Oh What a May It Was

Hard to know how to present all the notable events of May 2013, so when in doubt, put up a chart. Here's a plot of the daily mean temperature at Fairbanks in May.

Only six seven days the entire month were within one standard deviation of normal. On to the highlights:
In the Weather Bureau/NWS era (starting 1930)

• 10th coldest May
• Latest date (May 18th) of record with a daily high temperature below 40ºF and daily mean  below freezing
• Three daily record low temperatures and two record low max temperatures
• Winter snowpack melt-out of May 11 is the second latest of record
• 18 days with daily low temperatures of  ≤32ºF is most in May since 1964
• Green-up of West Chena Ridge as seen from UAF on May 26th is latest since observations began in 1974 and probably latest since 1964
• The 47 consecutive days with daily mean temperature below normal appears to be a record for such a streak, though it is not a record for consecutive days with departure of the same sign (53 days in a row in autumn 2002 above normal)
• Lowest April-May of record (mean temperature 31.3ºF)
• Fourth lowest March-April-May of record (mean temperature 23.2ºF)

On the warm side:

• Daily record high of 84ºF tied on the 30th
• Five days with highs in the 80s ties for second greatest such days in May (record is seven days in 2011)
• First time ever in May with five straight days of highs 82ºF or higher (thanks to reader Brian for this one)
