Breaking space weather news tops today’s Texas Weather Roundup. A strong coronal mass ejection (CME) launched from the Sun early this morning and is expected to hit Earth later tonight. Early analysis suggests a significant geomagnetic storm is possible, potentially reaching G4 strength. That means the Northern Lights could be visible as far south as Texas under clear skies tonight.

Cloud cover won’t be a major issue for most of Texas this evening, with clear skies expected across much of the state. A few upper-level clouds may pass over the Panhandle and West Texas, but most of the state should have great viewing conditions if auroras become visible.

Otherwise, it’s another mild-to-warm day across Texas. Highs will be in the 70s and 80s for most areas, with the warming trend continuing through the rest of the week. South winds strengthen by midweek, bringing high wildfire danger to large portions of Texas—especially North Texas, Central Texas, and the Hill Country—before our next storm system approaches this weekend.

A developing upper-level trough will move into the southern United States Saturday into Sunday, bringing the potential for widespread rainfall and thunderstorms. Some storms could be strong or severe depending on how the system evolves. Timing remains uncertain, but right now the best window for rain and storms appears to be late Saturday night through Sunday.

We’ll be keeping a close eye on both the space weather and the weekend storm potential, so stay tuned for updates.
