On a map of barametric pressure, you'll find lines, called isobars that go around centers of high and low pressure. They connect places with equal barometric pressure, so you can see where the highs and lows are. The wind usually follows the isobars, with a slight trend in the direction of the low pressure area.

This is done by examining a large quantity of observation data including surface observations, satellite imagery, radar data, radiosonde data, upper-air data, wind profilers, aircraft observations, river gauges, and simply looking outside.

Isobars: The most obvious feature of a weather map is the squiggly lines. These lines are called isobars. The isobars are lines that connect areas of equal atmospheric pressure. The word isobar, comes from iso=equal and bar=pressure. Anywhere on one line will have the same pressure.

Light rain gives up to 2–4 mm (0.07–0.15 in) of precipitation; Moderate rain gives 5–6 mm (0.19–0.23 in); Rain or strong rain gives up about 15–20 mm (0.59–0.78 in); Rainfall gives more than 30 mm (1.18 in).

Dry thunderstorms that do not produce rain that reaches the ground are most prevalent in the western United States. Falling raindrops evaporate, but lightning can still reach the ground and can start wildfires.

Local weather monitoring

Currently, meteorologists get their data through a blend of government and privately owned weather stations.

Unpredictable Changes: The Earth's atmosphere is constantly changing in ways that are simply not always predictable, even in the short term. Some regions, such as the Midwest, have less predictable weather than other areas, such as the West Coast. Weather also often changes faster at high altitudes.

This is why the meteorological records start in 1927, or at best go back to 1880 from data retrieved and sifted from the earliest meteorological offices and weather stations.

Mississippi is located in the humid subtropical climate region, characterized by temperate winters; long, hot summers; and rainfall that is fairly evenly distributed through the year.

The main severe weather season is in March, April and May, however there is a secondary severe weather season in November and December. Severe thunderstorms produce hail one inch or larger, winds greater than or equal to 58 mph, and tornadoes.

If the oceans and atmosphere continue to warm, sea level along the Mississippi coast is likely to rise between twenty inches and four feet in the next century. Rising sea level submerges wetlands and dry land, erodes beaches, and exacerbates coastal flooding.
