Showers & Thunderstorms - warmer next week for Montreal

Yesterday was the fourth day in a glorious stretch of sunny and warm weather for Montreal. We managed 24C (76F) on Wednesday and we should get close to that as well today. An upper level disturbance in the atmosphere will slide across eastern Ontario and into New York state over the next 24 hours introducing clouds and showers to southern Quebec. The bulk of the activity today will be over Ontario but will expand into Montreal later this afternoon. It will not be a washout by any means but showers are possible right into Saturday. Skies will partially clear by Sunday and we can expect much warmer weather as we head into the last week of May, likely exceeding 27C (80F) next week.

Severe thunderstorms in the metro Denver area late Wednesday produced several inches of hail in some locations.

The warm air today will be across Saskatchewan and portions of southern Alberta where highs will reach 30C (86F). Yesterday very strong thunderstorms were reported across the southern Rockies northeast into the Great Lakes. A strong storm near Denver produced a tornado as well as several inches of hail. More storms will fire up today from Iowa towards the east coast as well as in southern Ontario.
