DISCUSSION

Issued at 123 AM CDT Wed Aug 12 2026

Mid-level high pressure will dominate the period leading to warm and mostly rain free conditions outside of isolated seabreeze convection each day. As we encroaching on the end of the week, we will see an inverted trough tracking along the southern periphery of the ridge. This will lead to a increase in moisture region, surging PWATs around 2.0 inches (75th percentile of climatology). Expect this to be accompanied with some associated vorticity which will allow for some at least low rain chances (~20%) during the day Friday. Will continue to monitor the need for some short- fused heat related products. We could see heat indices up to 115 at times with dew points around the mid to upper 70s present through the next week. This translates to Moderate to Extreme heat stress conditions. 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.

Min RHs will be in the 20-30% range each afternoon through the end of the week in the western Brush Country and Rio Grande Plains. Low RHs, ERCs in the 70-89th percentile range, and gusty winds will lead to elevated fire weather conditions over this region. A Fire Danger Statement was issued for today from 1 PM through 9 PM.
