SUBJECT: Whatever happened to global warming? July 1998 St. Cloud weather summary The statistics for St. Cloud during July 1998 indicated a near normal weather month for the first time in quite a while. However, this was a result of a hot, humid, wet first two-thirds of the month balancing a relatively dry and cooler final third. During the first 20 days of the month, Minnesota was on the edge, if not within, the blustering air mass which has caused so much misery this summer in the Southern Plains. The average high temperature for July 1-20 was 83.1 while the average low was 60.5, inclduing the first two 90+ degree days in St. Cloud since May (13th and 14th). Also, the high humidity in this air produced 3.18 inches of rain during the first 20 days, including four days with rainfall of over 0.30 inch (.32 on the 2nd, .54 on the 5th, 1.62 in on the 14th, and .37 on the 18th). The heavy rain on the 14th was a small taste of the 6-8 inch rains experienced in the Fergus Falls area before the storm moved towards St. Cloud. And, St. Cloud missed the activity on the 20th, which included 100+ MPH winds in St. Peter and at least 6 tornadoes in northwestern and north central Minnesota. After that, the upper level flow turned to northwesterly and cooler and drier air moved in for the balance of the month. The temperature never rose higher than 84 during this period (avg high: 79.3; avg low: 53.6) and it was dry enough to actually cause some concern to lawn owners and gardeners (precip: 0.21 in). Some of the concern about the recent dry weather should be eased by the wet weather pattern during the first half of this week.
