Do bright cores on Anderson weather radar always mean heavy rain?
No, a strong return can include hail as well as heavy rain. The NWS Greenville-Spartanburg Ides of March case study documents softball-size hail reported in Anderson County. Its account describes supercell storms across the region. Use the loop to follow the storm, then read the warning for the expected hazard rather than assigning a hail size from its color.
Why can cold rain become an ice problem in Anderson?
A shallow layer of freezing air near the ground can persist beneath warmer air aloft during cold air damming. The NWS Greenville-Spartanburg ice-storm review explains how that temperature arrangement produced freezing rain across the region. Anderson appears among the event's precipitation observation sites, but a rain total is not an ice-thickness measurement. Compare the surface temperature forecast with winter-weather guidance before interpreting a broad rain shield as harmless.
Where does water leaving Broadway Lake go?
Water discharged from Broadway Lake flows into the Rocky River, which continues into Lake Secession. A South Carolina legislative account also identifies Broadway Creek and Neals Creek at the lake's dam site. When watching prolonged rain, include the connected drainage area rather than just the echo over your own house. The radar loop cannot tell you the lake level or how much water is leaving the dam.
How should Anderson plan outdoor work between summer showers?
Use the temperature forecast as well as the rain loop, because a shower-free interval can still be hot. Anderson's July normal high is 90.3°F, and the normal low is 70.2°F. July averages 3.76 inches of precipitation, compared with 4.18 inches in June. Those monthly totals describe the climate, so check the current storm motion before choosing a work window.
When should you check the Anderson radar?
Thunderstorm peak
May to JulyBefore an outing at Sadlers Creek State Park, look for compact cells growing quickly rather than only storms already overhead. Head to an enclosed vehicle or substantial building when thunder is audible.
Atlantic tropical peak
Mid-August to mid-OctoberIf an inland-moving tropical system threatens a trip on US 29, watch for broad rain bands that keep renewing across the route. Check the destination forecast before treating a temporary dry stretch as the end of the event.
