Very upside down month, based on the average highs for the first 11 days of August. Charlotte is nearly 7F colder than Burlington, Vermont, and 6F colder than Buffalo.

Onshore barrage / heavy rain there.  We had more like a California first week here dry / onshore.

8/12 - 8/18 :  Warm - hot / humid - Strongest heat Sunday/Monday
8/19 - transition day pending on trough/front   Erin approaches and hooks northeast Out to sea

The warm spots in NJ had 2 separate 10 day heatwaves back in July and August of 2022.  But you need to be west of the sea breeze front in NJ to open up multiple 10 day runs in the same season.

The last 20 day heatwave in NJ was back in 1988. So 10 day heatwaves aren’t that big of a deal for the warm areas.

But it’s very difficult east of the Hudson due to the enhanced sea breeze circulations in recent years. Plus the tree growth shading the NYC ASOS prevents 10 day heatwaves there.

You're correct. I took a look since 1970 when the current wetter regime (cyclical + climate change-forced) developed. August has grown wetter than any other month since then. Here are the per century trends.

It would be interesting to see how much 2011 skews that if removed.

64 / 53  losing track of the barrage of nice days.  Another beaut on tap   Mid - upper 80s, to 90 in the hot areas to start the heatwave.  Hot week , chance at some rain / showers, storms on Wed PM but it looks scattered, could be enough to hod back 90s in some spots.  Strongest heat is muted inland due to persistent onshore flow but dry period will enhance highs to beat forecasts by a degree or 2 in the hottest / sunniest spots.  Overall warm - hot / humid and wetter towards the 17th, Tropical activity.  Euro has strong heat (95+) and 850 MB temps >19-20c Tue - Fri.  Similar progression to this week perhaps.  Tropicalscs could reverse recent dryspell.
