A frost advisory continues in the Charlotte region until 9 a.m. Tuesday, as a Canadian high pressure system ushered in cooler-than-normal temperatures.
At 5 a.m., Charlotte Douglas International Airport stood at 37 degrees, which is 11 degrees below normal for this day of the year.
Such temperatures can kill sensitive outdoor plants if left uncovered.
The mercury should eventually rise to a high of 69, or 2 degrees below normal, under sunny skies.
Temperatures are expected to rebound beginning Wednesday, when a low of 42 and a high of 72 are forecast, again with no chance of rain.
Thursday and Friday should be even more pleasant, with respective overnight lows of 47 and 51 and highs of 75 and 74 predicted. Both of those days will be sunny as well.
A dry cold front will approach the Carolinas by Friday, bringing cooler temperatures for the weekend, according to the National Weather Service in Greer, S.C.
Saturday’s high could reach only 68 and Sunday’s 69.
Another front could bring a chance of rain early next week.
