     The Gulf looks somewhat active (more active than most of the season so far) overall on the 12Z models so far. However, the UKMET, which goes out only 168, did drop the Gulf TC per its textual output that it had on its prior 2 runs.

    Looking at the recent guidance, if I were going to highlight some areas of interest it would be the Gulf/SE Coast in the next week, the western Caribbean with a weak CAG signal in the 7-10 day period, and a tropical wave in the MDR in that same period. It looks pretty active--or at least there will be chances for TC genesis. Might do a post later about it. 

    I track my peak season forecast numbers in the legacy Mid-Atlantic thread, but I'll post here too. Imelda likely gets me to 3 H or 50% of my forecast with three full weeks left (including today). It has an outside shot at MH, which may all but guarantee that I am too low on MH as I expect at least high end activity in October. 

    Unfortunately for coastal residents, I still think a MH strike is likely, and that the east coast isn't out of the woods on threats. I'm not sure what to think about Imelda's threat to the coast--if not for Humberto going nuclear, I think this would've been the EC hurricane strike I predicted. For the east coast that definitely gets less likely in October though as the images I posted above show, that's really after the 10th.

  2. Should've posted this yesterday but it actually makes more sense today as Imelda is on an intensification trend. Imelda adds to the list and should become a hurricane. Outside shot at a major. The peak season forecast is still up in the air, but with activity still expected on the models and in the areas I highlighted, I like where I sit.

    Honestly this storm had organized at a quick pace overnight with pressure falls and a the center under the CDO. Think pace of intensification quickens through the day 

    The ragged eyewall does look like it collapsed per recon, but that's not really a surprise given IR last night. I do agree that the presentation has really improved and the pressure falls have been impressive.

    Absolutely not. Maybe it performed well for this one event, but that doesn't mean it's better than traditional NWP. You really need to conduct a thorough evaluation at the surface and aloft (for forcing variables) to make such conclusions.

    As an example, it's possible something can be right for the wrong reason. You wouldn't know unless you evaluated it... So, if AI did well with forcing, wrt NWP, over a duration of 1 year, then you can entertain the idea. This is just imo, but we're years, if not decades, away from this. We likely need to significantly improve data assimilation for this to occur.

    Agree with this. I will say that some of the AI models earned a little more respect with me this season, but to your point--it's going to take time to truly get a sense of how well it analyzes critical forecasting factors over the long term. Every forecast is different and every TC is a distinct entity. 

    And at any rate...models are merely tools. So us laypeople should beware relying on any one as gospel in any situation. (not saying that anyone here is necessarily doing that)

     

  5. The wind field is still not particularly organized or strong, but the winds are gradually coming up as the satellite presentation continues to improve.

    The center is now under a developing CDO, with persistent deep convection we should see the pace of organization pick up over the course of the day. The pressure has continued to fall, with the latest center dropsonde showing a possible pressure below 990mb now.

    Yea, obviously the point isn't to expect a record winter, but rather we shouldn't be resigned to another dud because the year has been dry thus far.

    I hope so. I haven’t done too much thinking about winter yet but it’s less that it’s been dry thus far in my mind and more the background state of warm seasons and worse, that it seems our results are untethered from patterns that normally would be good to great for us. That concerns me. Like @CoastalWx, I’ve totally lost faith after the last decade.

     The 0Z UKMET (a model that tends to be a bit more stingy with TCG than the GFS) is the 2nd run in a row that develops a TC from the current C Gulf weak surface low after it moves S into the Bay of Campeche. This run actually has minimal TS winds early on. Whereas the prior run then moved it into a threatening position in the W-C Gulf, this run only moves it slowly back N to the end of the run:

    The GFS and Euro look like they’ve been trying to catch up with showing more vorticity and maybe a weak low developing, but time and shear may be inhibitors. There’s very clearly spin, but no convection whatsoever. It’s at least lemon worthy imo.

  8. Recon has been in Imelda and although it has not intensified much (there are stronger FL winds showing up now), it is confirming that the satellite appearance of more organization near the center is legit.

    Note that curved band of deep convection near the center, and how it is trying to wrap upshear. We'll see if the shear currently present keeps this organizational trend in check.

    My feeling is that it isn't going to snow anyway, and it's getting darker earlier, so I enjoy the nice weather being outside as much as possible.

    My energy bill appreciates it with no AC or Heat.

    By early to mid November, I'm game for sustained normal to below weather for snowmaking.  Have a full month+ though before it starts to matter.  48F and rain doesn't do much for me.

    I love fall and being in the Goldilocks zone for wx this time of year, so I’m with you on decent warmth—I just don’t like the upper level look. I want to see step downs. We keep saying these warm falls are fine and then I’m looking at +2 DJF and 30% of snow climo on March 15.

    I guess you could say I’m spooked :lol:

    That sounds about right as we head into the lower sun angle time of year.

    Mother Nature loves prolonging the sweet spot of temperatures in the 60-80F range as long as possible.

    I really don’t like this but if there’s a saving grace hopefully we snap back to troughing as we get closer to November.

    Put up or shut up time for the gulf

    Yeah Oct 7-20 is critical to my peak season forecast. I'm still thinking things heat up in the western Caribbean and Gulf during that period, and then we are winding down the season by the end of October. 

  12. Not much to say right now as Imelda continues to gradually (and slowly) organize. 

    KLd7Sy7.gif

    As the NHC notes, with the change in track forecast and further south position, this may end up in a more favorable position relative to the trough and SST/OHC, which could open the door for more intensification once this develops an inner core and pulls away from the coast. I think Imelda has an outside chance at becoming a major in the coming days. 

    SHIPS continues to show meaningful probabilities for RI.
