Just as Triangle residents are likely getting used to above-normal temperatures, the word "frost" has reappeared in the weather forecast for next week.
The National Weather Service said it expects the low temperature overnight Monday to slip into the low 30s, and patchy frost could be the result.
Frost would not come without warning, however.
Sunday, when the forecast puts the chance of rain at 70 percent, the high temperatures is not expected to get out of the 40s, and the overnight low is marked as the mid-30s. Monday’s prediction is for mid-50s for a high before the overnight dip.
Never miss a local story.
Forecasters say a low-pressure system that is responsible for the rain in the forecast will be moving away Monday, and that will help bring in a mass of Canadian air.
Warm air from the southwest will chase away that nastiness by mid-week, however, the weather service said.
Normal daytime highs for this time of year are in the low- to mid-60s, and normal lows in the mornings are in the low 40s.
