Highest wind gust here is 30 mph in the past ten minutes.  Wind gusts along the south shore of LI (Fire Island) currently gusting to 45 mph.

Severe Thunderstorm warnings out here for the expected winds with this squall line.  I am not presently detecting lightning with it.

Walt Reading is at 65 degrees.  Much higher than the 59 you wanted yesterday. Squall line approaching and should be here in the next 30 minutes.  

You will see some impressive winds with the squall line in a few minutes as a bow echo passes you.

Walt what kind of wind gusts were reported near ABE?

Wind gust to 63 mph reported at Altoona, PA with the passage of the squall line.  Wind gusts of between 20 - 30 mph are occurring ahead of this feature across eastern PA at this time.

you sure about Nov 24-30 1989?  I recall that being during the stretch of brutal cold that Nov into Dec

That was the year of our Thanksgiving snowstorm with 4.7” in Central Park on 11/23/89.

My max here has been 37 mph at 9:25 and 10:05.

Wind is howling out here in eastern PA with the passage of the cold front.  Wind gusts to 33 mph within the past 15 minutes.

GFS has consistently been showing a Caribbean hurricane that eventually goes up the east coast.

Strong WAR pattern would support such a track. 

06z GFS has it east of Cape Hatteras at 348 hours.  12z GFS has it west of Key West at 342 hours.  It’s an interesting thought anyways...

40.1 this morning. Radiated extremely well here

Same out here.  I am a native LIer and can tell you that there was an early season Arctic air mass that impacted the area back around 1974/1975.  This event produced high temperatures in the 40s and lows of about 30 on the north shore of LI during mid October at that time.  For the time of year it was impressive.  In any case  I have personally never seen frost anywhere this early in the season until today.

35 out here with patchy frost in the area.

Lots of clouds

 

 

Any one take notice of the shadowing effect on the cloud deck caused by the easterly flow drying out slightly as it crossed LI and NYC extending into eastern PA.  This has been seen on visible satellite almost all day.  This is not something that I can recall seeing.

This line is a fast mover but is not producing anything significant here except for a torrential downpour.  Minimal CTC and no significant wind as the 50 DBZ echoes pass directly over me.  0.65” in the rain gauge with this line so the mesoscale models did well with rain amounts with this feature today.

This line is putting out a lot of lightning right now as it comes out of the Poconos.  It is producing 2-4 strikes per second according to my Tempest.

Mt. Holly has issued a SSW for my area for the line heading towards me from Carbon County, PA.  Looks like it will be a quick hitter.

We are popped right now with an intense cell moving overhead and providing torrential rainfall.

Torrential rain is occurring with this feature.  It’s winding down here and we have picked up 0.79”.

An impressive light show with the squall line as it passes through.  Frequent CTC/CTG Is accompanying this feature.  No strong winds here.

NAM is looking increasingly lonely on the 18z runs in calling for higher rain amounts for tomorrow for the majority of the metro area.  The GFS and RDPS would bring heavier amounts to LI and parts of the city however most other model runs have negligible amounts except for central NJ and points south.

Decent batch of showers in eastern pa. Let's see if they hold

Heavy rain with thunder out here.  This batch means business.

Final rainfall total - 7.15"

My brother took this picture in Center Island a short time ago

Eerily calm right now.  Like 5 kts or less.

That passed through my area at about 1pm.

I am posting the 1PM Obs from Mount Holly. This is going to be representative of the weather of the next 2-3 hours in the NYC area. I am highlighted the calm winds at the observing stations in Bucks Cty near me where the center was at that time.
