Syosset area getting pounded. There should probably be a flood advisory there. Edit-just saw it lol. 

Yes, my house is getting slammed at the moment.  Almost 1.50" of rain in little time, currently 1.43" and going up.  Gusted to 43mph as well.  Meanwhile my mom in Muttontown, 3 miles W, only .08 so far.

Up to 1.72" now at 2:35pm!  Wife says Split Rock Road is a river with lots of flooding.

That’s pretty much to be expected from the NAM since it hasn’t been upgraded since March 2017. Over 3.00” now on Eastern LI. This is where the signal for the heaviest rains have been from most models since its closest to the subtropical low.
 

NAM development was frozen after the March 2017 upgrade, and RAP/HRRR development with the WRF-ARW model will cease after the RAPv5/HRRRv4 upgrade in 2020. However, operational execution of these modeling and associated DA systems will continue until comparable FV3-based systems are able to give similar performance.

 

Is there a timeframe for retirement of the NAM?  I thought it was suppose to be this year originally but haven’t seen anything since.  I recall there was some slide from a NOAA presentation on model implementation & upgrades that showed it a few years ago.

1.01” in Syosset from last night & this morning. 

.67 in N Syosset, I’m sure LIE/135 area got close to 1”. 

Flood advisory issued. .40” so far and still coming down.

65/63, still rather dewy out here

All obs sites are 55-60 for DP.  Your sensor needs time to dry out or it has dirt around it.

63 in Muttontown & 65 in Syosset this morning. 

1.64” in Syosset & .97” in Muttontown. 

Flood warnings out now as well for part of metro.

  Kings (Brooklyn) County in southeastern New York...

  New York (Manhattan) County in southeastern New York...

Wish I could post the 40 second video from my sis in-law’s house on the water in Bayville. Nonstop lightning and some strong gusts when the sky is lighting up. Line just hitting Syosset now.

Guess that cell that passed over Syosset caused issues for LIRR:

Train service on the Port Jefferson Branch is suspended in both directions between Hicksville and Huntington due to signal trouble near Syosset. Use alternate branches where possible, including the Ronkonkoma Branch. Maintainers are en route.

.32 in Syosset as the cell moved through. .00 3 miles away in Muttontown.

For every NYC station there are 5 rooftop/tarmac stations that are just as useful

Manhattan microsites back up Central Park temp since winds were out of S mostly yesterday. Need that due W wind for the heat.

The very wet vegetation at the park limited the high to only 94° yesterday. So we may not see another 100° in Central Park unless a place like Newark makes it to 105°. Since on the very hot days NYC runs about 5° cooler.

Looks like it will make it to 12 years 

 

 

very few areas hit 100 down there 

Looks like the hotter temps were just S of PHL.  I see DC and Baltimore are 103 & some parts of NJ hit 100 as well.
