Something 'tropical' may develop in the Gulf of Mexico next week. Its origins may be over land right now. How is that possible?
I have been seeing rumblings from meteorologist colleagues about something"tropical" forming in the Gulf of Mexico next week. It remains to be seen whether anything pans out. However, there is something about the potential system grabbing the attention of the weather community. If a tropical disturbance does form, it may develop from a weather system over land right now. While this may be odd,There is nothing phenomenologically unusual about tropical development from mid-altitude MCVs.
A trough of low pressure over western Kentucky, Tennessee and northern Mississippi is forecast to move over the northeastern Gulf of Mexico where a low pressure area could form early next week.Some gradual development of the system is then possible as it drifts westward over the northern Gulf of Mexico through midweek.
Chances of development are 0 percent over the next 2 days but increase to 20 percent over the next 5 days. I have to confess that upon first glanced at the graphic above, I assumed the system was driftingAt this point, I want to revisit Dr. Postel's Tweet. A mid-altitude MCV is a mesoscale convective vortex present in the middle portion of the atmosphere.These swirling areas a few thousand feet above the ground are produced by thunderstorm clusters.
Computer models are hinting at the possibility that a couple of old frontal boundaries may interact in the Gulf of Mexico to enhance convergence needed in the genesis of a tropical disturbance.described how a cyclonic vortex in the middle troposphere, which is often a lingering feature of rain-producing cloud clusters called mesoscale convective systems, can evolve into a warm corm tropical system.
