The ridge of high pressure causing this week's record-setting heat wave continues to drift east today, and will inflict extreme June heat across most of the central U.S. and Midwest on Thursday. Triple-digit heat (and heat indices) will be widespread from the Midwest (Chicago, Detroit, Cleveland) to the Mississippi and Ohio River Valleys (St. Louis, Louisville, Memphis). Ann Arbor, Michigan has reached 100° as of 4pm EDT. Heat advisories spread from Kansas north to Michigan, and as far southeast as North and South Carolina.

On Wednesday, 16 all-time record highs were broken or tied from Wyoming to Kansas, and 47 month-of-June records were either broken or tied. 66 warm overnight low records were also tied, 8 of which were all-time records for the month of June. The temperature did not get below 81° in Lamar, Colorado Tuesday night. The overnight low temperature is an important barometer for public health and safety in extreme heat waves; if the mercury does not drop significantly, our bodies (the sick and elderly, in particular) cannot recuperate.


Figure 1. Heat advisories (pink) from Kansas north to Michigan, and as far southeast as North and South Carolina on Thursday, where heat indices are expected to reach 105, as much as 110 in some places.

Our Weather Historian, Christopher C. Burt, wraps up yesterday's significant temperature records:

• Lamar, Colorado hit 112°, which is the city's hottest ever reading, beating 111° measured a few days ago and also on July 13, 1934.

• Dodge City, Kansas finally broke free of its multiple 110° previous all-time records with 111° on Wednesday. Dodge City has one of longest periods of record in the United States, with temperature records beginning on September 15, 1874.

• Hill City, Kansas hit 115° as it did on Tuesday as well, again just 1° short of all-time Kansas STATE June record of 116° set at Hugoton on June 25, 1911.

• Tucumcari, New Mexico hit 108°, just 1° short of all-time record as was the case in Goodland, Kansas and many others.

Waldo Canyon Fire gains 5,000 acres, still 5% contained

18,500 acres (up from 13,5000 on Wednesday) have been consumed, and $3.2 million spent fighting, in the Waldo Canyon Fire which is burning northwest of Colorado Springs and encroaching on the city. The fire remains 5% contained. Around 32,000 people have been evacuated as of Thursday morning as fire fighters continue to battle the blaze, with some help from the weather. Colorado Springs is forecast to reach 97° on Thursday, though it will be slightly cooler in the hills where the majority of the fire is burning. The red flag warnings have been dropped as wind speeds calm to 5-10 mph out of the northwest. However, humidity will still be relatively low, around 15% at the peak heat of the day. Thunderstorms are in the forecast, which creates the threat of lightning-induced fires

In the Tropics…

An African easterly wave in the central main development region of the North Atlantic is still producing some disorganized thunderstorm activity. The circulation in the wave is moderate but somewhat displaced from the strongest thunderstorm activity, though given the moderate wind shear the wave is experiencing that's not surprising. Sea surface temperature is around average, 28° C (82° F), which is warm enough to support tropical development. The National Hurricane Center continues to give this wave a 10% chance of developing over the next 48 hours.

There are a couple more tropical waves expected to leave the coast of Africa in the next week or so, neither of which are showing any signs of development in the models.

I was wondering what I would find back here when the blog jumped from 2137 thru 2138 to 2139.
As it says on the first comment, there's a New Blog... and it ain't this one.


Yeah, I was wondering the same thing. I was on the blog that was up most of today, saw the notice and it took me here. Was curious why there were only 15-20 comments.
Thanks for posting the more current link, aspectre.

By the looks of the MJO forecast July seems inactive....Still think we'll see one storm.

884 MoeWest: Ok, ok, I admit it was drought induced wishful thinking. NEED rain here on Curacao.

Pret' much a permanent feature of the ABC Islands, ain't it? Near drought, nearly all the time? What I don't get is how you can be so close to Venezuela&Colombia, and not get soaked when they do.

I found this on Answers.com...it's talking about Aruba, but i think that it would be the same for the ABC islands
"Aruba's climate is moderated by the trade winds. The trades are the prevailing pattern of easterly surface winds found in the tropics. The trades that affect Aruba blow from the northeast. In moving across the Atlantic from the northwest African coast, these winds drop rain on the Windward Islands of the Lesser Antilles. By the time the trades reach Aruba they're holding a scant amount of rain."

Trip digits in SC IL, thankfully only 20% humidity today, sure that will change as high moves east and taps gulf, some clouds north hope they get some rain. 107 in StL, glad someone else took the tix for this weekend's series w/ Pirates, takes too many $9 beers to cool down in the bleachers. Long range has rain day 7-10, but believe it had that last week and none in sight, so prob stay dry, bad time for that as most corn in area is tasseling.

You know this water vapour soaked North Atlantic and continuing low latitude jet stream is making for a non-summer here in England. Debby's moisture will get here come Monday to add to the misery...
