SUBJECT: St. Cloud having a "cool," not a "rad" summer
         July 2000 St. Cloud weather summary
        The trend of cool summers continued in St. Cloud during
July 2000. The average temperature of 69.2 degrees was nearly 
a full degree below normal. As was the case in June, the month
began warm and humid, with 2 90+ degree highs by the 9th and frequent
outbreaks of thunderstorms. However, a major cool push moved in 
between the 17th and the 25th. This period included cloud cover due
to lingering thunderstorm moisture and a cool Canadian air mass.
The lingering clouds from morning thunderstorms on the 18th resulted
in record cold high temperatures across much of Minnesota, Iowa, and
Wisconsin. In St. Cloud, the high temperature of 57 on the 18th broke
the record cool high for the date by 10 degrees and tied the coolest
July high of all time (see below). Temperatures did rebound during the
last 4 days of the month, breaking 90 degrees for the third time during
the month. Still, for the most part, St. Cloud has been spared the searing
heat seen in the Southern Plains.
         As was the case in June, there were many rain events in July, but
few heavy ones. Despite having 13 days with measurable precipitation, St.
Cloud only received 3.25 inches of rain, only .14 inch above normal. The
near normal rainfall left St. Cloud still nearly 3 inches behind for the
growing season. In fact, the St. Cloud Airport is part of a small area
from eastern Stearns County through eastern Wright County and parts of
Sherburne and Anoka Counties which have only received 60-80% of the normal
growing season rainfall. Again, because of the cool conditions, the effects 
of the dry spell has been limited. Still, it has resulted in the uneven
crop development in much of central Minnesota.
          Now that two of the three summer months have had below normal
temperatures, it's time to remember that the decade of the 1990's (1991-
1999) has had the coldest average summer temperatures of any decade in
St. Cloud records. So far, the summer of 2000 appears to be along the same
