Christmas Road Trip 2018: Day 3

Today, we will travel from Austin, TX, to probably Slidell, LA.  We might drift a little farther, but it just depends how the day goes.

We will take TX-71 to I-10 for today’s travel.

This morning has been cool, partly cloudy and still.

The NWS in Austin, TX, forecasts (for Austin), forecasts (for Amarillo) a partly sunny day, with a high temperature of 68 F.  The winds will be calm.

The NWS in New Orleans, LA, forecasts (for Slidell, LA) a partly cloudy night with a low temperature of 44 F.  Winds will be calm.

The visible satellite imagery is unavailable at this time.  The enhanced infrared imagery shows that there is cloud cover along the entire route to Slidell, LA, so far today.

The surface observations (from the SPC Mesoscale Analysis Map) show mild temperatures and high humidity (based on the surface dewpoint depressions). The skies are clear (according to the sensors) over our route.  Winds are light and variable.

The surface pressure chart shows that there is high pressure along our route, but no strong pressure gradients.

The HRRR simulated reflectivity shows precipitation is unlikely along our route.  This chart has been excluded from today’s post.

We will see our high temperatures somewhere along I-10 near Houston, which will reach nearly 70 F, according to the HRRR.

We are seeing our low temperatures, right now in Austin.  The day will only get warmer from here.

The skies will remain partly cloudy all day, though they will be clearing behind us.  When we reach Louisiana, I expect overcast skies, though they will clear up overnight.

We have another long day ahead of us.  Let’s see how we do.

Thank you for reading my post.
