not if this is right.

this on-again/off-again thing is getting old but this run looks very very warm late next week

nah, doesn't last all that long. This run is hot for 1.5 days then cool for 2, pretty much as a general theme right out to la la range.

it's an absolute furnace friday/saturday of next week. who knows how it'll actually shake out but it's very hot.

i don't know if this will mean anything but it's a good thing it is not winter... The only way the ECM gets away with those trough incursions is because the wave lengths are so shortened at this time of year. If the wave lengths were stretched to January tension than that ridge in the heart land would expand ENE - obviously not as 590dm heights but you get the drift.

Didn't ORH come in last year with an overnight low of 80 or was that subsequently changed ? I do recall ORH_wxman vehemently challenging the accuracy of the reading.

The highest min I see from last summer is 77F. I do remember how out of whack that 80F reading was though compared to all the hilltop mesonet stations including where I was at winter hill.

while we bask in Canadian glory:

...EXCESSIVE HEAT WARNING IN EFFECT FROM NOON FRIDAY TO 7 AM CDT

TUESDAY...

...EXCESSIVE HEAT WATCH NOW IN EFFECT FROM TUESDAY MORNING

THROUGH WEDNESDAY EVENING...

THE NATIONAL WEATHER SERVICE IN OMAHA/VALLEY HAS ISSUED AN

EXCESSIVE HEAT WARNING...WHICH IS IN EFFECT FROM NOON FRIDAY TO

7 AM CDT TUESDAY. THE EXCESSIVE HEAT WATCH IS NOW IN EFFECT FROM

TUESDAY MORNING THROUGH WEDNESDAY EVENING.

* TEMPERATURES...AFTERNOON HIGH TEMPERATURES WILL REACH THE LOW TO

MID 90S FRIDAY AND SATURDAY...THEN THE 95 TO 100 DEGREE RANGE

SUNDAY THROUGH WEDNESDAY. SOME AREAS COULD TOP 100 DEGREES AT

TIMES SUNDAY THROUGH WEDNESDAY. THESE HOT TEMPERATURES ALONG

WITH SWELTERING HUMIDITY WILL PRODUCE DANGEROUS HEAT CONDITIONS.

* HEAT INDEX...HEAT INDEX VALUES ARE EXPECTED TO RANGE FROM 105 TO

112 DEGREES EACH DAY...WITH OVERNIGHT HEAT INDICES ONLY COOLING

TO AROUND 80. THE HIGHEST HEAT INDEX VALUES WILL ARRIVE SUNDAY

AND PERSIST INTO NEXT WEEK.

* IMPACTS...SEVERAL DAYS OF DANGEROUSLY HIGH HEAT AND HUMIDITY...

WITH LITTLE RELIEF FROM THE HEAT AT NIGHT...CAN CREATE

SIGNIFICANT STRESS ON INDIVIDUALS...AND WILL INCREASE THE RISK

OF HEAT RELATED ILLNESSES SUCH AS HEAT EXHAUSTION AND HEAT

STROKE.

The more I look at this and back at things, this summer really is about huge amplitude across short spatial domains. We have -1SD along and just off the West Coast, and +3SD ridge in the heart land, and neutral negative SD locally that is apart of a stronger negative anomaly seemingly a permanent fixture NE of us. This static configuration is causing some pretty wierd gradients across the country. 110 in OK and 60 in ME

EXTENDED FORECAST DISCUSSION

NWS HYDROMETEOROLOGICAL PREDICTION CENTER CAMP SPRINGS MD

156 PM EDT THU JUL 14 2011

VALID 12Z SUN JUL 17 2011 - 12Z THU JUL 21 2011

...HEAT WAVE EXPECTED ACROSS THE CENTRAL PLAINS/MIDWEST/LOWER OHIO

VALLEY...

...HEAVY RAIN POSSIBLE ALONG THE SOUTHEAST COAST THIS WEEKEND INTO

EARLY NEXT WEEK...

MODELS ARE SHOWING A BIT OF SPREAD WITH THE TROUGH EXPECTED TO

REMAIN NEAR THE WEST COAST...AND A BIT OVER SERN CANADA AND THE

NORTHEAST U.S. AS THE 00Z UKMET/00Z ECMWF NOW MOVE TEH WRN TROF

BODILY OUT ACROSS CANADA...WHILE THE 00Z GFS KEEPS THE TROUGH IN

PLACE. BOTH THE 00Z GEFS AND 12Z ECMWF ENSEMBLE MEANS SHOW

RIDGING REMAINING ACROSS THE NORTHEAST PACIFIC...AND TROUGHING

REMAINING NEAR THE WEST COAST LIKE THE 00Z GFS ADVERTISES FROM

TUESDAY ONWARD. ANY DISTURBANCES MOVING OUT OF THE MEAN TROUGH

SHOULD MOVE OVER THE DOWNSTREAM RIDGE ACROSS CANADA WITHOUT

WEAKENING THE RIDGE SIGNIFICANTLY. THROUGH MONDAY...THE GUIDANCE

IS IN GOOD AGREEMENT. EXPECT THAT THE ERN CANADIAN TROF IS

OVERDONE BY ECMWF AS INDICATED BY ENS MEANS AND IS A TYPICAL ECMWF

BIAS. HAVE ADJUSTED FOR THESE DIFFERENCES USING A BLEND OF 00Z GFS

AND 00Z GFS AND ECMWF ENS MEANS.

Help me out here ... That same assumption was applied to today's trough translation and how well did that help? not much - came right on down this time. Guess that means that any ECM trough shouldn't be ignored. Or am I missing something -

that's amazing stuff - even more so is that ridge is such a permanent feature right now - that 7 day forecast is basically a slam dunk. funny to think they are issuing that for 6 days out!
