Currently 85 here and swamp ass muggy under partly sunny skies.
Full clearing now moving SE quickly from NW Sussex County. Should be totally sunny here within the next 60-90 minutes.

Based on latest radar / satellite not expecting much sun until 1:00 P.M. or so. Forecast highs in the m/u 90's going to take a hit. Best case is low 90's late afternoon in the hottest spots? Going to be hot and humid no matter later on.
Just light showers and few rumbles of thunder here so far this morning but that is one thick cloud deck. Been extremely dark since around 8am. Per radar heaviest rains and possible severe mainly over NEPA.
Think valid concern especially in the large inner cities and especially with the elderly with minimal resources and support systems to get them to safety. Overnight lows and associated HI readings will be brutal if not prepared. Would not be surprised to see HI readings of 110 or even a bit higher at some point during this hot period. Think most max temperatures top out in the 97 - 102 range but with dews in the m/u 60's to near 70 it will be beastly hot if no a/c, again especially in the inner cities. Believe all warnings justified and hopefully cities will open cooling centers starting tomorrow.
Tuesday for sure looks like the worst of it area wide.
Offset to this will be higher dews. So while EXTREME temperatures are pretty much off the table some nasty HI readings and sultry overnights are upcoming. Max HI 105-110, maybe a little above that (112?),
Hopeful for at least some brightening if not breaks in the clouds later this afternoon. What a run of weather for mid June.

In my opinion this is going to be the bigger story. High HI readings. DP's in the upper 60's and low 70's along with 95-100 degree temperatures not pleasant. Lot's of bed wetting going on with EXTREME max temperature forecasts. Dubious outcome on that, especially this far out. Interesting to watch for sure but you could be disappointed. Will be nasty combo of temperatures and dews though. Heat related advisories and warnings will be flying down the road. High dews will make for miserable warmth urban areas during the overnight hours as well.
Love this post. Measured and level headed. I am wary about temperatures peaking much over 100 myself, especially this far in advance. As Walt stated much can interrupt and it has been quite wet lately. Bigger issue for me will be HI readings possibly 105-110 with higher than usual dews possible for a W / WNW heat event. We'll see but high temperatures of 105+ are very suspect to me.
And on it goes this morning. Had light rain, mist and drizzle all day yesterday. Pea soup fog ongoing this morning. Seems temperatures at my location have been stuck between 58 -62 degrees for days. Rainfall totals since last Friday = .28"/.36"/.07" and .23". Total = .94".
Like the idea that the recent rains here and over a large extent of areas to our west and southwest keep the dews up making the upcoming heat more oppressive. Also like idea that recent rains here and possibly a 1" event before the heat arrives keeps max temps a few degrees lower than what they could be.. Either way if you like it cooler enjoy what we have now.
