SALT LAKE CITY — Last month in Salt Lake City was the third-coolest May on record and the coldest in 57 years.

"Very cool and wet" is the official description of last month from the Salt Lake office of the National Weather Service.

Only the months of May in 1933 (52.2 degree average) and 1953 (52.9 degrees) were cooler. May 1952 was just as cold as May 2010, with an average temperature of 53.2 degrees.

May temperatures were almost six degrees below normal, on average. There was just one 80 degree or above temperature the entire month, and that was on May 17, at 82 degrees.

The coldest recorded temperature for the month was the morning of May 7, at 31 degrees.

The month featured just two days with above-normal temperatures, two normal-temperature days and 27 days below normal.

May also boasted 2.8 inches of precipitation at the Salt Lake City International Airport, which was 134 percent of normal.

However, snowfall for the month was just 0.2 inches at the airport, or 29 percent of normal. And yet, that snowfall set an all-time record for the latest-ever season snowfall measured at the airport, on May 24. That shattered the previous record of 0.5 inches on May 18, 1977.

Despite only sparse snow at the airport, Alta received 41.5 inches of snow during May (6.43 inches of moisture), which was 151 percent of normal for the month.

Laketown and Randolph in Rich County received the most proportional moisture during May, with 219 percent and 188 percent of normal precipitation for the month, respectively.

Delta and Fillmore were also well above normal moisture, at 174 percent and 173 percent of normal for the month, respectively.

There were some drought areas of Utah during May, too. For example, Kanab received just 0.5 inch of precipitation during the month, or only 7 percent of normal. Alton, Kane County, was even worse, bone dry at 4 percent of normal, and the Cedar City Airport had just 15 percent of normal moisture during May.

June thus far has been the opposite of May, with just one day — June 1 — with below-normal temperatures. The rest have been well above the norm.

For moisture during June, the Salt Lake airport was at zero for the month through midday Monday. However, the National Weather Service is forecasting at least a slight chance of showers or thunderstorms each day this week — through Sunday — mainly in the afternoon.

After a high near 78 degrees Tuesday, the mercury will soar to 88 degrees Wednesday, under partly cloudy skies.

Daytime temperatures are predicted to drop to the mid-70s by Thursday and then drop further to the upper 60s, where they will remain through Sunday.
