I was driving to work this morning and experienced a strange phenomenon. While barreling down the toll road at ~74mph, the windows on my car fogged-up to 0-visibility levels. All the outside surfaces, including the mirrors, were covered in condensation within a matter of ~5 seconds. At first I thought it was just a waft of smoke from my kretek, but then it thickened and covered with surprising speed and determination.
I was able to hit the wipers and clear the forward view, but I couldn’t see anything else. Sure, I could roll-down the windows, but I couldn’t clear the rear window or side-views. This made lane-changing almost impossible to execute with any confidence. It began to dissipate after a minute or two, and all was gone within 5.
What just happened? I didn’t see any fog, so I assume I hit a patch of super-saturated air, though I’m interested in any meteorological specifics.
Current conditions and details.
Generally, the morning conditions were ~55F, low ceiling but no fog, one (~1.5 miles) patch of drizzle.
METARS for the area at the time (I was never more than 8-12 miles from the reporting station).
I was driving from about 13:45Z for 30 minutes (08:45 – 09:15 EST).
I had the heat selected (floor vents), temp just barely on the hot side of the mid point. A/C compressor on.
