Warmer weather is on the way for Winnipeg this week as another surge of mild pacific air crosses the Prairies. Temperatures will push well past 0°C on Thursday, with several record highs at risk of being broken across Southern Manitoba.
Warm air will surge across the Prairies with a low pressure system that will track across the Central/Northern Prairies Wednesday/Thursday. Those of us in the Southern Prairies will get to enjoy a nice early-January day where temperatures will reach between 5°C and 10°C by Thursday afternoon with relatively light winds.
Temperatures should be restricted by the snow cover, and I’d like to see a solidly southwest wind to get daytime highs as high as currently forecast (+7°C for Winnipeg).
Currently, winds are forecast to shift from southerly to westerly in the afternoon, however if the troughing ahead of the low is not as deep as currently forecast, southerly winds could prevail in the RRV and keep our temperature significantly lower. That being said, I’d be willing to pin the daytime high for Winnipeg to be about 6°C, reached late in the afternoon. This temperature is well above the -16°C it reached last year on January 5th, the -13.5°C on January 5th, 2010, and the -24°C it reached on January 5th 2009.
The average daytime high temperature for January in Winnipeg is -12.7°C, and the warmest temperature on record for any day in January in Winnipeg is 7.8°C, set on January 23, 1942. The current record high for January 5th is 4.3°C, set in 1984. We will definitely be well above our average daytime high on Thursday and most likely break the old daily record. Is it enough to break the all-time temperature record for January in Winnipeg? Let us know what you think in the comments!
