Be safe brother. Seems like 430 is the new commute time. Any later and it sucks Link to comment Share on other sites More sharing options...
87storms Posted December 16, 2019 Share Posted December 16, 2019 pretty decent moisture fetch: https://www.star.nesdis.noaa.gov/GOES/conus_band.php?sat=G16&band=08&length=12 gotta fight some dry air, but all systems go for the first legitimate light snow of the season.

snowfan Posted December 16, 2019 Share Posted December 16, 2019 0Z NAMs not exactly a great output for anyone sans extreme N/W. Dry slotted by 12Z and directs the secondary push of moisture north into PA. Link to comment Share on other sites More sharing options...

Nams max my yard right around 32 tomorrow. Even the Euro gets us no higher than the mid 30's and that isn't until Tuesday afternoon while the GFS gets near 50. Down to 30 here now.

clskinsfan Posted December 16, 2019 Share Posted December 16, 2019 12K NAM is interesting. Showing a pretty decent ice event for NW of the cities tomorrow evening. Would be cool to get some crust on top of the snow before the rain hits. Link to comment Share on other sites More sharing options...

WxUSAF Posted December 16, 2019 Share Posted December 16, 2019 IAD 0z sounding had wet bulbs below freezing through the entire column except maybe right at surface. Low levels are dry.

If I squinted hard enough I could see a spurt or two but mostly nothing. Sitting at 36F Link to comment Share on other sites More sharing options...

WinterWxLuvr Posted December 16, 2019 Share Posted December 16, 2019 Sometimes precip can overcome the dry air very quickly. The Jan 2010 storm is an example. It was about 15 degrees with a dewpoint of 4 and when the first echo appeared overhead we had snow flakes falling. Link to comment Share on other sites More sharing options...

And then sometimes you get flurries for 10 minutes and the sky just opens up. Hope it starts sooner than later. I am ready for my first Jebwalk of the year.
