Potential record-breaking rainfall to the southern Prairies
Some cities in the southern Prairie provinces have the potential to break some rainfall records on Tuesday. We’re getting this massive surge of moisture coming all the way up from the Gulf of Mexico. Now normally you get your moisture from the Pacific, so this is bringing in quite a lot of warm and pretty Hardy moisture all the way up from the South. Now normally you’d see anywhere from about 40 to 50mm on average in May for regions in southern Alberta and southern Saskatchewan, but come Tuesday now it’s already underway Monday evening. It’s going to intensify on Tuesday afternoon for regions in. Like Medicine Hat in southeastern Alberta and southwestern Saskatchewan, Swift Current, even all the way over to regions like Regina, could see some pretty impressive rainfall totals, now upwards of 100mm of rain for this entire event. That’s throughout Wednesday for those SE and southwestern corners. As we head further up the QE 2 corridor all the way up to Edmonton, we could still see 30 to 50mm. And I did mention we could break some records. The rainiest mayday in Medicine Hat is only 40mm and we are forecasting 40 to 50.
