The map above shows our dew-point temperatures which is an important temp when it comes to weather. The dew-points help us determine how much moisture is in the atmosphere. If we look at the circle placed over Southern Mississippi we can see temps in the Mid 70’s. That is considered to be very saturated and humid type of weather. When you walk outside it feels very uncomfortable. While if we...

Cumulus clouds are white in appearance and are formed when warm moist air near the earth’s surface is forced aloft by day time heating.

The eastern side of the cold front provides two chances to receive precipitation. The first one is known as a squall line which usually forms some 50-150 miles ahead of the cold front. The squall line can be...

On the north side of the front the temps will be about 15-20 degrees cooler than on the south side of the front. The warm front is depicted on a weather map as having red half circles. The reason for using half circles it...
