  1. Question: does a warmer fall usually increase the chances of a strong lake effect season?
  2. Looks like additional data tonight with the supplemental soundings, and G-IV stuff by tomorrow night. I think tonight will be important in narrowing down the envelope of solutions, but the trend is clear.
  3. Hurricane Maria Discussion Number 30 NWS National Hurricane Center Miami FL AL152017 1100 AM EDT Sat Sep 23 2017 Data from this morning's Air Force Hurricane Hunter flight suggests that Maria's maximum winds may be decreasing a bit--a trend which was noted in the previous advisory package. The plane measured a maximum 700-mb flight level wind of 102 kt and SFMR winds as high as 85 kt, neither of which supports an intensity of 105 kt. The initial intensity is therefore conservatively lowered to 100 kt. Maria is now located between a mid-level high centered near Bermuda and a cut-off low over the northeastern Gulf of Mexico, both of which are steering the hurricane north-northwestward, or 340/7 kt. Maria should turn northward between these two features beginning in about 12 hours, but its forward motion is likely to be impeded in a couple of days by ridging developing over the northeastern United States. As a result, the hurricane's forward speed will decrease to 5 kt or less from day 2 and beyond. The track guidance has continued to trend toward slower and farther westward solutions, and as we had foreshadowed in previous discussions, an additional westward adjustment to the new NHC track forecast was required on this cycle. The updated forecast is between the GFS and ECMWF solutions and close to the consensus aids and HCCA through day 3. After that time, the new forecast is slower and southwest of the consensus aids, but still not quite as far west as the GFS, ECMWF, and UKMET solutions. Based on various analyses, the southwesterly shear over Maria has decreased since yesterday, and it appears to remain relatively low for the next 2 days or so. Maria will be moving over very warm waters during that time, although the depth of the warm pool does decrease, and Maria's slower motion could increase the effects of colder upwelled water. After 48 hours, vertical shear is forecast to increase again, and a critical part of the intensity forecast will be whether or not Maria moves over the cold wake left behind by Jose. The recent westward shifts in the forecast track make it more likely that Maria would avoid the cold wake and move over the warmer Gulf Stream waters. Since the environment may not be as hostile as the dynamical models are assuming, the NHC intensity forecast is a little above the intensity consensus for much of the forecast period. To increase the sampling of the environment upstream and north of Maria, supplemental 0600/1800 UTC upper-air soundings are scheduled to begin from the eastern and southeastern United States this afternoon. In addition, NOAA G-IV missions are scheduled to begin sampling the environment around Maria on Sunday. KEY MESSAGES: 1. Maria's forecast track has shifted closer to the U.S. east coast, and it is becoming increasingly likely that some direct impacts will occur along portions of the coast next week. Interests along the coast of the Carolinas and the Mid-Atlantic should monitor the progress of Maria, as tropical storm or hurricane watches may be needed for part of this area on Sunday. 2. Swells from Maria are increasing along the coast of the southeastern United States and are expected to reach the Mid-Atlantic coast tonight and on Sunday. These swells will likely cause dangerous surf and rip currents at the beach through much of next week. For more information, please monitor information from your local National Weather Service office at www.weather.gov.

  4. Further west and like a day faster than the op.
  5. To do a somewhat serious analysis... If you notice the time stamp, the Ukie's SLP position actually looks really close to the Canadian run tonight at 96. The GFS is much slower--well SE of the NC coast at the same time. I think the speed allows for Maria to get further north, but unlike the Canadian, where the kicker takes forever, the Ukie has it come in pretty quickly, which gets Maria to take that sharp turn east before getting as far north as the Canadian. We'll see what the GEFS, Euro, and EPS do. Like I said a few days ago, this doesn't look like an "inland" landfall type pattern, but a landfall along the far east NC coast can't really be ruled out. Up here, it looked like we were out of the game (at the shore) but maybe Maria is trying to walk through the door. Have to be careful about going all in because models can easily overcorrect in both directions. Really interesting seeing the trend being a closer approach though. That's hard to ignore as we get closer in time.
  6. Ukie ain't pulling any punches tonight!
  7. Doing my level headed best to not get sucked in. Just watching casually. Faster forward motion and a slower kicker would make for a very nice beach day.
  8. GEFS look robust. Worst day of the week for me though lol
  9. Winter makes us crazy. Most of us love winter more than tropical, and love makes us blind
  10. Slow moving and decaying hurricane moving north? Perfect for the non-damage inclined weenie. It'd be a shame to waste that opportunity
  11. Thanks. I still don't think Maria's walking through that door, but if it gets close enough for a legit scrape that'd be a little fun.
  12. Another tick west on the Ukie? Hard to tell with those God awful maps.
  13. I'm still out, but I'm liking the west trend.
