Forecast: Warm weather looks to continue

Issued July 9, 2018: Covering the period from July 11 to 18

This map shows the per cent of average precipitation that has fallen across the Prairies so far this growing season. Over the first three months of the growing season, most regions received below-average amounts of precipitation. The northern Prairies, along with eastern Saskatchewan and far western Manitoba, have seen above-average amounts.

This forecast period looks like it will be a repeat of last week’s weather. Last week began with an area of low pressure bringing clouds along with showers and thundershowers. This was then followed by a return to sunshine and warming temperatures that culminated in the really hot and humid weather we experienced last Saturday. We didn’t see the big outbreak of severe weather on Saturday night or Sunday morning, but a few areas did see some light showers. We then started off the week with a return to sunny skies and warm temperatures.

For this forecast period we will start off once again with an area of low pressure tracking from Montana into north-central Manitoba. This will place most of the forecast region on the southern side of the low. We should see a mix of sun and clouds on Wednesday along with the chance of showers and thunderstorms, especially late in the afternoon. Temperatures will also be warm, with highs expected to be in the upper 20s to low 30s, depending on just how much sunshine there is.

Thursday and Friday look to be quiet, with plenty of sunshine and warm temperatures. Attention then turns to an area of low pressure forecast to develop to our southwest on Friday and then lift northeastward on Saturday. Current weather models show a very good chance of seeing some strong thunderstorms with this system late on Saturday or early Sunday. It looks like skies will be slow to clear on Sunday as the low slowly moves off into northwestern Ontario. Western regions should clear by Sunday afternoon, with eastern regions not seeing clearing skies until late in the day. Temperatures will be warm ahead of the low on Saturday, but will cool down on Sunday, with highs expected to be in the low to mid-20s.

The first half of next week looks to be nice as weak high pressure builds back in. Expect plenty of sunshine with daytime highs in the 24 to 27 C range and overnight lows in the 12 to 15 C range.

Usual temperature range for this period: Highs, 22 to 31 C; lows, 10 to 17 C.
