    Seeing a lot of talk about a heatwave due to slowing global winds. He's an example 

     

    could you please repost this in the July thread ?

    ...which I find to be very useful.   Over the years, mere sight of these numerical values ...it's like "painting by numbers"   - in the mind, you draft very useful prognostic landscapes based upon what they mean and mean over time..etc... 

    The NAM is what it is in terms of either popularity or verification... but losing above would be a loss -

  3. 12z NAM has fully committed to positioning the warm front N of NH/MA border, tomorrow by 18z ..But it is in the process of diffusing in that position. 

    Up near Brian may have a late day high -

    Pretty impressive overall correction by the non-Euro cluster in favor of the Euro has taken place over the last 24 hours.  I recall mentioning to Scott I was on the fence at this time yesterday.  On one hand, climatology and years of scorn and sorrow at the hands of badly handled (models and man) BD air mass damming was too in favor of the GFS to ignore it.  On the other hand, the Euro was doing just that...completely ignoring, at like 2.5 days lead - a time in which it is seldom grossly wrong.  But ...in it's defense, it was different in the surface high pressure handling - in that it was more progressive in sliding it E out of the area faster.  This supplied less inhibition to displacing the warm front N... etc... 

    Don't mean to speak as though it's already all happened ...but it's pretty clear where this is destined.

    Yep. Easily.

    It'll by 88-ish at FIT

    Light W to WNW flow and all guidance blend of +16C 850s with sigma level ( typical cloud height) RH's modeled 50% or less is ample sun - under apex max solar no less.   Elevated launch temperatures as well because Saturday's been correcting warm and warmer, and that's high confidence at this point.  If anything, 2 or 3 clicks above machine numbers is safe.  Now...if these modeled metrics change, okay - but as of now..

    Folks are judging the day based on the cool feel now - this always happens.  Looking at a blizzard in the winter models when it's 55 degrees is a sure bet trigger for a cavalcade of neg-head downer posts about its unlikeliness.  But if in that moment the writer is typing it happens be -9 outside, the tenor in here is of course "too cold" and we'll end up too suppressed just the same

    what people want -

    I've found over the years of this social media's engagement ( as has everyone probably - ) that people lead with one sentence pot shot posts that they either know are wrong, or are of want so badly that they are molding analysis to conform to those desires.  they then sit back and gauge other's responses in some fleeting hope that they'll get a reply that supports their perception as actually being possible.

  6. Fwiw,  within margin for error, low grade heat wave in typical warmer climes ... like the CT R valley/ E of the ORH hills, is within reach on the 0Z MEX Mon - Thur

    Right now Wednesday falls shy, but I just get the feeling that we add a degree to that outlook ever day and find that it's really dryer DP thing, but still within T reach. 

    "Low grade"  as in 90 or 91, sub-advisory

    I’d like to see more of a trough into the Rockies like this last heat burst. I do think a piece could break off though. 
     

    Ridge builds more towards the Rockies and west coast around day 10, but then slowly retros so that it may open up the door to the Gulf of Mexico at the end of the 11-15 day. Note I’m just looking at the EPS. 

    As is ... sure.  

    I just would remind folks 10 days to two weeks back the illustration of the runs were torpid at best, and at times absent of the eventual destiny of a bigger ridge anomaly/heat. 

    However, looping - like watching them in cinema - conveyed a different suggestion. It's a situation where we could see another of these materialize, much in the same way ... coming out of an initial state where aspects are more vague.  But, doing so heading into climo, + CC attribution, + the fact that as is, there is a + thickness anomaly due to WV loading ( probably related to former) and lows are going to be elevated.  It's entirely possible to put up a top 10 or better July without even observing an official heat wave.  ...etc.  We're in a vulnerability for higher means...

    Maybe "possibly historic" is too strong for some people, fine - call it above normal. whatever

    You know ... any time and any place on Earth, since about 2002, whenever there's been  mere suggestions hinting at the possibility of above normal temperatures,  the return has been pretty dependable.

    Really? I see some ridging out west and a sort of meh pattern for us. Doesn't look extreme in terms of heat especially in comparison to recent stretch 

    The PNA in the telecon spread collapsed ...  

    These negative EPOs bursts during a PNA that is neutral negative ends up displacing westerlies S through the Rockies.  This is what precisely led to this recent heat.   I see vestiges in the behavior of the models as though that tendency is lurking.  For example, heights keep rebuilding between HA and California. 

  9. Saturday could sneakily become a low risk severe day ... 

    I think I see what's been going on - and the Euro may have been superior in this regard.  The flow's more progressive, and the high that is passing N of the region through tomorrow, is faster moving off S of the Maritime in the prior Euro runs than the GFS, which in delaying that departure ...yeah, it's mass fields are holding damming in longer...

    This 12z GFS run inched a little N with the warm front again - now between the Pike and Rt 2 at 18z.  Two runs ago it was near NYC

    But here's the thing, the Euro's front was ironically slower, and the GFS is now faster with the trailing cold front.  I don't think the lapse rates are good given this ( but haven't seen soundings...) but when you dawn with warm front escape, then have a cool boundary into western zones later in the day, that's a typical severe set up - in principle.   There's also a right exit--> entrance relay as a 500 mb S/W perturbation moves through NNE in the afternoon.

  11. 12z NAM looking more warm sectory in the grid:

    54006967438 01098 152008 72181814   
    60000985338 01796 121809 74211814

    That's a SSW wind at Logan, with 900 mb T to +18C   ...  100mb is +21C at 18z, which is probably good for 26 C in the 2-meter.  ALB and LGA are both +25C at that level, which is about 30 or 31 in the 2-meter. 

    We may have some still lingering frontal droop E of the Berk's but that's definitely more Euro suggestive.  

    Here's the NAM's synoptic representation at 18z

    I hear ya. I’ve been disgusted with the gfs lately. It was so bad for last weekend into Monday. Even 48 hours out. 

    Ha...You gotta understand ... I grew up in the 1980s and 1990s modeling arrogance - which means ...I was left heartbroken more than not.  That steady abuse of being gaslit by model solutions convincing us of a reality that would only prove fantasy, turned me into an neg nazi when it comes to situations where in one hand, it's what I want, and in the other, it's the looming reality that god is an asshole.  There's not a lot of evidence defending the latter, so ...we pick the model solution that best aligns with that principle and we'll always score remarkably well.  LOL

    IMO Euro is usually better than the GFS for damming. I'm wondering if it's more synoptics  that's an issue. If I'm wrong so be it, but I feel like GFS is too far south. 

    OH I'm on fence.  I'm just trying to objectively lay out the differences.  I did look at the 06z GFS and it trended N - that could be an early capitulation.  we'll see.   The NAM fwiw was Ner than it's previous 00z run...

    Skynet Euro looks like the op too. 

    I have seen maybe 3 times spanning decades worth of years ...whence the warm solutions won out over BD air mass lay-ins, and they were all in the last 10 years.   I don't recall specific dates, but there was one where all the models even the day before, had moderately well defined BD boundary replete with the whole 2-meter large T correction punching SW clear to NYC by mid day.    3pm rolls around it was still 88 in Nashua NH.  I was looking at the satellite, and there was no impression that boundary even existed anyway but there was a drape mid way up the Maine shore. 

    I think with models being much better, I have noticed that the improvement kind of makes them over-sensitive too?   - you know, 20 years ago, the models were never aggressive enough with these things.  Something like that.  I'm wondering if this one of those situations with the GFS just ending up too aggressive. 

    See ...even a crushingly mundane weather synopsis, there's something to be excruciating about  hahaha

  15. Euro for 18z Saturday

    image.png.f5291219b3953052798048337a49f515.png

     

    GFS ...

    image.png.fdd31cfc4135920d827ab1700e7abb7f.png

    We all know that the GFS is climatologically more sound than the Euro, particularly when considering the 24 to 36 hours prior to this 18z layout above.  Today's slab of Canadian polar air getting nice and jammed into the region does not typically displace by merely weak warm front momentum/kinematics - in acknowledgement of both theory and practic, the Euro is out to lunch. 

    on the flip side ... The Euro is seldom wrong this close.  It's an interesting little test here. ..

    I bet it's fine in most areas. Don't look at the gfs.

    GFS is wildly more pessimistic than the Euro for Saturday, mid day.

    Pick 'em I guess

    Nah BOS took the sensor offline. It’s still pulling previous data for the :54 ob I think.

    This is BOS though…not some shmuck airport like BML. It shouldn’t take 24hrs running in circles to figure this out.

    well, okay - we saw that, but I wasn't sure if it was a sensor malfunction or a ledger thing.   :blink:
