August 2015 Pattern and Disco

Recommended Posts

None of them have a cool HP building in from E canada. All show above normal..so the idea of a cool pattern mid week seems preposterous

 

What? I am talking about a front hung up south of us. GEFS argue cooler but probably near normal. EC is E-SE flow and ocnl showrs. You haven looked at anything.

Nice take on what should happen next week from ALB..That ridge means biz

THERE ARE HINTS OF STRENGTHENING UPPER-LEVEL

RIDGING THAT COULD CONTINUE THE 90 DEGREE WEATHER ACROSS THE REGION
WELL INTO NEXT WEEK. LOW TEMPERATURES WILL GENERALLY RANGE FROM THE
MID 60S TO UPPER 60S SUNDAY AND MONDAY NIGHT...

THERE ARE SIGNALS IN THE LONG RANGE GUIDANCE FOR LATE NEXT WEEK AND
INTO NEXT WEEKEND OF A RETURN TO STRONG UPPER-LEVEL RIDGING...WHICH
WOULD POTENTIALLY BRING SOME OF THE HOTTEST...IF NOT THE
HOTTEST...TEMPERATURES OF THE YEAR.

Glad we don't live there.

it's been doing this at that range for a long time... 

 

 

Just think of the bonanza of late middle and extended range stem-wound cyclones it will have come cold season - and the chirpy gaiety in the post flavor that seems to take place as a direct result of it every twelve hours...   Yet, it may be a month before anything really happens between times.

Gee Kev' ...surprised you didn't lube up this thread over the 18z GFS...  

 

150 thru to 360 hours, over 588 dm H the entire time... 

 

'Magine if that happened in early July?   Sun's still hot enough to do a lot of damage, but that's impressive either way...

 

Yeeeup, better hang our hats on this run -    :rolleyes:

# of 90 degree days at BDL over the next 30 days?. I'm going with 10.

I would take the under on that one. BDL has 110 summers in the climo record books, and from 8/16 through the end of the year, these are the top years by number of 90+ days:

 

1. 13 - 1983

2.   9 - 1973

2.   9 - 1953

4.   8 - 2010

4.   8 - 1961

6.   7 - 1937

7.   6 - 2009

7.   6 - 2002

7.   6 - 1991

7.   6 - 1959

7.   6 - 1948

 

This should give pause to anyone predicting a prolonged heat wave this late in the season even at a torch spot like BDL given that just getting more than 5 days of 90+ from 8/16 onwards is about a once a decade occurrence, never mind getting them to run consecutively in a long heat wave. Normal at BDL is 2.8 days of 90+ from 8/16-12/31.

6 out of the next 10 starting today because my post was written yesterday. 8/16-18, and 8/21-23 all look promising. If I get to 6 in 10, I feel that getting 4 out of 20 is feasible given the pattern. We roast.

Still a little concerned there could be some showers later next week if that WF hangs around with SE winds. 

 

It's interesting though ...that's really more of a vestigial feature than a warm front born of baroclinic differentials.   

 

General reader:  commonly referred to as "shear axis,"  these are sort of left over axis of different air movement, where the air on either side of said axis is homogenized(ing) and becoming the same.   They are interesting though in that they can wall off the hotter, tropical side when they pivot W-E like this one is currently modeled to do in the GFS and to varying degree/obviousness in the others. But, there is a sliver of continental fart that does razor into NW NE and as that settles thru on the N side of the shear axis, we get that low end heat-wave criteria air ... circa Sunday through Tuesday.

 

That part of the middle range has always been more clear, and not just because it is nearer in time - duh.  Afterward, there is a unanimous tendency for a much more pronounced subtropical/continental/WAR type ridge expression, but it's still too far out in time to count on much accuracy in the assessment of what that will mean to the dailies.  We've seen expressions intimating punishing 100 F type record heat, as much as mere mid to upper 80s with rich DPs, depending upon what permutations are in the flow that modulate and off-set this and that, what model and what model cycle...  Lot's of continuity issues there across the board.

 

The sun is still hot... but, not as such as it was on July 1. There has been triple digit heat into September to exemplify that, but in all of these/those late season events, things were nearly ideal - they had to be.  If the D9 Euro set-up transpired, than the detail of the 850mb temperature spread is probably even a tick or two higher, and that's the hottest of this summer slam dunk... But I don't have any faith in any such details, particularly when it comes to seeking ideal scenarios on a D9 chart.  

 

Just imo -

Kudos to Jerry - ? 

 

...seems destined to be warranted.

 

PRECIPITATION FOCUS WILL BE AROUND THE FRONTAL SYSTEMS EXTENDING FROM THE NORTHERN ROCKIES INTO THE PLAINS AND THROUGH THE GREAT LAKES... ACROSS THE SOUTHEAST AROUND THE SFC/UPPER HIGH IN THE WESTERN ATLANTIC... AND SOUTHERN AZ/NM. DETERMINISTIC MODELS SHOW THE POSSIBILITY OF A COUPLE INCHES ACROSS MINNESOTA AND SURROUNDING AREAS DURING THE PERIOD. TEMPERATURES SHOULD EASE IN THE WEST WITH THE LOSS OF THE UPPER HIGH AND CORRESPONDINGLY RISE IN THE EAST AS THE 594 DM ISOHEIGHT ATTEMPTS TO FORM.
