Actually, two new records; one for high one for low. This from earlier:
RECORD EVENT REPORT
NATIONAL WEATHER SERVICE HUNTSVILLE AL
132 AM CDT WED JUL 30 2014
...RECORD HIGH MAXIMUM TEMPERATURE TIED AT HUNTSVILLE...
A RECORD HIGH MAXIMUM TEMPERATURE OF 81 DEGREES WAS TIED AT
HUNTSVILLE ON TUESDAY (7-29-14). THIS TIES THE OLD RECORD OF 81 SET
IN 2006.
Actually, they have the wording backwards, it is supposed to be record low maximum. Obviously 81 degrees is not that warm for July in Alabama. They’ll probably issue a correction later. The NWS predicted the new record low earlier with this graphic:
Now the record has been broken according to the latest data from KHSV:
The temperature at Huntsville International Airport dropped to 57 degrees as of 4:53 a.m. 56 degrees.
The previous record for the date was 60 degrees set back in 1914.
UPDATE: 8AM PDT
The record DID go lower, to 56F, and I’ve updated the post.

Dr. John Christy writes in with:
A bigger story is the Montgomery low of 59F – tying the all time monthly record low for July set on 20 July 2009 from records that go back to the 1880s.

Black Locusts are happy, they often shed their leaves early during dry summers.

Prb’ly not dryness — here they turn brown mid-summer from plagues of the Locust Leaf Miner.

On the NOAA medium and long range forecasts that blue blob keeps getting a little closer to Sunspot, New Mexico. Maybe if Alamogordo area breaks 100 year records Leif will notice????
dp and Ric, I also remember Omak but not fondly. 38 years ago my ex and I were on our way to visit Colville relatives who couldn’t come to our wedding. I got food poisoning in Omak from a tavern. The French dip “dip” did me in. I fainting off the notell motel toilet seat and hit the edge of the toilet paper roll holder. It was just great showing up as a newly wed couple with a black eye.

Thanks ren, yes, there’s the source of the higher temp variability.
The mid-level to upper blocked pressure pattern seemed even more distinct last week. The current cold pulse low is present from surface to 250 HPa.
Looking at the Jetstream for tomorrow over the same area I don’t know if I’ve seen it so strong over such a wide band of latitude, but then goes into these NS standing-waves. Fortunately one of them has not shoved polar air right into the eastern tropics for a week or two … yet.
Sorry for got the link:

Sub-tropical and polar jets combine then polar jet detaches into tight NS oriented standing waves. Not unusual but subjectively it all looks more energetic than usual.
Lower highs and higher lows; which will win?
