Strong Cold Front Arrives in the Brazos Valley Friday

A strong, Arctic cold front is expected to reach the Brazos Valley Friday morning. Rain and thunderstorms are anticipated along the wind shift, followed by falling temperatures through the day.

Storms Ahead of the Front

Thursday brought our last warm and humid day, in the Brazos Valley, for a while.

Temperatures topped off in the upper 70s to low 80s, alongside a breezy southeast wind.

As a few isolated storms came together, a brief area of rotation was noted over Northeast Bryan. This picture was shared on Twitter by Kathryn Westerman, (view from the O&M Building at Texas A&M University) of a brief funnel and wall cloud formation.

Waking Up to Rain, Thunder...and Winter

Latest short range computer models place a line of showers and thunderstorms -- on the leading edge of a northerly wind shift -- to arrive in the Northern Brazos Valley by 2am to 3am Friday.

While this will likely be a skinny line of activity, there could be a few stronger storms with lightning, thunder, and heavy rain.

Once the line of showers and thunderstorms passes, strong north winds will begin to drop temperatures from north to south across the area.

Temperatures Only Fall on Friday

With cold air rushing into the Brazos Valley, daytime "highs" will be achieved around sunrise for most of the area Friday. Temperatures are expected to start in the 60s, when the storms arrive, and end in the 40s by 5pm.

Factor in a north wind blowing between 15mph and 20mph, with gusts upwards of 30mph to 35mph at times, and it will feel much colder than the actual air temperature. Wind chills are expected to be in the 30s by sunset.

Stuck in the Refrigerator

Once the cold front blows through the Brazos Valley, temperatures will trade off between the mid / upper 30s at night and the 40s during the day. Clouds, on & off light rain / drizzle, and a continued breezy north wind will keep the weekend blustery, gray, and at times soggy.

Another widespread rain maker is expected on Monday, which could have temperatures struggling to reach the 40° mark by the afternoon.

Winter Precipitation?

At this time...not expected. That said, if light rain starts back up Sunday evening / early Monday, it won't be 100% out of the question that a bit of light sleet could fall.

Should it occur, ground temperatures will be above freezing, so any precipitation that falls is expected to melt on contact. More details through the weekend should that outlook change.
