Clouds will increase and thicken throughout the day today and winds will gradually increase to around 30 km/h this afternoon from the southeast. Despite the cloud, we should manage to reach about 7 or 8°C in Winnipeg today.... which seems very nice, but is still a good 5°C below normal.
A fairly intense storm system moves in tonight. This system is quite tough to forecast across southern Manitoba due to concerns of precipitation type. Nonetheless, in Winnipeg, it is expected at this point that most of the precipitation will likely stay as rain, but some snow may mix in at times. Rain may be steady at times with 8-13 mm possible... which would be our most significant rainfall since September, 7 months ago. Areas to our north and northwest in the Parkland and Interlake regions will not be so lucky. Looks like a major snow event for them, especially in the Riding Mountain and Dauphin areas where 20 + cm is possible.
With precipitation ending early in the morning, skies should clear somewhat in the afternoon tomorrow. We should reach around 10°C.
The remainder of the weekend looks reasonable with seasonal highs in the low to mid teens for Sunday, and possibly a few degrees cooler on Monday. A few showers are possible Sunday night, but shouldn't amount to much.
Next system to watch will be mid-late week with a major system south of the border. There is the potential for a significant rain event here Wednesday through to Friday... but it is uncertain how much we'll be impacted at this point.
At this point, an extended period of above normal temperatures is not to be seen yet. Note that normal highs next week are in the 13-16°C range using 1981-2010 normals.
