STATUS: IOP

The evolution of today’s weather is very uncertain.  There is a squall line to the west of the area that could advance through the study area this afternoon.  Or it could weaken/dissipate, and be followed by new activity late this evening/tonight.  Or… name your scenario.

Because of the uncertainty, the sounding systems will be deployed near TTU Stesonet fixed surface observing sites, and study the evolution of CAPE.  It should be noted that at least on set of numerical guidance suggests that CAPE will remain small, and then go to zero for the remainder of the day as the cold pool from convection to the west advects across the area, or is renewed if the convection persists.

The in situ observing platforms will remain close to Huntsville until the evolution becomes more clear, and a target storm can be identified.  The MAX mobile Doppler radar will be deployed to Courtland AL airport, and the Purdue X-POL likely will go to the Tanner site later this afternoon.
