Christmas Road Trip 2018: Day 8

Today, we will travel from Atlanta, GA, to Roanoke, VA.

We will take I-75 for much of today’s travel, though we may take US-82 at some point, depending on traffic.

This morning has been cool, sunny and still.

The NWS in Peachtree City, GA, forecasts (for Atlanta, GA), a mostly sunny day with a high temperature of 50 F.  The winds will be from the west at 5-10 mph.

The NWS in Blacksburg, VA, forecasts (for Roanoke, VA), a mostly clear night with a low temperature of 31 F.  Winds will be from the west at 11 mph, gusting to 20 mph.

The visible satellite imagery shows very few clouds over our route this morning.  This chart has been excluded from today’s post.

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

The surface pressure chart shows the mid-latitude cyclone has moved away, leaving higher pressure and a slight pressure gradient in its wake.

The HRRR simulated reflectivity shows precipitation is unlikely.  This chart will be excluded from today’s post.

We will see our high temperatures in Atlanta around 21 Z.

The skies will be clear all day along our route.  This chart will be excluded from today’s post.

Today will be a sunny, cool day.  I’m getting a cold, so I’m annoyed with the cold weather in the south.

Thank you for reading my post.
