ISSUED AT 109 PM CDT THU JUL 16 2026
OTHER THAN A FEW WIDELY ISOLATED SHOWERS AND THUNDERSTORMS,
RELATIVELY BENIGN CONDITIONS ARE EXPECTED THROUGH THE REST OF THE
WEEK. HIGH PRESSURE WILL CONTINUE BUILDING INTO THE REGION THROUGH
THE END OF THE WEEK, FURTHER LOWERING PRECIPITATION CHANCES.
HOWEVER, PER THE TYPICAL SUMMER PATTERN IN OUR PART OF THE WORLD,
WHEN POPS DROP, TEMPERATURES DO NOT. A STRAY STORM OR TWO CANNOT
BE RULED OUT, BUT ANY RAINFALL WILL BE NEGLIGIBLE.
BOTH MINIMUM AND MAXIMUM TEMPERATURES WILL BE ON THE RISE AS A
WARMING TREND BEGINS THIS WEEKEND. ON AVERAGE, TEMPERATURES WILL
RUN AROUND 3 TO 8 DEGREES ABOVE CLIMATOLOGICAL NORMALS, WITH HIGHS
IN THE UPPER 90S TO LOWER 100S. THIS WILL YIELD APPARENT
TEMPERATURES BETWEEN 102 AND 113. AS A RESULT, HEAT RELATED
HEADLINES WILL LIKELY BE NEEDED NEXT WEEK.
