Partly sunny SW of ORH from late morning ion with the jet screaming at 6,000 feet . There’ll be 40-50 mph gusts inland with mixing where sun pops

I knew you would find some reason to dismiss. My stability assessment is based on comparing Coatesville to NCEI and other regional stations without station changes. Coatesville tracks NCEI closely. Yes there are three stations; but, the three stations are well matched for annual average temperatures; and, there are no major station changes. You would get the same answer if you used NCEI instead of Coatesville.

Because it is where I live....LOL!

why does chester county matter so much

llvl lapse rates may be steep enough to support gusts 35-40 mph inland. Also, the lack of rain farther inland and even potential for some cloud breaks may allow better than expected mixing (evident by the steep llvl lapse rates)

All models give you at least. .11

Some of the modeling has 35-40mph gusts down there in ORH county. But this is obviously anomalous and dynamic for this time of year. It does give me 2013 sensible wx vibes for NNE though…albeit a different evolution.

Last night's Blue Origin Rocket explosion on KMLB Radar between thunderstorm complexes to north and southwest.

I'm not expecting much for winds in central Mass... breezy sure, but nothing super unusual... further east (esp coastal NH and ME) could be fun

I think it would favor more -NAO events going forward (decadally). Be careful that you are calling the -AMO right now is not from a lot of +NAO/+AO, especially in the warm season. Immediate term the central-south Atlantic has -0.3 to -0.4 SSTA correlation with +NAO conditions. I know, correlated immediately, inverse in the long term.

I will be spending 10 days in June with a much colder view...going to Alaska June 7-17! Bucket list trip.

Diurnal range today is going to be off the charts here.

We will torch late summer into fall/winter

i’ll kick it off with a current view…

Well, it's all connected...sure, the RONI only measures the oceans, but I think the warming oceans are somewhat connected to the more pronounced 500MB ridges....I think there is an element of feedback at play. Bottom line is there is more heat, which is being reflected in the ocean and the atmosphere, but it just so happens that the RONI only measures the former...so technically, yes...it certainly goes beyond the RONI.

Yep, if it’s going to be dry and boring, may as well be 80 and dry/boring

I think that it could also go beyond the RONI in that the 500 mb ridges are expanding in the mid-latitudes outside the tropical oceans which RONI measures. The 500 mb ridge across the North Pacific from east of Japan to south of the Aleutians has been unprecedented during the 2020s. Also note the slightly weaker mirroring of the pattern in the South Pacific to the east of New Zealand. So it’s been warming the SSTs underneath the ridge causing the -PDO to remain negative. In the old days ,the -PDO was more a function of colder SSTs off of California rather than the extensive warm pool from east of Japan to south of the Aleutians that we have today.

So what does that look like in terms of surface winds? I'm in central MA and trying to figure out if I need to protect the veggie garden plants.

Dry and partly cloudy here tomorrow while it pounds rain S Wey to Pope

Also posted on the thread just made for this upcoming storm. Interesting what the 12z HRRR shows. It has a very high QPF max of 5.77" over SW ME. Other models do not show this, but sfc low is a tight SUCKA and I wonder about mesoscale factors. SPC has general tstms outlooked and convection stirs things up better aloft. This results in stronger downdrafts to mix down the cold air aloft better. 850 and 925 mb temps are cold enough by 12z in this area and that kind of pcpn intensity? The ante is very high here! Can you imagine on the coast w/ super paste and G50kt? I'd love to be at Hampton Beach Sat AM! The reason the HRRR shows this big pcpn max in SW ME is b/c the area is at the pivot point of the N side of the comma head, so they cash in w/ a heavy pcpn area nearly stationary in a relative sense. Such a scenario is not unreasonable and the global models would not pick up on something like this. So we may have two pcpn maxes, one over the White Mtns and another coastal ME/NH. Look at the HRRR sim radar late this eve/very early Sat over NH/VT, TRW+ FQT LTGICCG surprise before the S+??? This is about as good as it gets for the uncertainty factor for big S+ and "PHUN 'N GAMES!" Scott should be impressed! Could be a truly exceptional event. Big snowfall like this so late (higher and lower elevations)? You have to go back to the 19th century (1816 and 1842 in June) for anything later. MWN had 24.9" in the May 25-26, 1967 event and they could exceed that for the May single storm record.
