There are several reasons why I am calling for SEVERE thunderstorms:
First: Dew points will be on the high side, for this time of year. (Dew points likely around 65 degrees.)
|Sunday Dew Points|
Second: Temperatures from 75-80 degrees.
Third: Precipitable water content will be 1.25 to 1.75 inches (moderate moisture content). P.W. is the amount of moisture that exists in the complete vertical column, above our heads.
|Precipitable Water Content|
EHI > 1
|Severe Weather Likely|
|1 to 5||up to F2, F3 tornadoes possible|
|5+||up to F4, F5 tornadoes possible|
