Weather: Below average to start, then warmer?

Forecast covering the period from June 2 to June 9

This map shows the total amount of precipitation that fell during the seven days ending May 26. This map captures the moisture that fell during this unsettled period and shows significant precipitation falling across nearly all of agricultural Manitoba and Saskatchewan, along with southern and central Alberta. While not a total drought-buster event, it was a good start.

It continues to be a tough time for the medium-range forecasts. The weather pattern continues to oscillate between cool and unsettled and warm and dry as summer tries to gain traction. Last issue’s forecast did pretty well but missed just how cold it got last Thursday and Friday mornings. I also hedged my bets on cool weather for the end of May and the start of June, but it looks like the warm weather ended up winning out.

For this forecast period it looks as though we will be in a predominantly westerly flow as an area of low pressure tracks across the northern Prairies. This will bring mainly sunny skies along with warm temperatures. Expect daytime highs to be in the mid-20s with overnight lows falling to around 10 C. By Friday, June 4, a trough of low pressure connected to the northern low will move through southern and central regions. This trough will likely bring clouds along with the chance of thundershowers and possibly thunderstorms, depending on the timing of the system.

It looks like we will get a short reprieve from the clouds and showers on Saturday before another area of low pressure tracks from Alberta into northwestern Ontario on Sunday. Southern and central regions are likely to see a few quick showers from this system before it moves off to the east on Monday, but with the speed of the system it does not look like precipitation amounts will be very high. Expect a bit of a cool-down behind this system, with daytime highs falling into the upper teens to around the 20 C mark by Monday, June 7.

Cool and unsettled weather looks as if it might stick around for most of the week of June 7 to 11 before temperatures warm as a trough of low pressure begins to develop to our southwest. Temperatures are forecast to be in the mid- to upper 20s by late in the week with overnight lows falling to around 12 C.

Usual temperature range for this period: Highs, 17 to 28 C; lows, 4 to 14 C.
