July 2021

[uncle W]

my block got some thunder and lightning and a few drops from both storms...one to the north and one to the south...

[bluewave]

This is been one of the most persistent heatwave followed by heavy rain patterns since late May. We are currently in the heatwave phase. So we are on track for another heavy round of convection after this heatwave peaks.

Morning thoughts…

A very warm and humid day lies ahead. It will be partly cloudy and very warm today. Temperatures will likely reach the upper 80s and lower 90s in most of the region. Likely high temperatures around the region include:

New York City (Central Park): 89°

Newark: 93°

Philadelphia: 93°

Normals:

New York City: 30-Year: 85.2°; 15-Year: 86.3°

Newark: 30-Year: 87.3°; 15-Year: 88.5°

Philadelphia: 30-Year: 88.1°; 15-Year: 89.2°

Tomorrow will be partly sunny and hot.

Current temp 85/DP 69/RH 60%

[SACRUS]

84/69 and mostly sunny now.  If we maintain the sun - today should overperform on temps.  Same goes for tomorrow when 850 temps spike to >18c.  With enough sun we should see the warmer spots push upper 90s.  Saturday is a timing of the front on whether we can make more 90s.  Sunday front is slow to move through with more storms and rain continuing into Monday before clearing out.

Mon 7/19 - Thu 7/22 :  near normal, piece of the western heat may push a day of heat.  Beyond there next weekend 7/24 -25 looks to potentially have a candian cool (how cool can it go) airmass before a transition back to the warm to hot pattern.

 Can you explain to me how we're in a warm to hot pattern when through the 1st 15 days of July almost all reporting stations are between  -1 and  -2.5 including  Connecticut.  Maybe you mean Newark and central New Jersey  which still is not a hot pattern as most of those locations are around plus 1.

It's been a strange heart attack pattern of cloudy below normal days and showery days alternating with 90's never seen anything like it.

Yeah I think we need to update the terminology. By default it's always going to be warm to hot in July. 

Upper 80s to low 90s is not that far from normal. When I think hot I think minimum 95+ like we'll see tomorrow.

I think Philly's new average for the warmest part of the year is now 89.

That's why I don't think of 90 for 3 days as a heatwave especially for places like ewr

Sounds right..fits the progression up I 95. DC max normal high is 90 now, for most of July. First time they ever had a 90 "normal." LGA tops out at 87 (up 1 degree). Central Park tops out at 85, also up 1 degree. I remember the normal high at the Park used to be 86 though back in the 90s

I would think the heatwave alerts are more geared for health reasons and not meant to be defined for climatology reasons?

1 or 2 98 degree days can be much worse than 3 consecutive 91 degree days but would not qualify as a heatwave 

[Intensewind002]

87/67 right now, yesterday felt worse with the 75 dewpoint

[nycwinter]

does not feel as bad as i thought it would feel..must be diminished sun angle now that we are in mid july..

[RippleEffect]

Back to the island east Hampton area. Very warm day here with a temperature of 82 degrees!

[bluewave]

We have had so much record July heat since 2010, that the new 30 year climate normals have risen from 77.4 to 78.2 at Newark. So Newark only needs a +1.8 July departure for a top 10 warmest 80° or higher July. That’s why using departures can really underestimate heat in a warming climate.

The real reason may be Con Ed's desire to declare "Power Conservation" requests continuously by using an expected 3 consecutive days as the criteria.         Back in the 60's heatwaves were 5-Straight 90's around these parts.     With fewer AC's in use, Con Ed could handle it.     Naturally 3 straight days would occur more  often than 5 days.        Con Ed got the NWS (or was it still the Weather Bureau?) to go along with this reduction to 3 days by the 70's.            Dallas must use 3 or 5 expected 100's in a row, lest their whole summer would be  a HW etc..    

[Rtd208]

High for the day was 92 here.

Current temp 90/DP 72/RH 57%

[lee59]

Nice to see the southwest United States not having heat advisories. Phoenix expecting temperatures around 102-104 for the next number of days. Their average high is 104.

[lee59]

Hit 90 degrees here today, 8th time this season I have hit 90.

[bluewave]

Looks like the record heat will be focused over Montana next week.
