Climate in the News:

As we begin moving into fall, cold fronts are finally traveling far enough south to impact Texas. With this, an increase in storm activity can be seen as well as the negative impacts many people typically associate with spring weather. On September 25th, Round Rock experienced severe hail up to 4 inches in diameter from local thunderstorms, causing major damage to property in the area as seen in the photo below. As we continue into October, it is important to stay mindful of the current weather conditions in your area and take all necessary precautions to keep your life and property safe.

Weather Synopsis:

A low pressure system made its way into Texas pushing a cold front across the state. At times, this boundary stalled out into a stationary front but was still successful in producing storms along the way. The rest of the week was mostly sunny and uneventful as a surface high pressure center was parked over the state. Below is a 7:00am surface analysis depicting the low pressure system over Texas on September 25th along with its attached stationary fronts.
