It was another day of triple-digit heat across the Midwest Thursday, as the nation continued to bake in the intense heat of the record-breaking summer of 2012. Chicago hit 103° on Thursday, just 2° below the city's all-time hottest temperature of 105°, set on July 24, 1934. The Windy City might have exceeded their all-time heat record, but for the fortuitous formation of a small but intense thunderstorm that hit the airport at 2:45 pm. The storm brought a wind gust of 52 mph to the airport and cooled the temperature by 20°. A wind gust of 92 mph was recorded 4 miles offshore over Lake Michigan. Thursday was the hottest day in Chicago since a 104° reading on July 13, 1995. Milwaukee, WI also hit 103° Thursday, which tied for the 3rd hottest temperature in city history. Madison's 104° was their hottest day since 1988, and also tied for the 3rd warmest temperature ever measured in the city. Madison's all-time high is 107°, set July 14, 1936. St. Louis hit 105°, the eighth consecutive day the city has hit triple digits. This streak is now the 3rd longest such streak in city history; the only longer streaks occurred during the Dust Bowl summer of 1936 (streaks of 13 and 9 days.) The current forecast for St. Louis calls for highs of 107 - 108° Friday and Saturday, which will likely bring the city's streak of 100°+ days to ten by week's end. St. Louis' all-time hottest temperature is 115°, set in 1954.


Figure 1. The severe weather map for Friday, July 6, 2012, showed that advisories for extreme heat (pink colors) were posted for portions of 25 states.

The forecast: record heat Friday and Saturday, then relief
More record-breaking triple-digit heat is expected Friday and Saturday across much of the Midwest and Tennessee Valley, but a cold front will move southwards out of Canada on Saturday and Sunday, putting an end to this phase of the great heat wave of 2012. By early next week, temperatures will be near average for most of the eastern 2/3 of the U.S.

Quiet in the Atlantic
There are no threat areas to discuss in the Atlantic, and none of the reliable computer models are developing a tropical cyclone over the next seven days.

Derived from the 6July6pmGMT (NHC) ATCF data for TropicalStormDaniel:
14.5n113.5w - 14.7n114.4w has been re-evaluated&altered*
14.4n113.5w - 14.4n114.5w - 14.4n115.5w are now the most recent positions

Its vector* had held steady at 11.2mph(18km/h) West
MaxSusWinds had increased from 55knots(63mph)102km/h to 60knots(69mph)111km/h
And minimum pressure decreased from 995millibars to 993millibars

For those who like to visually track TS.Daniel's path...
HI25 is Naalehu :: SAN is SanDiego :: CSL is CaboSanLucas

Easternmost half-dot on the connected line-segments is where TD.4E became TS.Daniel
The Easternmost dot on the longest line is TS.Daniel's most recent position

The longest line is a straightline projection through TS.Daniel's 2 most recent positions to its closest approach to Hawaii
6July12amGMT: TS.Daniel was headed toward passing 196miles(316kilometres) South of Hawaii
(Northern dot on the unconnected dumbbell)
6July6amGMT: TS.Daniel was headed toward passing 268miles(431kilometres) South of Hawaii*

The previous mapping for comparison

The previous vector and the 2 previous straightline projections' endpoints have been corrected on this mapping through recalculations using the most recent positions.

no its not. It just means that 98F air has 99% of the moisture it can hold.
I dont know exactly where it happens, maybe just after a tstorm in 110 weather next to the ocean.


it doesnt happen anywhere lol...a 98 degree temp with 99% humidity produces a heat index of 179 degrees! where on earth have you heard of a heat index of 179? tell me and then ill agree with you!

A buoy 30 nautical miles northwest of Cleveland showing a water temperature of 84F this afternoon. Maybe we'll have tropical storms developing off the Great Lakes if this keeps up.

I just remembered the funniest mis-heard lyric ever. My daugter's friend used to replace a word in the Eagles song- "looking for a lover who won't blow my cover" with... well, replace "cover" with "a male sibling", if you wish to avoid a ban. Too cute!

Quoting BahaHurican:
I've been through a couple of these [though, God has been good, not a direct strike here by a Cat 5] so when I tell u I am getting a pretty good idea of how bad it was, I really mean it. That "splintered" look with the smaller limbs and trees - saw that all over the place after Floyd and Frances... We have quite a few fruit trees, and the downed and shredded look is quite familiar...

Aside from the loss of trees and other stuff, just the cleanup is - not so fun.
Other thing is, I passed through NE FL into the Orlando area 1 or maybe 2 days after Charley hit - on the 7th or 8th? We drove into Orlando after 11 p.m. in the pitch dark - all the power was out - and even in the dark we could see the skeletons of the delimbed and denuded trees. That was one of the most surreal experiences of my life.

Quoting Levi32:


Speed shear is simply shear induced by the difference in wind speeds between different levels of the atmosphere, not difference in direction of wind flow. Yes the term could be applied everywhere to an extent, but it usually refers to a uniform wind flow, such as off western Africa where both low-level and upper-level winds are easterly, but one air stream is faster than the other.
Thanks for clearing that up.

See, I told you if we glared at the GOM for long enough something would step up and manifest. I still don't know why some theoretical storms get diamond shapes instead of ovoids or spheres?
