Forecast Discussion:
A HEAT ADVISORY IS IN EFFECT FOR THE ENTIRE BRAZOS VALLEY UNTIL 7 PM SATURDAY. Another 100°+ day on the record books for the Brazos Valley, with more triple-digit heat on the way. Afternoon temperatures range 100°-105° each day throughout the weekend across the Brazos Valley. With temperatures on the rise, the humidity also increased on a southerly wind shift. With lower-level moisture on hand, heat index values move into the mid-100s through the next several days, prompting heat advisories through Saturday evening. These heat advisories could be bumped to extreme heat warnings by the middle of the weekend as well. Residents are urged to use caution through the weekend, check on their neighbors and small children, and drink plenty of water.

With the heat being our largest weather concern, many are wondering when we could find some beneficial rain for the area. Thankfully, this heat dome has shifted slightly to the west, placing the Brazos Valley in a northwest flow and opening up the door for added rain chances this weekend. Small disturbances are expecting to roll through the atmosphere overhead, sparking those isolated showers and thunderstorm chances. The rain coverage doesn’t look significant, but if any isolated storms can fire up with the heat of the day, downpours, gusty winds, and brief hail are possible. For now, rain coverage is 20% for Friday, 30% for Friday night, and 20% by Saturday in the Brazos Valley. Sadly, this high-pressure rolls back east next week, bringing hot and dry weather again.

5-Day Weather Outlook:
Friday: High 103. Low 77. Sunny. 20% Chance/Rain.
Saturday: High 104. Low 77. Sunny. 20% Chance/Rain.
Sunday: High 103. Low 77. Mostly Sunny.
