During the last week or so we definitely saw and felt the cool arctic high pressure build in, bringing fairly cool conditions. Unfortunately for southern regions the area of high pressure was not strong enough to keep all the moisture from last weekend’s storm system to our south, with a good chunk of this region seeing between five and 10 centimetres of snow.
The overall pattern still does not look like it will change much over the next week or so. We are moving toward summer and the sun is getting stronger each day so we will be trending towards warmer temperatures, but it doesn’t look like we will break the 20 C mark during this forecast period.
The forecast period starts off with weak high pressure in place. This should bring us more sun than clouds and slowly warming temperatures. Highs by Friday will hopefully be pushing the 10 C mark. I am hoping this area of high pressure will keep a rather strong storm system well to our south. So far all the models show this but the models have been having a hard time of it this spring.
Over the weekend and into the first part of next week, we will see the region of high pressure slide off to the east. Out west, low pressure will be developing and these two features should combine to bring us a nice, mild southerly flow. If we can get enough sun, high temperatures on Sunday and Monday may make it into the mid-teens. By Tuesday the western low will be pushing through, bringing with it clouds and showers. We will then see a slight cool-down behind this low before temperatures start to warm up.
If we look a little further ahead, the models hint at some nice, mild temperatures to end the month, with highs possibly making it into the low 20s on the last day of April.
