I thought the BOS record was 25 in 1988/2010...I guess I was wrong. Didn't realize 1983 was so ridiculous. Or 1955.

Is that one summer or 1 year back fr a given date? 1955 sea suspect although I remember the fact that we exceeded 100 at the old Battery obs station and that was rare then.

Its for the year (which pretty muchmeans the summer except it would include any days >90 in September/May/April too)

 

1955 looks like this for # of 90+ days:

 

June: 4

July: 14

August: 9

September: 1

 

Total: 28

 

 

BOS hit 100F on 8/5/55.

GFS hinting at more oppressive humidity late next week as well. At least we get a brief break early to mid next week.

 

Yeah, this is what I am afraid of ....  I don't really see a "pattern change" taking place; more at a relaxation episode in the subtropical ridge strength, regardless of whether it be continental, or WAR -- though lately it has been the Bermuda retrograde action that has proclaimed WAR on the beleaguered civilians of the East Coast. 

 

I was mentioning this to Scott or Will last week that we've been in a pattern that features cyclic warm to average departures ...~ every 3 to 5 days.  Ridge roll-backing has delivered midland heat criteria, prior to episodic 80W trough/geopotential weakness, that have allowed now for two, 2-day intervening periods of average temp and DPs between said warm days.  

 

Judging by the larger -scaled circulation construct I don't see that what has giving rise too all that, has changed.  It is difficult to use the NAO outright at this time of year, but of the remaining indices, it's about the only one that's correlative at this time of year, and it's flattish ensemble mean, while operationally the GFS still rolls negative nodes through D. Straight and the middle Maritimes, does teleconnect to heat along the MA -- so seeing ridge tendencies to return fits the current pattern and that signal, combined.   

 

There's all that, and Forky' and I have noted a tendency for some of these higher resolution global models to carve heights too prodigiously over SE Canada. Prior to all foresaid intermediate cooling periods when in the operational runs ... particularly the Euro and GGEM, went way over-board.  In fact, the GGEM was spinning up nor-easters.  

 

So, all in all, I'm a bit more confident at staying the course and figuring that we get a couple of days of reprieve and then either the WAR rolls on back again, or the heights just stay N to some smaller anomaly, but enough to get some kind of heat back in.

Great disco Tippy.

i don't know how it can't be considered a "pattern change" 

 

we will go from record high heights over the OV to a mean trough position in that exact location.

I remember that summer, and the news headlines as PHL-NYC-BOS were very streaky with heat.  Thing is, the heat wasn't overbearing much of the time, but it was 89.9 for days on end.  ...hyperbole, but you get my drift.

The point is, the "pattern" at large, is allowing for 3 to 5 days of warmth, followed by a ridge relaxation...then it all repeats.

 

THAT is the pattern.  

 

A profound and meaningful pattern change would break that periodicity down in lieu of a new paradigm.   

 

That could happen ...sure, but I don't see that signaled at the moment.
