UPPER RIDGE LIFTS NORTHWARD ENOUGH TO ALLOW EASTERLY FLOW ACROSS
NORTH CENTRAL TEXAS.  THIS WILL RESULT IN AFTERNOON AND EVENING
THUNDERSTORMS...MOST NUMEROUS SOUTH...ACROSS THE REGION AND
TEMPERATURES A FEW DEGREES COOLER.  UNFORTUNATELY...HUMIDITIES WILL
BE HIGHER...SO AFTERNOON HEAT INDEX VALUES WILL NOT DROP.  FORECAST
MODELS BRING A WEAK COLD FRONT INTO NORTH TEXAS TUESDAY...BUT IT
WILL BE HARD TO PENETRATE THE UPPER LEVEL RIDGE.  SHOULD THE FRONT
MAKE IT THIS FAR SOUTH...WE COULD SEE AN INCREASE IN THUNDERSTORMS
TUESDAY AND WEDNESDAY.  TEMPERATURES WILL CONTINUE AT OR ABOVE
NORMAL THROUGH THE SEVEN DAY FORECAST PERIOD.
