Will begin thread around 725A featuring potential for SVR storms north of I80 late Tue, especially late Wed, and heart of the forum Thu and southern edge Fri?  Looks to me like Danny vort gets involved Thu-early Fri per tracking remains on RAL and op cycles. Iso FF possible Thu-Fri per WPC D3 excessive.  Remembering all the cycles prior to last Saturday of 4-7" by July 5,  we shall see.  Not thinking of adding July 3-4-5 since opportunity for the bulk of the RW+ slipping just south of us - but could be close for the southern part of the forum.  

SPC D2 SVR northern part of Forum (I80) north,  D3 Marginal throughout.

Thread in an hour or so. Gotta walk the dog in the cool 73F air.

This  was the strongest 500 mb ridge on record for the month of a June in our area. The 597 dm height was also very close to the all-time record for the entire summer. So a continuation of the extreme WAR pattern of recent years. But the February 2018 record that produced the 80° all-time winter and February record high is still the greatest excursion from climo.

Morning thoughts...

After a warm night with low temperatures starting near or at daily record high values, today will be variably cloudy and hot. There could be a widely scattered afternoon shower or thundershower. Temperatures will likely reach the middle and upper 90s in most places today.  Likely high temperatures around the region include:

New York City (Central Park): 94°

Newark: 100°

Philadelphia: 95°

Normals:

New York City: 30-Year: 83.4°; 15-Year: 83.6°

Newark: 30-Year: 85.7°; 15-Year: 86.0°

Philadelphia: 30-Year: 86.8°; 15-Year: 87.2°

Daily Records:

New York City-LGA: 98°, 1959 and 2012

Newark: 100°, 1934 and 1959

Much above normal temperatures will likely persist through tomorrow.

The extreme heat that has been melting all-time high temperature records in the Pacific Northwest will ease its grip on Oregon and Washington as it moves further to the north and east into Canada. Parts of eastern Oregon, Washington, British Columbia, along with Alberta could see numerous record high temperatures.

On track for 100 today at the local warm spots. The lows at EWR and LGA were near the all-time June record warmest. With low 80s already by 8am, somebody may go a little over 100° to challenge the all-time June monthly high temperature.

As these urban areas continue to grow, the night time summer temperatures will continue to rise.

These urban areas are fully developed…there is no open space around Newark…

Like Queens and Brooklyn, I agree they're fully developed but that doesn't stop them from tearing down and putting up bigger and bigger skyscrapers

I don’t think that impacts the ASOS sights. Most of the new buildings are “green” and as for Queens, the exteriors are all glass, unlike the older buildings which were all concrete which holds in the heat…

Heat is on and only looks like a break between next surge of ridging / heat.  Mid / upper 90s today and tomorrow, perhaps 100 in EWR / LGA, may be close.  Pop up storms possible later and more chances Wed.  ECM and GFS now bring front through on Thu - Sat with cut off low staying west of the area and brining shower/ storms Sun (fourth).  Still have to work out the timing but the RIdge is stubborn and that means extended unsettled weather 7/1 - 7/4.  Not sure its a complete washout Sunday but looks very unstteled.

 

Beyond there the heat returns next week as ridging and heat from the heat factory in the rockies  and northwest traverses east.  More 90s by Tuesday (7/6) with 850 temos >16 - 18C.
