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.

...NEW RECORD LOW TEMPERATURE AT HUNTSVILLE...
NEW RECORD LOW TEMPERATURE OF 56 DEGREES WAS SET AT HUNTSVILLE. THIS BREAKS
THE OLD RECORD OF 60 BACK IN 1914.

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.

Is it a wording mistake by NWS or is it stuck on the words maximum, record high, extreme, and others to go along with blazing red color system bias?
Joe, a warm front can come through in the middle of the night, or a cold one in the middle of the daylight hours. Let’s say it gets as warm as 69F at 3 am, and then a cold front starts blowing through, so the temperature starts falling off from there. Maybe by 3 pm (midafternoon), between the cold front and the sunshine, it’s only 60F, and steadies there for a while, before cooling again as night falls.
The high temperature from midnight to midnight — i.e., the high temperature for the calendar date of this hypothetical “day” is 69F. Would you call that the “day-time” high? I wouldn’t. But it IS the maximum temperature for that calendar “day”.
Let’s further hypothesize that the date is July 30; that in this location, “July 30” over the last 100 years has had an average high temperature (regardless of time of day) of 75F; and that on, say, July 30, 1922, the maximum temperature reached was only 71F (and, sure, it was your “daytime” high). Let’s say that the maximum temperature for “July 30” in this place has never been that low since — until this year, when the, yes, “low maximum” was only 69F — it was the “maximum” for this day, but not during daylight hours, AND a record-breaking “low maximum”.
Get it?
Low maximum is fine. Your spelling of “non-sequiture” is not. Neither is your understanding of the meaning of that term. Ditto your assumption that “maximum temperature” and “daytime temperature” are the same thing.
Cool & wet here in Denver on the other side of the same cool push – raining & 56 at my location as I type this. Expected high only in the 60s, normal high of 89. Anecdotally, this has been the cloudiest summer I can remember here over the last 17 years at this location. Not necessarily the coolest, as we have had hot streaks, but frequently punctuated by cool, cloudy wet days like today.

Make a list of all the maximum temperatures for the date over the years where you have data. Pick the highest, that’s the record high maximum. Pick the lowest, that’s the record low maximum. They sometimes occur at midnight so referring to daytime temps won’t work. (Besides, the lowest DAY-TIME temperature typically occurs at dawn.)
Improvements are welcome, I’m sure.
Joe, if the highest temperature for July 30 is the “daily maximum”. and you looked at all the July 30 “daily maximums” in the record, what might you call the lowest value of that set?
FWIW, Atlanta and Macon also broke previous low temperature records for this date (July 30):
Atlanta: 60°F, breaking previous record of 61°F from 1936
Macon: 61°F, breaking previous record of 62°F from 1930

what is the point in linking all this stuff if you don’t explain what you “precursor” is and provide a data source?
Hi Greg
Thanks for the comment. Every now and than we look at climate models from academia and individual contributors, made out of multiplicity of the components, and hardly anyone knows what they are made of and even less how they work.
The link you quote, is not a model but a straight forward comparison of two well known variables (sub-equatorial N. Atlantic hurricane annual numbers and sub-polar N. Atlantic atmospheric pressure). Knowing that isn’t of any help since I do not think there is any single or collective assembly of ideas that may explain the processes involved if any, thus it belongs to the realm of speculation, as the most of predictions do. Here I was guided by a simple principle ‘if it worked during the most of the time the past, it just may work in the near future’, but the advice is:do not cancel your insurance policy.
previous comment re: record low temps in Atlanta & Macon was mine; I botched pasting my usual name.
Jealous of all you folks with lower than average temps. Not so here. It’s been in the upper 90s or low 100s all month. Not unusual for this time of year, but it would be nice to have some of those lower temps! Come to think of it, there were a couple days last week down into the upper 70s, and that was nice!
FWIW, both Atlanta and Macon (Georgia) set new record low temps for this date (July 30):
Article is here.
New Atlanta low is 60°F, breaking previous record of 61°F from 1936.
New Macon low is 61&def;F, breaking previous record of 62°F from 1920.
Hmmm … Two harsh winters followed by cool springs and summers. Could this be a climate shift back to the old normal? Can’t be, because CO2 continues to rise. >/sarc>

It has been unusually wet and cool here in NH this summer. Spring was also somewhat wet and cool, as I recall. But, that’s “Climate Change” for ya. Had it been unusually warm and dry, that would have been “Global Warming”.
The news this morning said about 2,000 people die each year in the US from the weather, most die from the winter cold. I’m having trouble tying this to climate change but I’m confident someone will think of a way.
Everyone needs to calm down a bit. This may be a record Low Maximum, or record High Minimum, Or a Record Global Warming Negative, or Climate Disruption anomaly, but actually after all of the data and homogenization are in, the temperature was shown as 57, but in reality it is only 56.6003472942567 F. Rounded up and therefore Global Warming is real, frightening and dangerous. Run for the hills!!!!

Accumulated cyclone energy, ACE, follows solar activity. Presently there is insufficient solar activity for hurricane development. Give it a chance, as the most active regions on the sun are now rolling into earth-facing position, SSN and solar flux are now up from very low levels that began almost two weeks ago. While the energy of the sun has waned with each solar rotation so far this summer, she may wax brilliant again long enough to warm tropical waters up enough to drive the high volume surface evaporation needed for cyclogenesis. She may also give us some flaring events that can rapidly energize the Earth’s electric field, which helps to provide the extra massive uplift and rotation needed for big cyclones/hurricanes vs regular tropical storms.
Since the sunspot number dropped to zero on July 17, the morning heat index temps across the US have fallen dramatically, and it’s generally cooled off everywhere except the coastal and SW states. It’s been cool in Michigan, barely getting to 60F every day, and gardeners and farmers all across the region are dealing with spindly plants and less fruit from not enough Sun! Our garden took off well when the Sun was more active earlier in May/June, but it’s struggling now.
The present cooldown in the US has reached the Gulf States. The cold front sitting across the south now is a repeat of the situation we saw several weeks ago under similar circumstances, and similar to last winter, when the “polar vortex” pushed cold air all the way into Florida.
The “super” moon’s effect on atmospheric tides is seen in weather map analysis, as it has pulled cooler air from the Canadian north southward, easily counteracting recently weak solar-driven tropical warmth, as it went from max declination north on July 23, to tomorrow at the equator headed southward, with still a week to go before it peaks south before heading back north, when it will drag warmer tropical air northward with it on it’s transit north, as it always does.
Today, the SSN is 160, and F10.7 is 132, from small, unimpressive sunspots, and in the next week, the mildly higher solar activity will provide some warm-up. See http://origin-www.swpc.noaa.gov/products/usaf-45-day-ap-and-f107cm-flux-forecast 45-DAY F10.7 CM FLUX FORECAST:

The Air Force also thinks the sun’s energy is slowly tapering off. I’m curious how agricultural output will turn out from the northern states and Canada after the season is over. Will food production be down from lack of solar intensity? Things are shaping up for a repeat and worse of last year’s severe US winter, as many long-range forecasters are saying. What say you Mr. V?
And humidity at 90 percent. What happened to those green house gas down-welling IR fluxes keeping us all warm?
How can someone that works for the National Weather Service be so stupid. A record high temperature of 81 degrees in Alabama during July, are you kidding? That doesn’t even make sense.
Runway or UHI doesn’t matter, under the local conditions “calm” means almost no wind a black body
can go lower than normal temperatures just before morning.

Wednesday July 23 was a day of new weather records across Oregon and SW Washington In one instance, Portland Airport broke the all-time rainfall record by a factor of ten! Other areas with longer records, like Vancouver, WA, broke rainfall records that have stood for almost a century. We alo had a number of record low high temperatures. Portland tied a record low high of 68 F set in 2008.

And the point is that these low temperatures somehow disprove AGW? While the eastern US has experienced cool temperatures this year, it is just about the only place on the planet that has:
http://www.ncdc.noaa.gov/sotc/service/global/map-percentile-mntp/201401-201406.gif
The point is that neither record highs OR record lows prove/disprove AGW. However, when an hundred year old high temp is broken we are inundated with foolish claims of “proof”. A record low will be all but ignored by the alarmists.
huntsville should have set a new record low for the 29th also since they went below 60 before midnight……usually the low temp comes around sunrise, but last night it was already below 60 before midnight which was colder than the sunrise temp earlier on the 29th..
105º in Omak, Washington yesterday, 40 miles south of here. More wild filers were started, no relief from emergent phenomena, deer are emerging from the surrounding hills seeking water and browse, my tomatoes went missing overnight. My coffee trees are carrying more cherries right now than at any time in the last 10 years. Some like it hot.
