DISCUSSION

UPPER-LEVEL RIDGING WILL CONTINUE TO BUILD INTO THE REGION THIS
WEEKEND AND ONLY GROWING LARGER AND STRONGER AS WE HEAD INTO THE
START OF NEXT WEEK. AS A RESULT, THE SKIES WILL REMAIN DRY AND THE
BLAZING HEAT WILL SOAR ON HIGH. THE TREND OVERALL THE PAST FEW
DAYS IS THAT WE HAVE UNDERPERFORMED IN TERMS OF AFTERNOON HIGH
TEMPERATURES, SO I HAVE BEEN GOING ON THE LOWER SIDE OF GUIDANCE.
FOR TONIGHT, I FOLLOWED THE SAME SUIT, JUST NOT AS MUCH, I DID
BRING TEMPERATURES DOWN SLIGHTLY, BUT STILL THINK MUCH OF THE
REGION WILL BE IN THE LOWER TO MID 90S. AND TO BE HONEST, THE
AMBIENT TEMPERATURES ARE NOT THE MAIN CONCERN FOR THE NEXT FEW
DAYS, THAT WILL BE THE HEAT INDEX READINGS. TODAY WE WILL BE
BORDERLINE HEAT ADVISORY CRITERIA, MAINLY ACROSS PORTIONS OF DEEP
EAST TEXAS, WHERE THEY WILL BE PUSHING 105 DEGREES. THINKING THAT
ON SUNDAY, WE COULD REACH HIGH ENOUGH ACROSS A LARGER PORTION OF
THE REGION TO NEED SOME SORT OF HEAT HEADLINE, BUT EVEN SUNDAY
LOOKS LIKE WE WILL ONLY BE FLIRTING WITH 105 DEGREES, ASIDE FROM
DEEP EAST TEXAS, WHERE THEY MAY BREAK THAT THRESHOLD.
THE RIDGE ONLY GROWS STRONGER ON MONDAY AND TUESDAY, AND WHILE WE
WILL STILL SEE AMBIENT TEMPERATURES TOP OUT IN THE 90S BOTH DAYS,
HEAT INDEX VALUES COULD REACH DANGEROUS LEVELS ACROSS THE REGION,
ALTHOUGH THEY HAVE TRENDED DOWNWARD SLIGHTLY THIS EVENING. WHILE I
WAS NOT READY TO PULL THE TRIGGER ON ANY HEAT HEADLINES QUITE YET,
I THINK WE WILL NEED TO IN THE COMING DAYS. AND WHILE DIURNALLY
DRIVEN THUNDERSTORMS WILL BE POSSIBLE TOWARDS THE MIDDLE OF NEXT
WEEK, THE HEAT WILL REMAIN IN PLACE WITH HEAT RELATED ILLNESS
CONCERNS ALL WEEK. LASTLY, WE DID SEE SOME STRONG WIND GUSTS ON
FRIDAY ACROSS PORTIONS OF EAST TEXAS, MUCH STRONGER ACROSS THE THE
DFW METROPLEX. THINKING THAT WE WILL SEE SOMETHING SIMILAR TODAY
ACROSS PORTIONS OF EAST TEXAS, WE WILL SEE WIDESPREAD GUSTS OF
AROUND 20-25 MPH AND MAYBE SOME GUSTS UP TO 30 MPH, BUT NOT
WIDESPREAD ENOUGH OR CERTAIN ENOUGH TO GO WITH A WIND ADVISORY.
