Thursday Evening Weather Blog (10/24): Cooling Down Friday / Rain on the Way

After reaching afternoon highs in the low 80s across the Brazos Valley Thursday, a weak cold front reaches the area by Friday morning. Temperatures will drop off a bit before weekend rain chances move into the forecast.

Friday Cool Down

Most of the country was reaching for jackets and long sleeves this afternoon -- but Texas and the Brazos Valley was soaking up sunshine and mildly warm temperatures to wrap up the day.

That cooler air starts to slowly trickle into the area overnight -- we'll find morning lows in the low-to-mid 50s Friday morning (similar to Thursday's start). The main difference will be a breeze from the east and northeast at 5-15mph, adding a chill at times.

Sunshine will take over once again Friday afternoon, but because of that cooler air, highs will only manage the mid-to-upper 70s -- seasonable for this time in October.

Rain Chance on the Horizon

Scattered showers popped up over the Desert Southwest this afternoon. That activity is in response to an upper-level low swinging out of the Pacific and slowly moving to the northeast.

As this system swings just north of Texas this weekend, shower and isolated thunderstorm chances will be increasing. We'll keep rain out of the forecast until late Saturday.

By Saturday evening, a slight chance of rain starts to develop. Depending on how rain and storms evolve to the west of our area -- around San Angelo / Abilene -- we could see rain as early as 9pm or 10pm Saturday. Should a few thunderstorms manage to hold together and roll into the Brazos Valley, there could be a brief, strong storm threat to come with them. Main threat will be strong, gusty winds in excess of 40-60mph.

Best wide spread rain chance kicks in Sunday, between sunrise and noon. By later in the day, rain chances should start to push south towards the coast. Sunday service or brunch plans might need an umbrella.

Big Changes Due in Next Week

We've been talking about this for a few days now...and we'll continue to talk about it for several more.

There are still good indications of a strong cold front blowing into the Brazos Valley next week, knocking temperatures down and bringing a decent chance for rain. Those two are almost for certain.

As we sit here together this Thursday evening, the big question mark continues to be the timing of this system. But good news is soon to follow...

Until our upper-level lows that will drive this cold front next week move out of the Pacific Ocean, we don't know much about them other than what we can see on satellite. By tomorrow, the main energy of this system is expected to be in Southwest Canada / Northwest United States, where we can get a better data set on it. Once we have some initial reading there, we'll be able to grasp the timing of this front a bit better. Stay tuned...
