True, it has siting issues, but BWI is far enough removed from UHI of the immediate downtown (not to mention the less important 47 m ASL elevation) and is as representative of that area as Dulles is representative of the National Mall. Come to think of it, BWI actually has cooler highs than PHL in August and September.

So are DCA and quite a few other official stations (PHL, Central Park, BOS, to name a few)...

At least those stations are slightly removed from the center of downtown, though I do think DCA in particular is a terrible place to measure snowfall. Equating those places with the Inner Harbor is fallacious and stupid.

Dulles is quite a bit further from DC than BWI is from Baltimore.

Nowhere did I suggest that they are exact equivalents, so good work mis-representing my words DCA's snow totals are deflated largely due to the automated snow measurements, and much less so siting, unless you can demonstrate winds off the Potomac during snow events either increase temperatures appreciably or slash snow-to-liquid-precip ratios. It is no Tenleytown, sure, but apart from The Eclipse + Mall, hardly any area in the District is both far-enough removed from buildings AND still relevant to the downtown (e.g. Rock Creek Park and Natl Arboretum are not)

Dulles is known to be located in a cold spot in NoVA; BWI's normal January low (24.4 F) is only 0.5 F higher than that of Dulles (23.9 F) despite having around half the altitude and, more importantly, proximity to the coast. Its normal lows are also at least as low as those of Wilmington, DE. Smacks of a cold spot to me.
