Las Vegas officially tops century mark for first time in 2013

The first official 100-degree reading of the year is in the books in Las Vegas.

The National Weather Service’s official recording station at McCarran International Airport showed a reading of 100 degrees at 11:36 a.m., according to a posting on its Facebook page.

Before Monday, the last time Las Vegas officially hit 100 degrees was Sept. 9, 2012.

The average high temperature for Monday's date at McCarran is 88 degrees. But a 100-degree reading is not that out of the ordinary for this time of year. Last year, Las Vegas got its first triple-digit temperature day on May 16. The earliest date the valley has officially recorded triple-digit figures was May 1, 1947. The latest was on June 30, 1965. The average date is May 26.

Readings of 100 are forecast again Tuesday, but a slight cooling trend is expected later in the week. The forecast high Wednesday and Thursday is in the mid-90s, before high temperatures drop to around 90 on Friday.
