GREENVILLE, S.C. (FOX Carolina) – We’re issuing First Alert Weather Days for Thursday and Friday. A tropical disturbance drifting out of the Gulf combines with an approaching cold front to bring heavy rain, strong winds, and the potential for severe weather. But first, enjoy two beautiful days—today and Wednesday offer lower humidity and cooler temperatures that won’t last long.
TODAY: Below Normal and Dry
Temperatures are noticeably cooler than typical for mid-June. The Upstate only reaches the upper 70s, the mountains settle in the mid-70s—about 5 to 10 degrees below normal thanks to high clouds. Humidity remains comfortable, making this an ideal day to tackle outdoor plans. Scattered showers move through the area, especially south of I-85 on and off throughout the day as a cold front lingers near the area push moisture just far enough north to make into our area.
It’s another pleasant night with lows in the mid 60s in the Upstate and the upper 50s in the mountains. It’s mostly cloudy and if you’re in the mountains, watch for patchy fog to form in the early morning.
WEDNESDAY: Warmer, Still Dry
Sunshine dominates. Temperatures rebound to near normal as a warm front lifts north across the area. Temperatures climb to the mid 80s. Winds remain relatively light out of the southwest, though some gusts reach around 20-25 mph during the afternoon. Clouds increase overnight as moisture begins to return from the south, and humidity climbs. Overnight lows jump the mid 60s to low 70s—noticeably warmer as humid air filters in.
⚠️ THURSDAY & FRIDAY: FIRST ALERT WEATHER DAYS
We are issuing First Alert Weather Days for Thursday and Friday as it looks like the time frame for the highest potential impact is Thursday night into Friday morning. There is still quite a bit of uncertainty with the intensity and the track of the system, however, we want you to be on alert for now and if the forecast improves, we’ll let give you the First Alert.
A tropical disturbance drifting northeast from the Gulf gets caught by a digging cold front pushing down from the northwest. The combination creates unusually windy conditions for this time of year—we’re talking sustained southwest winds around 17 mph with gusts around 25 to 35 mph, particularly in the afternoon.
Showers and thunderstorms develop during Thursday afternoon, becoming numerous by evening. Humidity soars as tropical moisture floods the region. Highs are in the mid to upper 80s.
Models disagree on exactly how strong the tropical system becomes and how quickly it tracks east. Some guidance shows a weaker disturbance tracking farther south. Others suggest a stronger system moving straight through our area or even an organized mess of storms barreling through Thursday night.
The takeaway? There’s a threat of heavy rainfall and stronger, damaging winds at some point between Thursday afternoon and Friday evening—we just can’t pin down the exact timing or intensity yet. Stay tuned for updates as this develops…
