Temperature at National Harbor has gone up one degree in the last hour, 34 to 35. Dewpoint 32.

Looks like the DC snow hole may be in play. Even though the NAM is showing the coastal low juicing up, the changeover from the dominant low in the west to the coastal low might dry slot us. I hope my interpretation is wrong. I'm looking forward to a little white on the ground come sunrise.

probably just my weenie eyes and pathetic last minute gasping, but I'm noticing on sat and water vapor banding starting to appear in eastern NC

you can sort of see it on this sat loop and the water vapor loop below that

meanwhile, rain is developing in eastern NC

I don't see any stations reporting rain yet, but it's showing up on the Wilmington and Raleigh, NC radars

http://radar.weather.gov/radar.php?product=N0R&rid=mhx&loop=yes

in the past, some decent/strong storms have had that banding show up in sat and wv pics

because the ncep site is screwed up, I don;t know if the NAM had this though thru the first 6 hrs of the NAM, it shows no precip

this could all be just as planned by the computers, but just noting it seems seems odd....time will tell

Wes.. you were posting!

I was but am not really excited enough to post anything of note. I was going to show that the GFS forecast sounding for IAD was actually colder than the observed at 00Z but then thought that it didn't matter as I'm not sure it matters. I think we eastern guys may have already pretty much bottomed out in terms of temps and will probably rise a little during the night with the southeast winds even though they are light though we may drop some from evaporation when the precip first starts. The faster the precip gets to us the better and the harder it falls the better.

I don't see you Matt or I getting an inch. I thought the Kammerer's forecast was a pretty good one. That's why I'm blase about the storm. Plus, the vort seems to go north of us while the weak southern low passes south and doesn't get its act together until it's by us which suggests precipitation will probably be on the light side (famous last words). Hope I'm wrong.
