.DISCUSSION...
Daytime hit-or-miss rain showers and isolated thunderstorms today
will eventually give way to more organized severe thunderstorms
this afternoon and evening. All severe threats are present,
including lightning but recent rainfall and a moist atmosphere
should lessen fire weather concerns somewhat this weekend and
into early next week. A warmer and drier weather pattern sets up
later next week.
