DISCUSSION
 
 
EASTERLY WINDS UNDERNEATH HIGH PRESSURE THIS AFTERNOON ARE  
EXPECTED TO CONTINUE OVERNIGHT TONIGHT. RAIN CHANCES ALONG WITH  
ISOLATED THUNDERSTORM CHANCES BECOME POSSIBLE ACROSS SOUTHEAST  
OKLAHOMA DURING THE DAY MONDAY AS MOISTURE FROM TROPICAL STORM  
BETA BEGINS TO LIFT INTO THE REGION. THESE PRECIPITATION CHANCES  
ARE FORECAST TO SPREAD ACROSS EASTERN OKLAHOMA AND NORTHWEST  
ARKANSAS MONDAY AFTERNOON AND CONTINUE INTO WEDNESDAY BEFORE A LOW  
PRESSURE SYSTEM OVER THE REGION EXITS TO THE EAST. RAINFALL  
AMOUNTS IN THE 1 TO 3 INCH RANGE WITH LOCALLY HIGHER WILL BE  
POSSIBLE ACROSS PARTS OF SOUTHEAST OKLAHOMA INTO WESTERN ARKANSAS  
WITH LESSER AMOUNTS FOR NORTHEAST OKLAHOMA. HIGH PRESSURE LOOKS TO  
SPREAD BACK OVER THE REGION FOR THE SECOND HALF OF THE WEEK. WITH  
THE INCREASING MOISTURE AND PRECIPITATION CHANCES, FIRE WEATHER  
DANGERS TONIGHT THROUGH WEDNESDAY SHOULD REMAIN LOW.
