AccuWeather.com meteorologists are monitoring the potential for a severe weather outbreak in the southern Plains Monday.
While the last part of summer into early fall typically brings a great decline in the amount and intensity of thunderstorms, a secondary severe thunderstorm season ramps up in the fall.
This phenomenon occurs as the jet stream strengthens and begins to move southward from Canada and comes in contact with an extreme temperature contrast.
The number of days with thunderstorms, let alone severe weather, are rare in comparison to the spring.
During the fall, the incidents tend to focus during the couple of times a month when the perfect conditions come together.
The vast area of warmth on the Plains now is one of the necessary ingredients.
Another ingredient is a chilly air mass which will be invading the Intermountain West and northern High Plains tonight.
A cold front marking the leading edge of this chilly air will then interact with the warmth in the central and southern Plains Monday, setting the stage for thunderstorm development.
Areas from southern Iowa to northern Texas are at risk for the storms beginning on Monday.
During Tuesday, the threat area will extend from southeastern Missouri to Louisiana and east Texas.
Thunderstorms that develop across these areas will be capable of producing damaging wind gusts along with large hail and flooding downpours. Since there will also be substantial wind shear with this situation early next week, a tornado threat will also exist.
The approach of the front will also mark a rebound of drenching downpours and flooding in the lower Mississippi Valley this week.
