Eskimo Joe Posted July 17, 2017 Share Posted July 17, 2017 Impressive outflow from that Takoma Park cell...you can see it extending out through Kensington and Bethesda...heck it might even make it to Glen Echo.

All three radars are pretty far away, but they all have estimates of 4"+ in the small area north of York. Unfortunately the only good personal weather station there seems to be malfunctioning.

BlizzardNole Posted July 17, 2017 Share Posted July 17, 2017 Wow. Big, heavy thundershower developing almost in place just a handful of miles east of my dusty, parched location. It's not just how often we miss out on rain - it's how close it typically is. What a desert micro climate. Link to comment Share on other sites More sharing options...
