**OPERATIONAL WEATHER BRIEFING - DURHAM, NC**

Durham is currently experiencing active winter weather with snow showers producing hazardous conditions across the area. Surface temperatures of 18°F with a wind chill of 6°F, combined with north-northwesterly winds at 11 mph, are creating dangerous cold stress conditions. The reduced visibility of 2.6 miles in snow showers, coupled with elevated humidity at 76% and a dew point-temperature spread of only 6°F, indicates saturated atmospheric conditions favorable for continued snow production. The pressure reading of 29.92 inHg suggests we're under the influence of a cold air mass following a departing low-pressure system.

The current synoptic pattern shows cold continental polar air advecting southward behind a frontal boundary, with the NNW wind direction confirming post-frontal flow. The tight dew point spread and complete cloud cover indicate this air mass is being moistened as it moves across relatively warmer surfaces, triggering instability snow showers. These conditions are typical of backside snow events where lake-effect or instability-driven snow bands can develop even without a primary low-pressure system overhead.

**Operational Impacts:** Customer foot traffic will be significantly reduced due to hazardous travel conditions. Lot operations require immediate attention—vehicles need snow clearing for visibility during test drives, and walkways present slip hazards requiring continuous treatment. Staff should anticipate extended commute times and difficult parking lot navigation. The extreme wind chill creates safety concerns for lot personnel; recommend rotating outdoor staff and ensuring heated break areas are available. Vehicle starts may be sluggish in these temperatures, and inventory photography or detailing operations should be moved indoors until conditions improve.
