Crazy Week of Weather Ahead!

Another period of active weather is in store for our week ahead, as several systems cascade through our region bringing multiple chances for precipitation. The question remains will it be rain or snow?

The weather for our week will be fair with temperatures cooling to the low single digits for the night ahead, though a few places could reach the freezing mark. A low pressure system (cyclone) will affect the region tonight and through the day tomorrow, bringing rain to the region within the next few hours persisting through the day tomorrow. There could be a few embedded thunderstorms (a rarity in October) tomorrow afternoon/evening within the rain as moisture is drawn up from the south ahead of the system. The main threat region for thunderstorms will be in the Red River Valley along a line from Warren through Winnipeg south to Altona towards the Ontario Border, and north to Victoria Beach and Powerview. Pretty much all of Eastern Manitoba and half of the Red River Valley, including Winnipeg up into the interlakes. If thunderstorms don't occur there will likely be showers at times that could be heavy. As for temperatures on Tuesday with the rain and thunderstorms they will be fairly similar to the day we had today likely sitting in the high single digits to low teens. Once everything clears out we will recieve rainfall amounts up to the 5 and 15mm range with higher amounts in thunderstorms, which always is a given. 

As our weather system departs on the day Wednesday we will be left with cooler weather as cold air sweeps in from the West making for a chilly start to our second half of the week. Temperatures for Wednesday will be stuck in the mid single digits with a gusty westerly wind.


There has been a lot of chatter over Twitter and the web about our weather this week. Some weather models have been suggesting that portions of Southern Manitoba could be impacted by a colorado low pressure system on Thursday and Friday. However other models have come to the conlclusion of little nothing in terms of precipitation during Thursday and Friday. Conclusions? It remains unlikely that Southern Manitoba will be recieving a major blizzard at the end of the week. Most models show a moderate strength (fairly deep) low pressure system sliding past us through Minnesota and Northwest Ontario heading into Illinois and Michigan. Overall we may see flurries or some rainshowers but we won't be seeing a full fledged winter storm, it will be too far away for us to recieve it's main impacts.

At this time it appears we won't be seeing a significant amount of snow, though always expect the unexpected in mother nature. You may never know what comes out of the box.
