Forecast: Nice early-spring weather to continue

Issued March 12, 2018: Covering the period from March 14 to March 21, 2018

This map shows the total amount of precipitation that fell during the seven-day period ending March 8, catching the snowstorm that hit most of southern and central Manitoba along with a good part of central and eastern Saskatchewan. The heaviest precipitation fell in Saskatchewan, with some areas seeing over 40 mm. Across Manitoba, amounts were a little lighter, ranging from 10 to 30 mm.

Last week’s forecast played out fairly close to what weather models predicted, with a few minor exceptions. Western regions saw a little more cloud and occasional light snow last Wednesday and Thursday, while temperatures to start the week were a little cooler than forecast, thanks to a weak backdoor cold front that moved in from the northeast last Monday.

For this forecast period, it looks like we’ll still see a bit of a warm-up to begin with as the area of high pressure that brought the sunny skies earlier this week slowly slides off to the southeast. Combine this with a digging area of low pressure to our west and this will result in mild air working its way northward, just edging into our region. Expect daytime highs Thursday and Friday to be in the +3 to +6 C range, with overnight lows around -10 C.

The western low is then forecast to break into a couple of pieces, with the first part working toward the north and then west across the central and northern Prairies. This low will bring some clouds along with the chance of showers or flurries overnight Friday and into Saturday. Weak high pressure is then forecast to build across the southern Prairies, bringing a return to sunshine and continued mild temperatures on Sunday. The second piece of energy from the western low is then forecast to develop into a Colorado low on Monday. Currently, it looks like the weak ridge of high pressure forecast to develop across our region will keep this low well to our south. So, we should expect sunny skies on Monday and Tuesday with maybe some high cirrus clouds working in across extreme southern regions.

Seasonable temperatures are expected on Wednesday and Thursday as another area of low pressure begins to work its way inland from the Pacific. While this part of the forecast is a long way off, the current weather models show this low affecting our region late next week, bringing with it a mixed bag of precipitation.

Usual temperature range for this period: Highs, -8 to +4 C; lows, -21 to -8 C.
