Forecast: The battle between warm and cold begins

Issued February 6, 2017 – Covering the period from February 8 to February 15, 2017

After a series of systems brought clouds and occasional light snows to start the week, cool high pressure will lead this forecast period. While it does look like milder air will move in a little later, it is going to be a struggle to overcome the cold air parked to our northeast.

High pressure will slide by to our southwest on Wednesday and Thursday, bringing mainly sunny skies along with cold temperatures. Expect daytime highs to only make it to around -18 C, with overnight lows in the -25 C range. We’ll then see a series of quick-moving lows track from the northwest to the southeast over the remainder of this forecast period. As each low approaches we’ll see clouds, light snow and warmer temperatures move in. This will then be followed by clearing skies and a short cool-down before the next low moves in.

The first low is expected on Friday, with the best chances of snow over central and eastern regions. Daytime highs on Friday may make it above 0 C over extreme southern areas, cooling to around -8 C over central regions. A second low is forecast to quickly follow late in the day on Saturday, once again bringing with it clouds and a little light snow. We will see a very quick shot of cooler air overnight Saturday and into Sunday morning.

Yet another low will track in out of the northwest late on Sunday and into Monday morning. This low is currently forecasted to take a slightly more northerly and easterly track, with only far northern and eastern areas expected to see a quick shot of snow. One final low will then zip by late Tuesday or Wednesday, tracking even further north and east. This low will be followed by a brief shot of cold high pressure before warmer air moves in late next week.

Usual temperature range for this period: Highs, -19 to -3 C; lows, -32 to -12 C.
