The seasonal temperatures we have been seing will be coming to an end soon. A major Colorado Low is expected to develop over the next few days and bring heavy snowfall to the Prairies, including southern Manitoba and parts of northwestern Ontario by Sunday. Uncertainty on the track of the system exists as is usual in these types of systems. Just keep in mind that the potential is there for up to 30 cm of snow Friday through to early Sunday for all of southern Manitoba. Hopefully we'll have a better idea on specifically who gets this heaviest snow soon.
Meanwhile, there will be the potential for a few lightning strikes this evening as a low pressure system moves through the province. Nothing significant expected, albeit the fact that lightning is unusual at this time of year. Lightning and thunder has already been reported near Winnipeg near 7:30 PM.
