?
The surface pressure of the earth is nominally 1013.25 hectoPascals (hP), which is also referred to as 1 The surface pressure of the earth will vary slightly according to weather conditions.
