**Meteorological Brief - Charleston, SC Operations**

Charleston is currently experiencing anomalous winter weather with active snow showers and subfreezing temperatures of 21°F. A significant wind chill factor has reduced the apparent temperature to 8°F due to sustained northwest winds at 14 mph. The high relative humidity of 89% combined with the minimal temperature-dewpoint spread of just 2°F indicates a saturated atmospheric profile, which is sustaining the ongoing precipitation. Visibility has been reduced to 2.5 miles under cloudy skies, with the current barometric pressure of 29.97 inHg suggesting a stable weather system is influencing the region.

These conditions are consistent with a cold air mass advection pattern, with northwest winds ushering Arctic air behind a frontal system. The fetch across relatively warmer coastal waters is likely enhancing moisture availability, creating favorable conditions for snow shower activity despite Charleston's coastal location. This setup typically produces intermittent but potentially impactful winter precipitation for the Lowcountry region.

**Operational Impacts:** Expect hazardous conditions for lot operations with snow accumulation potential on vehicle surfaces and walkways. The wind chill presents safety concerns for technicians and lot staff working extended periods outdoors—recommend rotation schedules and warming breaks. Reduced visibility may impact customer traffic and test drive operations. Monitor pavement temperatures closely, as the current atmospheric conditions favor black ice formation on sales lots, service lanes, and adjacent roadways. Prioritize de-icing high-traffic areas and consider deploying additional personnel for vehicle preparation under covered areas where possible.
