Interesting UHI experience this afternoon. Left Tyson’s headed to Annapolis around 4:00. Snowing pretty good. Snowed all the way down GW Parkway but began to taper off as I crossed Roosevelt bridge. Once into the city, boom, snow cut off. No snow at all as I made my way through heart of downtown in North West. As I hit NY Avenue, now in North East, snow gradually came back. Not like in NOVA but there. Thought it interesting that even though further East than heart of downtown, the UHI impact of downtown won the day.
