EastCoast NPZ Posted February 16, 2015 Share Posted February 16, 2015 snow has become heavier. i'd say we're pushing 1/4" on the ground now. Link to comment Share on other sites More sharing options...
chris87 Posted February 16, 2015 Share Posted February 16, 2015 HRRR was wretched on Saturday FWIW. i'm really not sure what's causing the drying we've seen in the HRRR runs towards this evening -- doesn't really show up much in any of the regional/global models -- it's not like we have a super strong high pressure feeding dry air into the region (at least not to my knowledge).

EastCoast NPZ Posted February 16, 2015 Share Posted February 16, 2015 Over to dendrites now. Light snow everything covered including the roads. The snow is laughing at the salt on the roads at 16 degrees. Yeah, I can't tell if they're dendrites or not, but they have certainly increased in size. looking nice out there now.

That's a good point Chris...there isn't a super high feeding in. In theory the storm flow should take over with the weak high moving off. If we keep our flow e to ne we should be good to go.

Crystal City Jeff Posted February 16, 2015 Share Posted February 16, 2015 Pixie dust has commenced in Annandale, VA ... 16 ... dew point 4 Link to comment Share on other sites More sharing options...
Eskimo Joe Posted February 16, 2015 Share Posted February 16, 2015 For DC Metro folks, the magic number for the dew points seems to be -2. All the AWOS/ASOS started showing snow once they rose above that number it seems. Link to comment Share on other sites More sharing options...
WEATHER53 Posted February 16, 2015 Share Posted February 16, 2015 Looks like a, if not The, center of circulation going over or just north of Atlanta which is perfection. See the mixing line, there will be surprise juice with this. Moisture that wants to mix running into -5 dewpoints will be awesome. Link to comment Share on other sites More sharing options...

clskinsfan Posted February 16, 2015 Share Posted February 16, 2015 Yeah, I can't tell if they're dendrites or not, but they have certainly increased in size. looking nice out there now. Yep. Not snowing hard by any means. But if it keeps up at this pace for 16 hours. its gonna be a decent event. Link to comment Share on other sites More sharing options...
Stormpc Posted February 16, 2015 Share Posted February 16, 2015 Almost moderate snow now. All area roads have caved. Salt not doing anything. Gonna have to wait till we get 2-3 inches then break out the plows. Salt ain't going to do it with 14 degrees with ice cold ground. Saturday, VDOT had trucks waiting all over the area roads and lots hours and hours before anything fell. Now, I could not find a truck anywhere. I bet the start time the NWS was giving threw them off a bit. Been snowing over an hour now. Last 30 minutes of any consequence. 14.5. Link to comment Share on other sites More sharing options...

Not really my thing to explain, or justify, it to you as you should already know this. Moisture laden air that is moist enough to try and mix running into below zero dewpoints will provide for a dynamic situation. Link to comment Share on other sites More sharing options...
