Columbia, SC, to Tuscaloosa, AL, Weather: 11/11/21

I am continuing my trek west.

This morning, the weather has been partly sunny, with mild temperatures and calm winds.

The NWS in Columbia, SC, forecasts (for Columbia, SC) a partly sunny day, with a 30% chance of showers and a high temperature of 74 F. The winds will be calm, becoming southerly at 5-7 mph in the afternoon.

The NWS in Peachtree City, forecasts (for Atlanta, GA) a mostly cloudy day, with a 40% chance of showers and a high temperature of 69 F. The winds will be from the south at 5-10 mph, gusting to 20 mph.

NWS in Birmingham, AL, forecasts (for Tuscaloosa, AL) decreasing clouds, with a low temperature of 44 F. The winds will be from the west at 5-10 mph, becoming northeasterly after midnight.

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

The SPC Mesoscale Analysis Pressure Map shows that we will be under high pressure and no strong pressure gradients. The RAP shows the pressure will drop with diurnal heating over the next six hours.

Visible satellite image shows a cloudy day for me.

The Nested NAM simulated reflectivity shows I will pass through a squall line sometime today.

The Nested NAM predicts temperatures will rise into the upper 60s F, and then decrease to the upper 30s F overnight.

The Nested NAM shows that the dewpoints will rise into the 60s F.

The Nested NAM shows strong wind gusts are possible ahead of the cold front, particularly in the early afternoon over Mississippi and in the mountain gaps towards evening.

The Nested NAM predicts cloudy skies for most of my travels today.

I will pass through a squall line sometime today, but I’m not exactly sure when. I will have lunch with my son and head west. I don’t know exactly when I’ll meet the line. I’ll keep my eyes open even though it is expected to remain below severe limits.

I didn’t do a lot of investigation today, as I’m already behind schedule, but the idea is that a mid-latitude cyclone is dragging its cold front across the south, hence the squall line.

Thank you for reading my post.
