Temperatures are set to rise as a wavy pattern develops over Canada for the final days of May<\/p>\n

A heat wave<\/a> is in the cards for parts of Canada heading into the final days of May as a blocking pattern sets up high above the country.<\/p>\n

This spell of heat will see daytime temperatures rise into the 30s alongside sticky humidex values.<\/p>\n

The short-lived pattern expected to build over Canada next week is known as an omega block<\/a>, named for its striking resemblance to the Greek letter omega.<\/p>\n

\"Caanda<\/p>\n

An omega block occurs in the upper levels of the atmosphere when a ridge of high pressure gets bookended by two troughs. Similar to a kink in a garden hose, this wavy pattern can be tough to dislodge and linger for days as a result.<\/p>\n

Above-seasonal temperatures are common beneath strong ridges of high pressure<\/a>, and we\u2019re set to see readings soar across the eastern Prairies during the latter half of next week.<\/p>\n

The warmest temperature recorded in Canada so far in 2026 was a 33.5\u00b0C reading<\/a> in Lytton, B.C., back on May 5. That national milestone could be in jeopardy during this upcoming heat wave, most likely in southern Saskatchewan.<\/p>\n","protected":false},"excerpt":{"rendered":"Published on May. 23, 2026, 12:38 AM Temperatures are set to rise as a wavy pattern develops over…\n","protected":false},"author":2,"featured_media":688173,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[4],"tags":[49,48,3609,16581,56323,44,11423],"class_list":["post-688172","post","type-post","status-publish","format-standard","has-post-thumbnail","category-canada","tag-ca","tag-canada","tag-heat","tag-heat-wave","tag-jet-stream","tag-news","tag-prairies"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/posts\/688172","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/comments?post=688172"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/posts\/688172\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/media\/688173"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/media?parent=688172"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/categories?post=688172"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/tags?post=688172"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
