A Flash Flood Watch has been issued through Saturday night for the majority of the Midlands and western parts of Pee Dee and the LowCountry.
A near-stationary cold front was continuing to situate itself over the Palmetto State Saturday delivering rounds of showers and isolated thunderstorms to the region. A deepening low pressure system rising from the Gulf of Mexico is expected to cross into the state from the south late Saturday afternoon. This low pressure system will help to amplify the stationary cold front over South Carolina, which will increase shower activity throughout the rest of the evening and into the overnight. Strong storms are possible but the main threat will be the heavy rainfall. Weather models have been indicating near record rainfall levels with amounts of 2 to 4 inches possible.
Fortunately, this low pressure system will also aid in pulling the cold front away from the area and move it closer to the Atlantic coastlines through Saturday night and into Sunday morning. A few scattered showers will be possible, mainly in eastern parts of Pee Dee and the LowCountry, Sunday morning but conditions will gradually clear from west to east with the passage of the cold front.
Temperatures are expected to return to near-seasonal to start off the first full work week of 2021. High temperatures will be mainly in the 50s in parts of the UpState with slightly warmer conditions, in the upper 50s to lower 60s, across the Midlands and towards the Atlantic coastlines.
