As high pressure builds into Central Texas this week, residents can expect a generous helping of sunshine and dry conditions stretching into the weekend. The warming trend will be unmistakable, with daytime highs climbing into the low to mid 90s by Friday, well above seasonal norms.

In the Austin and San Antonio corridor, isolated light showers may linger west of US 83, particularly across the Rio Grande Plains and into the Edwards Plateau. But for most, the skies will clear as the day progresses, ushering in warmer temperatures ranging from the upper 80s to lower 90s. Interestingly, despite the heat, these highs remain slightly below the historical average for September 8th.

KNCT Meteorologist Bill Hecke kicked off the morning with a calm forecast: “Expect a mix of clear and partly cloudy skies to start the day, with temperatures hovering in the 60s. Light northeasterly breezes will flow at 5 to 8 mph. Some spots may experience brief patches of shallow fog early on.”

Skies will remain mostly clear to partly cloudy, with afternoon highs reaching the mid-80s. Winds will shift to the east, blowing gently at 5 to 10 mph.

Looking ahead, a drier airmass will dominate much of the week, bringing a unique blend of above-average high temperatures and below-average overnight lows. But by the weekend, increasing moisture will return to the Coastal Plains, nudging low temperatures back toward seasonal norms and reintroducing slight chances of rain across the region.

Meanwhile, the National Weather Service is keeping a close eye on more volatile conditions elsewhere. A Slight Risk (level 2/5) of severe thunderstorms has been issued for parts of the Central and Southern High Plains, where upper-level energy and Gulf moisture are expected to spark storms capable of producing frequent lightning, damaging winds, hail, and isolated tornadoes.

Across the Northwest, Air Quality Alerts remain in effect due to wildfire smoke, while a cold high-pressure system over the Ohio Valley has triggered Frost Advisories from the Upper Midwest to the Northeast.

In the Southeast, a lingering front will continue to generate showers and thunderstorms along the Gulf Coast and Florida through midweek. Moisture streaming from the Atlantic is expected to bring light rain as far north as New England by Wednesday.
