MN Transplant Posted March 3, 2013 Share Posted March 3, 2013 #2 is Feb 7 1980 #1 is April 4 1998 (which I dont remember at all) Neither are interesting. #4 is 2-4-95 which was a 4.5" storm at DCA. Link to comment Share on other sites More sharing options...
Amped Posted March 3, 2013 Share Posted March 3, 2013 um 21z SREF turns us to rain. Probably a back end dump if they went out past 84 Link to comment Share on other sites More sharing options...
Bob Chill Posted March 3, 2013 Share Posted March 3, 2013 Wow those analogs are enormous. We need that block to stay right where it is now. We dont want that 500 going a lot further north. SR models will have a tendency go a little nuts amping at the end of their runs. Zero reason to be remotely concerned until the globals do it. Were still at least a day away from worrying about nam/sref. Link to comment Share on other sites More sharing options...
mitchnick Posted March 3, 2013 Share Posted March 3, 2013 Neither are interesting. #4 is 2-4-95 which was a 4.5" storm at DCA. that started as rain at BWI but quickly turned to snow man I wish we had some cold air to tap maybe some of that -60F stuff that's over the Pole right now makes it here in time!

thunderman Posted March 3, 2013 Share Posted March 3, 2013 the path of the 5H vort is looking similar to 2/10/10, but w/o the cold temps just sayin' Feb '10 is #3 on CIPS Link to comment Share on other sites More sharing options...
mitchnick Posted March 3, 2013 Share Posted March 3, 2013 um 21z SREF turns us to rain. Probably a back end dump if they went out past 84 all the models have rain along I95 for at least part of the storm, so I don't think that really changes any thinking re the storm we need some cold air or this will be the most anticlimactic heavy rain/snow mix ever to fall in our area Link to comment Share on other sites More sharing options...

Stronger H5 low tracking further north is probably aiding this. A back end dump will be hard to miss because the H5 low still goes south of us. Based on the srefs I'd also say suppressed like last nights GFS is off the table. Link to comment Share on other sites More sharing options...

mitchnick Posted March 3, 2013 Share Posted March 3, 2013 SREFs have sucked all year, but they have not been bad with this potential event so far, at least wrt 5h path vs. other more reliable models that is Link to comment Share on other sites More sharing options...

Ian Posted March 3, 2013 Share Posted March 3, 2013 Was thinking 2/10/10 a bit earlier as well tho that vort entered quite a bit east I think. Good to see some fun CIPS analogs. Now we hope and pray it holds another 24 or so. La la lock it up. Link to comment Share on other sites More sharing options...
Bob Chill Posted March 3, 2013 Share Posted March 3, 2013 a kitten dies every time a weenie uses the 87hr SREF mean to forecast p-type I'm a major weenie but I do stick to a set if rules when making sense of a zillion pieces of model info leading up. We aren't even at the point of looking past global ens means. Using end of run Sref/nam at this range for deterministic stuff will make a sane person insane.

mitchnick Posted March 3, 2013 Share Posted March 3, 2013 I honestly was over this winter and expected nothing more if this storm happens, great if it doesn't, I frankly don't feel like I've lost a thing because this winter was dead already Link to comment Share on other sites More sharing options...

Just smooth out based on interpolations of good data, or do they take the 6hr forecast from the previous run in to account? there is a background field which I believe is taken from the previous run, radiosondes only make up a small portion of the observations that are assimilated each cycle and its entirely normal to have several issues with them.

I know a lot comes from satellite data, but I thought actual rawinsonde obs were pretty important. Why is it if satellite data is the majority of obs does it matter when shortwaves are over the pacific for sampling? Link to comment Share on other sites More sharing options...
