Weather: Hot weather looks set to continue

Forecast covering the period from June 9 to June 16

This map shows the forecasted CFS weather model temperature anomaly for the three-month period of July, August and September. Nearly all of Canada is expected to see above-average temperatures, with only a few locations seeing near average. Across the Prairies, above-average temperatures are in the forecast, with the exception of southern Saskatchewan, forecasted to have near-average temperatures.

Well, the warm, dry weather won out in last forecast. All it took was a northward shift of a few hundred kilometres to go from highs in the upper 20s to highs in the low to mid-30s. The area of low pressure that was forecast to track through southern and central regions late last week did form, but tracked much farther north, thanks to a fairly strong ridge of high pressure. That ridge brought us our first real taste of summer heat.

For this forecast period, the weather models show an area of low pressure developing to our southwest. This will place us in a warm southerly flow ahead of the low, which should push daytime highs on Wednesday, June 9 into the low 30s. This area of low pressure is forecast to track through either southern Saskatchewan or southern Manitoba on Thursday. This will bring the chance of showers and thundershowers to southern and central regions, with some storms possibly becoming severe, depending on the exact timing of the system. This system should move off to the north and east by Friday.

Skies look to clear over the weekend with temperature remaining fairly mild. Expect daytime highs to be in the mid- to upper 20s with overnight lows falling to around 14 C. With summer heat and increased levels of humidity, do not be surprised by the occasional late-day thundershower.

The week of June 14 to 19 is looking very warm as the weather models show a building ridge of high pressure. This will bring mostly sunny skies along with daytime highs pushing back into the low 30s and overnight lows only dropping into the mid-teens, which are at or above the high end of the usual temperature range for this time of the year. Again, there will be the chance for thunderstorms on any given day with the heat and humidity.

Usual temperature range for this period: Highs, 19 to 28 C; lows, 6 to 15 C.
