NATIONAL WEATHER SERVICE BROWNSVILLE TX  
414 AM CST MON NOV 20 2017  
   
DISCUSSION
 
AN UPPER LEVEL DISTURBANCE WILL MOVE  
EASTWARD ACROSS THE RIO GRANDE VALLEY THIS MORNING AND  
WILL COMBINE WITH INCREASING LOW LEVEL MOISTURE FROM THE  
GULF. THE COMBINATION OF LIFT FROM THE DISTURBANCE AND  
THE INCREASING MOISTURE WILL BRING A SLIGHT CHANCE OF  
SHOWERS TO CAMERON, WILLACY, AND HIDALGO COUNTIES.  
HUMIDITIES WILL BE NEAR NORMAL TODAY FOR THE THREE  
COUNTY REGION, WHILE HUMIDITIES WILL BE SOMEWHAT BELOW  
NORMAL ELSEWHERE. TEMPERATURES WILL BE NEAR OR SOMEWHAT  
BELOW NORMAL ACROSS THE ENTIRE REGION. TEMPERATURES  
QUICKLY BOUNCE UP TO MUCH ABOVE NORMAL VALUES ON TUESDAY  
AS DRY SOUTHWEST TO WEST LOW LEVEL WINDS DEVELOP IN  
ADVANCE OF A COLD FRONT SLATED TO MOVE THROUGH DEEP SOUTH  
TEXAS LATE TUESDAY NIGHT INTO WEDNESDAY MORNING. THIS  
NEXT FRONT WILL BRING CHANCES OF SHOWERS WITH WETTING  
RAINS TO MAINLY LOWER VALLEY LOCATIONS WHEN IT PASSES  
THROUGH.
