.DISCUSSION...
EXTREME AND POTENTIALLY LIFE THREATENING HEAT WILL BE THE MAIN
HAZARD OVER THE NEXT FEW DAYS.

FOR TODAY AND TONIGHT...A COMPACT UPPER DISTURBANCE WILL BRING A
VERY LOW CHANCE AT A STRAY SHOWER OR STORM ACROSS MAINLY EASTERN
OKLAHOMA...THOUGH SOME OF THIS ACTIVITY COULD SCATHE PARTS OF
NORTH CENTRAL OKLAHOMA BEFORE SHIFTING EAST. ELSEWHERE...RETURNING
SOUTHERLY SURFACE WINDS...AND INCREASING HEIGHTS ASSOCIATED WITH A
BUILDING MID LEVEL RIDGE WILL RESULT IN INCREASING TEMPERATURES.
EXPECT AFTERNOON HEAT INDICES WELL OVER 100 DEGREES MOST
PLACES...WITH MUCH OF CENTRAL AND SOUTHERN OKLAHOMA...AND WESTERN
NORTH TEXAS SEEING HEAT INDICES BETWEEN 105 AND 109 DEGREES. A
HEAT ADVISORY WILL REMAIN IN EFFECT FOR MUCH OF CENTRAL AND
SOUTHERN/EASTERN OKLAHOMA.

AS FAR AS HEAT IS CONCERNED...THINGS WILL ONLY GET WORSE AS WE
HEAD INTO THE WEEKEND. SURGING MID LEVEL TEMPERATURES AND
SOUTHWESTERLY SURFACE FLOW WILL PROMOTE A PERFECT STORM FOR
EXTREME HEAT. COMBINE THIS WITH RELATIVELY HIGH AFTERNOON
HUMIDITIES...AND YOU HAVE A RECIPE FOR DEADLY HEAT. THIS WILL BE
THE CASE THURSDAY THROUGH SUNDAY...WITH WIDESPREAD HEAT INDEX
VALUES IN THE 105 TO 110 DEGREE RANGE. A FEW PLACES COULD EVEN TOP
110...REQUIRING EXCESSIVE HEAT WARNINGS. THIS WILL BE THE HOTTEST
STRETCH OF DAYS WE HAVE SEEN SO FAR THIS YEAR. PLEASE TAKE IT
SERIOUSLY! HEAT KILLS OVER 100 PEOPLE ON AVERAGE ANNUALLY! HYDRATE
AND STAY INSIDE DURING THE HOTTEST HOURS OF THE DAY (NOON TO 8
PM).

A WEAK FRONT MAY ATTEMPT TO MOVE INTO OKLAHOMA BY THE MIDDLE OF
NEXT WEEK...RESULTING IN SLIGHTLY LESS HOT CONDITIONS...AND A VERY
SLIGHT CHANCE OF STORMS ACROSS FAR NORTHERN OKLAHOMA...BUT
CONFIDENCE IN FRONTAL PASSAGE IS RELATIVELY LOW. EVEN IF THIS PANS
OUT...LESSER TEMPERATURES ARE OFTEN MET WITH GREATER HUMIDITY
VALUES...RESULTING IN PERSISTENCE OF HIGH HEAT INDICES...SO LITTLE
RELIEF IS VISIBLE IN THE NEAR FUTURE.

THANKS FOR THE MEMORIES...IT HAS BEEN AN HONOR TO SERVE THE FINE
PEOPLE OF OKLAHOMA AND NORTH TEXAS. NOW ON TO THE NEXT
CHAPTER...LIVE LONG AND PROSPER...AND DRINK LOTS OF WATER!
