Expert Opinion:
This sounding profile has been modified to reflect the solar heating and the moisture advection into the area. Click to update the Interactive Skew-T with the modified sounding.

Note that the convective temperature has been reached. Although the K index of about 18 indicates only a moderate probability of convection, other parameters point to a good possibility of thunderstorms, possibly severe. The large positive shaded area indicates a high CAPE value of about 2500-3000 J/kg. Furthermore, a LI value of about -7, Total Totals index of about 50-55, and SWEAT of 450-500 also indicate severe convection during the afternoon.
