DISCUSSION
ISSUED AT 144 PM CDT WED AUG 12 2026
MID-LEVEL RIDGING WILL DOMINATE THE PERIOD LEADING TO WARM AND
MOSTLY RAIN FREE CONDITIONS OUTSIDE OF ISOLATED SEABREEZE CONVECTION
EACH DAY. AS WE APPROACH THURSDAY NIGHT INTO FRIDAY MORNING, WE WILL
SEE A MID-LEVEL SHORTWAVE TRACKING ALONG THE SOUTHERN PERIPHERY OF
THE RIDGE. THIS WILL LEAD TO AN INCREASE IN THE MOISTURE REGIME,
SURGING PWATS AROUND 2.0 INCHES (75TH PERCENTILE OF CLIMATOLOGY).
THIS SHORTWAVE WILL BRING PVA TO THE AREA, AND RESULTING SMALL SCALE
LIFT WILL ALLOW FOR LOW RAIN CHANCES (~20%) DURING THE MORNING AND
AFTERNOON ON FRIDAY.
WILL CONTINUE TO MONITOR THE NEED FOR SHORT-FUSED HEAT RELATED
PRODUCTS. WE COULD SEE PEAK HEAT INDICES OF 110 TO 115 WITH DEW
POINTS IN THE MID TO UPPER 70S INTO NEXT WEEK. THIS TRANSLATES TO
MODERATE TO EXTREME HEATRISK CONDITIONS. AN ADDITIONAL RISK FOR
ELEVATED FIRE WEATHER EXISTS OVER THE RIO GRANDE PLAINS INTO THE
WEEKEND DUE TO LOW RH (~25%) AND SUSTAINED 20MPH WINDS GUSTING TO
25MPH. WE STRONGLY ENCOURAGE THE PRACTICE OF HEAT SAFETY IN THESE
CONDITIONS. TAKE FREQUENT BREAKS AND REMEMBER TO STAY HYDRATED,
CHECK THOSE BACKSEATS, AND AVOID LONG EXPOSURE IN THESE
TEMPERATURES. FOR MORE INFORMATION BE SURE TO CHECK OUT
WEATHER.GOV/HEATSAFETY.
