Wytheville, VA, to Little Rock, AR, Weather: 7/27/21

I only made it about half as far as I had intended yesterday, ending the night a little early in Wytheville, VA. I ran into some severe storms near Waynesboro, and even had some dime-sized hail.

After significant melting and pouring rain for 10 min after hailing.

I was able to take shelter under an overhang and let the storms pass.

This morning, the weather has been mostly sunny, with mild temperatures, high humidity and calm winds.

The NWS in Blacksburg, VA, forecasts (for Wytheville, VA) a sunny day, with a 20% chance of showers and thunderstorms, and a high temperature of 87 F. The winds will be calm. Wytheville is under a Dense Fog Advisory until 9 AM.

The NWS in Little Rock, AR, forecasts (for Little Rock, AR) a partly cloudy evening, with a low temperature of 76 F. The winds will be from the east at 5 mph, becoming calm.

The SPC Mesoscale Analysis Surface Map shows mild temperatures and high humidity, with cloudy skies (according to the sensors) and calm winds.

The SPC Mesoscale Analysis Pressure Map shows that I will be driving under no strong pressure systems or gradients this morning. The RAP shows this trend will continue for the next six hours.

The Nested NAM simulated reflectivity shows showers and thunderstorms are possible this afternoon across Tennessee, though I will likely be north of them. They will form near I-40, but then move southeast.

The Nested NAM predicts temperatures will rise into the lower 90s F, and then decrease to the mid 70s F overnight.

The Nested NAM shows that the dewpoints will remain in the 70s F, rising slightly through Tennessee and Arkansas.

I have to make up for some lost time, but it’s not too bad. With reduced chances of showers and thunderstorms, hopefully, I will have smooth sailing.
