Temperatures in the summer are almost as hot as Death Valley, California. In late July, it is not uncommon to find the heat index at 125 degrees. Now our actual temperature only gets to around 104 F, but Mississippi's humidity is normally very high. Because of the Gulf currents and the jet stream, Mississippi is forced to bear a great deal of moisture. Mississippi does not experience much flooding, but rain fall is fairly large.
Most flooding occurs along the Mississippi River from the floodwaters of the North.
Most of the time, the summer weather holds out until late September. Things begin to cool down, but not without the occasional heat blast. By December, Mississippi temperatures drop to the thirties in the northern part of the state. On rare occasions Mississippi does receive snow. Only once every forty or so years, Mississippi has an extreme case of the cold weather.
