wxsniss Posted March 31, 2011 Share Posted March 31, 2011 Wow we really wiped out the boundary layer. Yes we did. And with ballistic omega possible overnight, I think Boston metro is in for a surprise... Link to comment Share on other sites More sharing options...
eduggs Posted March 31, 2011 Share Posted March 31, 2011 Visibility down to 3/4 mile in almost heavy snow. 33/ 32. Ground white and accumulation has commenced on everything except the road. Airmass does not support this observation based on temp and dewpoint temp alone. In fact, atmosphere is unsupportive at the surface for hundreds of miles. It's all about the dynamics associated with heavy precipitation. Evap cooling and any kind of horizontal advection not sufficient. But this ob is a great sign for most everyone.

HIPPYVALLEY Posted March 31, 2011 Share Posted March 31, 2011 Go heavy or go home....all the ledge jumpers from this afternoon are gonna look silly Yeah, that thread started to turn to the dark side of the force. I'm going to keep watching the radar and pressure falls hoping this thing amps up faster than modeled. Link to comment Share on other sites More sharing options...
40/70 Benchmark Posted March 31, 2011 Share Posted March 31, 2011 If I as forecasting for metro Boston there would have been no ledge jumping. Things back here just don't look good but it's possible we get lucky. Yea, you have a right to be worried...more speaking to ORH points east.

It has always looked like we see a surge of warmth from 775mb-850mb later tonight even up to BOS. BL issues weren't the big issues in this storm for many places which is unusual for an April snow.

eduggs Posted March 31, 2011 Share Posted March 31, 2011 You can get a dry air component on a E or NE wind while moisture is increasing from the south....thats actually how we managed to have an icestorm at 30-31F for 18 straight hours back in Dec 2008 without latently heating to 32.01. Maybe that isn't the cause right now, I'm not sure, but its certainly possible to get that. Completely agree. That's why I wanted to take a closer look... and from multiple obs in the region, does not appear to be the primary factor. Link to comment Share on other sites More sharing options...

CoastalWx Posted March 31, 2011 Share Posted March 31, 2011 Warm layer was very thin...only right near the ground....900mb temps and such were pretty cold Yeah that's awesome. I love how we can just wipe that out. Remember ysterday when we were in the mid 50s and I posted that the Chatham sounding was below -7C at 850? People always ask, "but how can it snow when it's so warm..". That's because it's so cold and dry aloft and we had a super-adiabatic atmosphere yesterday with the sunshine. I know you know this, but just so others know. Link to comment Share on other sites More sharing options...

wxsniss Posted March 31, 2011 Share Posted March 31, 2011 In case you missed it, 6pm AFD update out of BOX, reflects the trends observed on this thread in the past 2 hours: Near term /until 6 am Friday morning/... 6 PM...updated snowfall to bring some 1-3 inch amounts into rest of north CT...northwest Rhode Island and suburbs around bos /accumulations on grass/. Not yet confident enough to go any higher...but amounts may need to be nudged up a little more later this evening. Temperatures were dropping into middle to upper 30s due to wet bulb cooling which has forced a changeover to wet snow. Even had recent report of snow mixed with some rain in Falmouth Massachusetts. Changeover temperature seems to be around 37f. Temperatures should remain steady into this evening so we should have more snow vs rain across much of Rhode Island and eastern Massachusetts...which will slowly expand into rest of southern New England. Forecast has been updated to reflect this trend. Still looking at heaviest precipitation overnight. Link to comment Share on other sites More sharing options...

I'm a little surprised. I thought the significant temp drops at low elevations would hold off until the really intense stuff late tonight and tomorrow morning with less solar influence and a potentially greater lapse rate. I think this bodes well for a lot of the lower spots in eastern SNE. Of course the 850mb level could still warm later and ruin the party. Link to comment Share on other sites More sharing options...

The precip is coming down at a good rain on the coastal plain so it's not a huge shock. Back here in HFD where precip has been extremely light we are still all rain.
