METEOROLOGIST JEFF HABY
A mid-latitude cyclone brings in clouds and precipitation. It is a low pressure system that has a lifecycle of many days and can
travel over 1000s of miles. They are most common in the middle and high latitudes and the season they are most common is in the
cooler half of the year when the jet stream is more active. The regions that mid-latitude cyclones tend to develop are near mountain
ranges, at ocean/land boundaries and along troughs in the jet stream.
Mid-latitude cyclones are a common weather changer mechanism in the middle-latitudes. They bring in fronts and precipitation systems that
can turn sunny weather to cloudy and damp weather. Mid-latitude cyclones tend to move toward the east or northeast once they mature. Due
to the movement, they tend to influence the weather for a day or two. It is common that the weather will be nice, followed by a day
or two of inclement weather and then followed by the return of nice weather. Mid-latitude cyclones are a major reason that the weather
forecast changes in the future. A cold front and colder air often follows behind a mid-latitude cyclone thus warmer weather is
typically followed by colder weather when a mid-latitude cyclone is forecasted to influence the forecast region.
