  1. If we did hit 100 here in CT, it’d be the first time in about 15-20 years we had a 100 in August. That’s impressive to me.
  2. Idk about NOAA @weatherwiz, but I love CSU and I think they look much deeper than general ENSO. To me they’re an example of people that do it right. There are always areas where I can personally improve with regard to tropical forecasting and understanding, but I think having a more granular understanding of the structure of ENSO/how it evolves, and a greater sense of how things like wave breaking and the MJO are forecasted would be valuable. But I work virtually every day. Honestly there are times I wish I could do a wholesale career change and go all in studying tropical meteorology, but I guess I’m where I’m supposed to be..
  3. Meanwhile, every rain shower turns into a named storm in the EPAC.
  4. That’s out of my depth. I’m just here for tropical lol.
  5. ACE has been shown to have a connection to winter, so it’d be appropriate here too.
  6. I could be wrong of course, but I just don’t see a 12/5/2 95 ACE season yet. If it were a Nino background, all in. If the MDR were -1.5-2C, all in. But we don’t have that. We have an absurdly stable late July/early Aug environment that can change, albeit slowly in the first 2/3 of August. Idk if I’d go well over average ACE to where CSU is, but probably solidly above given my MH forecast.
  7. Reposting what I originally wrote for the Mid-Atlantic thread. I didn't go into wave breaking like the tread above, but it's obviously pretty important. Also very interesting that SST anomaly plots are so different depending on what site you use. There's a long road between Aug 1 and the end of October, and in the Atlantic especially we can go from quiet to a massive uptick quickly. I don't think anything like 2013 is walking through the door absent seeing continued crap conditions around the end of August, when we're into the ascent to the climatological peak and can see deep into September on ensembles. End of July Tropical Update It's time to turn the page to August, and that means a deep dive into where we are and where we may be going as we approach the start of the climatological peak of the the 2022 Atlantic season. It has been nearly a month since the last named storm in the Atlantic (Colin) and it is immediately apparent why. While the EPAC is HOT, the Atlantic is about as dead as you can get. It has been a banner month in the EPAC, where virtually everything that tried to develop in the basin has developed. The EPAC has seen 5 named storms in the month of July, and 4 have become hurricanes with 2 of those majors. That puts the basin about a month ahead of both hurricane and major climo overall. The background environment has allowed for rising motion that strongly favored convection in the Pacific. Think MJO. It has been steadfast in supporting EPAC activity. The rule of thumb is when one basin is hot, the other is quiet in our part of the world, and that has certainly been the case in the Atlantic where sinking motion, lack of stalled fronts off the SE and Gulf, and monsoon trough along the African coast allowing for SAL in the MDR have suppressed not just activity, but convection itself--the seeds of a TC. It's hard to state just how bad this pattern is for the Atlantic currently. Even though this tends to be the downward peak of dry air in the Atlantic, it is extraordinarily dry. You can see it in the satellite image above, but you really see it with the SAL Analysis. It's nearly impossible to get anything anywhere outside of the Gulf with this environment. The MDR, Caribbean, and even western Atlantic/SE coast are dry. To be clear, it's more complicated than just dry air. Combined with other factors like stability in the region, it's a toxic combo for any wave trying to form. To make matters worse, there is a nasty ribbon of shear that would rip anything apart in the Caribbean (normal this time of year) and anything that tried to develop and move westward in the eastern MDR. It's easy to look at these plots and feel the urge to cancel the rest of the season. How could the Atlantic recover with that kind of dry air and stability in the MDR? How could we see long track hurricanes with shear this high? I strongly urge caution in cutting back forecasts for an above average season. 1. Generally Speaking, a Quiet Atlantic This Time of Year is Climo There's no way to sugarcoat it: the current Atlantic pattern is truly awful for TC genesis. That said, this time of year the pattern usually leaves a lot to be desired. In recent years, very active years by the way, we saw fairly dramatic pauses in Atlantic activity during this time. Although the season starts on June 1, by the time we get to August 1, we still have approximately 90% of tropical activity that is yet to occur. July tropical activity is almost exclusively confined to the homebrew regions of the SE coast, Gulf, and Western Caribbean for a reason--the broader basin is not ready for major activity via African waves in the Atlantic and Caribbean portions of the MDR. That means it's folly to make a prediction on what August and September will look like with regard to ACE and absolute TC numbers based on July activity. Image courtesy of Michael Lowry. 2. Signs are That the Basin Will Gradually Become More Favorable Now, this one is easy. We're headed toward the peak of the season, which broadly runs from August 20-October 20. Usually the switch flips and we go from quiet to very active. The PAC will not continue on this heater, and while we had a false start signal from the models about two weeks ago that highlighted the end of July/early August as the period the switch would flip, it's important to look at the puzzle pieces they try to throw out. First, it's looking like rising motion will become more favorable by mid-month in the Atlantic and favor more vigorous waves off Africa, right in time for the start of CV season in the Eastern Atlantic (image courtesy of Andy Hazelton). This is critical, because we will need moisture to get injected into the basin. second, it looks like shear will begin to decline. This is consistent with -ENSO climo, so it wouldn't be a surprise that things begin to change as we get closer to the peak. Things are rough according to an EPS mean at the start of August, but as we get closer to the peak, the signal is for a less hostile basin. 3. Despite Mixed Environmental Factors, ENSO and SST/OHC Still Rule the Day Finally, ENSO still matters. We are going to see a La Nina/-ENSO state during the peak of the season. This is clear and unambiguous. Normally, -ENSO produces a broadly favorable environment. I will note that @GaWxhas done some excellent work that challenges the premise that a third-year Nina must necessarily be active, but I do think that an active WAM, reduced shear typical of a Nina, and importantly, near normal MDR/cool subtropics and warm western Atlantic will allow for an above average (but not hyperactive) season. Overall I started the season with a 21 named storm/10 hurricane/5 major hurricane forecast, and I don't see much reason to change that right now. I do think we get some activity before the climb toward peak begins on August 20. Overall, I think stability in the MDR will take the longest to overcome, but the other factors I listed above should be able to overcome that. As I've said the last few years as well, I think a relative lack of activity in the Eastern Atlantic can be countered by increased activity in the western Atlantic, where SSTs and OHC are higher than usual. I should note that my usual TCHP charts are inaccessible, but based on what I saw earlier in the month, the depth of ocean warmth is on par with our other recent active seasons, especially in the western Atlantic.

  9. Just looking at ACE, originally I would have been inclined to say that the -ENSO alone puts us in a place where average ACE is a floor, but that'd be lazy analysis. In fact, @GaWxrecently posted some great stats that show there tends to be a dramatic drop off in activity in a third-year Nina, though the sample size is on the smaller side. That gives a little pause, but I didn't expect hyperactive to begin with. That said, while I think it's tempting to look at a slightly cooler than normal MDR and the incredibly quiet Atlantic as a harbinger of things to come, I don't think it's going to get in the way of a very active peak that should bring us to at least average. I know you know this, but we still have approximately 90% of climo to go with regard to Atlantic activity, and there have been numerous examples this century of long quiet periods and less than favorable eastern MDR conditions that fail to get in the way of a season with a favorable background state becoming above active. I still think the combination of a Nina, lower than normal shear driven by the Nina, and importantly, warmer than normal temperatures and TCHP/OHC throughout the western Atlantic suggest a season that gets the Atlantic above 123 ACE. Not worried about the SAL--that'll diminish near the peak. I do think stability in the eastern MDR could be a fly in the ointment, but I'd want to see what that looks like in mid-August.
  10. The seller left behind brand new rakes, shovels, and hedge clippers. I guess they thought they’d use em and never did.
  11. Yeah—it’s entangled with at least two trees. I’ll be busy keeping it in check. I just looked that up. I don’t think it is? And yeah, there are levels to the overgrowth thing. At least nothing is growing on the house lol. The neighbors said they only mowed three times in the last year. Today I discovered while pulling weeds in the front that some of the driveway was just covered by weed/grass. Stuff literally grew on top of the asphalt and made it look like it was a grassy barrier with the neighbor. I’m new to all of this stuff so I find all of it interesting. I’m the first in my family to own a home. The yard is a blank slate.
  12. Yeah—very quiet. Thought we’d be heating up around now but that’s obviously wrong.
  13. Not quite yet. Closed on a house two weeks ago here in town and am trying to get some work done before moving everything in. Fortunately, nothing major.
  14. Prior owners left a mess so I have to get things under control. Will be nice to not have to mow a lot though.
  15. GREAT day to get some yard work done.
  16. This is the first time I’ve ever really had a yard, and while it’s a lot of work I love it. I probably won’t be go crazy with it just because I can’t justify spending a lot of money on this to the wife, but I’ll make improvements where I can. The prior owners left a ton of overgrowth and weeds in the front and back. I’m two weeks in and it already looks much better after a mow. The overgrowth on the sides are so bad.
  17. Ol’ Euro ain’t what it used to be.
  18. I don’t like the naming, but categories for heat waves would be helpful. They’re not all equally impactful.
  19. So glad I posted here. It helped me remember. Just made a small donation @Typhoon Tip. Thank you for sharing.
