TEMPERATURE: This past week (June 13-19, 2022) the average daily temperature (prairies) was 1 °C warmer than the previous week and 1.5 °C warmer than normal (Fig. 1). Though the prairie-wide average 30-day temperature (May 21 – June 19, 2022) was similar to long-term average values, the average 30-day temperature for May 21 to June 19 was 1.5 °C warmer than the average 30-day temperature for May 14 to June 12 (Fig. 2).
The growing season (April 1 – June 19, 2022) temperature for the prairies has been 1 °C cooler than climate normal values. The growing season has been warmest across western Saskatchewan and the southern and central regions of Alberta (Fig. 3; Table 1).
PRECIPITATION: Weekly (June 13-19) rainfall varied across the prairies. Significant rainfall was reported across Alberta (Fig. 4). Rainfall amounts were generally less than 10 mm for most of Saskatchewan. 30-day accumulation amounts have been well above average across large areas of Manitoba and Alberta while rainfall accumulation has been well below normal across Saskatchewan (Fig. 5).
Growing season rainfall for April 1 to June 19, 2022, continues to be greatest across Manitoba and southeastern Saskatchewan; rain amounts have been below normal across central Saskatchewan and near normal for Alberta (Fig. 6; Table 1).
Growing degree day (GDD) maps for Base 5 ºC and Base 10 ºC (April 1-June 20, 2022) can be viewed by clicking the hyperlinks. Over the past 7 days (June 14-20, 2022), the lowest temperatures recorded across the Canadian prairies ranged from < -2 to >10 °C while the highest temperatures observed ranged from <21 to >36 °C. Again this week, areas of the prairies hit warmer temperatures with a slight bump in the number of sites experiencing days at or above 25 °C across the prairies but little increase in the sites recording days at or above 30 °C.
