This map shows the total amount of precipitation that fell across the Prairies during the agricultural year ending Aug. 31. The eastern half of agricultural Manitoba saw the greatest amount of precipitation, with amounts in the 500- to 700-mm range. Precipitation amounts dropped off a bit to the west, with most of western Manitoba and eastern and central Saskatchewan seeing 350 to 500 mm. The driest region was west- central Alberta, where amounts were in the 200- to 350-mm range.

The mild September weather continued with last week’s forecast coming in pretty darned close to bang-on. For those of you hoping for dry, mild weather to continue, it looks like you’ll be in luck!

It looks more and more like the current weather pattern will continue at least into early October, with the main storm track staying to our north and a secondary storm track staying to our south. For the first part of this forecast, high pressure is going to slide by to our northeast, bringing plenty of sunshine along with daytime highs in the upper teens to around 20 C. This high looks like it should keep an area of low pressure well to our south on Thursday, although some clouds might work into extreme southern regions, with maybe a shower over eastern areas.

The models are then forecasting another strong area of low pressure to develop to our northwest and track through the southern territories. This will help to develop a fairly strong southerly flow late in the week and into the early part of the weekend, which should push daytime highs back into the low to mid-20s. We might see some clouds along with the odd shower on Sunday as a cold front pushes through, along with a weak area of low pressure tracking through North Dakota.

Next week’s forecast is a little uncertain as the weather models are developing a fairly large area of low pressure over the central U.S. on Monday, then tracking to the east-northeast on Tuesday and Wednesday. At the same time, high pressure will be building in from the northwest. Currently it looks like most of the precipitation from this system will be kept to our south, but the system does bear watching. The best chance for any rainfall from this system looks to be late Monday and into Tuesday morning over extreme southern and eastern regions.

Usual temperature range for this period: Highs, 9 to 21 C; lows, -2 to 7 C.
