UNION COUNTY — After nearly two days of below freezing temperatures Union County will experience a warming trend that will bring above average temperatures and rain by this weekend.
On Monday afternoon, temperatures in Union County began dropping below freezing due to an arctic air mass pulled down from Canada that settled in over the western Carolinas. The mass caused temperatures to drop into the single digits Tuesday morning when the thermostat in the electronic message board outside the Union County Advanced Technology Center stood at 7 degrees. This was 25 degrees lower than the 32 degrees which is the normal low temperature for this time of year.
Temperatures remained below freezing throughout Tuesday, reaching only into the upper 20s before falling to a low of 14 degrees at night. Tuesday’s high temperature was almost 30 degrees lower than the lower 50s which is the normal highs for this time of the year.
Even though it was still very cold, the fact that the temperature fell only into the teens Tuesday night was a sign of a gradual warming trend that will occur during the remainder of this week and into next week.
Neil Dixon, Meteorologist for the National Weather Service in Greer, said this morning that the slightly warmer weather is due to the arctic air mass shifting to the east. He said it will gradually be replaced with warmer, moist air pulled up from the Gulf of Mexico that will, first, cause daytime temperatures to rise above freezing and then bring some precipitation in the form of rain this weekend.
“The center of it is toward the Atlantic so we are seeing some recovery in the low level temperatures,” Dixon said. “The circulation around the high is now drawing air from Florida and across the deep south reaching the western Carolinas. We’ll be in the lower 40s this afternoon.”
Dixon said that while temperatures will again dip below freezing tonight, they will not fall as low as they did earlier in the week. Instead, Dixon said for most areas of Union County the low temperatures will be in the mid-20s.
Temperatures will continue to get warmer and Dixon said the county will go from having temperatures well below average for this time of year to above average by the weekend despite the arrival of another cold front. Dixon said the weekend will not only see above average temperatures but another rainy Saturday.
“All indications are that this weekend into early next week will see temperatures above normal in the upper 50s,” Dixon said. “We will also have to endure another wet Saturday, our sixth wet Saturday in a row, but we should dry out by Sunday.”
Dixon said that while the warm, moist air that will push temperatures up will be succeeded by another cold front, this one won’t be as cold as the one that brought the arctic air mass to the county. He said this will be because the new front will be bringing in air from the Pacific region instead of Canada allowing the milder temperatures to persist.
