Cumulative rainfall for the past 7 days was variable (Table 1; Fig. 3). Lethbridge reported 23.3 mm and 7.7 mm was recorded at Swift Current (Table 1). Cumulative 30-day rainfall was greatest across central regions of Alberta (Table 2; Fig. 4).  Rainfall amounts were lower across the southern prairies (Fig. 4). Total 30-day rainfall at Winnipeg, Brandon, Regina and Swift Current has been less than 65 mm (Table 2; Fig. 4).  Rainfall amounts have been greater across central regions of Alberta and Saskatchewan (Fig. 4).  Saskatoon has reported 131.9 mm (279% of normal) in the past 30 days (Fig. 5).  Growing season rainfall (percent of average) is below normal southern Saskatchewan and most of Manitoba (Fig. 5; Table 3).  Rainfall amounts are above average across central regions of Saskatchewan and across Alberta (Fig. 5; Table 3).

Weather synopsis

Weather synopsis –  This week, June 1-7, 2020, temperature and moisture conditions varied significantly across the prairies (Table 1; Fig. 1). Compared to Alberta, average 7-day temperatures were much warmer in Manitoba (Fig. 1). Average 30-day (May 2-31, 2020)  temperatures were warmest across central and southern regions of all three provinces (Table 2; Fig. 2). Temperature anomalies indicated that most of the prairies have experienced temperatures that have been up to 2 °C cooler than normal (May 1-31, 2020).

This past week, rainfall amounts were well above average across central Alberta; most of the prairies had minimal rain (Table 1; Fig. 3).  Eastern Saskatchewan and Manitoba have had the lowest 30 day cumulative rainfall amounts; precipitation has been greatest in Alberta so far this growing season (Table 2; Fig. 4). The recent rain has resulted in above normal rainfall (compared to long term normal) for most of Alberta (Fig. 5). Conditions continue to be dryer than normal across most of Saskatchewan and Manitoba (Fig. 5). Similar to last week, prairie rainfall amounts for the past 30 days have been approximately 125 % of normal.
