Usually "the early bird gets the worm" at DC, i.e. the wind is strongest and steadiest shortly after it comes up. Not yesterday! It just kept increasing, and while never exactly steady, it did seem to get a bit steadiER as the afternoon and evening progressed. It didn't hit its peak until 9 PM, backed off until 3 AM, and then started building again. Gusting into the low 20's right now.
