DISCUSSION
AREAS OF SHOWERS AND THUNDERSTORMS ARE EXPECTED TO CONTINUE
THROUGH THIS EVENING AND MOVE ACROSS THE REGION. WHILE THERE IS A
MARGINAL CHANCE SOME OF THESE COULD BE STRONG TO SEVERE, THE
EXPECTATION IS THAT THE MAJORITY OF ACTIVITY WILL BE OF THE
GENERAL NATURE IN REGARDS TO THUNDERSTORM ACTIVITY WITH OCCASIONAL
LIGHTNING ALONGSIDE GUSTY, ERRATIC WINDS. ANY SHOWERS OR STORMS
THAT DO MOVE NEAR THE SITE THOUGH COULD PRODUCE THIS ACTIVITY,
INCLUDING IF THEY DON'T MOVE DIRECTLY OVER. EXPECT A WESTERLY FLOW
FOR SUNDAY, WITH WINDS SHIFTING FROM A NORTHWESTERLY COMPONENT TO
A SOUTHWESTERLY COMPONENT THROUGH THE DAY. TEMPERATURES WILL BE
NOTABLY COOLER, WITH A CHANCE OF LINGERING PRECIPITATION THROUGH
THE MORNING BEFORE ACTIVITY EXITS INTO THE AFTERNOON.
