Warm and active are the best ways to describe this forecast period. It finally looks as though spring is taking hold across the forecast region as fairly mild air moves in. Along with the warmer air will come plenty of chances for showers and thundershowers. Unfortunately, it now looks as though the warm air might not be here for good, as medium-range models show more cool air moving in next week.
After a windy start to the week we should see weak high pressure move in on Thursday and Friday. This should bring mainly sunny skies with high temperatures in the low to mid-20s. The weather models then show a large area of low pressure moving in off the Pacific and slowly making its way across the northern states over the weekend. This will bring increasing clouds, along with a good chance of showers and thundershowers beginning late on Friday and lasting right through the weekend. It now looks like most of the moisture will stay south of the border with this system. Temperatures will depend on the amount of cloud we see over the weekend. If we see more sun than clouds, highs should once again be in the low to mid-20s; otherwise, expect highs to be in the upper teens to around 20 C.
By early next week the weather models have this low deepening as it moves into the Great Lakes region. This will help to pull down plenty of cool arctic air behind the system, dropping our high temperatures down to around the 10 C mark. Overnight lows will also be cold and a few frosty nights cannot be ruled out. The models show the cool air sticking around for most of next week. I sure hope the weather models have it wrong this time!
Usual temperature range for this period: Highs, 13 to 26 C; lows, 1 to 10 C.
