Compared to the last several weeks, we experienced a heat wave today. Temperatures were in the 40's with some moderate rain. As a result of the warm air moving in and the rainfall, the fog developed very quick. By 3pm, visibility was very low. Likely less than 1/4 mile. However, by 7pm skies began to clear and the fog began to lift. The current temperature is around 35 degrees, but the temperatures is supposed to drop to 25 tonight. If there are areas with fog left over, it will become freezing fog.
