80's during the day and 60's at night is going to feel "cool" after this week.

 

The 12z GFS keeps things wet and unsettled from the tropics up the east coast. It's pretty easy to make out where the ridge axis ends up based on QPF placement over the next 2 and 1/2 weeks.

It looks convective once we get into the return flow around the Bermuda High later next week again.

Lol thats exactly what was said about this week two weeks ago and lots of faces with egg on them

It was pretty clear that around the 4th of July the WAR was going retrograde west for an extended period of time, and then weaken. By next week we're going to be stuck between the ridging over the plains and the WAR.

The WAR could very well retrograde back westward after this week, but that point is very much up for debate. CFS V2 keeps the WAR far enough east going forward to only impact coastal New England with above normal temperatures. In fact, it depicts mostly near to slightly below normal temperatures from this weekend through the middle portion of August. Other ensemble guidance supports this point view. It is not uncommon for certain features to remain in place throughout the summer season, but they could vary in placement as well. Keep in mind much of the Mid-west and Southeast is having a cool to very cool July thus far. A slightly further east displaced WAR could put our area in that corridor of normal to cooler temperatures.

My thinking at this point is that the mean trough shifts into the Lakes/interior Northeast for the July 20th-August 15th period overall. Generally a regime in which heat (90+) will be limited in our neck of the woods, with plenty of normal temp days, even occasionally cooler than average. I believe strongly that the WAR will retrograde west for the late August-September period however, potentially delivering a very warm/humid late summer/early autumn period. ECMWF drives the MJO into phase 2 over the next 7-10 days which will get the ball rolling toward more troughiness in the Lakes/Northeast.

That was one of my thoughts for August. A setup like that would put us in the danger zone for tropical activity.

 Yea with the WAR just to our east we would be in a possible shooting gallery for tropical activity

And with water temps as warm as they are it could be quite interesting

Sounds reasonable for the next week as the weakness in the ridge/any trough should bring temps closer to normal.  But I suspect the trough migrates over the Lakes and we warm things up towards the middle/end of next week with a more humid flow.  Agree that it's more limited heat (90+) through the 27th.  Thereafter there are some clear hints that the WAR builds back west and even a chance it hooks witht the Western ridge.  Also seeing some of the blowtorch heat that has been bottled west coming out east as we end July..  I think we remain in an overall above normal pattern through the 27th with some stronge heat beyond there and into the start of August.  Of course within the 20 - 27th period  we could see some cloudy more wet days that could yield a few degrees below normal.  It will be interesting to track.  ECM MJO was advertising the same the middle and end of June for July so not sure how well thats working this summer.    Top 10 or even 5 hottest July for many looks in the cards.

The combination of the mostly positive NAO and AO with the WAR has been a tough hand to beat since April. Patterns have been really locking in for the duration the last several years.

The sandy hook buoy (8531680) has a water temperature of 82, we usually peak around mid August to mid September. Hopefully with the warm SST's and a persistent WAR we can have some tropical fun in August/September.

Don't think anyone on the coast wants tropical fun

Not to be insensitive (especially since your house was damaged) but I'd absolutely love another hurricane, maybe if what I wished for dictated the elements I'd be more careful :)

Thanks Unc.  We came close last June (6/21)  low of 79.
