Thunder Road Posted January 26, 2011 Share Posted January 26, 2011 is that 20-50mm to the RGEM? Sounds good to me. When do the color charts start updating? Link to comment Share on other sites More sharing options...

Parsley Posted January 26, 2011 Share Posted January 26, 2011 RGEM very sharp cutoff on the QPF once north and west of I-78. Looks like 0.50-1.00 total south/east of there in PA. Guesstimating around 0.75-0.85" here near PTW, Link to comment Share on other sites More sharing options...

tombo82685 Posted January 26, 2011 Share Posted January 26, 2011 is that 20-50mm to the RGEM? Sounds good to me. When do the color charts start updating? prob within the next 15 mins...for phl it looks like atleast 20mm or about .8 qpf. Link to comment Share on other sites More sharing options...

Thunder Road Posted January 26, 2011 Share Posted January 26, 2011 prob within the next 15 mins...for phl it looks like atleast 20mm or about .8 qpf. yeah those b&w charts have huge ranges, but a low end 0.8 is very nice. if i recall correctly, last friday's event the RGEM was a bit too high with QPF while the NAM's was a bit too low. I wonder if the RGEM has any known wet bias, or if that was just a coincidence. Link to comment Share on other sites More sharing options...

hstorm Posted January 26, 2011 Share Posted January 26, 2011 Glenn says he may need to move his totals more towards South Jersey. He indicated that his statement was based "on the most recent guidance," presumably the 0z NAM. He also indicated that he wanted to see the entire model suite before making any changes. A very reasonable position. His snow map showed 5-8" for PHL and vicinity. More towards the NE (I think, 6-12"). Link to comment Share on other sites More sharing options...
tombo82685 Posted January 26, 2011 Share Posted January 26, 2011 here the color maps, the rgem actually brings in a good slug within first 12 hrs then the main show Link to comment Share on other sites More sharing options...
Billabong Posted January 26, 2011 Share Posted January 26, 2011 We really need to watch this front band. It's probably going to catch many off guard. All the people I spoke to are not expecting any snow until later on in the afternoon. I can see this band moving over the PA border around 4am or so and dumping a nice 1-2" of snow in the area to make for a slippery commute. Link to comment Share on other sites More sharing options...

Parsley Posted January 26, 2011 Share Posted January 26, 2011 Damn that is a nice looking deform band on the RGEM. Yeah I think extreme SE PA is really setting up nicely for this event. Not max QPF's but little or no mixing at the onset. Link to comment Share on other sites More sharing options...

Thunder Road Posted January 26, 2011 Share Posted January 26, 2011 Has anyone been checking the HRRR? It nails SEPA with that band tomorrow morning from 5-9am, drops 2-3" area-wide: I've been following it for several of the past storms and it seems to do well each time, but I'm rather skeptical this time. That means that morning commute goes to hell fast if this verifies. Link to comment Share on other sites More sharing options...

jrodd321 Posted January 26, 2011 Share Posted January 26, 2011 it should be noted that is water equivalent of snow SACRUS said to divide by 2.5 so that path that goes through philly is 8-12" Link to comment Share on other sites More sharing options...

jrodd321 Posted January 26, 2011 Share Posted January 26, 2011 GFS looks west at 18? Yea looks like it's trying to give us a nice quick thump on the onset with that first band that tombo was talking about the RGEM having too. Link to comment Share on other sites More sharing options...

Voyager Posted January 26, 2011 Share Posted January 26, 2011 that cutoff is oh so close in NW NJ still. Argh! That cut-off really hasn't budged. It sets up in the exact same place in the same orientation model after model after model. Here in PA, it's like the Blue Mountain is the snow gods' Berlin Wall.

Thunder Road Posted January 26, 2011 Share Posted January 26, 2011 0.75-1.00 south/east of 202 through hr30. still looks very nice. Edit: that's a rough estimation of where it sets up, though. at 06z 1.00" is just about in to philly. let's see if squeeze out a few more hundredths at hr 36...
