.DISCUSSION...
THE COMBINATION OF WEAK UPPER LEVEL WEATHER DISTURBANCES AND SOME
INCREASE IN MID LEVEL MOISTURE WILL RESULT IN THE DEVELOPMENT OF ISOLATED
SHOWERS AND THUNDERSTORMS IN THE AREA THIS AFTERNOON AND EVENING. THE
THREAT OF ISOLATED SHOWERS AND THUNDERSTORMS WILL PERSIST THROUGH
SUNDAY. OVERALL THE ATMOSPHERE WILL STILL BE FAIRLY DRY AND THE MAIN
THREAT FROM ANY STORMS IN THE AREA WILL BE VERY GUSTY...ERRATIC OUTFLOW
WINDS OF 40 TO 50 MPH. THE STORMS WILL BE FAIRLY ISOLATED BUT ANY
NEARBY STORMS CAN PRODUCE STRONG OUTFLOW WINDS MANY MILES FROM THE PARENT
STORM. OTHERWISE...IT WILL CONTINUE QUITE WARM AGAIN TODAY WITH LOW
MINIMUM RELATIVE HUMIDITIES SIMILAR OR ONLY SLIGHTLY HIGHER THAN FRIDAY.
A SLIGHT INCREASE IN MOISTURE LEVELS IS EXPECTED ON SUNDAY.
