GREENVILLE, S.C. (FOX Carolina) – Humidity builds Friday ahead of two First Alert Weather Days Saturday and Sunday. Scattered showers and storms increase through the weekend. Friday brings a typical late June day with highs in the mid 80s to right around 90. But the humidity starts to build back in which makes it feel more uncomfortable than previous days. We do have a chance for a few showers and storms after 10 AM in the mountains and after 1 PM in the Upstate. Isolated to widely scattered storms continue into the evening and early overnight hours before dying down into early Saturday.
