The featured map displays the RUC computer weather model forecast of surface based CAPE for yesterday afternoon. CAPE is a measure of the vertical accelerations possible if air is forced upward initially. Typically, values of around 3,000 indicate severe storms are possible. Due to the extreme surface temperatures and dew points yesterday, values were over 10,000 J/Kg. Values this large are extremely rare.
