Heat wave flows across southern Prairies

After much of the southern Prairies received varied amounts of rainfall, the clouds cleared for the sun to do its part on July 21– and in a big way. Southern Alberta near Brooks, Medicine Hat and Lethbridge recorded a temperature of 30 C with Weyburn and Estevan in Saskatchewan recording temperatures as high as 31 C. After southern Manitoba’s recent storm-related rainfall on July 20, temperatures ranging between 28 and 30 C were appreciated to help deal with excessive moisture.

Accumulated CHUs as of July 21 across the Prairie provinces (see map) vary widely from province to province with Alberta seeing a range of 1090 to 1360, Saskatchewan ranging from 1360 to 1495, and Manitoba ranging from 1410 to 1680.
