Bob Chill Posted February 22, 2018 Share Posted February 22, 2018 I think we can all agree that the GFS didn't nail jack sheet this run. But it opened the door for some discussion as we waste time getting rained on. Link to comment Share on other sites More sharing options...

But Day 7-10 it's tracking a system east to west north of us lol. Some crazy stuff showing up. Gfs has weak systems moving north to south down the coast. Everything is pinwheeling around stuck under the blocking. CMC does have a weak storm but for SNE Link to comment Share on other sites More sharing options...

Did you see how the storm that starts over Chicago ends up off the mid Atlantic then retrogrades SW towards the Bahamas after that. Lol. Crazy crazy. Unfortunately might be too crazy. It's showing up on all the guidance. The initial wave in a blocking regime is rarely the one. Typically that establishes the colder air. Then after is when we have shots. But this blocking might be too extreme. It's setting up what typically happens to our northeast over us. With a big pinwheel under the block. But nothing can amplify in that. It would just be days of chilly breezy snow showery weather. Maybe some discreet vorts embedded with minor events. But that has to relax. If this fails my money is it's because of too much blocking and suppression after that initial wave around March 2. Link to comment Share on other sites More sharing options...

Actually...it did exactly what chuck said it would do lol. It did this one op run about a day ago also. Instead of retrograding the block west across Canada it retrogrades south and merges with the ridging over the CONUS. That's a total disaster. It's so extreme it ends up simply becoming a mid latitude ridge instead of blocking. But 99% of guidance as yet doesn't support so unless we see things move that way I'm not worried.

If this fails my money is it's because of too much blocking and suppression after that initial wave around March 2. My thoughts exactly. The EPS was suggestive of the possibility when we saw the 50/50 displaced so far south earlier in the extended. Didn't like the look, And the look later in the extended was so ambiguous with the blocking and 50/50 it was hard to tell where it favored those features setting up. 14 minutes ago, C.A.P.E. said: LOL the GFS just lost the block. It like..evaporated. Looking at the ensembles in the extended I got the impression that the members were warring over the high latitude blocking or lack there of so it comes as no surprise to see the Op lose it. Think we will really need to see that period get much closer in range to have an idea what we will be dealing with. Anything past day 10 is going to basically be a crap shoot.

psuhoffman Posted February 22, 2018 Share Posted February 22, 2018 Mjo doesn't really support eastern ridging either. We seem headed into cold phases. I don't worship at the mjo alter but this year our temp anomalies have lined up with the mjo waves. Some years that isn't true but it has been lately.

Yeah I noticed the tendency to break it down some too- towards day 15. The 12z GFS basically has a transient GL ridge of a few days, not really a block at all. It is almost always interesting with the op beyond day....3. lol. Link to comment Share on other sites More sharing options...

showmethesnow Posted February 22, 2018 Share Posted February 22, 2018 GEFS still shows promise centered on day 8. Players are still on the board with some minor differences. Snowfall mean has ticked up once again through that period especially around the PA line. Link to comment Share on other sites More sharing options...

Slight improvement overall in the snowfall mean for the region (over 6z) through the end of the run. More so for south-central PA. Link to comment Share on other sites More sharing options...

Sometimes in march blocking these systems that come in west to east with initially warm or a nw tracks can go nuts once they get off the coast. It's been a while but there are lots of examples mostly from the 50s and 60s when we had a lot of late season -nao. It's been rare since. But it's been on the back of my mind maybe this starts off a mess then something bombs off the mid Atlantic coast. Link to comment Share on other sites More sharing options...

psuhoffman Posted February 22, 2018 Share Posted February 22, 2018 Not surprisingly the gefs doesn't support the op gfs idea of sliding nao ridge all the way south and merging with the mid latitude ridge. It retrogrades it west then actually builds it back into Greenland towards Day 16. Given the group think issues when the gefs disagrees it's a pretty good indication the op is smoking some funky stuff. Link to comment Share on other sites More sharing options...

Evolution of the block is a bit different after initial retrograde but it persists on both. CFS weeklies still look solid. Link to comment Share on other sites More sharing options...
