Last 2 days of guidance have consitently forecasted the WAR to build in stronger than what previous runs were showing for the 7/1 - 7/5 period . This will create a deep tropical fetch on a strong southerly flow with higher heights along the coast and a trough in the Lakes caught between the moster west coast ridge and WAR.  We should see overall warmer than normal temps with daytime highs in the 80s with warmer lows and very humid conditions with DT's in the upper 60s/low 70s or higher.  Outside chance of 90 degrees on the sunnier day(s) with  850 temps still projected in the 15c - 20c range, but plentiful clouds will limit that kind of heat.   I think once past Sat its more daily scattered showers (with some soakers) rather than widespread rainouts that we may experience later thu into saturday.  Still, these scatered Florida-like storms could yield some hefty totals the between 1st and the 5th.  

 

 

Beyond there seems that the flow flattens a bit and we may see a spike of heat on/around 7/6 into the week of the 8th.

The 18z NAM has continued to shift the axis of heavier rainfall south and now makes Thursday afternoon and night pretty much a washout based on high res sim radars from the city on west.

 

Early Saturday is dry until the moisture moves in during the early afternoon from the south.

 

4Km NAM keeps most of the "washout" stuff well west of the city.

While this whole deal of storms moving to my north and south virtually every day is rather comical, I do feel like it could get old very quickly if I still don't see at least a nice CG stroke or something by the end of this week. 

 

There has been a significant thunderstorm drought here ever since mid April

Looks like a few hours of sun and some late afternoon highs.  EWR at 86.  Some may be able to get the heatwave some have already with some 90 degree readings on Sunday. 

Sunday highs :

 

TEB: 91

NYC: 88

EWR: 89

LGA: 87

JFk: 80

ISP: 82

New Brunswick: 88

TTN:  86

ACY: 83

PHL: 85

Only one spot officially hit 90 Sunday.

All areas hit 90 + Monday and yesterday.

Many areas did not hit 90 today so no heatwave for most areas that count.....FAIL!

Is there any chance that Saturday could have bright times with sunshine with just the afternoon and evening storms with some drying Saturday night with some breaks in the clouds between 6:00pm and 9:00pm?
