Roller Coaster Pattern Setting Up

This week will feature wild swings in the weather. Conditions will range from warm to chilly to snowy, with the weather varying from one day to the next.

A low pressure system will bring light snow to southern Manitoba on Monday

Monday

Monday

Chance of Snow Late
-10°C / -18°C

Today will be a bit cooler than the conditions we’ve experienced lately. High temperatures will be around the -10°C mark, with southerly winds. We’ll also see some snow begin to move into Western Manitoba from Saskatchewan in the morning or early afternoon. Total accumulations in Western Manitoba are expected to range from 2 to 5cm. The Red River Valley will be right on the edge of this area of snow, so we may end up with a couple centimetres if the snow pushes into the valley.

Tuesday

Tuesday

Decreasing Cloudiness
-11°C / -25°C

Tuesday will remain on the cooler side, though temperatures will remain near or slightly above normal. Highs will once again be near -10C, with a breezy north-west wind, but no precipitation is expected. We’ll cool down into the minus twenties on Tuesday night, but those cold temperatures will be short-lived.

Wednesday

Wednesday

Mainly cloudy. Chance of Flurries. Risk of Freezing Rain or Ice Pellets.
2°C / -18°C

By Wednesday a powerful low pressure system will send warm air cascading across the Prairies. The cold air from Wednesday morning will be scoured out from Southern Manitoba by the afternoon as temperatures rise above zero in most areas. However, this warm air will be accompanied by very strong winds. Southerly winds of 40km/h gusting to 60km/h in the morning will switch to westerly winds of 40-50km/h gusting to 60-70km/h in the afternoon. These warm temperatures should make the snow more difficult to blow around, though some blowing is possible in the morning before we warm up.

Some light snow will be possible on Wednesday in association with this low pressure system. Larger snowfall amounts will be possible if the system tracks further south than currently expected. In addition to the snow, there may even be a bit of freezing rain or ice pellets because that warm air may melt snowflakes as they descend from the clouds. Unfortunately, the cold front associated with this low will pass through on Wednesday night, sending in colder air for Thursday.

Thursday and Beyond

Warmer than normal weather is being forecast by the NAEFS model for the second half of January

Thursday looks to be our coldest day for the next while, with high temperatures near -20C and gusty winds making it feel much cooler. However, besides Thursday It appears we will continue to see temperatures near or slightly above normal for the next while. Long range models continue to suggest that the second half of January will be warmer than normal, though we will still likely see the odd cold day here or there. No major weather systems are in the forecast, but this pattern will probably continue to send a parade of clipper systems coming out of Alberta, bringing the chance for light snow every few days.
