  1. Great sat. image depicting the strong SE ridging in place. The cumulus streaks over IL/IN almost look like isobar line lol.
  2. Didn't even get a 10th here. Soybean fields around here are crazy. Crops that are in the lowest parts of the field are full green and growing, The others are so brown and dry they're ready for harvest, not to mention they're less than a foot tall. You can see it field after field. During a wetter period the ones that are doing good would be stunted and visa versa. Corn crop is very noticeably short and stunted. My yard was wet at 5:30 this morning when I got home it was bone dry again. Tree's taking it hard too, the early turners are going straight to brown.
  3. This is getting ridiculous. The N part of this front is falling apart as it comes through this area. This is like the 3rd one over the last 3 weeks where the precip went N and S of here.
  4. Hoping we get something tonight. It's parched around here. Any exposed bare ground looks like a dried lake bed. No measurable precip locally for almost the entire month.
  5. Katrina hit the east coast of Fl. also. Currently the environment is pretty hostile in the far eastern Carib (as usual), but as you move west it gets much more favorable. Karen has some really good divergence overhead currently, much more than Jerry ever had. The Euro has been doing some tricky things with Karen the last day or 2 as was posted in the hurricane season thread. There is strong model consensus of ridging to the north building in in 3-5 days, strong enough to perhaps even push Karen back to the SW. We will see where she's at and what her attitude is when and if that truly happens. We are a week away from Oct. and if I still lived on the West coast of Fl. I would really be keeping my on this one. Fantasy land guidance is showing a nice path into west Fl. if something can slip into the SW/S GOM.
  6. You can really see the mid level vortex take off here..... https://weather.cod.edu/satrad/?parms=subregional-E_Antilles-09-48-1-100-1&checked=map&colorbar=undefined
  7. Lets see how the track responds. That UL ridging has been tight and strong just to his E/SE. It's expanded over the last 24 hours. It's not uncommon for weaker storms to slip under these like a mouse dashing for cover.
  8. Sorry was tongue in cheek post, Jerry, my avatar, back from the dead lol.
  9. My micro climate around here haven't recorded but a few drops of precip, less than .05 except for dew in the mornings, in almost 3 weeks.
  10. So we have Dorian coming close then OTS, OTS progressively east as the western side of the Atl. ridging gets beaten down. That rubberband has got to snap and something's going to get caught under a robust westward building ridge at some point I would think.
  11. Yes Kermit will be able to get to Jerry and the next system from Barbados and/or St. Thomas. logistical management on tight budgets lol.
  12. NOAA will list re-locations as training missions sometimes. haven't had a chance to look but kermit could be heading to one of the leewards to prep scouting the next system which has a much better chance of being a threat.
  13. All of the sat info and model info we get is basically in 2 dimensions through levels to interpret. Especially with the models we know they are resolving in 3 dimensions but the info presented at least to us, is in 2 dimensions via layers. There maybe something out there that can help us armchair guys visualize the model output in 3 dimensions but I haven't seen it. Kinda like GRlevelx? Storm specific I like the AMSU cross sections but something like that that you could "fly" through the model output. Hey look at my avatar, it's TS Jerry, I'm gonna reach
  14. A lot of Jerry's future stems from interaction with a mid latitude trof which as was said in the 5pm discussion can be very hard to forecast this far out. While Jerry's not going to be in perfect conditions beyond 24 hours, as has been alluded to, this has a chance to be another sneaker. Looking at the current CIMMS layer maps that's just some weird stuff going on for this time of year IMO.... http://tropic.ssec.wisc.edu/real-time/dlmmain.php?&basin=atlantic&sat=wg8&prod=dlm4&zoom=&time=

  16. From the Meteosat it's looking like the wave train is full steam ahead. There are several strong and a couple weaker ones lined up like a bowling ball return. We'll see how it pans out, but with the activity over equatorial Africa and the incoming Kelvin Wave it could get very very interesting. Seems #10 and the next wave models have are going to have some decent SAL to fight off so we shall watch the battle begin.
  17. I've actually seen some Maples starting to lighten up around here. The conifers on my property are producing large cones a good 2-3 weeks ahead of time. With the cool temps lately and the looks of the tree's would've thought we were into late Sept. not early. As is usual with a departing strong tropical system ridging building in behind it tends to pump our temps. But looks to be fairly short lived with the models pointing to another cool down beyond 5-7 days. I really hope we can experience a "true" fall this year. The falls I remember 40 years ago with comfortable to sometimes warm daytime temps and cool jacket wearing nighttime temps, heralding in high school football season, just haven't materialized in my 7 years back. It's my favorite time of year. Hope we actually have one this year.
  18. Strange but intersting mode around here today. Been on the road most of the day. I've experienced elevated thunderstorms, strong ones, but not as cellular as these. There was one from my location I literally could watch it work it's way down to the surface. I've never visibly seen that, was pretty cool.
  19. I've never been able to tweet embed. True story
  20. Spent about 15 years in Fl. Experienced some good ones. Some I chased some didn't have to. Elena (72 hours of hell), Andrew (West coast still a monster), Katrina (scariest cat 1/2 ever), Ivan (was prepared and actually enjoyed it) to name a few. I'm of the opinion know where you live. Canes come with the territory down there so deal with it and prepare yourself. For most of Fl. it's not that hard to evacuate 20 or 30 miles inland (if you have to go that far) if you live within 5 miles of the coast and then hunker down. If you live in Fl. and your evac plan is Georgia move back up north lol. Pinellas county (St. Pete, Clearwater, Largo area where I lived) is just a disaster waiting to happen however because there's just nowhere to go. Water on 3 sides, an average above sea level of about 15-20 feet, 4 bridges and a highway paralleling the coast north the only way out for about 1 million people to evacuate. It's been like 100 years since that area was slammed with a big dog and it will happen again. IMO that area is a powder keg during cane season.
  21. Need to freeze frame the weather forecast for this week. Freakin awesome
  22. Yeah MI has been drowned out by the MN WI stuff bu they've been getting hammered. Had some long trainers over night.
