Forecast Discussion:
HEAT ADVISORIES AND EXTREME HEAT WARNINGS ARE IN EFFECT FOR THE BRAZOS VALLEY THROUGH LATE WEEK. Moving into the second half of the week, the Brazos Valley becomes pinned between Tropical Storm Arthur that sits to our south and east in the Gulf and a weak frontal boundary to the north. The combination creates dangerous hot weather and heat index values over the next 48 hours across the Brazos Valley. Across Coastal Texas, heavy rainfall and flash flooding continues as Arthur swirls along the shoreline, moving towards Louisiana and leaving the Brazos Valley drier on Wednesday. A few rainbands are possible on the outer reaches of Arthur through late Wednesday, but many stay dry.

Thursday brings hot and drier weather. Our biggest factor for late week in the excessive heat and humidity across Southeast Texas. With the next cold front approaching the Brazos Valley, we’ll see two major issues locally: additional rain chances and increased heat and humidity levels. Afternoon highs reach the middle/upper 90s across the Brazos Valley Thursday afternoon, with heat index values reaching the lower/middle 110s. A HEAT ADVISORY is in place for the Brazos Valley through the end of the week as a result. Lee County, TX (the exception) remains under an EXTREME HEAT WARNING through Thursday. Please use extreme caution outdoors, take plenty of breaks, and stay hydrated locally. Besides the heat, rain chances are back on the books overnight Thursday, Friday evening, and into Saturday for the Brazos Valley. We’re still uncertain of the timing and location of these rainstorms, as it will depend on where this frontal system stalls out locally. Either way, we’ll continue to monitor the forecast and make adjustments.
