Tuesday Evening Weather Blog (12/3): Temperatures Take a Nose Dive

Unseasonably warm weather is about to be traded out for unseasonable, bitter cold across Texas and the Brazos Valley. Temperatures are expected to fall into the 40s Thursday, then continue to decline through Friday.

Starting with the Warmth...

One more day.

One more day for shorts and t-shirts.

One more day to enjoy stepping outside without second guessing your choice to do so.

We'll look for a foggy start to Wednesday morning alongside temperatures in the low 60s -- roughly 15° - 20° above the normal low.

Afternoon temperatures will reach the upper 70s to low 80s under a mostly cloudy sky. A south breeze will try to kick up to 15mph, at times, and a stray shower blowing in from the south cannot be ruled 100% out.

Don't get too comfortable -- we'll be looking up at cold air spilling into the northern side of Texas.

Arctic Air and a Big Temperature Tumble

We'll start our Friday morning in the mid 60s to low 70s across the Brazos Valley -- the warmest we'll be for the next week or so....

Once the cold front arrives, a 40% chance of showers and isolated thunderstorms will come with that initial wind shift to the north.

After our cold front settles in, temperatures start their nose dive towards the mid-40s to upper-30s by Thursday evening.

As of this forecast, we'll plan for temperatures to continue their slide towards the 30s by early Friday morning. Wake up temperatures on Friday will likely be in the mid-to-upper 30s. From there, we don't expect to warm up for the day...but rather watch temperatures continue to fall off to just about 32° or 33° by sunset Friday.

Don't plan on climbing out of the freezer -- if everything plays out as the forecast looks, we'll remain somewhere between 32° and 33° from Friday afternoon through Sunday morning. (Yep...we are talking all day Saturday)

Rain / Freezing Rain / Sleet

All of the above.....possible.

One reason why temperatures are expected to remain around the freeze mark for so long is because of the scattered rain chance that looks to develop.

Friday's rain looks to fall as a cold liquid. Should the rain continue into the afternoon (and it looks like it will), a mix of freezing rain / sleet / rain becomes possible.

Light precipitation is expected to redevelop on Saturday. Given the near / at freezing temperature forecast, we expect anything that falls will come in a light rain / drizzle / freezing drizzle form.

While travel concerns are not expected initially, we will have to monitor the situation closely. Slick conditions will depend on where temperatures eventually settle up, how much rain falls, and how much of that rain is able to actually fall as a wintry precipitation.

Sunday: Running in the BCS Marathon? Heading out for Church?

It'll be a cold start to the day with temperatures still around 32° to 33° at daybreak. As the atmosphere gears up for yet another shot of cold air early next week, we'll actually see a bit of warming take place in the upper-levels.

That means, cloudy skies and chilly weather remain. However, any precipitation that manages to fall (40%) should do so in the form of a cold rain. We will have to watch for slick spots as dictated by Friday and Saturday's outcome.

Plenty to Monitor

We'll be tracking and keeping up with the lasted data coming into the PinPoint Weather Center.

The latest can always be found on the Weather Page, and of course on Twitter and Facebook.
