    2 likely tornadoes otg NW of Savannah per radar. TOR threat ramping up with discrete supercells now developing 

     
     The dewpoints here are way up in the high 70s, something very rare this late into fall. That with the 86 temp gives a heat index way up at 99-100 on Oct 10th! It feels awful! The shift from E to SE winds allowed this:

     Wind gusts have picked back up with the increasing sunshine and winds at 5K feet being 30 knots (cumulus clouds are hauling) from the S along with strong SW winds at H5+ are setting up a potential for severe thunderstorms in this general area later this afternoon/eve.

  6. *I’ve received 0.75” so far from Isaias’ influence.*

      I just went outside and it felt like a midsummer steam bath! Then I saw that dewpoints are way up in the high 70s, something very rare this late into fall. That with the 86 temp gives a heat index way up at 99-100 on Oct 10th! The shift from E to SE winds allowed this:

     Wind gusts have picked back up with the increasing sunshine and winds at 5K feet being 30 knots (cumulus clouds are hauling) from the S along with strong SW winds at H5+ thus setting up a potential for severe thunderstorms later this afternoon/eve. The severe risk is only “slight”, but I don’t even recall that here anytime recently:

    Hurricane Isaias Landfall Accurately Forecast

    Timing Slightly too Slow

    The center of the rapidly degrading eye of Hurricane Isaias crossed the coast near Destin, FL with 105MPH maximum sustained winds at about 930PM EDT.

    FINAL%20CALL.png
     
    This was precisely as forecast in the Final Call issued this afternoon in terms of landfall locale and intensity, but the timing was about 1.5 hours faster than 11PM EDT forecast. Although the landfall intensity needed to be adjusted upwards slightly in the Final Call issued earlier today, the Destin, FL locale was consistent since First Call on Wednesday.

    Final Grade: A

     

    Fantastic forecast, Ray, that was spot on other than being slightly too slow!

    Regardless of strength (I’ve seen Andrew & Michael up close). Unless you have boots on the ground you don’t realize the amount of damage even a storm of this strength can cause. My thoughts are with the many people who are dealing with issues big or small. I can tell you the Emerald Coast got smacked by this. Glass half full thoughts, are the shear and dry air saved us from what could’ve been a monster!


    .

    I’m glad the expected last minute weakening verified well saving from a MH landfall, but realize getting cat 1-2 H effects is of course still a big impactful event (I know first hand).
     

     Interestingly per Dr. Knabb, that same strong shear that caused the dramatic weakening just before landfall actually caused the worst of the thunderstorms/wind gusts (solid cat 2 gusts) to be in your area in the NW eyewall (where Stephanie Abrams great coverage was). It’s almost as if the NW eyewall weakening lagged behind. She said she had never seen so much lightning in an eyewall, which typically has limited lightning due to the upper atmosphere being too warm for as much ice in the clouds vs typically much more lightning in outer bands as Dr. Knabb explained.

     I thought TWC coverage was excellent between her, Cantore showing storm surge and sudden shift to warming S winds off Gulf in E eyewall, and Dr. Knabb.

  9. Due to the pressure gradient between Isaias’ remnants and the wedge, along with sig. ongoing rain, together with a secondary astronomical tidal max due to the new moon, the NE winds were long and strong enough to produce moderate coastal flooding in CHS and minor S of there to Ft. Pulaski.

    0842 AM COASTAL FLOOD 1 E CHARLESTON 32.78N 79.93W 
    10/10/2026 CHARLESTON SC OTHER FEDERAL 

    A MAXIMUM TIDE LEVEL OF 7.76 FT MLLW (2.00 FT MHHW) WAS 
    OBSERVED AT THE CHARLESTON HARBOR TIDE GAGE. MODERATE 
    COASTAL FLOODING TYPICALLY BEGINS ALONG THE COASTS OF 
    CHARLESTON AND COLLETON COUNTIES WHEN TIDE LEVELS REACH 
    7.5 FT MLLW (1.74 FT MHHW) IN THE CHARLESTON HARBOR.

  10. In my area overnight, we got some beneficial rainfall from rapidly N moving scattered convection. Per Cocorahs, there was ~0.75” in the area. I’ll check my gauge later. Winds were brisk but no big deal as expected (highest gusts low 20s).

    Sun is peaking through. The sun will eventually lead to sig. instability, which will fuel scattered or bands of tstorms this afternoon, some of which could be severe with a couple of tornadoes possible.

  11. What was the actual lowest SLP at landfall ?


    -Lowest Destin SLP was at 8:20PM CDT per this link at ~982 mb (28.99” altimeter setting):

    IMG_2873.thumb.jpeg.2dad0411318b5156c743f9a51ac69360.jpeg

    -As this shows, winds were NNE at landfall time at Destin. That says landfall was just E of Destin.

    -Per Dr. Knabb per Cantore’s report of winds shifting to S off the Gulf at Miramar Beach before and during landfall time says landfall was just W of Miramar Beach.

    -There are 8 miles between those 2 locales. Thus, a good estimate is that landfall was 4 miles E of Destin.

    -How much lower than Destin’s 982 mb would SLP be 4 miles to the E? Anyone have a guess as to the gradient over those 4 miles W of the center?

    One thing I do like is stating "tropical storm conditions possible."  Yet the actual forecast is for 15 to 25 mph *sustained* winds.  That is well below the threshold.  Last I checked, tropical conditions are sustained 39 mph or more.  So there is hedging here is excessive IMHO.   Gusts to TS force are not the same as sustained TS force.  They are conflating things.  I see this a lot.

    And really, how often does TCL and esp. ATL, get sustained winds of 39 mph or more?  It is practically unheard of.  So climo comes into play here.  It would have to be an exceptional event for such winds, but Isaias as a hurricane and going ET are not by all forecasts.   This is not like Helene from 2 years ago.

    Just b/c something has a non-zero chance of occurring does not mean you explicitly mention it in a forecast.  Once again, hedging and inflating reasonable risk.  Wording matters as to how ppl will react, and then you get into the issue of things being cancelled and shutdown *way* too much for a run-of-the-mill event.

    Also, Isaias will no longer be a TC by the time ATL gets sig impact, and perhaps even TCL. so their wording is incorrect.  They should be saying "gale force winds", not tropical storm conditions. 

    This is a slippery slope.  Almost every winter storm on the E Coast has winds of TS strength, but you do not call them tropical storm winds!

    They should be headlining a wind advisory or high wind warning, not mentioning tropical in this case
    for TCL and ATL.
     

    Thanks.
    Whereas for TCL they’ve got a TS warning, they didn’t ever predict TS conditions for ATL. Instead they have a high wind warning:

    That's a good point.  TIMING is everything!  But I see far too often a wx event is taken as "all day" and so events that will clearly be before or after  sig storm impacts are done and do not be to be cancelled.  I mean, you now get *indoor* events cancelled for just some typical wind and rain now.  Really?

    We can fine-tune forecasts better than ever now w/ models like the HRRR, RRFS, and HAFS, so we do not have to just issue a generic, blanket forecast. esp for the short-range.  Having this capability saves an enormous amount of $$ and allows business and commerce to function better.

    It reminds me of something years ago.  One evening, I went out to get pizza, and when I picked up my order, the person said "it's been slow tonight b/c of snow forecast!"  You know what the forecast was?  1-3" of snow starting *after* midnight.  So my previous posits about business and commerce being impacts is valid, and it hurts revenue for many businesses, big and small.  You see how incessant hype and not quantifying risks/threats  properly are detrimental to society.

    Cancellation of a major sport event is non-trivial as to costs, and it goes far beyond just that single event.  They have to reschedule and that has downstream impacts often to the entire league.
    I often ask myself, what if the SB was in MSY or MIA, and there was a MDT or HIGH risk for svr wx for that day?  I would not want to be the one to make the decision!  In this case, the ante is extremely high on both sides!  Actually, I do recall a case like this.  In 2004, the Indy 500 was held despite a HIGH risk svr and a sig tor outbreak was likely.  And when the event was over and people were leaving the area, there were tornadoes occurring in the IND area not more than 5 mi away!
     

     
     The main issue some of us have is the double standard of concern in Tuscaloosa vs virtually no concern in ATL (at least earlier…maybe this will change). The forecasted conditions for during the GT/Duke game in ATL Sat. afternoon are far worse than those for even the tailgating period (6 hrs before kickoff) in Tuscaloosa. Furthermore, the forecast for ATL is actually quite a big deal, which along with thunderstorm chances has a high wind warning and thus would be far worse than the typical breeziness of a Miller A:

    i respectfully disagree with you. the 3 games i am aware of closest to the storm's impacts are Georgia/Alabama in Tuscaloosa (storm will be effectively over by kickoff), Georgia Tech/Duke in Atlanta (breezy and rainy, but no big deal in the whole scheme of things) and Vanderbilt/Ole Miss in Nashville (similar to Atlanta, with probably less overall impact, and less tornado threat).
     

     
     The point some of us have been making is the double standard being applied regarding the concern for the attendees in Tuscaloosa vs that for those in Atlanta:

     Tuscaloosa: SATURDAY  
    TROPICAL STORM CONDITIONS POSSIBLE. SHOWERS, COOLER  
    WITH HIGHS IN THE MID 70S. NORTHEAST WINDS 25 TO 30 MPH WITH  
    GUSTS UP TO 45 MPH, BECOMING SOUTH 10 TO 15 MPH WITH GUSTS UP TO  
    30 MPH IN THE AFTERNOON
    . CHANCE OF RAIN NEAR 100 PERCENT.


    Atlanta: SATURDAY  
    SHOWERS. A SLIGHT CHANCE OF THUNDERSTORMS IN THE  
    MORNING, THEN A CHANCE OF THUNDERSTORMS IN THE AFTERNOON. BREEZY  
    WITH HIGHS IN THE LOWER 70S. EAST WINDS 15 TO 25 MPH WITH GUSTS  
    UP TO 50 MPH
    . CHANCE OF RAIN NEAR 100 PERCENT.

    —————

     As one can see, the forecast is actually much worse for the afternoon gametime in ATL for Duke/GT than it is not just for the evening gametime in Tuscaloosa but even during the tailgating time in Tuscaloosa well before the game even starts!

     So, gusts to 50 with possible thunderstorms/heavy rain and even a slight chance for a tornado in ATL for the game itself vs gusts only to 30, much lighter rain, and no thunderstorms in Tuscaloosa during the entire PM tailgating period well before the game even starts!

    The hurricane was declared as such at 11:30pm eastern on 10/7 after a Hurricane Hunters pass. So it’s a little dicey.

     

    Of course there’s a good chance 1905 had a hurricane earlier in their season that we didn’t detect

    For those who didn’t realize it, 1905’s very late 1st on record H was similarly powerful to Isaias with it peaking as a MH (cat 3) and that was also during El Niño.

    *Edited: it was not the last storm of the season at genesis but was when it degenerated below TC status at its end.
