87storms Posted December 22, 2022 Share Posted December 22, 2022 It's downright chilly up here in Frederick right now. These are times when I don't miss living in Bethesda lol. My elevation isn't too great here (300-400 ft), but it jumps quickly towards Gambrill State Park which I can basically ride my bike to. Long story short, tomorrow morning is getting interesting even for the immediate DC 'burbs. Link to comment Share on other sites More sharing options...

It won’t be great but a lot better then what I’m gonna prob see in Baltimore county . Link to comment Share on other sites More sharing options...
WVclimo Posted December 22, 2022 Share Posted December 22, 2022 With skies still mostly clear, I’ve dropped to 26° with the DP at 15. My location typically does very well with radiational cooling. Working it’s magic so far this evening. 1 Link to comment Share on other sites More sharing options...
AtlanticWx Posted December 22, 2022 Share Posted December 22, 2022 temps seem to be running colder than forecasted and each subsequent HRRR is trending colder; don't wanna sound like a weenie but perhaps an overperformer W of I95? hrrr now has snow bursting across moco 1 Link to comment Share on other sites More sharing options...

Temps look pretty chilly throughout the region with the CAD in place. If there's going to be an overperformer (at least temporarily), this has some of those vibes. 1 Link to comment Share on other sites More sharing options...

That’s like a 7 degree drop in temp if precip came in right now. More like a 5 degree drop, but definitely works. I've learned over the years that THE MINIMUM you should go with when meeting temp to DP is 3 DP's up for each degree down in temp. That has saved a lot of heartache over the years. 2 Link to comment Share on other sites More sharing options...

The fall line in the recent run appears just west of my house. Probably once you gain elevation after passing Leesburg you’d see something. 1 Link to comment Share on other sites More sharing options...

Terpeast Posted December 22, 2022 Share Posted December 22, 2022 If going by the 3:1 dp/temp adjustment to wet bulb temp, IAD currently at 36/24 will meet at 33 at saturation. Rain. Could get colder with more CAD, but not with a light wind from the SE. Link to comment Share on other sites More sharing options...

rjvanals Posted December 22, 2022 Share Posted December 22, 2022 Problem for immediate NW crew will be temps from 1500-3000ft looking at soundings. Hopefully they’re running a degree or two warm. Link to comment Share on other sites More sharing options...
