Depending on where you are in the province, last week’s forecast was either right on the money or off by a little bit. We saw the heat until Thursday as predicted, but over the weekend some regions saw nothing but rain and thunderstorms, while other regions saw only a little bit of rain and plenty of partly cloudy skies. By the start of the week the forecasted call for a cool, blustery day panned out, just a day earlier than expected.
For this forecast period it looks like the unsettled weather will continue. After the cool, wet start to the week, temperatures should warm back into the low 20s for highs by Wednesday, and these mild temperatures should last right through this forecast period. Low pressure will slowly build to our west during the week and this low will help pull up the mild air, but along with the warmer air will come increasing moisture and the chances for showers and thundershowers almost every day. By the weekend part of this western low looks like it begins to push east, bringing a bit more cloud along with more chances for showers or thunderstorms.
Next week looks like it will start off with an upper trough of low pressure sitting just to our west. This will keep temperatures fairly mild as we see a continued southerly flow along with a mix of sun and clouds. This western upper trough of low pressure looks like it will stay in place for much of next week, kicking out pieces of energy every couple of days. This will result in temperatures remaining in the low 20s for highs, with overnight lows in the low to mid-teens. It also means we’ll see partly cloudy skies on most days and will likely see the chance for the odd shower or thunderstorm just about every day.
Usual temperature range for this period: Highs, 19 to 29 C; lows, 7 to 16 C.
