    0.01” In the last 3 hours here. I’m in the cutoff as you are. Upton’s QPF map is still bullish for our neck of the woods. We’ll see how it unfolds.

    The HRRR keeps trying to push rain west but its not happening on the radar.  The 18Z HRRR had rain pushed to our west at 4pm for example. 

  2. Mesoscale Precipitation Discussion 1112
    NWS Weather Prediction Center College Park MD
    1116 AM EDT Fri Sep 29 2023
    
    Areas affected...far eastern PA into NJ, southern NY/Long Island,
    CT and western MA
    
    Concerning...Heavy rainfall...Flash flooding likely
    
    Valid 291515Z - 292045Z
    
    SUMMARY...Flash flooding will remain likely across the tri-state
    region over the next few hours, some of which could be significant
    to major. Rainfall rates of 1-3 in/hr and additional totals of 3-6
    inches prior to 21Z should be expected, leading to a very
    dangerous situation if these totals overlap with 3-6 inches of
    rain which has already fallen over NYC.
    
    DISCUSSION...1445Z regional radar imagery continued to show
    widespread moderate to heavy rain across the NYC metro into
    southern NY/western CT/western MA. The highest rainfall rates were
    located just north of NYC into far western CT, along a low level
    convergence axis forced by a mesoscale circulation over NYC.
    Wunderground and NYC Mesonet/NYC Micronet gauge data has shown 3-6
    inches of rain has fallen across the Five Boroughs with rainfall
    rates peaking in the 2-3 in/hr range over Brooklyn around 12Z,
    resulting in numerous flash flood impacts across the region. While
    lightning observations have been largely absent, a few embedded
    thunderstorms have been observed where elevated instability of a
    few hundred J/kg was present, rooted near the 850 mb level via the
    12Z OKX sounding. Precipitable water values were near 1.6 inches,
    just above the 90th percentile for late September but despite the
    somewhat modest moisture, forcing for ascent was strong...owing to
    low level overrunning of an inverted surface trough which extended
    northward from the northern Mid-Atlantic coast into far western
    Long Island at 14Z. Low level winds centered near 850 mb were
    averaging 20-30 kt from the SE, supporting multiple rounds of
    heavy rain with recent redevelopment of heavier rain along and
    offshore of Manmouth and Ocean counties in eastern NJ.
    
    Pivoting of the 20-30 kt low level axis of winds to the north of
    an 850 mb circulation centered over southern NJ is expected to
    support the refocusing of heavy rain into portions of
    central/northern NJ while southeasterly flow maintains areas of
    heavy rain into southern NY and portions of western CT/MA, where
    terrain influences will augment rainfall intensities. The
    potential for 1-3 in/hr rates will remain with the higher end of
    that range more likely over far eastern PA into NJ where
    increasing instability into the early afternoon is expected with
    continued low level moisture advection, allowing for MUCAPE values
    in the vicinity of 500 J/kg. Flash flooding is likely to continue
    across the region, with areas of major flash flooding likely where
    overlap of additional heavy rain occurs with areas of ongoing
    flash flooding with an additional totals of 3-6 inches expected in
    some locations.

    i have seen many people wearing hoodies for the last few days now it is hoodie season!!

    If they told you that wolverines would make good house pets would you believe them?  Up to 64 under brilliant sunshine.

    If this rain keeps up and we continue to get below average temps, we’re in for amazing fall foliage, the likes of which hasn’t been seen in a long time. Get your cameras ready!

    All of the rain now will likely cause muted/washout colors this year, we'll see.  1.17" IMBY
