SACRUS

Smoothed out but rain chances Wed evening, Thu evening and each of Fri - Sun could get some localized spots >2 inches plus where storms fire. The weekend looks mainly ok hot/humid but scattered storms so far.

Dew point holding steady at 74-75 here. Fungus/mildew/mold spores must be high still. Hope the sun can temper those.

Again the issue more with central park is its used for the center / mecca of NYC weather when reporting. So for example today's the first 90 degree day in NYC when in fact there have been between 2 - 4 already. First 100 degree day in 13 years when there have been more recently in NYC/NJ metro proper. Perception.

Make me affirm that had we not been cloudy highs would have overperformed yesterday and will have the same potential today as we are seeing - minus seabreeze affected sites.

91 / 74 here. In line with past upper 90s/low 100s

Hotter in NYC/EWR than Vegas these next 2-3 days

in 2021 it did get into the upper 90s a few stretches in both July and August. EWR came just shy with 99 , 98's

Thurs is one of the days that will either be well below or way higher than projected for highs pending on the storms. Friday looks much a lock for onshore / cooler and cloudy day. Sat/Sun Flordiay style with sun hot quickly, weatch for storms.

89 here already and launching clear so far.

Had posted last night that this ridge position and >594 DM is similar to Jul 18-19 2013 where all sites except the park got to 100. I think its closer to that , than last year's.

Both GFS/Euro maintain a warm and storm free 4th Mid 80s - low 90s area wide. Similar progressions - GFS a hair warmer. 276 hours out now. 2-3 : warm / humid mid 80s - low 90s 4th: warm / humid mid 80s - low 90s 5-6 : a bit wetter / storms possible

Part of a severe weather outbreak that produced over two dozen tornadoes from Illinois to West Virginia, up to 10 inches of rain fell in just 12-24 hours on June 23, setting off West Virginia's third deadliest flood.

I am let it be hot in the summer and let it snow Thanksgiving to St Pattys day kinda of old timer. I do appreciate a dry heat / So Cal Palm Springs style .

87 / 75 hot / humid and mainly clear. 72 hour (6/23 - 6/25) the heat - near or record heat this is, is on. Mid - upper 90s with some of the hottest spots getting to 100 today. Widerspread 100s minus any of the caveats of clouds and seabreeze. Could be 3 lows >80 in the metros. Wed its a race to see if storms/clouds arrive before the hottest spots get to the century mark. Clouds/showers could muddy up continuing the heatwave on Thu (6/26) before more prominent storms come through later thu into fri/ Friday clouds, showers and onshore keeps it in the 80s/ 70s. The weekend looking to conitnue the trend with the threat of showers as the boundary linger near by, otherwise warm-hot / humid. Next week and leading up to the 4th - overall warm / humid and wetter. Ridge and heat building north and east towards the 7th. 6/23 - 6/25 : Strong Heat - upper 90s, 100s - lows >80 6/26: Hot/humid storms 6/27: Break in heat for all - clouds/showers 6/28 - 7/1: Warm-hot, humid - storms could keep it wet but period of sun (90s possible 1-2) 7/2 - beyond : Warm / humid - storms chances . Hotter towards the 6h/7th

10PM EWR: 87 LGA: 87 NYC: 85 JFK: 85 New Brnswck: 82

Similar ridge position and forecasted 850 MB temps (100s) Park of course missed , especially having come out of a very wet June 2013 7/18: EWR: 101 LGA: 100 JFK: 100 NYC: 98 7/19: EWR: 100 LGA: 100 NYC: 96 JFK: 95

On a side note the ECMWF AI Ensembles package will launch July https://events.ecmwf.int/event/487/ On Tuesday 1 July 2025, the first version of the Artificial Intelligence Forecasting System (AIFS) Ensemble model will be released and supported operationally. This release marks another milestone in ECMWF history, as AIFS ENS v1 will be the first AIFS ensemble model to be made fully operational. AIFS ENS, v1 model will not be an upgrade of currently experimental diffusion AIFS ENS model. It is a first version of a new model that is trained using a version of the Continuous Ranked Probability Score (CRPS), a loss function that helps ensure the forecasts are both accurate and well-calibrated. In addition to operationalisation of AIFS ENS, v1 will bring several new data and graphical probabilistic prodcuts available in the EMCWF Open charts platform.

Looks like 105 in NYC / NE-NJ NYC/NJ metro

9PM LGA: 88 EWR: 88 NYC: 85 JFK: 84 New Brnswck: 83

Still 85 / 73 here nice lifting board for tomorrow.

Similar placed ridge at 500MB to Jul 17-18 2013 which produced 100 degree heat.

Both the GFS and Euro maintain a warm-hot and steamy day on the 4th low 90s metro, upper 80s coast beaches with no rain. 2-3 : warm / humid 5-6 : warm humid storms on the euro on the 6th

What is left of the MCS and clouds still seen of the last few loops riding around the rim of the expanding ridge

Clouds through 4PM and still made it to 90 here, in most placed even with almost a full day of clouds forecasts highs were only missed by 6 - 8 degrees. Had we partly cloudy/ sunny conditions - highs would have over performed in my opinion.

Clouds spoiled a clean sweep but late in the day comeback almost got all stations there. EWR: 92ISP: 91JFK: 91TEB: 91LGA: 90ACY: 90New Brnswck: 88BLM: 88NYC: 88PHL: 88TTN: 87
