Air Masses and Moisture

Navarre's location in the northern Gulf Coast allow for a mild-dry winters and hot-humid summers. The proximity to the Gulf Coast gives way to a Maritime Tropical air mass the majority of the time. This air mass is created due to the warm surface temperatures of the Gulf of Mexico that is fed by the Gulf-stream ocean current. 


The warm waters in the area, especially in the summer, feed into the high amounts of evaporation. As a result of the summer sun bearing down on the mainland, the suns energy is adsorbed and then radiated back into the air saturated with water vapor. With these processes in place it allows for daily afternoon thunderstorms and rain showers because of the rising, and then drastically falling pressure.   


Severe weather systems result often from the passing of large frontal systems of low pressure expanding well into the interior of the country all the way south to the Gulf of Mexico's warm waters. These fronts collide with the high pressure system previously in the area and create inclement weather. These storms typically create severe weather, and commonly spawn tornadoes.

On rare occasions, Continental Polar air masses will dip down into the area and push temperatures below freezing during the nighttime low. This is a result of the Polar high being moved by the jet-stream to the extreme southern United States.
