Currently, there is an upper level trough digging in the midwestern US causing the eruption of many many thunderstorms across the Ohio Valley and the Southern United States. Over the last several hours, bits and pieces of this upper level trough have been breaking off and heading off in different directions. The northern end of this trough appears to have the most energy. This is rather dangerous when it comes to tropical formation. As this trough moves east, the southern end still has enough energy to spark off showers and thunderstorms over the Gulf region. Why is this dangerous? Because many storms have formed in the month of June on the tail ends of fronts and troughs due to a turning in the atmosphere caused by the upper-to mid level interaction of the trough with the t-storms as they plow to the east. Several of the models this afternoon changed their tune and show a possible low forming at the tail end of this trough. Again, frontogenesis is the main cause of MANY TROPICAL CYCLONES that have formed in the month of June. Keep your eyes on the GULF and the interaction of the t-storms with the trough as it moves east. This could be our next storm.
Watch this loop carefully
