Cold to warm: Dulles made it to 75 today. Impressive on its own in November, but consider the low was 35 this morning. Yep, a 40-degree rise in temperature. This is partly thanks to dry air near the ground, which is able to warm quickly. There was also a temperature inversion, where warm air was sitting on top of very shallow cold air. As the sun rose and some wind kicked up, the warmer air quickly “mixed” down to aid in the warmth. Other places on the East Coast also saw huge temperature spreads today.
