Within a week, the Lowcountry will go from flirting with record high temperatures in the 80s to fretting over lows in the 20s.
There’s a word for that: January.
Widely swinging temperatures are closer to normal here this time of year than they are to the extreme. In fact, January temperature highs and lows ranging from the 70s to freezing happen routinely.
There’s never been a winter it didn’t freeze at least once since the official Charleston weather record started in 1938, said State Climatologist Hope Mizzell.
More unexpectedly, there’s only been 26 days with temperatures higher than 80, she said.
In fact there’s an average swing of 36 degrees between the highest daily temperatures during the month.
AccuWeather.com and Weather.com, private forecasting companies, are calling for lows in the 30s starting Monday with at least a few nights in the 20s for most of the area.
Though the lows are predicted to be in the 40s again by Jan. 26, AccuWeather.com’s longest range forecasts call for them to drop at least to the 30s by the end of the month and stay there into early February.
The federal Climate Prediction Center’s one month forecast is for above normal temperatures.
