Wednesday's Shreveport sounding

Posted: Updated:

Tonight's weather balloon data from the Shreveport National Weather Service and plotted in Skew-T form by Rap Ucar shows why there are no storms around.  In blue, is the area of negative energy or the cap.  This layer of dry and warm air at about 750 mb or about 7,000 Feet is keeping buoyant air parcels from rising high enough to realize the 1,300 J/KG-K CAPE or Convective Available Potential Energy (in red) and making storms.

As our next storm system over the 4 corners region gets closer, rising air motion will help remove the cap by cooling and destabilizing the atmosphere.  Then, the parcels can potentially tap into the wind shear, CAPE, moisture and dynamical lift to make storms especially once a dry line/frontal system instigates this process.  This may occur tomorrow.

Stay tuned to KTBS 3 and KPXJ CW 21 for the latest forecasts.
