That is just synoptic/FGEN/lake enhancement. Any pure LES from Sat/Sun is not included...and that likely will be several inches. .
-
The 6z RGEM is north again too. 1001mb SLP around Joplin at 48hr, with 500mb closed off around Topeka. .
-
Significant LE snow post-storm for Chicago, for over 24hrs. There’s also enhancement during the storm. .
-
What a run... .
-
Big changes again, in a positive way. Southern trough ends up going neutral tilt earlier yet again, and this run closed off 500mb over C. Kansas by 51hr. Slower a bit as you mentioned, do the the aforementioned. .
-
Grasping straws instance, but the long range RAP is even further north with the trough as ejects out into the Plains and is more neutral tilt earlier. SLP is way up in S. Kansas. Edit: Might have to click to loop.
-
0z EMCWF did come in further north and more neutral tilt with the trough coming into the Plains...But outside of that SLP pushes fairly east.
-
You're forgetting the November blizzard.
-
0z GEFS came in a bit south/drier.
-
For that time-frame, yes...but before that it is identical, and after that it's actually a bit south. Seems like it started to push ENE, then got shunted east, as did the trough...similar to the GGEM
-
Globals vs Hi-Res...We've seen this battle before, but it's been a while.
-
0z FV actually came in a bit south aloft and with precip, but around the same for the SLP.
-
FV is coming in further north with the wave coming into the West Coast.
-
Very odd overall. The trough out west was so far north of 12z, then it just got kicked east. Haven't looked into it, but I'm guessing lack of phasing or some other reason.
-
Eventually ended up further SE across the OV. Had some issues aloft...
-
0z GGEM taking a good jump north. Trough much further north out West and entering the Plains.
-
0z GFS is very similar to the 18z run overall.
-
Let's just say the 18z run had a 997mb SLP in N. AL at one point, which was actually south of 12z run at that time.
-
Barely. It was pitiful compared to any other 18/0z run.
-
If you think the 0z NAM is north, try the 0z RGEM... It only goes to 48hrs, but it has a 999mb SLP over OKC at 48hr. The NAM is ~1003MB near Fredrick, OK along the Red River.
-
One big observation on the 0z NAM is that the following wave crashing into the PAC NW is actually helping lower heights with the Western ridge. This might help kick our the southern trough, possibly northeast a bit eventually.
-
NAM is going to be well north, many factors in play.
-
NAM definitely going to be better and probably north. Southern wave is stronger, neutral tilt trough sooner, more ridging over Midwest/OV and less ridging over Western states earlier.
-
0z NAM is coming in north with the southern wave entering the West Coast once again.
-
Nice jump from previous runs in earlier hours. There's actually a greater number of them above the mean as well. They also have a period of 1-4"/hr snowfall rates Friday night/Saturday morning. The mean is closer to 1-2"/hr.
