This spring will be cooler in many regions as La Nina continues throughout the region, but others will experience warmer than normal conditions. I have outlined the specific areas below.
I do believe that, as spring wears on, people in Southern Canada will experience warmer than normal conditions, as well as infrequent heat waves, pushing temperatures as high as the low 70's in places.
There is forecast concern of the area by Alaska, where temperatures may actually be more warm than cooler, but I do predict that at least some of the area outlined in cooler conditions will get overall cooler conditions.
Precipitation-Wise, I believe storms will continue to affect the area, pushing the precipitation above normal in many areas.
However, the southern Canada areas mentioned in the heavy snowfall for this winter was due to a pattern in the US. That pattern is predicted to break down. Due to that, the precipitation outlook may look odd to people in Southern Canada. See the image below.
A strong low pressure system will move through the Midwest and produce a mainly rain event across the area. Below is an idea of the Canadian GEM model of how much precipitation in a 48 hour period could be expected in rain form.
This is an image of the 0z GEM Canadian model run. That blue line is the Rain/Snow live. When there is a certain area, from the rain/snow line to Chicago in this case, wintry precipitation is likely to be mixed with rain. This could create hazardous conditions and flooding, and this situation will have to be monitored.
