Forecast: A few more days of gloomy weather

Issued October 8, 2018: Covering the period from October 10 to October 17

This map shows the total amount of precipitation that has fallen across the Prairies during the 30 days ending Oct. 3. There has been significant precipitation across most regions, with amounts ranging from 25 to over 100 mm. The highest totals are found across Manitoba, with western regions seeing between 50 and 75 mm and eastern and central regions reporting widespread amounts up to and exceeding 100 mm.

This time all of the ingredients for the first measurable snowfall of the season came together, bringing anywhere from a light accumulation of snow to upward of five to eight cm. It then looked like we were going to see a major rain or snow event late last weekend and into the first half of this week. Fortunately, this storm system tracked farther east than originally forecast, which kept most of the precipitation to our south.

For this forecast period, far eastern regions may still be dealing with a little light precipitation from the above-mentioned storm system. Should this system end up tracking a little farther east, eastern regions may be dealing with a second measurable snowfall event. Behind this system, the weather models show high pressure dropping in from the north, bringing clearing skies and continued cold temperatures. Expect temperatures to be at or slightly below the usual temperature range for this time of the year.

The weather models then show an area of low pressure tracking through our region on Friday and Saturday. Southern regions look to be warm enough for the precipitation to fall as rain, while areas to the north will see mostly snow. All areas will likely see some snow late on Saturday as the cold front sweeps through.

It then looks like a strong area of high pressure will develop over the central U.S. during the first half of next week. This high should help to bring mainly sunny skies along with slowly warming temperatures, as our winds gradually switch to westerly and then southwesterly. Expect daytime highs to be pushing into the low teens by Wednesday or Thursday, with overnight lows in the 0 to -3 C range.

Usual temperature range for this period: Highs, 6 to 18 C; lows, -4 to 6 C.
