I don’t know what happened to Weather Underground, our traditional source for verification information. This time around, the problem was attribution. They kept reverting back to weather information for Florence when I sought info on Sumter. It’s too bad for us, because we verified better against Florence’s figures. When running the correct verification, Victoria-Weather fell off, and the cooler numbers in the afternoon, with cooler overnight lows gave the win to the trio of Accuweather, The Weather Service and WeatherNation Actuals: Friday (the 26th) High 86, Low 68 Saturday – High 90, Low 64
Sumter is sort of an in between town. It’s not a coastal town, but it’s not very far inland either. What is the leading factor in the weather in Sumter? I reckon’ we’re about to find out.
At 1055AM, ET, Sumter was reporting a temperature of 81 degrees with sunny skies. After a muggy weekend, an unseasonably strong cold front has swept unpleasantness off the coast, and high pressure has built into the Carolinas. The remnant boundary will lay astride of the coast, and within the convective remainder, a tropical wave will become involved and briefly intensify before pulling the dry continental air further into South Carolina, and the showers and storms at sea further into the Sargasso. All the while, Sumter looks to enjoy a whole lot of sunshine. Tomorrow – Mostly sunny, High 89, Low 65 Saturday – Hot but clear, High 90, low 64

All told, especially after this past week, that’s not really a bad outlook for South Carolina. Here is a look at the western Atlantic satellite, showing the instability off shore.
