Blowing and drifting snow yesterday carved out some nice drifts |
Roads are slippery and snow covered |
Either way, the bulk of the storm will stay to our south in North Dakota, Minnesota, Wisconsin and South Dakota. Locally 20-30 cm of snow is not out of the question in those states. That will be associated with strong winds of 40 to 60 km/h locally. Blizzard and winter storm watches and warnings have been issued for much of those areas. This will definintely be the strongest winter storm in the region since last winter. If you have travel plans in those areas over the next couple days, consider postponing or cancelling those plans if it is not absolutely necessary that you go. It will definitely be quite the storm, the one storm that is likely not worth underestimating.
Back in Manitoba, it is tricky. It likely wont be a major storm for us, though accumulations of 5-10 cm is not out of the question near the US Border. Snowfall amounts will likely decrease sharply the farther north you go. Only 1-3 cm is expected for Winnipeg at this point. Moderately strong winds from the north will likely cause some drifting snow as well. A more detailed forecast will be provided tomorrow.
Current expected track of Colorado Low from Tuesday to Thursday |
Later in the week, yet another system. This time it appears both an Alberta Clipper and Colorado Low could form. These setups are often fairly difficult to predict, and often fool the models. The transfer of energy and moisture from the Colorado Low to the Clipper is often hard to predict. At this point, it appears like we may see about 2-5 or 5-10 cm in most of southern Manitoba Friday, but that could change as the week goes on.
Spectacular day filled with sun, light winds and mild temperatures, and a bit of melting in the sun. Around -2°C in the city this afternoon, though cooler at airport with the snow-covered fields, at around -5°C so far.
ReplyDeleteModels returning with the idea of a miss for southern Manitoba tomorrow. We may still get some flurries, and it definitely will be cloudier, though not anything significant. Looks like the flurries will be more dominant tomorrow night than during the day as well. Perhaps a cm at most for most areas, though at this point it really looks like just a dusting.
ReplyDeleteSteadier snow looks to develop Thursday night and Friday. It doesn't look like a very heavy snow, rather a light or moderate snowfall, keeping accumulations a little lower. 2-5 or 5-10 cm still the forecasts for now. Although as stated in the post, things are uncertain considering we could be talking about 2 systems; a Colorado Low and an Alberta Clipper. Energy transfer between the both is always uncertain this far off, so stay tuned...
Severe thunderstorms, with tornado watches in Kansas and Nebraska this evening! Getting closer, can't wait for our turn! :P Ok maybe I'm getting a little ahead of myself, we've got a ways until that. Thunder is possible though as close as southern Minnesota and South Dakota tonight with the snow and rain. Powerful Colorado Low shaping up as we speak, with pressure of 984 mb at its centre in Nebraska early this evening. 20-30 cm still expected in parts of Minnesota, Nebraska and Minnesota along with blizzard conditions.

For comparison, 984 mb would be comparable to the pressure in a category 1 hurricane in the Atlantic. (984 mb = 98.4 kPa)
ReplyDeleteSeveral tornadoes reported south of the border yesterday and today, from Nebraska/Kansas across to southern Missouri to Illinois and Kentucky. At least 9 or 10 people have been killed so far. More in depth story by following this link:

The system Friday at this point is looking less and less severe for us, though it is still not 100% certain. It appears at this point that the Colorado Low (another one, not the same one as yesterday/today) that is expected to form tomorrow will keep most of its energy to our south and east and affect mainly Ontario and south of the border. We will still get some snow with the Clipper though, but 2-5 cm looks like the best bet at this point.
ReplyDeleteWorking on the February summary tonight, so hopefully I'll have it finished by evening, or tomorrow afternoon at the latest.
ReplyDeleteAnd just how warm actually was this winter? How does this winter rank? I'll have the answers either tomorrow afternoon or Friday morning in a new post. Be sure to check around for that.. :)
Boy if you believe the current model predictions, spring is very close. GFS for instance is showing temperatures approaching double digits by the second week of March, with temperatures approaching 20 C near Windsor in extreme southwestern Ontario. It's been showing a dramatic warm-up in March for some time, so it will be interesting to see if it comes true. Every month since last July has been above normal in temperatures, at this point it appears March will follow that trend.
ReplyDeleteFebruary summary is finished. You can view it in the ''Monthly Summaries'' tab at the top of the page. I kept it a little shorter than January's summary, as I found January's summary was a little lengthy. I just put what I found was most important to point out.
ReplyDeleteAs for the current weather talk:
A rare thunderstorm event impacted southern Ontario last night. Follow the link below for a more detailed story with pics and a video.

Flurries will begin this evening, and become more organised overnight and tomorrow for the Winnipeg area. Flurries are widely scattered so far this afternoon, especially in the southwest. 2-5 cm in general is expected with this system by tomorrow night, with locally higher amounts of 5-10 cm possible, especially south of the Trans-Canada. Might be needing the snow shovel again..
ReplyDeleteCool down back to seasonal values for the weekend, then at this point it appears like a big warmup for early next week, with temperatures above zero possible.
