Tropical Moisture Brings Rain to CTX

Heat into Early Sept; Midweek Rain

DFW Rainless Streak Now in Top 10 All Time

Localized beneficial rain amounts are possible mainly across southeast Central TX midweek. A tropical disturbance is currently in the Gulf, which is expected to move WNW into the Upper Texas coast, bringing increased moisture and rain chances to much of the I-45 corridor late Tuesday through Thursday. Storm coverage will peak in the afternoon and evenings. Not everyone will see meaningful rain! Most likely amounts for SE Central TX are 0.25-1", with isolated higher amounts to 2". North TX is likely to miss out, with only a 5% chance of receiving even 0.10". Regardless, the additional moisture and cloud cover should bring a break to the entire region by cooling temperatures off slightly, although it will also feel more humid.

DFW has a current streak of 46 days without any measurable rainfall (at least 0.01"). This ties with a stretch in 1974 for the 10th longest number of consecutive days without any measurable precipitation. A few spots did get rain in DFW last week with an isolated storm, but the official climate site at DFW Airport only measured a trace of rain, keeping the streak alive. This August in particular is among the driest on record. Only one year has ever recorded 0.00” for the month of August (2000). August 2026 will end up being one of only seven times to only measure a trace for the whole month (1902, 1913, 1929, 1943, 1980, 1999, 2023).
