DISCUSSION
ISSUED AT 1258 PM CDT THU AUG 7 2025
TYPICAL SUMMERTIME WEATHER CONDITIONS ARE EXPECTED ACROSS OUR
FORECAST AREA INTO LATE NEXT WEEK. A STOUT UPPER-LEVEL RIDGE OF HIGH
PRESSURE OVER THE DESERT SOUTHWEST WILL BREAK DOWN OVER THE NEXT FEW
DAYS AND ALLOW A MORE ZONAL FLOW PATTERN TO DEVELOP OVER THE
NORTHERN CONUS. TO THE SOUTH, A TROPICAL WAVE WILL BRING THE RETURN
OF EASTERLY FLOW AND DEEPER 2+ INCH PWAT AIR TO OUR REGION. THIS
WILL RESULT IN BETTER RAIN CHANCES AND MORE HUMIDITY BY THE EARLY
PARTS OF NEXT WEEK. AT THIS TIME, IT APPEARS THAT SOME PARTS OF THE
FORECAST AREA COULD END UP WITH DANGEROUS HEAT STRESS CONDITIONS
(HEAT INDEX >105), BUT RAIN CHANCES LIMIT CONFIDENCE OF HEAT IMPACTS
AT THIS TIME. /NF/
