eduggs Posted February 12, 2015 Share Posted February 12, 2015 Yup bout 40 miles or so on 7H and 5H low tracks.....(as it traverses SNE's longitude) The trajectory before it gets to this latitude is important. Link to comment Share on other sites More sharing options...

40/70 Benchmark Posted February 12, 2015 Author Share Posted February 12, 2015 Ya , Euro just grazed you lolqpf is always btr on outter edge than modeled. He'd be fine on euro Link to comment Share on other sites More sharing options...
SnowMan Posted February 12, 2015 Share Posted February 12, 2015 I think euro would be way better for you. Euro was better for you. Ya , Euro just grazed you lol lol my bad...based on the discussion it seemed like it was primarily a Boston / SE Mass focus area Link to comment Share on other sites More sharing options...
jamesnichols89 Posted February 12, 2015 Share Posted February 12, 2015 I did not see much of a tick with the upper level low positioning in its approach during the timeframe when it could significantly influence the outcome. After hrs 81 or 84 or so it does not really matter where the ULL goes because the SLP has already pulled NE. Both the 0z and 18z GFS tracked the ULL through NYS. Other guidance was further south. there was a huge difference in the QPF field this run. The H5 low was further south than 18z run and H7 low was as well.

OceanStWx Posted February 12, 2015 Share Posted February 12, 2015 That's some insane low level instability and lift on the GFS. Actually brings -LIs close to the MA coast. GFS cross-section you can actually see the theta-e lines fold over in the mid levels, from Barnstable to Lowell basically. Link to comment Share on other sites More sharing options...

jamesnichols89 Posted February 12, 2015 Share Posted February 12, 2015 I do not agree. How can you not see that, while the tick isn't considered extreme, it is still a tick to the south. Look at the difference in the QPF fields between the 18z run and the 00z run GFS. It is amazing. Link to comment Share on other sites More sharing options...

ORH_wxman Posted February 12, 2015 Share Posted February 12, 2015 H5 low looks a bit better consolidated this run on the GGEM...maybe it won;t be quite so inverted trough-ish. Link to comment Share on other sites More sharing options...
ncforecaster89 Posted February 12, 2015 Share Posted February 12, 2015 I usually use the tropical tidbits site for analyzing the models-specifically the ECMWF. Is there another one you guys find more preferable? Seems as though some of you get the updated panels a little more quickly than I do on there.

Seems as though some of you get the updated panels a little more quickly than I do on there. instantweathermaps.com is what I use to get the GFS and NAM quickly, and I use weatherbell(It's $20 a month, but well worth it IMO) for the other models(including the Euro) and for more detailed analysis of the GFS/NAM because their graphics are much better and you can get zoomed in views which are critical for details.
