Made it up to 95 at my station. 

[Rmine1]

91 in Brightwaters, which is quite impressive given our proximity to the Atlantic. Hottest day here so far 

note to self: don’t walk 9 miles in this heat. too late 
 

 

[weathermedic]

93 at JFK and 95 in Atlantic City. Westerly wind doing it's thing. Dews around 60 so not opressive.

Maybe some compressional heating near the barrier islands. Seeing a 96 and 97 in the Five Towns.

   Areas affected...portions of the Mid-Atlantic into southern New
   England

   Concerning...Severe potential...Severe Thunderstorm Watch likely 

   Valid 201752Z - 201845Z

   Probability of Watch Issuance...80 percent

   SUMMARY...Widely scattered thunderstorms will bring a risk for
   damaging wind gusts and isolated large hail through this evening. A
   Severe Thunderstorm Watch will be needed soon.

   DISCUSSION...Latest surface observations indicate that surface
   temperatures have warmed into the low 90s F across portion of the
   Mid-Atlantic. Coupled with mid-60s F dewpoints, this is supporting
   500-1000+ J/kg MLCAPE across the area, with further destabilization
   expected through peak heating this afternoon. Expectation is for
   ongoing thunderstorm activity across Severe Thunderstorm Watch 234
   to expand eastward, with additional development also possible along
   an approaching cold front. 20-30 kts of effective shear will support
   multicells, and perhaps marginal supercells. Steep low-level lapse
   rates (8+ C/km per latest objective analysis) and dewpoint
   depressions of 20-25+ F will promote the potential for damaging wind
   gusts, especially with any more well-organized clusters that
   develop. Isolated large hail may also accompany the most robust
   updrafts. A new Severe Thunderstorm Watch will be needed soon.

     until 900 PM EDT.

   * Primary threats include...
     Scattered damaging wind gusts to 70 mph likely
     Isolated large hail events to 1 inch in diameter possible

   SUMMARY...Scattered thunderstorms will develop and track eastward
   across the watch area through the afternoon and evening.  Hot and
   unstable conditions will lead to conditions supportive of damaging
   wind gusts in the strongest storms.

   The severe thunderstorm watch area is approximately along and 55
   statute miles north and south of a line from 35 miles northwest of
   Wilmington DE to 25 miles southeast of Groton CT. For a complete
   depiction of the watch see the associated watch outline update
   (WOUS64 KWNS WOU5).

   PRECAUTIONARY/PREPAREDNESS ACTIONS...

   REMEMBER...A Severe Thunderstorm Watch means conditions are
   favorable for severe thunderstorms in and close to the watch area.
   Persons in these areas should be on the lookout for threatening
   weather conditions and listen for later statements and possible
   warnings. Severe thunderstorms can and occasionally do produce
   tornadoes.

   &&

   OTHER WATCH INFORMATION...CONTINUE...WW 234...

   AVIATION...A few severe thunderstorms with hail surface and aloft to
   1 inch. Extreme turbulence and surface wind gusts to 60 knots. A few

No mention - just straight line winds where the most severe storms occur - which is yet to be determined BUT at the looks of radar and where the front is now central and south NJ along with Philly look to be most likely IMO

[NEG NAO]

click on fronts here and you can see the front is getting closer to us from the northwest already cleared NW Jersey - looks like areas south of I-78 get the most severe storms

94 will do it. Clouds moving in 

[psv88]

Looks like Islip topped out at 93 and FRG at 92. Decent 

[Cfa]

95 here, highest of the year so far.
