00:39 First Warm-Blooded Fish Found Researchers say this odd-looking fish, called the "Opah" or moon-fish, is the first fully warm blooded fish ever found.

An unseasonably early heat wave kicked into high gear over the Pacific Northwest June 8, 2015, sending at least two cities to their highest temperature ever recorded in the month of June.

Yakima, Washington , topped out at 105 degrees June 8. That ties the city's all-time June heat record set June 23, 1992; importantly, it comes 15 days earlier on the calendar, making it by far the earliest 105-degree reading on record there.

The thermometer reached 100 degrees again on June 9 setting a new record and making it three days in a row for Yakima, which smashed the former record of 96 degrees (set in 1977) when the thermometer broke the century mark June 7 and hit 101.

Farther south, a high of 109 degrees set a new all-time June high temperature for Grants Pass, Oregon, on June 9. The previous record was 108 degrees on three occasions, most recently June 16, 1961. Records in Grants Pass go all the way back to 1893.

Besides the historic record high in Yakima June 8, other triple-digit highs in the region (based on preliminary data) included 105 in Hermiston, Oregon, and Pasco, Washington; 103 in Wenatchee, Washington; 102 in Ephrata and Walla Walla, Washington; 102 in The Dalles and Pendleton, Oregon ; 101 in Moses Lake, Washington; and 100 in Omak, Washington, a mere 40 miles south of the Canadian border. Lewiston, Idaho, also hit 100 degrees.

Gilroy, California topped out at 109 degrees June 8, their hottest day so early in the season. Their previous earliest 109-degree-plus day was June 15, 1961. This was also just 3 degrees shy of their all-time June high of 112 degrees, set on that same day in 1961.

Medford, Oregon reached 105 June 8, their second earliest date it has been so hot. Only June 6, 1926 (109) was hotter earlier on the calendar, according to Weather Underground's Christopher Burt .

According to preliminary data, two of the nation's hottest locations June 7 were in the Northwest. The mercury topped out at 106 degrees near Hermiston, Oregon, and at the Chief Joseph Dam in north-central Washington. Tacna, Arizona, was the only other spot in the nation to hit 106. By contrast, Death Valley in California only hit 105.

Missoula, Montana set a new daily record high on June 9 of 94 degrees. Boise, Idaho set a new daily record high of 99 degrees for June 9.

Seattle and Portland, Oregon also saw temperatures warmer than expected for this time of year. Highs in Seattle climbed into the 80s on again on June 9 and tied the record high of 87 degrees on June 8. Portland reached 90 on June 8 and the upper 80s June 9. The average high in Seattle for early June is in the upper 60s, and Portland usually sees highs in the lower 70s. This warm spell comes after the warmest winter on record in both Seattle and Portland.
