With all the heat and high dewpoints, no mention of a heat advisory?

They are kind of quiet this morning.

67 for the low.

CTP mentioned this morning that the SE counties will see Heat Indexes approach 100 today...the criteria for an advisory being issued is over 100. I suspect that the LSV will see advisories tomorrow and Wednesday. 

Also - they used the words "fall like weather" when looking ahead to the end of the week.

Unfortunately, it also now appears that flood concerns are elevated on Thursday:

.LONG TERM /THURSDAY THROUGH SUNDAY/...
Models show t-storms accompanying the southeastward moving
front through CPA on Thursday. A wave of low pressure is now
progged to move along the boundary, which has trended slower
with its southward/southeastward progression. There also appears
to be some enhanced large scale lift to support +RA in the form
of right entrance region (RER) upper jet dynamics. High rain
rates combined with ample deep layer moisture will continue to
support an excessive rain/flash flood risk particularly across
the southern tier of CPA on Thursday/D4.

The slower southward movement may also delay north to south
clearing, and we can`t rule out a stray shower lingering early
Friday morning in southern tier/far southeast PA. That said,
much of the area will be firmly in the dry/cooler sector by
Friday afternoon.

Behind the front, a comfortably cooler and refreshing airmass
(much lower humidity) is poised to arrive just in time to begin
the month of August. Slightly below average daytime highs
70-80F and lows 50-60F are forecast along with no rainfall through
the first weekend of August. Dewpoints will plummet into the

The southern tier again.

I joked about it in yesterday's video (not uploaded yet) about how someone sprayed storm repellent over the eastern coal region, and how most of the big storms are south of I-78...lol

Most spots will see the start of Chester County’s  2^nd “heat wave” of the summer season. Today through Wednesday should see highs topping out in the low 90’s each day. Today could be the exception across the higher ridge locales with highs a degree or two short of 90. A strong cold front will start to cross the area by later Wednesday night with shower and t-storm chances increasing and signal a nice change to below normal temperatures for next weekend. Below normal temperatures look likely for at least the first week of August.

Very nice, looks like a cool little spot.  Always nice to escape the heat up that way.  Go another 10-15 miles north and you'd be at my buddy's cabin.  Have fun!

 

Congrats on the grandson!  That has to be so exciting to get to relive those phases of life.  The years really do fly by, still can't believe ours are already 3 and 5.  It's amazing and sad all at the same time watching them grow up.  It just swells your heart.

Hey bud.  Thanks for the kind words.  Got in to see little J (Jace) friday night and yeah, the emotions and life really comes at you hard when you see your son holding his son, then you get to hold your grandson for the first time.  Great stuff.

Embrace the little things, and even the not so fun things, because in the blink of an eye, you'll be looking back wishin for them.  Kids had some hiccups last week, but J, momma and my son got home on Saturday.  All is well.

Looking forward to the end of the week respite from swamp ass.  Its been nasty.

Im not sure why the NWS has me tallied for .01 last night.  We had a 20-30 minute gully washin deluge that was on par for the hardest rain of the year...and we've see a ton of it.  easily .75-1.0 shoulda been recorded in the rain bucket.

I'm hoping to be on the mountain or road bike tonight.  We'll see.

I had a grand total of .26" of rain for the entire weekend. I was fringed or missed in every direction both Saturday and Sunday. (I got nothing yesterday, not even a drop)

My pal lives in Hopeland (couple miles NW of Ephrata, and they got almost 3" saturday night as well.  We got hammered saturday as well, but not 3".  Crazy how popcornish/localized these rain events have been.
