.DISCUSSION...

Mid and high level clouds will pass through Sunday with a subtle
increase in humidity values and slow destabilization of the air mass.
Cumulus buildups in the afternoon have a 5-10% chance to mature into a
shower or thunderstorm.  This comes with low confidence.  The main focus
for high based showers and dry thunderstorms will be Sunday night
(20% chance) with a passage of a weak disturbance.  This wave will depart
early Monday with warm and dry conditions through the upcoming week.
