Seattle, Washington broke its all time high Record Temperature on July 29th of this Year.
From The Associate Press: Seattle breaks temp record as heat wave continues
By PHUONG LE and RYAN KOST (AP) – Jul 29, 2009
SEATTLE — Northwesterners more accustomed to rain and cooler climate sought refuge from a heat wave Wednesday, as Seattle recorded the hottest temperature in its history and Portland fell just 1 degree short of its own record-breaker.
The National Weather Service in Seattle recorded 103 degrees at Seattle-Tacoma International Airport, breaking a previous record of 100 degrees, set in downtown Seattle in 1941 and repeated at the airport in 1994.
Jay Albrecht, a Seattle meteorologist with the service, said it's the hottest it has been in Seattle since records dating to 1891.
In Oregon, heat records were set in cities across the western half of the state, with Portland topping out at 106 degrees, breaking the old record of 100 for the day but falling 1 degree shy of its all-time record of 107. Portland most recently hit the 107 mark in 1981.
Oregon weather data goes back to the 1850s, although meteorologist Charles Dalton said the 107-degree mark, recorded at the Portland airport, reflects records kept at that site since 1941.
Meteorologist Doug McDonnal in Seattle said the stretch of hot weather has lasted longer than usual. Wednesday was the fifth consecutive day above 85 degrees for Seattle, he said.
Throughout the region, shade, icy treats, ice-cold water, air conditioning units and fans were in high demand.

From the East Valley Tribune: July hottest month ever in Valley
Mike Branom, Tribune
July 30, 2009 - 3:49 PM
July 2009 will be the Valley's all-time hottest month.
Think about that: For all the baking summers since the start of weather record-keeping here more than 110 years ago, the thermometer's mercury has never risen higher than during these 31 days.
The raw numbers are staggering: Nine nights when the temperature didn't fall below 90 degrees; 15 days with highs at 110 and hotter. And almost no rain (0.40 inches - less than half of normal) to cool things down.

Updated: 11:30 AM August 1, 2009
With July 2009 now over it will go down as not only the hottest July on record but the hottest month of all-time in both Phoenix and Yuma (as determined by average temperature, see tables below). The data below represent the top ten warmest Julys for Phoenix and Yuma by average high, mean, and low temperatures. Records for Phoenix began in 1896 and for Yuma in 1878.
...
Why was July 2009 so hot? Figure 1 shows what the average weather pattern was in the mid-levels of the atmosphere, near 20,000 feet, during most of the month. As is often the case, there was a large ridge (Monsoon High) over the southwest states. More unusual was a persistent trough over eastern Canada extending into the eastern U.S. When looking at how this pattern differed from the long-term means (Figure 2), it can be readily seen that the atmosphere was slightly warmer than normal over the western parts of the U.S. and Canada while it was much cooler over the eastern U.S., centered over the Great Lakes region. Looking at the air temperature at about 5,000 feet above the surface, this pattern clearly showed up of cool in the east and warm in the west. In fact, while Phoenix and Yuma experienced the warmest July on record, locations such as Detroit, MI, Chicago, IL, Indianapolis, IN, and Marquette, MI had one of the coolest Julys on record.

Another factor in the record heat locally was the role moisture plays in observed temperatures. First, due to the physical properties of water vapor, it requires more of the sun's energy to warm a piece of "wet" air versus "dry" air by the same amount. Likewise, "wet" air can retain heat longer than "dry" air. Figure 4 shows that the amount of moisture in the air was above normal this month, which helped keep low temperatures well above normal. The high low temperatures create a positive feedback loop in that it is easier to have warmer max temperatures when starting from an already warm point in the morning. This helps negate the fact that "wet" air is slower to warm than "dry" air. This was more of a factor in the Yuma area. In Phoenix, a significant attributing factor was the urban heat island influence, which has been contributing to increasingly warmer overnight temperatures for several decades (Figure 5).
