DISCUSSION
Issued at 113 PM CDT Fri May 29 2026
Through The Weekend...
Some weak ridging is expected to build into the area, which should curtail our rounds of precipitation that we've been seeing the last few days. Unfortunately, or fortunately, depending on how much folks desire for rain, we will still see intermittent showers particularly in our eastern counties, daily. An embedded thunderstorm or two can't be ruled out, but there should be a near zero chance for severe weather associated with these thunderstorms. Overnight PoPs remain below 20% for the weekend.
For Next Week...
Diurnally driven convection will be the theme next week, as our PoPs climb from 20-30% early in the week, to mid 50s during our daytime hours. This will be due to our overall pattern anchoring in, and daytime return flow continuing to feed in more moisture over the area. Temperatures are expected to climb back into seasonal norms with highs Sunday/Monday in the low 90s, which slowly cool about a degree or two everyday to the mid 80s next Friday. Humidity is expected to hover from 55-65% during our daytime hours causing our heat index values to reach triple digits early next week, along and south of I-20.
About mid weak guidance does pick up on a weak front nudging its way into the area, which could bring relief to those heat index values, and at the moment it looks as though the GTR area has the highest confidence for a subtle decrease in both temp and dew points. All other areas could see heat index values drop below the triple digit threshold as well, bringing some much needed relief./OAJ/
