Looking at the thermodynamic charts is a knife to the chest. We're sitting under 7.5-8 C.KM mlvl lapse rates and have already generated 2500-4000 J/KG of SBCAPE (we'll end up with widespread 3000-5000) and 2000-3000 J/KG of MLCAPE and should end up with 3000-3500 and LI values -5 to -8. This is about as unstable as you'll ever see it around here and it all goes to waste :( 

i dont understand why,is there a cap in place or something?

We are capped and we have no no forcing mechanism/ trigger to develop any convection. Even if we had something weak...with 700mb temps of +12C that is one helluva cap to bust. You would need some strong s/w to really bust that. A cap like this is even difficult to break out in the midwest

88.1F  Dewpoint 80.1F   I have never seen an 80F dew in my 35 years of living up here at 1100 feet. Wow!  Also with it being solstice and mostly clear I am running all 3 AC's on max and with the solar roof generating enough electricity to power the house and even sending some back to the grid for $ back.

12z MAV is an all-timer at CON

Be interesting to see what happens. Guessing for areas to exceed 100 we'd want to see their dewpoints mix to like 68 or 69? Just basing that off MOS/NBM and looking at dews for locations that are forecast to be above 100 and forecast to be like 98-99.

NAM 12z FOUS grid at Logan tomorrow, 18z

30000391714 -3499 132715 82 35 26 18

The last time I saw a vertical profile of temperatures like this ( they're in degrees C, from left to right corresponding to the 1000, 900, and 800 mb levels), was 36 hours prior to the heat wave in 1999 - which actually ... the next runs backed off.  

This was back when the NAM was not yet the NAM. It was it's predecessor known as the ETA. 

That 1000 mb T of 35 C is going to be 39 or even 40 C at the floor of the BL where explosive thermal overturning between the air and surface(s) constitutes the actual 2-meter temperature there.   In lay terms ... 39 ~ 102 and 40 ~ 104

Get out there and take advantage man! Go go go

Not sure I can get to 100F with these dews but good lord I can’t recall the last time I saw a dew of 81 imby. 

The funny thing is ... this would be more difficult ( I suspect ) if it were the July 20 variety.  

At this time of year, "geologically" we just walked out the door from spring rains climate and our shoes are still wet.  The grasses are all green and lush, and trees are all perky flopping leaves...   they are just dumping evapo -tran water vapor into the ambience at a very high mass load.  The idea? perhaps higher than later July when a month of summer desiccation has spend soil moisture bank account. These sources are less proficiently adding back to the air. 

I'm just wondering if July 20 is climate high temperature... but if the HI climate is actually a tad before that because we may get better combinations of DP with sun and source in the ends of Junes to something like July 10.

Yeah, that makes a lot of sense actually. These dews are incredible, seriously.
