Kind of looking like one of those NJ to NYC potential flash flooder.

NAM going wild over PHL to Western NJ with big rains 4-6 inches

Actually some good llvl dynamic cooling on the NAM

I suspect that its urban heat island grew since the 1960s-1970s.

On the northern edge of the precip up here, Meh.

91/68 HI 95 Hot, but dews aren't atrocious today

average temps start decreasing in august.

I should complain more. Nice bump north on the 6z euro and 12z NAM. We take.

Nice good soaking. Could be a solid damaging wind event across Maryland and Delaware tomorrow.

Well, appears the AI models need some more teaching and learning before they can predict tropical storm and hurricane formations. Andy Hazelton @AndyHazelton 1h Central Atlantic waves are pretty convection-free at the moment, as background stability and dry air suppresses rising motion. Not surprisingly, there isn't much model signal for development anymore - the AI models seemed to have been overzealous. For now it seems like physics-based models (e.g. GFS, Euro, and their ensembles) are still our best bet for sniffing out potential TC formation.

Good widespread rain anyways for many.

Did i miss the hourly temp maps this morning?

Today should be our last 90-degree day for at least the next 10 or so days. We will see rain chances ramping up tomorrow afternoon into the evening with a cold front. We could see at least an inch of rain in many spots across the area with showers lasting until Friday. On Friday night we see some autumn like weather arrive for the weekend. Highs mostly in the 70's with lows in the 50's. Below normal temperatures look to continue through much of next week.

We've had only 2 heat waves in our 27+ years here, and 8/13-15 is one (other is 6/25-27/03). August 2002 had an 8-day run, 11-18, that had an average high of 89 with each day at 87-91. Wasn't too humid as the lows averaged 58, but our car's AC had conked out (at 204k miles) earlier that month. Then 9/9-10/02 reached 93/92. Since then, we've reached 90 eleven times but none later than June 28 - 2 in May and 9 in June. Odd distribution; maybe the taller dews and busier trees of mid-late summer have held down the max temps.

There's a pretty prominent heat signal showing up for parts of the East during the week of August 11-18:

why is LGA over 8 percent higher-- is that because of much more traffic and higher population density in that area now Don?

unfortunately JFK is fairly unchanged =\ Don could you please do a similar rundown for 95 and 100 degree temperatures too? Thanks!

wow two separate 99 degree heatwaves in July and August? thats like all the pain without the reward of a triple digit high at least 1983 (which was a hotter summer) hit 100 both in July and August at JFK and 99 at Central Park in September

that would be crazy a midnight high of 90....

A day later and the purple is back.

1993 and 2010 way ahead of everyone else, just as I remember them :-)

Weatherbell that was 00z.. 6z just got released since I posted that which is much less with that in mind it flops like that NAM and hrrr so take with a grain of salt
