DISCUSSION...
UPPER LEVEL HIGH PRESSURE SYSTEM WILL CONTINUE TO DOMINATE THE
WEATHER PATTERN OVER THE FOUR STATE REGION FOR MUCH OF THIS
WEEK. AS A RESULT THE REGION CAN EXPECT HOT TEMPERATURES
WITH UPPER 90S TO TRIPLE DIGIT AFTERNOON HIGHS. ALSO WITH THE
AVAILABLE MOISTURE THE HEAT INDEX VALUES WILL BE IN EXCESS OF
105 DEGREES FOR MUCH OF THE AREA AND WITH VALUES RANGING TO NEAR
110...EXPANDED THE HEAT ADVISORY FOR THE DAY TODAY. DEW POINTS
WILL BE MIXING OUT OVER PARTS OF EAST AND NORTHEAST TEXAS AND
WILL NOT SEE THE HIGH READINGS ABOVE 105 THERE. TOWARD MID TO LATE
WEEK THE UPPER RIDGE RETROGRADES INTO TEXAS WITH A WEAK SURFACE
COLD FRONT BACK DOORING INTO THE FOUR STATE REGION. THIS MAY ALLOW
FOR AN INCREASE IN RAIN CHANCES AND IN WAKE OF THE
BOUNDARY...SLIGHTLY COOLER DAYTIME AND OVERNIGHT LOWS FOR PARTS OF
SOUTHWEST ARKANSAS...SOUTHEAST OKLAHOMA AND PARTS OF NORTH CENTRAL
LOUISIANA WITH THE HIGHER READINGS OVER EAST AND NORTHEAST TEXAS
AND PARTS OF WESTERN LOUISIANA. THE WEEKEND MAY SEE A LITTLE
RELIEF IN THE HEAT...BUT BY THE START OF NEXT WEEK THE RIDGE
STARTS TO SHIFT EAST AND RETURN THE UPPER 90/S TO NEAR TRIPLE
DIGIT HIGHS AGAIN. /06/
