CHARLOTTE, NC (WBTV) - Temperatures tonight will threaten record lows in the Charlotte area, with the forecast low of 28° the same as the record of 28° set back in 2007.
This is certainly well below the normal low of 45° for this time of year, however, we are nowhere close to seeing the latest occurrence of sub-freezing temperatures on record. The top 5 latest occurrences of sub-freezing temps in Charlotte range from April 19-May 2.
Average last frost for the Piedmont ranges from late March to mid-April, so we're still in that time-frame as far as that is concerned. But tonight we could see more than a frost, a hard freeze is possible. There is no set definition for a hard freeze, but generally it is considered for our area to be 2-3 consistent hours or more of temps in the upper 20s.
So bottom line.. You'll definitely want to protect your plants tonight. Hopefully this will be the last time you'll have to worry about it for the year. Temperatures will come back up starting tomorrow and for the rest of the week.
