The main story of April 2007 was the dryness.. with only about 15 mm of precipitation for the month, or about half of the long term April average of 32 mm. The bulk of that precipitation was recorded on the first of the month when 10-12 mm of rain and wet snow was recorded in Winnipeg (Note: YWG airport’s reading of 24 mm for April 1st overestimated the actual amount by 2 times due to a recording problem) The rest of the month was dry, with only 3 or 4 minor rainfalls totaling about 5 mm. The dryness was a growing concern for area farmers coming off a record dry growing season in 2006 that has led to very dry soil conditions to start the 2007 growing season. The dryness contributed to an increasing occurrence of grass fires in and around Winnipeg, with a significant forest fire developing by the end of the month over southeast MB near Piney. Temperature wise, the month finished near normal.. however the month was split between a colder than normal first half followed by warmer than normal second half. In fact, the last two weeks of the month featured very mild temperatures with several 20 plus degree days.. including the month’s warmest reading of 26.7C on the 28th at Winnipeg airport.. the warmest April day in Winnipeg since April 29 2001 (28.3C) All in all.. a dry month with a warm finish.
