DP slightly lower this morning at 75. Currently 84/75 climbing from low of 77 after high of 98 yesterday, same as Thursday.

The gust front was insane. We were golfing by the lake yesterday and we’re approaching the green on 9. RadarScope showed the storms were roughly 10 miles out and looking to the west it looked like God took a massive leaf blower to the bunkers! We were putting easily in gale force winds and had to keep our sunglasses on due to the amount of dust. Coming back home you could visibly see the dust cloud to the east, just an insane amount of wind ahead of the line. Reminded me quite a bit of when sea breeze thunderstorms would hit in South Carolina, whenever you have those 90°/70°+ days it seems the outflow is amplified to the max. It flipped on a dime though, we had perfect conditions on 8

Well parade got cancelled. Disappointing but also understand why. We decided to put the antique together and do a quick march through the neighborhood for all the guys that never got the chance to pull the cart. We did three blocks up and back at 8:30 and when we got that done we were all glad the parade was cancelled. I think the city told them no parade. Roads are buckling in Chester County. Pottstown Pike in West Goshen is pretty nasty and this morning the Rt 100 Spur into Exton has concrete breaking up. Be safe today looks nasty later!

Going to preface by saying it’s only 9am but feels less humid with a light breeze and 82F

Lots of the Macys viewing areas are nowhere near a place to take shelter…. On the other hand you can’t cancel July 4th 250 fireworks lol

Seems less hazy this morning to my eyes. Sky is a deeper blue. Signs of the ridge weakening?

They've been consistent that today and tomorrow are decent days.

looks like few if any changes on the 13z SPC outlook

Wonder what you do if your Macys??? Tough decision

July 3rd cooled back very slightly. So, the DMI 80N+ mean Arctic temp still hasn’t reached 0C! The old record latest was 6/20/2013.

right now it looks like rain and scattered T storms after 6 pm today and that is no bueno as we plan on watching fireworks tonight and rain and lightning is not on my bingo card,,,,,,,,,,btw I hope you guys who lost power yesterday get it back sooner than later

Another 84 for a morning low at DCA, but whether this one holds through the day is more questionable than yesterday.

Hopefully today it actually is a bust, who wants this on the 4th lol and if so hopefully they’re quick like last night

Still 177K out according to the tracker - the vast majority being JCP&L. This has ended up quite serious for some communities - lots of people sitting in heat and humidity with no AC and once 24 hours hits, you start looking at a lot of food spoilage just as some freezers might be stocked for 4th of July. Hopefully there are cooling centers available. Stay safe.

The Colorado State model shows this.

I know it would mostly go to runoff but a 3" rainfall would be just I need psychologically Sent from my SM-S731U using Tapatalk

After 10:30 pm today it can let loose.

.95 in 30 minutes.

We call it flattening when they do that. Guessing it lets them cool off. We usually go through 100 peanuts a day and they are not eating much right now. I also saw some chickens panting which is not a common sight.

ONI of 1.0 is noteworthy this early. It’s on par with 15-16 and ahead of 97-98, 82-83 and 72-73. Even the RONI of 0.5 is impressive at this stage, most El Niños don’t develop until much later.

MRX re-introduced pops for today. Torrential rain with a storm that is just now winding down. About to go check the rain gauge.

Storms blew up east of I-81 yesterday late afternoon/evening and caused quite a bit of damage in various locations as I posted about last night. 31,000 people are still without power this morning.

84 / 72 heating up quick. Peak heat lingers the next 6 - 8 hours ahead of scattered storms tonight , still think many get their shows in and otherwise a great beach , bbq, pool day today. Sun - Tue - not so nice and a miserable period for outside / beach / bbq Sun / Monday wettest 1 - >3 inches of rain focused along kind of stalled out and hung up boundary (no surprise). Dries out and warms up by Wed - Fri with next shot at some starggler 90s in the hotter locations. Ridge pumps out west with weakness / trough into the northeast through the 14th. Beyond there ridge and heat expand east and moderation to a warm - hot pattern beyond there. 7/4 : Hot / Humid - storms - scattered 7/5 - 7/7 : Cool / wet storms rain totals upto >3 inches possible 7/8 - 7/10 : Near normal - warmer some hot locations could touch 90 7/11 - 7/14 : below normal / wetter 7/15 - beyond : Moderation to warmer / near-above normal , Heat signal as western ridge expands and heat comes east

Those higher probabilities should be adjusted N/NNE based on guidance
