Color me shocked no thunder even close. 

I really didn't hear anything either, saw one flash of lightning, but that was it.  However, quite a few large branches were down around my area when I went on my walk today.

One thing we don't get to see back home is storm clouds like this. This was a pretty intense storm the other day in the Outer Banks.

Does anyone think with the relatively dry weather lately, we see increased heat during the rest of summer?  Or do you think the pattern will revert back to excessively rainy?

Looks really hot on the models starting the end of this week.  Multiple models had at least 5 days of consecutive 90+ heat.  The Euro had multiple days hovering around 95-97!  We'll see.

I do love this dry weather.  It doesn't happen much, so I'm savoring it.  Soon enough we'll be back in the rainy days.  The heat also hasn't been too bad, yes it is hot, but thank God the humidity has been fairly low.  I could get used to this, haha!

High of 95 on my station today.  I had to water the garden twice.  
I hear folks mentioning that this reminds them of summers past while growing up.  Growing up north of Pittsburgh in the 60’s -70’s timeframe we didn’t have A/C until I went off to college.  We somehow managed sleeping upstairs with just window screens and a few fans.  If it got too hot I remember sleeping outside on the front porch, but very rarely.  My recollection was the grass browning during mid-summer dry periods, but not long periods of heat like this.

Mesoscale Discussion 1174
   NWS Storm Prediction Center Norman OK
   0311 PM CDT Fri Jul 10 2020

   Areas affected...Eastern Kentucky...western West Virginia...Eastern
   Ohio...and far western Pennsylvania

   Concerning...Severe potential...Watch unlikely 

   Valid 102011Z - 102145Z

   Probability of Watch Issuance...5 percent

   SUMMARY...Strong to occasionally severe storms are expected to
   persist into the early evening hours. Damaging winds remains the
   primary threat.

   DISCUSSION...Several rounds of storms have moved across most of Ohio
   and northern Kentucky this afternoon with scattered wind damage
   reports. A few severe wind gusts have also been reported. Expanding
   cloud cover and convective overturning has cooled the boundary layer
   across most of the region and thus instability has decreased. In
   addition, dewpoints decrease significantly in central Pennsylvania.
   Therefore, the cooling boundary layer farther west and the lower
   moisture ahead of the ongoing activity should lead to gradual
   overall weakening of these storms. However, there are still a few
   pockets with upper 80s to lower 90s temperatures in eastern Ohio,
   eastern Kentucky, and eastern West Virginia where strong instability
   will still be present. Therefore, a few strong to severe storms are
   still expected into the early evening hours.

Finally got a good soaking rain today. It’s been interesting seeing the storms find different ways to dissipate before getting to me this week. Today appears to be no different but at least managed some rain.

Lawn was starting to look like mid August than early to mid July with how brown it is.

Case in point, watch the line just dissolve. Must be something to do with terrain as this happen pretty frequently year round, although today is partially plagued by some rain earlier that probably stabilized the atmosphere.

Only got 0.17" yesterday...better rain so far today, slow soaker but light so far.  My immediate area seemed to be constantly missing the heavier downpours.  I've never seen cool season grass look so  dead brown in my lifetime.

There were some odd dead spots even here south of Downtown.

 In real time yesterday the radar didn't really show it, but there were some noticeable differences in amounts within a relatively small area.

   NWS Storm Prediction Center Norman OK
   0251 PM CDT Thu Jul 16 2020

   Areas affected...Northwest OH...Western PA...Northern WV
   Panhandle...Western NY

   Concerning...Severe Thunderstorm Watch 378...

   Valid 161951Z - 162115Z

   The severe weather threat for Severe Thunderstorm Watch 378
   continues.

   SUMMARY...Threat for strong to severe storms capable of damaging
   wind gusts and a tornado or two continues.

   DISCUSSION...Broad surface confluence within the warm sector
   continues to promote widely scattered thunderstorm development.
   Temperatures across the region have warmed into the mid 80s in the
   warm sector, with recent mesoanalysis estimating between 1000-1500
   J/kg of MLCAPE. Enhanced low-level flow stretches across the warm
   sector, which is also along the southern edge of the strong
   mid-level westerlies. Consequently, effective bulk shear decreases
   from around from 40-45 kt around the western PA/NY border vicinity
   to 30 kt across western OH. These conditions remain supportive of
   strong to severe storms. Primary severe threat continues to be
   damaging wind gusts, although a tornado or two also remains
   possible.

Interesting record we're approaching in Pittsburgh.  Looks like as long as the highs hit 80 through Friday, Pittsburgh will have hit 80 degrees all 31 days of July.  Checked the NWS page and found that this would be the first time since 1955 that has happened, and only the 3rd time in Pittsburgh weather history.  The other time being 1878 (before the reporting site moved out of the City).  Pretty impressive.  Plus, this would only be the 3rd month to ever have all its days reach 80 (August has only gotten to 30 days).

   Areas affected...eastern Kentucky...much of Ohio...much of West
   Virginia...and far southwestern Pennsylvania

   Concerning...Severe potential...Watch possible 

   Valid 011819Z - 011915Z

   Probability of Watch Issuance...40 percent

   SUMMARY...Deepening convection will pose a risk for damaging winds
   and perhaps a tornado or two through the afternoon.  A WW issuance
   is being considered.

   DISCUSSION...Convection across eastern Kentucky has gradually
   deepened and intensified over the past hour, partially in response
   to lift/ascent associated with a mid-level low over Illinois.  These
   storms are in a moderately buoyant airmass (1500-2500 J/kg MUCAPE),
   with deep shear of around 25-35 knots marginally favoring loose
   organization.  Weak low-level flow also favors outflow dominant
   storms, though some turning/veering with height may support
   occasional updraft rotation in persistent, cellular convection.  An
   east-to-west oriented warm front located from near DAY to near MRB
   may also aid in updraft rotation with cells that can favorably
   interact.  The overall scenario suggests potential for occasional
   wind damage and perhaps a tornado or two with stronger convection. 
   The nature of the threat may become substantial enough to require a
   WW issuance over the next couple of hours.  Convective trends are
   being monitored.

Anyone else notice a lot of leaves changing and falling already?  I assume it's due to the dry and hot conditions lately, but still a bit odd to see leaves dropping in brown and orange on August 4th.

We always talk about the Western Pa. screw jobs for snowstorms each Winter.

Check out this Summer Thunderstorm screw job map.

That's a screw job I'm ok with, lol!  Now in winter, with snow, it's unacceptable, ha!

Haha this would be too typical in the winter, but it also feels like this is the way summer is going too. I wish there was a metric to determine how much thunderstorm activity we’ve had this summer. I know it has been try, but I feel like we’ve really lacked those nice afternoon boomers as well. Maybe just me in the south hills?

I actually just thought last night, looking out at the sky, there has been a remarkable lack of thunderstorms this year.  I don't remember this few storms here.  Very weird.
