At one point this afternoon both Thermal and Palm Springs stood at 3% relative humidity. Anybody got a glass of water?
You can’t have zero relative humidity. It was just low enough to round down to zero. When the air is that dry, measuring dew point accurately becomes difficult.
This seemed like a good day to find a graphic and compare “feels like” temperatures in the desert with Georgia/South Carolina/Florida. It was hotter in the desert, but not by much.
The manifestation of all this heat and no humidity is enhanced fire danger. A ‘small’ fire broke out near Thermal. A much larger fire is burning in the San Bernardino Mountains near Big Bear.
California is full of wilderness. Fires like these are very difficult to extinguish, even with the science and technology we’ve brought to bear over the last few decades. Fire season has just begun.
