  1. From KGSP.  Will be a mess for early travelers, but we need the rain!  This should kick off an active couple of weeks.

     

     This high will remain
    transitory into Mon and ridge down the east into the FA maintaining
    near normal temperatures. Meanwhile, northern stream Pac energy
    combines with the srn STJ over the West in a split flow regime,
    which then creates a well defined and deep mlvl trof across the MS
    Valley by Mon night. This trof will be highly dynamic as deep
    layered shear nears 100 kts and combines with good GOM moisture flux
    and creates a good set-up for sigfnt rainfall and possibly a few
    organized thunderstorms across the srn half of the area. There`s
    remains uncertainty with the amt of destabilization ahead of the
    llvl forcing, but the model trends are going up with the ECMWF and
    CMC models indicating arnd 200 J/kg of sbCAPE within the warm sector
    during max heating. So a high shear / low CAPE strong storm
    environment is looking more possible. Soundings also show very high
    levels of 0-3 km helicity (>600 m2/s2), however, this is mostly due
    to the aforementioned sfc wedge producing ne/ly at the sfc. But as
    usual, the wedge bndry areas will suspect for more organized cell
    development. In any case, this system looks to be a good precip
    producer, the best in the last few months, with possibly 1.5 to 2.0
    inches of rain over many areas thru Tue night. With high cloud cover
    and ne/ly flow, highs Mon thru Wed will be held abt 5 degrees below
    normal with lows averaging arnd normal.

  2. Looks like we could get a coastal low on Sunday.  Not a moment too soon.

    .LONG TERM /SATURDAY NIGHT THROUGH MONDAY/...
    As of 110 PM EDT Tuesday: Rainfall will continue on Saturday as the
    surface front makes its way across the region...likely exiting to
    the southeast by late Friday night or early Saturday morning.
    Thereafter, deterministic guidance continues to depict it stalling,
    whereupon a robust upper shortwave will arrive and instigate
    cyclogenesis along the Carolina coast.  This`ll give us another shot
    at some rainfall...with the new QPF forecast giving the SC zones
    another 0.25" or more on Sunday and Sunday night (more than half an
    inch per the 12z GFS, which ironically has trended toward stronger
    cyclogenesis than the ECMWF after barely developing the feature at
    all on the 06z cycle).  All things considered, while this rain won`t
    quiet offset the ongoing drought, it`ll bring some much-needed
    moisture to the region.

    Gulf Cold

    I was a senior in college in 87/88 and October was really cold in the upstate.  I think GW posted a correlation between BN October’s in EN and wintery precip.

    I remember many days going to lunch with temps in the low to mid 50s.  We had snow flurries on Halloween and big snow in January.  
     

    86/87 was a EN year too but don’t remember October being cold.  Of course JFM were really good that year.

     Yep, obvious huge difference between controlled fire and a wild fire!

      Meanwhile, per model consensus, parts of the SE US are quite possibly going to be threatened (W FL)/affected by a new TC forecasted to start forming in the NW Caribbean or SE GOM this weekend and then moving NE across FL and/or further up into the SE Tue-Wed. Folks should keep an eye on this just in case although I have to go all of the way back to storm #6 of 1880 to find an analog of this in late Aug or early Sep during El Niño:

    Of course it’s a historic anomaly.  I’ll be at Myrtle Beach Saturday - Wednesday.

  5. While we deal with this ongoing hot pattern...latest ENSO predictions increase chance for moderate to strong El Nino.  97/98 and 15/16 are analogs.  Neither were stellar years in the SE FWIW but it only takes one!

    The most recent IRI plume indicates El Niño will persist through the Northern Hemisphere winter 2023-24 [Fig. 6]. Forecasters favor continued growth of El Niño through the fall, peaking this winter with moderate-to-strong intensity (81% chance of November-January Niño-3.4 ≥ 1.0°C). An event that becomes "historically strong" (seasonally averaged Niño-3.4 ≥ 2.0°C), rivaling the winters of 1997-98 or 2015-16, has an approximately 1 in 5 chance. In summary, there is a greater than 90% chance that El Niño will continue through the Northern Hemisphere winter [Fig. 7].

    Dang looks like Asheville East is absolutely taking a beating this evening. Looks like a storm is just training there. 

    Yeah, we were under it.  About 3.5 hours moderate to heavy rain.  Lost power for 2.5 hours.  Not complaining.  We were very dry.

  7. Looking ahead to fall and winter.  Odds are increasing of a moderate to strong El Nino in the late fall and winter.  Climatologically, not great for SE snow but has to be better than 3 years of Nina.  I have posted the strong to moderate El Nino years below.  There are some winners in the there for major storms...
