18z EPS mean
-
Moisture laden for sure, with both a Pac and Gulf connection.
-
18z Euro thru 12z Thur...
-
18z GEM was about the same with overrunning, but was definitely going to be north with the main storm system.
-
Definitely higher for the main storm system. Several posts back I posted a Chicago metro sounding from during the heart of the storm on Thursday, showing a deep DGZ.
-
A few appear to be near ~40” based on WxBell maps color scale. Obviously at 10:1 ratio. .
-
Sounding from the Chicago metro on Thursday, during the heart of the main storm system. Deep DGZ is deep.
-
There might have been some potential still left on the table with that trough evolution in the Southwest/Plains. .
-
18z GFS is coming north with everything... Overrunning event and the main storm system.
-
all of the OG regulars are back. need an amped NAM run to bring the WI folks out of hiding. .
-
just keep it easy as GHD III
-
12z Euro is going to be wayyy north with the main storm. Significant changes aloft in terms of trough organization/quality, ejection timing and ridging ahead of it.
-
Main storm should be north... Far less positive tilt and a bit faster as well.
-
In the end, yea it does look like that. Seems like most 12z guidance made that transition to different degrees.
-
12z Euro is going to bump the overrunning event south.
-
12z GEPS .
-
12z GEM .
-
12z GEM is a bit south with the overrunning event and is well south/weaker with the main storm (Ejecting trough is much more positive tilt/strung out/further south).
-
Main storm is a bit north of previous run. More ridging ahead of the ejecting trough, however it was slower.
-
We have a few STL area posters in here.
-
12z GFS coming in with a slightly different orientation for the overrunning event...It's a bit south for eastern areas and a bit north for western areas.
-
12z RGEM bumped north with the overrunning event, and then would be a good bit north with the main storm system.
-
12z NAM has a slightly different alignment for the overrunning event, and then definitely will be further north with the main storm.
-
Differences in the 12z NAM start off at noise level early in the run, but increased quickly by mid-run. Main storm is definitely jumping north on this run.
-
A lot of guidance that is south of the GFS are still showing significant snowfall totals. I’m not saying it’ll be the case with this one, but there are many cases that would prove the first part of your comment wrong. .
