Possible MCC early Monday AM
Check out these clusters of convection (thunderstorms) that have formed in northern Nebraska and southern South Dakota. Upper air flow is from the NW to the SE. As we've seen recently, these clusters have led to organized complexes of showers and storms or otherwise named, Mesoscale Convective Complexes (MCC). Along the leading edge winds can race at better than 60 mph and embedded cells often contain hail. So will we be dealing with such a complex tomorrow morning?
This map highlights an average wind field aloft, coupled with precipitable water; the amount of moisture that is contained in a vertical column of the atmosphere if you were able to squeeze it out. By this alone, if the complex hangs together, it's quite likely that some of it will impact our area early tomorrow. Usually throughout the course of the evening it becomes apparent, by mostly monitoring radar and satellite data, how developed these systems will become.
Drew Michaels will have the latest tonight at ten. Stay tuned!
