The signal is clearly there for a storm, anything other then that right now is noise. Expand But we had the signal for a storm across all modeling last year and then it went poof inside 5 days. That possibility has to be on the table at this point. Not saying it will happen or that this pattern isn't a good one... Link to comment Share on other sites More sharing options...
Scraff Posted December 2, 2018 Share Posted December 2, 2018 I slept in this morning. Woke up to a roller coaster in here. Probably going to be that way for another day or two before we can safely lock in win or fail. Of course, JI will wake up shortly and cancel the rest of winter. Maybe even next winter.

luckyamaha Posted December 2, 2018 Share Posted December 2, 2018 I was up all night since I work nights so it looked good with the Euro then 6z sucked on GFS. Now time for sleep so keep the ball rolling but not suppressed for next runSent from my moto z3 using Tapatalk Link to comment Share on other sites More sharing options...

Expand Correct. We went from an 18z cutter to a 6z suppessor...in 12hours. If your going to parse through every op run (and I do....and i enjoy it), one can only can look for trends and general storm track w/ op runs at this lead.

MillvilleWx Posted December 2, 2018 Share Posted December 2, 2018 Something that will need to be watched closely is the strength of the forecasted confluence to the north. There's been times in the past where the medium range confluence pattern is progged too strong initially, which is why some storms tend to draw north as we inch closer to prime time. Also, a slightly more energized southern wave is still possible as is something else we've seen adjust in the short term. There's still so much time with multiple moving pieces to sort out, there's no way anyone should be gunning on any one particular outcome. Now, ensemble trends were a bit more boo than bite last night with the general strength in the confluence to the north, but mid-week will be the time frame where models will start getting a better handle of both pieces. If ensembles are squashing the southern wave by Wednesday still, then it's likely the region will have a hard time getting a worthy event. There's not much change that needs to occur for this to trend better. Link to comment Share on other sites More sharing options...

caviman2201 Posted December 2, 2018 Share Posted December 2, 2018 Is there even an analog this early in the season for a suppressed STJ wave that dumps on the Carolinas while we get nada? I have to think we have climo strongly on our side here too. Even if it is within the realm of possibilities, I have to think a solution like the 6z GFSv2 is exceedingly rare this early in the year.

Expand Very true. Climo and calendar just don't support this thing getting squashed. If it's suppressed, it's probably due to the shortwave ending up drastically weaker rather than cold air pushing it to FL. Link to comment Share on other sites More sharing options...

There isn't much history or support for major suppression for this storm, and climo says its a little early for suppression.

Last night's EPS had the confluence stronger north, which should have supported a north trend on the low placement. The fact that it went south a bit was due to the s/w being weaker and counteracting that shift in the north. Link to comment Share on other sites More sharing options...

Expand Is SW strength something we generally have to wait until it comes onshore to determine or are satellites able to reliably pick that up and feed it to the models while it's still over the ocean? In other words at what point is the initial SW strength "locked in"? Link to comment Share on other sites More sharing options...

Guidance can give a fake signal that it makes a difference but the real reason is by the time shortwaves on onshore, the lead time is shorter and it's normal for models to shift at shorter leads.

WesternFringe Posted December 2, 2018 Share Posted December 2, 2018 The high at 144 (in Wisconsin) on the 12Z GFS is modeled further N than the high at 150 on the 06Z GFS. Should give it more room to move north....hopefully Link to comment Share on other sites More sharing options...

How much it gets sheared, whether any more energy phases in, etc. Expand I've seen countless instances where a jet was not initialized properly until it was sampled on the West Coast...specifically while living and forecasting in the Midwest. Because of the way models are initialized, there is rarely going to be an instantaneous change in the modeling given new obs, which is why the trends are important to watch. I am curious to see whether the introduction of higher-res GOES-16 and GOES-17 data changes this. Link to comment Share on other sites More sharing options...
