Christmas Road Trip 2018: Day 9

Today, we will travel from Roanoke, VA, to Jersey, VA.

I’ve taken this route a few times; we’ll go I-81 to I-64, then cut through to Fredericksurg, VA, along some smaller routes.

This morning has been cool, clear and still.

The NWS in Blacksburg, VA, forecasts (for Roanoke, VA), increasing clouds throughout the day, with a high temperature of 50 F.  Winds will be calm, becoming westerly at 6 mph in the afternoon.

The NWS in Sterling, VA, forecasts (for Jersey, VA), a mostly cloudy night, with a 60% chance of showers and a low temperature of 35 F.  Winds will be from south at 5-7 mph, becoming west after midnight.

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 cold 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 variable.

The surface pressure chart shows high pressure and no strong pressure gradients over the state today.  The RAP shows that this trend will continue for at least the next six hours.

The HRRR simulated reflectivity shows precipitation is possible this afternoon and evening.

We will see temperatures reach their high in the upper 40s F, around 20 Z along our travel route.

The skies will begin to cloud up this afternoon and remain cloudy this evening.

Today will be a sunny, cool day, but showers will be possible by this evening along our route and at our destination.
