DISCUSSION
 
 
A WEAK COLD FRONT WILL ADVANCE INTO EAST TEXAS LATER THIS MORNING  
WITH WINDS SHIFTING TO THE NORTH NORTHEAST, ALTHOUGH SPEEDS WILL  
REMAIN LIGHT. THE CHANCE OF SHOWERS IS QUITE LOW BUT STILL CANNOT  
RULE OUT SOME BRIEF LIGHT RAIN, MAINLY THIS MORNING. MINIMUM RH  
VALUES WILL AVERAGE AROUND 50 PERCENT THIS AFTERNOON AS COOLER AND  
DRIER AIR ADVANCES SOUTH BEHIND THE FRONTAL BOUNDARY, WHICH IS  
EXPECTED TO BECOME STATIONARY LATER THIS EVENING. AS A RESULT, THE  
CHANCE OF SHOWERS AND THUNDERSTORMS WILL INCREASE ONCE AGAIN THIS  
EVENING THROUGH THE OVERNIGHT HOURS.
