Friday Evening Weather Blog (2/21): Weekend Warm-Up

After a brief cool down -- thanks to a weak cold front -- the Brazos Valley is once again expected to reach temperatures better suited for the month of April.

Coolest Part of the Weekend -- Friday Night

The Brazos Valley woke up to upper 30s / low 40s Friday morning.

Late in the day, high clouds started to stream across the sky. As we embark on the overnight hours, we'll look for those high clouds to thicken a bit.

That said, those clouds won't blanket us enough to keep temperatures from reaching a "chilly" criteria. We'll find area lows falling anywhere between the upper 30s (Northeastern Brazos Valley) to the mid-40s (across most of the area).

For a weekend that will kick off on a cool note -- we'll look for temperatures to take off through the rest of it...

Southerly Winds Do Their Thing

Friday morning brought on a north, dry wind. By afternoon, southerly winds returned -- but too little, too late to really warm the day up.

Saturday -- those south winds will blow through the Brazos Valley at 10-15mph. South winds help warm temperatures -- and the way they do that is by adding moisture to the atmosphere.

We'll kick off the day with dew points (measure of moisture in the atmosphere) in the upper 30s (dry) and finish the day in the low 50s (relatively moist).

Those south winds will bring back overcast skies, temperatures in the mid-70s, and a touch of humidity. They'll also help hold back a cold front -- which looks to get stuck across the northern half of Texas.

Sunday will bring similar conditions -- just a bit more humidity and temperatures closer to 80°.

Winter Air Returns?

I'll be possible.

Signals are that high pressure will amplify over Alaska / Western Canada -- leaving that deep trough of low pressure scooping into Eastern Canada and the Northeastern United States.

Moral of the story? It looks like we COULD be dealing with another strong cold front blowing into the Brazos Valley by mid-week, next week.

That said, there is still a lot of wiggle room with this forecast -- and still many question marks to answer. We'll be monitoring trends over the weekend and into the beginning of next week.

In the mean time, put that cold air in the back of your mind and enjoy the warm air this weekend. Have a safe and fun one.
