Wettest September on record for ISP. This was the 3rd consecutive month with part of the area recording 10”+ of rain. So plenty of clouds and onshore flow kept the minimum temperatures up and the maximums down. 10 Wettest Time Series Summary for ISLIP-LI MACARTHUR AP, NY - Month of Sep Click column heading to sort ascending, click again to sort descending. 1 2026 8.76 2 2 1966 7.50 0 3 2008 7.46 0 4 2023 6.78 0 5 1975 6.57 0 6 1996 6.41 0 7 2004 6.37 0 8 1974 5.95 0 9 1999 5.65 0 10 1978 5.56 0 Monthly Data for September 2026 for Upton NY NWS CWA Click column heading to sort ascending, click again to sort descending.

At 2.10" MTD we will finish yet another month well below normal in the rainfall department. In fact, we have finished BN in precip in 12 of the last 13 months at my location (comparing to RDU average monthly totals). Falls Lake which made a huge recovery after the record wet July has tanked and is now more than 5 feet below full pool. Kerr Lake has continued its fall and not sits more than 11 feet below full pool. The fall is typically when reservoirs are at their lowest but these levels are well below expected normals and will set us up poorly for next year unless the pattern changes for the region. I know El Nino SHOULD produce AN precip during the fall and winter across the area, we are at the point now where we need it to produce. Fingers crossed this weekend is the start of the change

Well... it's done (not a subtropical storm but...big moderate, spotty major impacts with 2-8" of Rain I95 corridor, two surges of power outages, at least moderate CF and at least moderate dune damage). I sure hope everyone agrees it was VERY well modeled by the EPS/EC suite vs the United States GEFS back at least to 9/21..., a very good planner. Debris cleanup now. Will check back when we get some comparable headline extensive moderate or major impact coastal storms this winter.

Yeah we should. Plenty of rain/no drought and temps haven't been too hot. Looks like a really great stretch after this week too. As long as it's not stormy we should have a great season

I’ll take it after this disaster.

Driving up 287 into NY today from NJ I noticed some color starting to show up on many trees. I wonder if we will get some nice colors this year. Last year was blah imo, 2 years ago was awesome.

Temperatures can stay the same though. Dry and 70 please.

I could see a sneaky 90 around on Thursday or Friday

leaving methuen with rain or a few flurries...

Foggy morning here, maybe ~200m visibility off my balcony. it's been lingering for about 2 hours now, kinda surprising given the sun's been up

Fire up the muggy meters!

I have not had the AC in 3 weeks... Almost had to turn on the heat on this weekend.

Was this a bad storm? Absolutely. But we’ve seen plenty of those since especially around 2010. March 2010 for example was devastating for many because of tree/power damage and we’ve had many more since. For coastal flooding in the back bays I think it briefly hit Major status which is what was expected. Upton was a little slow to catch on but eventually upgraded the coastal areas to high wind warnings and flooding was about what was expected. For days models had the 4-5” rains a chunk of us experienced and Upton had a similar total precip map out. The wet grounds aided in uprooting trees vs if we had dry conditions this summer. The beaches got pounded due to the storm lingering for days and yes it’s rare we get these so soon in September. But compared to other storms we’ve gotten in the last 15 years or so is it that historic-no. Disruptive yes.

Yeah I thought today was supposed to be mostly sunny and in the mid 70s.

Some dews as well.

Yeah... we are a 13U and still have 8 core players from when we started at 9U.

Torch relative to the time of year on Thursday/Friday. 80-84 in this area.

Ok storm passed 2 days ago, the clouds can go now.

Short-lived.

If it was winter, it would’ve cut 300mi west or have gone out to sea.

Happy Red October (a little early) for those that celebrate - GO PHILLIES! A nice stretch of warmer weather and sun through the remainder of the work week with temperatures possibly touching 80 degrees by Friday! We turn cooler again and wetter by the weekend.
