7 PM MDT Update: A preliminary report from the National Weather Service confirms the Goodland record high of 110° at 2:53 pm, eclipsing the old daily record of 107° in 1971.

The 115° high temperature is a new all-time June record at Hill City, where records began in 1896; it smashes the old daily record of 110° in 1980.

Also in Kansas, Dodge City (110°) and Garden City (108°) tied records set just last year.

Russell, Kansas hit 112°, breaking the record of 108° in 1980.

Burlington, Colorado also crushed a record with 106°, exceeding the 102° in 1990.

The prize for excessive record margin goes to McCook, Nebraska, where the 115° high was 12° above the old record of 103° in 1998. McCook climate records began in 1896.

Steve, is this a blocking event? It seems somewhat persistent, and is there any connection to Debby's slow movement?

CapitalClimate said...

Yes, this is a classic summer blocking pattern, with a strong high pressure ridge over the central part of the US. The difference is that this is more intense than average, so extreme temperature records are being set.

Debby was trapped between this mid-latitude ridge and a subtropical ridge to the south. For a time, it appeared that the strength of the northern ridge would force Debby westward in the Gulf, but the westerly flow aloft (shear) weakened the storm, and it eventually worked its way eastward.
