The Piedmont Triad Region, located in the northern Piedmont section of North Carolina, between the Blue Ridge Mountains and the Atlantic coast, benefits from a temperate climate. The Blue Ridge forms a northeast, southwest barrier with heights occasionally exceeding 3,000 feet.
Winter temperatures and rainfall are both modified by the mountain barrier. Shallow cold air masses moving across the Plains States tend to be stopped or turned aside by the mountains, while deeper masses are lifted in crossing so as to lose some of their moisture and have their temperature raised a few degrees.
Freezing temperatures occur on more than half the winter days, but zero weather is almost unknown. Northwesterly winds seldom bring heavy or prolonged winter rain or snow. Flurries of light snow may fall when cold air blows across the mountains, however, glazing is more common in this region than in most of North Carolina, but only occasionally becomes severe enough to do much damage. Seasonal snowfall has a wide range and there have been a few winters with only a trace of snow. Snow seldom stays on the ground more than a few days.
Summer precipitation is largely from local thunderstorms. The frequency of these showers and the amount of rain received varies greatly from year to year and from place to place. Sizeable areas are sometimes without significant rain in late spring or early summer for two or more weeks, while other areas in the vicinity may be well watered.
There are typically about 217 days of sunshine every year. The greatest amount of rainfall occurs in July and September, while the driest months are February and October. Record precipitation has occurred in recent years at both the maximum and minimum extremes however, most rainstorms are light and do not result in over 1 inch of precipitation. Extreme low and high temperatures are very rare during any part of the year.
Damaging storms are infrequent in the Northern Piedmont area. The highest winds to occur have been associated with thunderstorms, and were of brief duration. Hail is reported within Guilford and Forsyth Counties each year. The occurrence of tornadoes is rare. Hurricanes have produced heavy rainfall here, but no winds of destructive force.
